Answer:

a. Linear

Step-by-step explanation:

The difference is equal between y- values (0.480)

So it is linear change and linear function

Answer:

Linear

Step-by-step explanation:

The hypothese is the function is linear. Lets prove it .

If we divide the difference of 2 any function's values by the difference of the corresponding argument's values we will get the same ratio 0.48(for instance 19.210-18.250=0.96 delete be 2-0=2 will get 0.48)  .

Lets  calculate any other pair of y (function) and x ( argument) :

(20.170-18.730)/(4-1)=1.44/3=48 as we can see we'll get the same ratio 0.48.

That means that function is linear

Answer:

[tex]y =log_e(x+3)[/tex]

Step-by-step explanation:

It is given that the graph corresponds to a natural logarithmic function.

That means, the function [tex]y[/tex] has a natural log (Log with base [tex]e[/tex]) of some terms of x.

It is given that asymptote of given curve is at [tex]x= -3[/tex]. i.e. when we put value

[tex]x= -3[/tex], the function will have a value [tex]y \rightarrow \infty[/tex].

We know that natural log of 0 is not defined.

So, we can say the following:

[tex]log_e(x+a)[/tex] is not defined at [tex]x= -3[/tex]

[tex]\Rightarrow x+a =0\\\Rightarrow x = -a[/tex]

i.e. [tex]x =-a[/tex] is the point where [tex]y \rightarrow \infty[/tex]

a = 3

Hence, the function becomes:

[tex]y =log_e(x+3)[/tex]

Also, given that the graph crosses x axis at x = -2

When we put x = -2 in the function:

[tex]y =log_e(-2+3) = log_e(1) = 0[/tex]

And y axis at 1.

Put x = 0, we should get y = 1

[tex]y =log_e(0+3) = log_e(3) \approx 1[/tex]

So, the function is: [tex]y =log_e(x+3)[/tex]

Answer:

1.     [tex]16 = 4^2[/tex]

2.    [tex]2 = {16}^{\frac{1}{4}}[/tex]

3.    [tex]log_2 y=z[/tex]

Step-by-step explanation:

[tex]1.\ log_2 16=4[/tex]

Write in exponential form

Using the law of logarithm which says if

[tex]log_b A=x[/tex]

then

[tex]A = b^x[/tex]

By comparison;

A = 16; b = 2 and x = 4

The expression [tex]log_2 16=4[/tex] becomes

[tex]16 = 4^2[/tex]

[tex]2.\ log_{16} 2=\frac{1}{4}[/tex]

Write in exponential form

Applying the same law as used in (1) above;

A = 2; b = 16 and [tex]x = \frac{1}{4}[/tex]

The expression [tex]log_{16} 2=\frac{1}{4}[/tex] becomes

[tex]2 = {16}^{\frac{1}{4}}[/tex]

[tex]3.\ 2^z=y[/tex]

Write in logarithm form

Using the law of logarithm which says if

[tex]b^x =A[/tex]

then

[tex]log_b A=x[/tex]

By comparison;

b = 2; x = z and A = y

The expression [tex]2^z=y[/tex] becomes

[tex]log_2 y=z[/tex]

The given equations written in exponential or logarithmic form as the case is is;

1) 2⁴ = 16

2)16^(¼) = 2

3) Log_2_y = z

Usually in logarithmic exponential functions expressions;

When we have;

Log_n_Y = 2

It means that; n² = Y

Applying that same principle to our question means that;

1) log_2_16 = 4

This will now be;

2⁴ = 16

2) log_16_2 = ¼

This will now be;

16^(¼) = 2

3) For 2^(z) = y

We have;

Log_2_y = z

Answer:

67 inches

Step-by-step explanation:

Let's call the height of Louise 'L', the height of Miriam 'M' and the height of Jeffery 'J'.

Then, we can write the following equations and inequations:

[tex]L \leq M - 1[/tex]

[tex]L \geq J + 2[/tex]

[tex]J = 64[/tex]

[tex]M \leq J + 5[/tex]

Substituting J in the second and four inequations, we have:

[tex]L \geq 66[/tex]

[tex]M \leq 69[/tex]

If we assume the maximum value for M, in the first inequation we have that:

[tex]L \leq 68[/tex]

So the height of Uncle Louise is greater than or equal 66, and lesser than or equal 68, so his height could be 67 inches for example.

Answer:

If the value of n gests smaller then the distribution of X would be more skewed, that's a property of the binomial distribution

Step-by-step explanation:

For this problem we are assumeing that the random variable X is :

[tex] X \sim Bin(n,p)[/tex]

If the value of n gests smaller then the distribution of X would be more skewed, that's a property of the binomial distribution and if we don't satisfy this two conditions:

[tex] n p>10[/tex]

[tex]n(1-p) >10[/tex]

Then we can't use the normal approximation

Answer: 108 inches

Step-by-step explanation: The answer would be 108 inches because if you multiply the number that coverts a inch into a foot it would be 12 because 12 inches is equivalent to 1 foot. So you know that 1 foot is equal to 12 inches so you multiply the number of feet by 12. You expression is 9 times 12 and after you multiply the two numbers you get 108 inches.

Answer: 108 inches

Step-by-step explanation: To convert 9 feet into inches, we use the conversion factor for feet and inches which is 12 inches = 1 foot.

Next, notice that we're going from a

larger unit, feet, to a smaller unit, inches.

When we go from a larger unit to a smaller unit, we

multiply 9 by the conversion factor, 12 to get 108.

So 9 feet = 108 inches.

Area of Rectangle A

[tex]Area = 4x^2[/tex]

Area of Rectangle B

[tex]Area = 2x^2[/tex]

Fraction

[tex]Fraction =\frac{2}{3}[/tex]

Step-by-step explanation:

From the attached, we understand that:

The dimension of rectangle A is 2x by 2x

The dimension of rectangle B is x by 2x

Area of rectangle is calculated as thus;

[tex]Area = Length * Breadth[/tex]

Area of Rectangle A

[tex]Area = 2x * 2x[/tex]

[tex]Area = 4x^2[/tex]

Area of Rectangle B

[tex]Area = x * 2x[/tex]

[tex]Area = 2x^2[/tex]

Area of Big Rectangle

The largest rectangle is formed by merging the two rectangles together;

The dimension are 3x by 2x

The Area is as follows

[tex]Area = 2x * 3x[/tex]

[tex]Area = 6x^2[/tex]

The fraction of rectangle A in relation to the largest rectangle is calculated by dividing area of rectangle A by area of the largest rectangle;

[tex]Fraction = \frac{Rectangle\ A}{Biggest}[/tex]

[tex]Fraction =\frac{4x^2}{6x^2}[/tex]

Simplify

[tex]Fraction =\frac{2x^2 * 2}{2x^2 * 3}[/tex]

[tex]Fraction =\frac{2}{3}[/tex]

Answer:

D) 4.55%

Step-by-step explanation:

Given:

Rented Income = $3000 per month

= $3000 * 12 = $36,000 annually

Less : - Annual expenses = $11700

Depreciation(3% OF 235000) = $7050

Tax, repairs and Insurance = 15430

Annual net income = $36,000 - ($11,700+$7,050+$15,430)

= $36,000 - $34,180

Annual net income = $1,820

To find annual yield, use the formula below:

Annual yield = (annual net income/down payment) * 100

Therefore, annual yield will be:

Annual yield [tex] = \frac{1,820}{40,000} * 100 [/tex]

= 0.0455 * 100

= 4.55%

Annual yield = 4.55%

Answer:

x = 25; both labeled angles are 65º

Step-by-step explanation:

To find the value of x, recall that the angles formed by two parallel lines on the same line are equal if they correspond to each other.

In the figure given above, we have two parallel line given. The angle formed by each parallel line is corresponding to the other. Therefore, both angles formed are equal.

Thus,

(3x - 10)° = (x + 40)°

Solve for x

3x - 10 = x + 40

Subtract x from both sides

3x - 10 - x = x + 40 - x

3x - x - 10 = x - x + 40

2x - 10 = 40

Add 10 to both sides

2x - 10 + 10 = 40 + 10

2x = 50

Divide both sides by 2

2x/2 = 50/2

x = 25

*Plug in the value of x to find the measure of each labelled angles:

(3x - 10)° = 3(25) - 10 = 75 - 10 = 65°

(x + 40)° = 25 + 40 = 65°

Answer:

lateral area =150 square feet

Step-by-step explanation:

lateral area =(perimieter of prism base) times the height of the prism

so, the perimeter of the base is 9 ft*2 + 6 ft*2 which equals 30 ft

then you multiply the perimeter of the base by the height of the prism

so, height of prism =5 ft, so 5 ft times 30 ft =150 feet

therefor, the lateral area of the prism = 150 feet squared

Answer:

let the number of calories from lunch be called L. As such, breakfast is then L + 128, and dinner is 2L - 400. We can then sum the three meals and equate it to the total caloric intake, the known value of 1932.

  So: 1932 = L + L + 128 + 2L - 400 = 4L - 272.

  Lunch = 551

Breakfast = 551 + 128 = 679

Dinner = 2*551 - 400 = 702

Answer:

1. The margin of error is of 66.96 square feet.

2. The 95% confidence interval estimate for the population mean using the Student's t-distribution is between 1433.04 square feet and 1566.96 square feet

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 22 - 1 = 21

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 21 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.08

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.08*\frac{151}{\sqrt{22}} = 66.96[/tex]

In which s is the standard deviation of the sample.

The margin of error is of 66.96 square feet.

The lower end of the interval is the sample mean subtracted by M. So it is 1500 - 66.96 = 1433.04 square feet

The upper end of the interval is the sample mean added to M. So it is 1500 + 314 = 1566.96 square feet

The 95% confidence interval estimate for the population mean using the Student's t-distribution is between 1433.04 square feet and 1566.96 square feet

Answer: 8.6602540378

Step-by-step explanation:

Based on pythagorean’s theorem we have:

[tex]\sqrt{14^{2}-11^{2} } =\sqrt{75}=8.66025[/tex]

Answer:

Probability is 1

Step-by-step explanation:

We are given;

mean;μ = $2,075

Standard deviation;σ = $300

n = 55

x' = $1,985

Now, we want to find x' to be at least $1,985 which is P(x' > $1,985).

The z-value is calculated from;

z = (x' - μ)/(√σ/n)

Plugging in the relevant values;

z = (1985 - 2075)/(√300/55)

z = -38.536

So, P(x' > $1,985) = P(z > -38.536)

This transforms to;

P(z < 38.536)

Probability from z distribution table is 1
