Find the quadratic function y = a(x-h)2 whose graph passes through the given points.
(12,-10) and (8,0)

The correct option is b.Type I; Type II.

Rejecting the null hypothesis when it is true is called a type I error, whereas not rejecting a false null hypothesis is called a u type II error.

A type I error occurs when a null hypothesis that is true in the population is rejected. A false positive is an example of this type of error. A type II error occurs if a null hypothesis that is actually false in the population is not rejected. This type of error is known as a false negative.A type II error differs from a type I error in that a type I error rejects the null hypothesis when it is true (i.e., a false positive). The likelihood of making a type I error is equal to the level of significance set for the hypothesis test.

Thus, for the given question, option. b is the correct answer for the blanks in the question.

The dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.

Area A = H.W

Its printed material is either W - 4(2) or W - 8.

Its printed material is H - 6(2)

height = H - 12

The printed area is therefore (W - 8)(H - 12) = 380.

(W - 8)(H - 12) = 380

WH - 12W - 8H + 96 = 380

W(H - 12) - 8H = 284

W = (284 + 8H)/(H - 12)

Put the values in the area;

A(H) = H(284 + 8H)/(H - 12)

A(H) = (284H + 8H²)/(H - 12)

Differentiate with respect to H to find the rate change of area.

A'(H) = [(284 + 16H)(H - 12) - (284H + 8H²)(1)]/(H - 12)²

A'(H) = (284H - 3408 + 16H² - 192H - 284H - 8H²)/(H - 12)²

A'(H) = (8H² - 192H - 3408)/(H - 12)²

A'(H) = 8(H² - 24H - 426)/(H - 12)²

Put A'(H) = 0

8(H² - 24H - 426)/(H - 12)² = 0

Solving;

H = 35. 87 cm

Thus, W = 25.63 cm

Thus, the dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.

Step-by-step explanation: PQRS is 2x the size of ABCD

The value of the required mean of the sampling distribution of sample means is approx. 21 ounces when this process is in control.

Sample mean: The arithmetic mean of the values of the variables in the sample. If the samples are drawn from probability distributions with a common expected value, the sample mean is an estimate of that expected value.

Sample means for all days using formula,

Monday = (23+22+23+24)/4 = 23

Tuesday = (23+21+19+21)/4 = 21

Wednesday = (20+19+20+21)/4 = 20

Thursday = (18+19+20+19)/4 = 19

Friday = (18+20+22+20)/4 = 20

We have to calculate the mean of sampling distribution of sample means.

Mean of the sampling distribution of sample means = Sum of sample means of all days / Number of days

= (23+21+20+19+20)/5

= 20.6 = 21 ounces

Hence, the required mean is approx. 21 ounces.

The equation of the circle on the y-axis is x² +(y-3)² = 36.

Here we have to find the equation of the circle

Data provided:

diameter(d) = 12 units

so radius(r) = 6 units

The center lies on the y-axis

The general equation of the circle:

(x-x1)² + (y - y1)² = r²

where (x1, y1) is the point on the circle.

So by putting x1 = 0 and y1 = 3 and r = 6 as the center lies of y-axis

x² + ( y - 3)² = 6²

x² + (y-3)² = 36

Therefore we get the equation as x² + (y-3)² = 36

The larger number is 15 and the smaller number is 9.

What is substitution method?

In order to solve a system of equations, the substitution method is typically used in mathematics. This approach involves first solving the equation for one variable, then changing the value of the variable in the second equation.

Suppose

'a' be the larger number and 'b' be the smaller number.

As the difference of two numbers is 6.

⇒ a - b = 6        ..(1)

As  two times the smaller is 3 more than the larger.

⇒ 2b = 3 + a        ..(2)

From equation (2),

a = 2b - 3

Substitute the value of 'a' in equation (1)

2b - 3 - b = 6

       b - 3 = 6

            b = 6 + 3

            b = 9

Substitute b = 9 in equation (1),

a - 9 = 6

    a = 6 + 9

    a = 15

Hence, the larger number is 15 and the smaller number is 9.

Answer:

Step-by-step explanation:

This set is closed under scalar multiplications. Statement 1 is false.

This set is a subspace. This statement is also false because this set does not contain a zero vector so it is not a subspace.

This set is closed under vector addition. This is false. Because let v and w be two vectors such that v=(v1,v2); w=(w1,w2).

The set contains the zero vector. Statement 4 is false because the sum of two zero vectors cannot be equal to 1.

Since v and w are vectors satisfying the condition of space so v1+v2=1;w1+w2=1

Now we check whether v+w also belongs to the same space or not.

v+w=(v1,v2)+(w1,w2)=(v1+w1, v2+w2)

We shall check whether components of v+w also add up to 1.

v1+w1+v2+w2=v1+v2+w1+w2=1+1=2

So it means that this space is not closed under addition too.

Consider a vector v=(v1,v2) from the space.

Obviously v1+v2=1

Now let us take a constant 'c'  and consider the behavior of

cv=c(v1,v2)=(cv1,cv2)

Now we check whether components of this vector add up to 1.

cv1+cv2=c(v1+v2)=c\neq 1

which clearly indicates that vectors of this space are not closed under scalar multiplication.

The transformation of the function g ( x ) = | x + 4 | - 2 is

Horizontal shift : Left by 4 units

Vertical shift : Down by 2 units

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs)

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:  y=f(x+c) (same output, but c units earlier)

Right shift by c units:  y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching shift:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be f ( x )

The value of f ( x ) = | x |

Now , the transformation from the first function f ( x ) to g ( x ) is of the form

g ( x ) = | x + 4 | - 2

And , transformation is

y = a | x - h | + k

where the values of y , a , x , h and k are

The value of a = 1

The value of h = -4

The value of k = -2

Now , The Horizontal shift  is given by

Left shift by c units:  y=f(x+c) (same output, but c units earlier)

Right shift by c units:  y=f(x-c)(same output, but c units late)

So , h = -4 means left shift by 4 units

And , The Vertical shift is given by

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

So , k = -2 means down shift by 2 units

Hence , The transformation of the function g ( x ) = | x + 4 | - 2 is

Horizontal shift : Left by 4 units

Vertical shift : Down by 2 units

Using Chebychev's inequality the probability shows an outcome of the experiment between 13 and 31 is equal to 0.9506.

As given in the question,

Mean 'μ' = 22

Standard deviation 'σ' = 2

Apply Chebychev's inequality we have,

P ( | X - μ | ≤ kσ ) ≥ 1 - (1/k²)

Where 'k' is the constant value.

Estimation of  probability  with outcome lies between 13 and 31 using Chebychev's inequality is :

P ( 13 < X < 31 )

= P ( 13 -22 < X - μ < 31 - 22 )

= P ( -9 < X - μ < 9 )

= P ( | X - μ |≤ 9)

= P [ |X - μ | ≤ (9/2) ×2 ]

= P(  |X - μ | ≤ Kσ)

≥ 1 - ( 1/k²)

here k = 9/2

= 1 - (1 / (9/2)²)

= 1 - 4/81

= (81 -4) / 81

= 77/ 81

= 0.9506

Regular price is the cost at which a provider continuously and actively sells goods or services to the general public over an extended period of time.

According to data in the given question,

We have the given information:

Sale discount 33% and the sale price 184.80.

Now, we will calculate the regular price:

Let Regular Price = x

33% Discount of x = 33/100 * x

33% Discount of x = 33x/100

Regular price - 33% Discount = Sale price

x-33x/100=184.80

(100x-33x)/100=184.80

67x/100=184.80

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,

We have to find how much would one kilogram of each kind of candy cost.

We know that,

Let's change the price of cinnamon red hots per kg to c and the price of gummy bears per kg to b.

3c+1b=21
