The herd is 50% Friesian with the remainder Friesian-Jersey crosses.

Did you know that cows are considered to be 'empty' when their milk supply has dropped to 10 litres at milking.

Check out Mastitis control which has been very successful on your farm – the BMCC( bulk milk cell count) hovers around 100,000.

Your farm Milk Production Target is: 260,000 kgMS [kilograms of milk solids]. Cost of Production target: $5 kgMS. And the grain feed budget for the year is $150,000 + GST.

From the farm information provided, what would be the approximate per cow production of kgMS required in order to achieve the milk production target?

600

520

840

490

The approximate per cow **production** of kgMS required in order to achieve the milk production target is 6,000 kgMS.

Therefore, the correct option is 600.

The Friesian-Jersey crosses will also have a slightly different milk **production rate**, so it is difficult to determine an exact rate.

Using a milk production rate of 6,000 litres per year as an estimate for both the Friesian and Friesian-Jersey crosses, the per cow production of kgMS required to reach the milk production target can be calculated as follows:

Total milk production target = 260,000 kgMS

Total number of cows = (50/100)* Total number of cows (Friesian) + (50/100)* Total number of cows (Friesian-Jersey crosses)= 0.5x + 0.5y

Total milk produced by the Friesian cows = 0.5x * 6,000 litres per cow

= 3,000x

Total milk produced by the Friesian-Jersey crosses

= 0.5y * 6,000 litres per cow = 3,000y

Total milk produced by all the cows

= Total milk produced by the Friesian cows + Total milk produced by the Friesian-Jersey crosses

= 3,000x + 3,000y kgMS

Approximate per cow production of kgMS required to achieve the milk production target

= (3,000x + 3,000y) / (0.5x + 0.5y)

= 6,000 kgMS / 1

= 6,000 kgMS

The approximate per cow production of kgMS required in order to achieve the milk production target is 6,000 kgMS. Therefore, the correct option is 600.

= Problem 1. Let {Xn}=1 be a sequence of random variables such that Xn has N(0,1/n) distribution. Do the Xn have a limit in distribution, and if so, what is it?

F(Y) = (1/2) [ 1 + erf(Y/(√2√n))] We can see that, as n → ∞, the above **expression** F(Y) approaches the **distribution function** of N(0,1) distribution which is given by, G(Y) = (1/2) [ 1 + erf(Y/(√2))]

Given a sequence of **random variables** {Xn} where Xn has N(0,1/n) distribution.

To determine if {Xn} have a limit in distribution and what is it, let us find the distribution function of the sequence.

Suppose F(x) be the distribution function of {Xn} and Y be any real number.

Then, we have,

F(Y) = P({Xn} ≤ Y)

Here,{Xn} ≤ Y

Xn ≤ Y for all n∈N

And we know that Xn has N(0,1/n) distribution, so we can write,

P({Xn} ≤ Y) = [tex]\int_{-\infty}^{Y}f_{X_n}(x) dx[/tex]

where, [tex]f_{X_n}(x)[/tex] is the **probability density function** of Xn which is given by

f_{X_n}(x) = (1/√(2π/n)) e^((-x^2)/(2/n))

Next, we integrate [tex]f_{X_n}(x)[/tex] with **limits** -∞ and Y, we get,

[tex]\int_{-\infty}^{Y}f_{X_n}(x) dx[/tex]

= [tex]\int_{-\infty}^{Y} (1/\sqrt2\pi/n)) e^{((-x^2)/(2/n))} dx[/tex]

= (1/2) [ 1 + erf(Y/(√2√n))]

where, erf(z) = (2/√π) ∫_{0}^{z} e^(-t^2) dt is the error function.

Now, we have, F(Y) = (1/2) [ 1 + erf(Y/(√2√n))]We can see that, as n → ∞, the above expression F(Y) approaches the distribution function of N(0,1) distribution which is given by,G(Y) = (1/2) [ 1 + erf(Y/(√2))]

Thus, {Xn} has a limit in distribution and it is N(0,1) distribution.

To evaluate the **integral** ∫√√x⋅(13x) dx, we can make a **substitution **u = √x. Then, du/dx = 1/(2√x) and dx = 2u du.

Making the substitution, the integral becomes:

∫(√u)⋅(13u²)⋅(2u du)

Simplifying, we have:

26∫u^3/2 du

**Integrating **term by term, we add 1 to the **exponent **and divide by the new exponent:

26 * [(u^(3/2 + 1))/(3/2 + 1)] + C

= 26 * [(u^(5/2))/(5/2)] + C

= (52/5) * u^(5/2) + C

Now, substituting back u = √x, we have:

(52/5) * (√x)^(5/2) + C

= (52/5) * (x^(1/4)) + C

So, the evaluated integral is (52/5) * (x^(1/4)) + C.

To check our result, we can **differentiate **the obtained expression and verify if it matches the original integrand.

Differentiating (52/5) * (x^(1/4)) + C with respect to x, we get:

d/dx [(52/5) * (x^(1/4))] + d/dx [C]

= (52/5) * (1/4) * x^(-3/4)

The given **function** is:

g(x) = 2x² + 4/x^4.

To find the average **rate** of change of g(x) over the interval [-4, 3], we use the formula as shown below:

**Average** rate of change = (g(3) - g(-4))/(3 - (-4))

First, we need to find g(3) and g(-4) as follows:

g(3) = 2(3)² + 4/(3)⁴= 18.1111 (rounded to four decimal places)

g(-4) = 2(-4)² + 4/(-4)⁴= 2.0625 (rounded to four decimal places)

Now, substituting the values of g(3) and g(-4) in the formula of average rate of **change**, we get:

Average rate of change = (18.1111 - 2.0625)/(3 - (-4))= 3.3957 (rounded to four decimal places)

Therefore, the average rate of change of g(x) = 2x² + 4/x^4 on the interval [-4, 3] is approximately **3.3957**.

Test at 5% level of significance whether the bus owner's claim is true.

There is** enough** evidence to infer that the population mean is different from 15 in the first scenario, but not enough evidence to support the bus owner's claim in the second scenario.

In the first **scenario**, the statistics practitioner randomly sampled 500 observations with a mean of 14 and a standard deviation of 25. To test whether there is enough evidence to infer that the population mean is different from 15, a hypothesis test is conducted. The null hypothesis (H₀) states that the population mean is equal to 15, while the alternative hypothesis (H₁) suggests that the population mean is different from 15.

By calculating the **test statistic**, comparing it to the critical value, and considering the level of significance (-0.01), it is determined that there is enough evidence to reject the null hypothesis. This implies that the population mean is indeed different from 15.

In the second scenario, the bus owner claims that the average number of trips per week is more than 45. A random sample of 10 buses was selected, resulting in an average of 40 trips with a variance of 4. To test this claim, a hypothesis test is conducted at a 5% level of significance. The null **hypothesis** (H₀) assumes that the average number of trips is 45 or less, while the alternative hypothesis (H₁) suggests that the average is greater than 45.

By calculating the test statistic and comparing it to the critical value, it is determined that there is not enough evidence to reject the null hypothesis. Therefore, the statistical data does not support the bus owner's claim that the **average** number of trips is more than 45 per week.

Suppose that an electronic system contains n components that function independently of each other and that the probability that component i will function properly is pį, (i = 1,..., n). It is said that the components are connected in series if a necessary and sufficient condition for the system to function properly is that all n components function properly. It is said that the components are connected in parallel if a necessary and sufficient condition for the system to function properly is that at least one of the n components functions properly. The probability that the system will function properly is called the reliability of the system. Determine the reliability of the system, (a) assuming that the components are connected in series, and (b) assuming that the components are connected in parallel.

(a) If the **components** are connected in series, the system will function properly only if all n components function properly. The probability that a single component functions properly is pᵢ for each i = 1, 2, ..., n.

Since the components function independently, the probability that all n components function properly is the product of their individual probabilities. Therefore, the reliability of the system when connected in series is given by:

**Reliability** (series) = p₁ * p₂ * ... * pₙ

(b) If the components are connected in parallel, the system will function properly if at least one of the n components functions properly. The **probability** that a single component functions properly is pᵢ for each i = 1, 2, ..., n.

The reliability of the system when connected in parallel can be calculated using the complement rule. The probability that the system fails (i.e., none of the components function properly) is the complement of the probability that at least one component functions properly. Therefore, the reliability of the system when connected in parallel is given by: Reliability (parallel) = 1 - (1 - p₁)(1 - p₂)...(1 - pₙ).

This formula assumes that the events of each component **functioning** properly or failing are mutually exclusive.

These formulas provide a way to calculate the reliability of the system based on the probabilities of individual component functioning properly.

Use implicit differentiation to find dy/dx. 3xy - 2x + y = 1 기 dx 11

By applying the **product rule **and chain rule, we can solve for dy/dx in terms of x and y. For the equation 3xy - 2x + y = 1, the **derivative **dy/dx is equal to (2 - 3y) / (3x - 1).

To find the derivative dy/dx using **implicit **differentiation, we differentiate both sides of the equation with respect to x. Applying the product rule and chain rule, we obtain:

d/dx (3xy) - d/dx (2x) + d/dx (y) = d/dx (1)

Using the product rule, the derivative of 3xy with **respect **to x is given by:

d/dx (3xy) = 3x(dy/dx) + 3y

The derivative of 2x with respect to x is simply 2, and the derivative of y with respect to x is dy/dx.

Since the derivative of a constant (1 in this case) is 0, the** right-hand side** becomes 0.

Substituting these derivatives into the equation, we have:

3x(dy/dx) + 3y - 2 + dy/dx = 0

Combining** **like terms, we obtain:

(3x + 1) (dy/dx) + 3y - 2 = 0

Now, we can isolate dy/dx to find the derivative:

(3x + 1) (dy/dx) = 2 - 3y

Dividing both sides by (3x + 1), we get:

dy/dx = (2 - 3y) / (3x - 1)

Therefore, the derivative dy/dx for the equation 3xy - 2x + y = 1 is given by (2 - 3y) / (3x - 1).

Next, we approximate the **integral **over each subinterval using the formula for the area of a **trapezoid**: ΔI ≈ (h/2) * (f(a) + f(b)), where h is the width of each subinterval, f(a) is the function value at the left endpoint, and f(b) is the function value at the right endpoint of the subinterval.

For each subinterval, we evaluate the function sin²(√Tt) at the left and right endpoints. We sum up all the approximations for the subintervals to obtain the overall approximation of the **integral**. Since n = 20, we will have 20 subintervals and 21 function evaluations (including the endpoints). Finally, we multiply the sum by the width of each subinterval to get the final approximation of the **integral **I.

The mean amount of **snow per day** is equal to 19 cm **snow per day**.

In Mathematics and Geometry, the** mean** for this set of data can be calculated by using the following formula:

Mean = [F(x)]/n

For the total amount of **snow** based on the **frequency**, we have;

Total amount of snow (s cm), F(x) = 5(8) + 15(10) + 25(7) + 35(2) + 45(3)

Total amount of snow (s cm), F(x) = 40 + 150 + 175 + 70 + 135

Total amount of **snow **(s cm), F(x) = 570

Now, we can calculate the** mean** amount of **snow** as follows;

Mean = 570/30

Find a basis for the subspace spanned by the given vectors. What is the dimension of the subspace?

[1 -1 -2 5]^T

Therefore, the basis for the **subspace **is [tex]{[1, -1, -2, 5]^T}[/tex], and the dimension of the subspace is 1.

To determine the basis for a subspace spanned by a given vector, we need to find a set of linearly independent vectors that can generate all possible vectors within that subspace.

In this case, we are given the vector [tex][1, -1, -2, 5]^T[/tex]. To determine if this vector can be a basis for the subspace, we need to check if it is linearly **independent**.

Since the vector is non-zero, it is not a scalar multiple of the zero vector, and therefore, it is not trivially dependent. This means that the vector [tex][1, -1, -2, 5]^T[/tex] can be considered as a potential basis vector for the subspace.

To confirm that it is indeed a basis vector, we need to check if it can generate all possible vectors within the subspace. Since the vector is non-zero, it spans a one-dimensional subspace, which means that any vector in the subspace can be expressed as a scalar multiple of the given **vector**.

In a game, a character's strength statistic is Normally distributed with a mean of 340 strength points and a standard deviation of 60. Using the item "Cohen's weak potion of strength" gives them a strength boost with an effect size of Cohen's d=0.2. Suppose a character's strength was 360 before drinking the potion. What will their strength percentile be afterwards? Round to the nearest integer, rounding up if you get a S answer. For example, a character who is stronger than 72 percent of characters (sampled from the distribution) but weaker than the other 28 percent, would have a strength percentile of 72.

The character's strength **percentile**, rounded to the nearest **integer**, would be 63 after drinking the potion.

To determine the character's strength **percentile** after drinking the potion, we need to calculate the z-score for their strength value and then find the corresponding percentile from the standard normal distribution.

First, let's calculate the **z-score** using the formula:

z = (X - μ) / σ

where X is the character's strength value, μ is the mean, and σ is the standard deviation.

X = 360 (character's strength after drinking the potion)

μ = 340 (mean)

σ = 60 (standard deviation)

z = (360 - 340) / 60

z = 20 / 60

z = 1/3

Now, find the percentile corresponding to this z-score using a standard normal distribution table or a calculator. The percentile represents the percentage of values that are lower than the given z-score.

Looking up the **z-score** of 1/3 in a standard normal distribution table or using a calculator, we find that the corresponding percentile is approximately 63.21%.

Therefore, the character's strength percentile, rounded to the nearest integer, would be 63 after drinking the potion.

Find the area of the triangle having the given measurements. Round to the nearest square unit. C=95%, a 5 yards, b=9 yards *** OA. 90 square yards OB. 22 square yards OC. 45 square yards OD. 2 square

Correct option is B. To find the area of a triangle, we can use the formula: Area = (1/2) * base * height

In this case, side "a" has a length of 5 yards and side "b" has a length of 9 yards. We are also given the **measure** of angle C, which is 95°.

To find the height of the **triangle**, we can use the sine function:

sin(C) = opposite/hypotenuse

sin(95°) = height/9

height = 9 * sin(95°)

Now we can calculate the area using the formula: Area = (1/2) * 5 * (9 * sin(95°))

Using a calculator, we can find the value of sin(95°) ≈ 0.996.

Area = (1/2) * 5 * (9 * 0.996)

Area ≈ 22.41 square yards

Rounding to the nearest **square** unit, the area of the triangle is approximately 22 square yards (Option OB).

Use the standard second-order centered-difference approximation to discretize the Poisson equation in one dimension with periodic boundary conditions: u"(t) u(0) f(t), 0

The standard second-order centered-difference approximation to discretize the **Poisson equation** in one dimension with periodic boundary conditions is shown below:

Given the Poisson equation in one dimension with periodic boundary conditions:

u''(x) = f(x), 0 < x < L,u(0) = u(L),

where u is the unknown function, f is the known forcing function, and L is the length of the domain.

The standard second-order centered-**difference **approximation for the second derivative is:

(u_{i+1}-2u_i+u_{i-1})/(Δx^2)=f_i

where Δx is the spatial step size, and f_i is the value of f at the ith **grid **point.

The **periodic **boundary conditions imply that u_0=u_N, where N is the number of grid points.

Thus, we can write the approximation for the boundary points as:

(u_1-2u_0+u_N)/(Δx^2)=f_0and(u_0-2u_1+u_{N-1})/(Δx^2)=f_1

The solution to the **discretized equations** can be obtained by solving the linear **system of equations** [tex][A]{u} = {f}[/tex], subject to the boundary condition [tex]u_0 = u_{N-1}[/tex].

To discretize the **Poisson equation** in one dimension with periodic boundary conditions, we can use the standard second-order centered-difference approximation.

Let's consider a **uniform grid** with N points in the interval [0, L] and a grid spacing h = L/N.

The grid points are denoted as [tex]x_i[/tex] = i × h, where i = 0, 1, 2, ..., N-1.

We can approximate the **second derivative** of u with respect to x using the centered-difference formula:

[tex]u''(x_i) \approx (u(x_{i+1}) - 2u(x_i) + u(x_{i-1})) / h^2[/tex]

Applying this approximation to the **Poisson equation** u''(x) = f(x), we have:

[tex](u(x_{i+1}) - 2u(x_i) + u(x_{i-1})) / h^2 = f(x_i)[/tex]

To handle the periodic boundary conditions, we need to impose the condition u(0) = u(L).

Let's denote the value of u at the first grid point u_0 = u(x_0) and the value of u at the last grid point [tex]u_{N-1} = u(x_{N-1})[/tex].

Then the **discretized equation** at the boundary points becomes:

[tex](u_1 - 2u_0 + u_{N-1}) / h^2 = f_0 -- > u_0 = u_{N-1}[/tex]

Now, we have N **equations** for the N unknowns [tex]u_0, u_1, ..., u_{N-1}[/tex], excluding the boundary **condition equation**.

We can represent these equations in matrix form as:

[tex][A]{u} = {f}[/tex],

where [A] is an (N-1) x (N-1) tridiagonal matrix given by:

[A] = 1/h² ×

| ... ... ... ... ... ... |

| 0 0 0 ... -2 1 |

| 1 0 0 ... 1 -2 |

and {u} and {f} are column vectors of size (N-1) given by:

[tex]{u} = [u_1, u_2, ..., u_{N-2}, u_{N-1}]^T,[/tex]

[tex]{f} = [f_1, f_2, ..., f_{N-2}, f_{N-1}]^T,[/tex]

with [tex]f_i = f(x_i) for i = 0, 1, ..., N-1[/tex] (excluding the boundary point f(x_0)).

The solution to the discretized equations can be obtained by solving the linear system of equations [tex][A]{u} = {f}[/tex], subject to the boundary condition [tex]u_0 = u_{N-1}[/tex].

The relation [tex]R = { (a,b) | a/b e Z, b > 0}[/tex] is not **symmetric**. Relation is anti-symmetric and **transitive**, it is not an equivalence relation.

Given the relation R as

[tex]R = {(a, b) | a/b ∈ Z, b > 0},[/tex]

where A and B are sets of real **numbers**. This is a relation on A, as well as a relation on B.

For this relation to be symmetric, for all (a, b) ∈ R, (b, a) should also be in R. Assume that a and b are two non-zero real numbers, a ≠ b. For the given relation to be symmetric, we need to show that if a/b is an integer, then b/a is also an integer.

Hence, (a, b) ∈ R

⇒ a/b ∈ Z.

This implies that there exists an integer k such that a/b = k.

Solving for b/a, we get b/a = 1/k.

Since k is an integer, 1/k is also an integer

if and only if k = 1 or k = -1.

Thus, for the given relation to be symmetric, a/b = 1 or -1. This is not true for all values of a and b, and hence the relation is not symmetric.

A relation R is anti-symmetric if and only

if (a, b) ∈ R and (b, a) ∈ R implies a = b.

For the given relation to be anti-symmetric, we need to show that if a/b and b/a are integers, then a = b.

Hence, the given relation is **anti**-symmetric.

A relation R is transitive if and only

if (a, b) ∈ R and (b, c) ∈ R imply (a, c) ∈ R. For the given relation to be transitive,

we need to show that if a/b and b/c are integers, then a/c is also an integer.

Assume that a/b and b/c are integers. This implies that there exist integers m and n such that

a/b = m and

b/c = n.

Multiplying these equations, we get a/c = mn.

Therefore, a/c is also an integer.

Mathews complained of chronic excess gas, abdominal bloating, distension, diarrhea and abdominal pain. The patient reported that his symptoms have been re- occurring and have fluctuated in intensity over the past eighteen months. Mathews initially theorized that this condition was the result of a poor diet, consisting mainly of greasy "fast" foods. Over the last two months Mathews had changed his eating habits and lifestyle to include healthy foods and exercise. This modification did not have any effect on his condition and he was concerned about his dramatic weight loss over the past three months. Mathews appeared distraught and genuinely concerned for his health. Day 1-Part A - Tho Anatomy Dr. Andersen, a specialist on the human gastronomic system, determined that many of the symptoms elicited by Mathews could be directly related to a problem in either the small or large intestine. A battery of tests were performed on Mathews, two noteworthy results are described below. The first procedure was performed in the interest of collecting bacterial culture swabs of Mathews' small intestine. A long flexible tube is passed through the nose, down the throat and esophagus and through the stomach. A small camera, attached to the top of the tube recorded every twist and tum of the journey. It was performed under X-ray guidance. The data from both the camera and the x- ray machine were used to create a detailed sketch of Mathews gastronomic tract. Question 1 (10 marks) A specific section of Mathews gastronomic tract can be modeled by the function g(x) = -x +11x -43x'+69x - 36x, where x represents distance traveled by the scope, in cm, and g(x) refers to the vertical height within the body relative to the belly button, in cm. a) Rewrite this equation in factored form. Show all of your work. (5K) b) Use this information to sketch a graph, by hand, of this section of Mathews' small intestine. (2A,T) c) Determine the domain of this function. (1K) d) Bacterial culture samples were taken at two unique points along the journey. Clearly mark these points on your graph. (2A) . At the first turning point • At the only root with order two

a). The **factored form** of the given equation is:

g(x) = (x - (79 + √129)/22) (x - (79 - √129)/22)

b). The vertex of the **parabola** is (3.59, -36.35)

c). At the first turning point, x ≈ 0.61At the only root with order two,

x ≈ 5.67

a) Let's simplify the **expression** for the equation in factored form.

g(x) = -x + 11x - 43x' + 69x - 36x= -x + 11x² - 43x' + 69x - 36x= 11x² - 79x + 69

We can factorize the **quadratic equation** 11x² - 79x + 69 into two binomials by using the quadratic formula.

11x² - 79x + 69 = 0x = [79 ± √(79² - 4(11)(69))] / 22x = (79 ± √129) / 22

Let's factor the given expression as shown below.

(x - (79 + √129)/22) (x - (79 - √129)/22)

Therefore, the factored form of the given equation is:

g(x) = (x - (79 + √129)/22) (x - (79 - √129)/22)

b) The given function represents a quadratic equation, so it is a parabolic function.

Let's calculate the axis of symmetry by using the formula given below.

x = -b / 2a

where a = 11 and

b = -79x = -(-79) / (2 × 11) = 3.59 (rounded to two **decimal places**)

Therefore, the axis of symmetry is x = 3.59 (rounded to two decimal places).

Let's find the y-coordinate of the vertex by substituting the value of x into the given equation.

g(x) = 11x² - 79x + 69g(3.59) = 11(3.59)² - 79(3.59) + 69 = -36.35 (rounded to two decimal places)

Therefore, the vertex of the parabola is (3.59, -36.35) (rounded to two decimal places).

c) The domain of the function is all real numbers, since we can input any value of x into the function.

Therefore, the domain of the function is (-∞, ∞). d)

Let's find the x-coordinates of the two unique points on the graph where the bacterial culture samples were taken by equating the function to zero.

g(x) = 11x² - 79x + 69 = 0

Using the quadratic formula, we get

x = [79 ± √(79² - 4(11)(69))] / 22x = (79 ± √129) / 22

Therefore, the two unique points where the bacterial culture samples were taken are:

x = (79 + √129) / 22x ≈ 5.67 (rounded to two decimal places)

x = (79 - √129) / 22x ≈ 0.61 (rounded to two decimal places)

Therefore, the two unique points are marked on the graph below.

At the first turning point, x ≈ 0.61At the only root with order two, x ≈ 5.67

The number of hours that students studied for a quiz and the quiz grade earned by the respective students (y) is shown in the table below, Find the following numbers for these data = Dy= Find the value of the linear correlation coefficient r for these data. Answer:r= What is the best (whole-number estimate for the quiz grade of a student from the same population who studied for two hours?(Use a significance level of a=0.05.

The **values **are : Σx = 9, Σy = 23, Σxy = 47, Σx² = 27, Σy² = 109.

The value of the linear **correlation coefficient** is 0.9526.

Given that :

x : 0 1 1 3 4

y : 4 4 4 5 6

Σx = 0 + 1 + 1 + 3 + 4 = 9

Σy = 4 + 4 + 4 + 5 + 6 = 23

Σxy = 0 + 4 + 4 + 15 + 24 = 47

Σx² = 0 + 1 + 1 + 9 + 16 = 27

Σy² = 16 + 16 + 16 + 25 + 36 = 109

**Linear correlation **coefficient is :

r = [n (Σxy) - (Σx)(Σy)] / [n Σx² - (Σx)²][n Σy² - (Σy)²]

= [5 (47) - (9)(23)] / [5 (27) - 81][5 (109) - (23)²]

= 0.9526
