In general, an inverse variation relation has the form shown below

It is given that x=16, then y=5/4; thus,

Therefore, the equation is y=20/x

2) Set x=4 in the equation above; then

When x=4, y=5.

Given:

A graph

To determine the Mean, Median, and Mode based on the given graph, we first get the data set as shown below:

2,5,5,5,5,6,9,11,12,13,14,15,18,20

Next, we find the Mean by getting the average:

Then, we get the Median by getting the average of the two middle values since there is an even number of data values:

Now, we get the Mode by finding the number that appears most frequently. Hence, the Mode is 5.

Therefore, the answer is:

Mean:10, Median:10, Mode:5

Find the inverse of:

The variable x can take any real value and the function f(x) exists. This means

the domain of f(x) is (-∞, +∞).

Now find the inverse function.

Swapping letters, we get the inverse function:

For each value of x, we get two values of y, thus this is not a function.

The domain of the inverse is restricted to values of x that make the square root exist, thus the domain is x ≥ 0, or [0, +∞)

The range of the inverse is the domain of the original function, that is, (-∞, +∞)

Function: No

Domain: [0, +∞)

Range: (-∞, +∞)

The choice to select is shown below.

Considering the given table, it is found that:

a. The exponential regression equation is: P(t) = 2408.80(1.059)^t.

b. The yearly percent increase is of 5.9%.

c. P(13) = 5075.

d. The population of the town after 13 years is of 5075.

The exponential regression equation is found inserting the points into a calculator.

The points are given as follows:

(0, 2400), (3, 2801.27), (7, 3608.71), (12, 4974.15), (14, 5426.17), (19, 6898.37).

Using a calculator, the function is:

2408.80(1.059)^t.

The yearly percent increase rate is calculated as follows:

1 + r = 1.059

r = 1.059 - 1

r = 0.059

r = 5.9%.

Then in 13 years, the population will be given as follows:

P(13) = 2408.80(1.059)^13 = 5075.

Therefore, the area of the shape is 48 square inches.

Part B

The perimeter of a shape is the sum of all the outer sides enclosing the shape

From the above shape, we add all four sides together

Consequently, we can get the perimeter using formula method as well

Therefore, the perimeter of the shape is 32 inches.

Part C

ANSWER

z = 1.88

EXPLANATION

We have to find z such that the area under the normal curve to the right of that value is 0.03,

This is the same as finding z such that the area to the left of that value is 1 minus 0.03,

These are the values that z-score tables show. So, we have to find a z-score where the value in the table is 0.97,

The z-score whose area to its left is closest to 0.97 is z = 1.88.

Hence, for z = 1.88, the area under the curve to its right is 0.03.

Answer:

y = 1/10x + 9/10

Step-by-step explanation:

Find slope intercept form: –2x = –20y + 18

slope intercept form: y = mx + b

_______________________________

–2x = –20y + 18

add 20y to both sides:

–2x + 20y = –20y + 18 + 20y

–2x + 20y = 18

add 2x to both sides:

–2x + 20y + 2x = 18 + 2x

20y = 18 + 2x

divide all terms by 20:

20y/20 = 18/20 + 2x/20

y = 9/10 + 1/10x

reorder terms for slope intercept form:

y = 1/10x + 9/10

Answer:

[tex]y=\dfrac{1}{10}x+\dfrac{9}{10}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Given equation:

[tex]-2x=-20y+18[/tex]

To write the given equation in slope-intercept form, make y the subject.

Add 20y to both sides:

[tex]\implies 20y-2x=-20y+18+20y[/tex]

[tex]\implies 20y-2x=18[/tex]

Add 2x to both sides:

[tex]\implies 20y-2x+2x=2x+18[/tex]

[tex]\implies 20y=2x+18[/tex]

Divide both sides by 20:

[tex]\implies \dfrac{20y}{20}=\dfrac{2x+18}{20}[/tex]

[tex]\implies \dfrac{20y}{20}=\dfrac{2x}{20}+\dfrac{18}{20}[/tex]

[tex]\implies y=\dfrac{1}{10}x+\dfrac{9}{10}[/tex]

Therefore, the given equation in slope-intercept form is:

[tex]\boxed{y=\dfrac{1}{10}x+\dfrac{9}{10}}[/tex]

The volume of the cone is 45.28 cubic inches.

The amount of sand inside the cone is measured by its volume.

Based on the numbers for the radius and height, the cone's volume is 45.28 cubic inches.

The volume of a cone is the measure of how much space a cone takes up. Cone height and base radius both affect how much space the cone takes up.

The volume of the cone is given by V = [tex]\frac{1}{3}\pi r^{2} h[/tex]

The value of the radius is r = [tex]3\frac{1}{23} = \frac{70}{23}[/tex]

The value of Height is h = [tex]3\frac{5}{3} = \frac{14}{3}[/tex]

So, the Volume of the cone =[tex]V =\frac{1}{3}\pi r^{2} h[/tex]

[tex]V =\frac{1}{3}\pi r^{2} h\\\\V = \frac{1}{3}\pi (\frac{70}{23}) ^{2} \frac{14}{3} \\\\V = 45.28[/tex]

Answer:

22 feet

Explanation:

The area of a triangle can be calculated using the following equation:

Where b is the base and h is the height.

We know that the area is 330 square feet and the base is 30 ft, so we can replace these values to get:

Now, we can solve the equation for h. First, multiply both sides by 2:

Then, divide both sides by 30:

Therefore, the height of the triangle is 22 feet.

A graph of the proportional relationship is given by: D. graph with x axis labeled time seconds and y axis labeled sit ups, with a line from 0 comma 0 going through 90 comma 30.

A graph can be defined as a type of chart that's commonly used for the graphical representation of data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate.

Mathematically, a proportional relationship can be modeled by the following linear equation:

y = kx

Where:

Furthermore, the graph of any proportional relationship is characterized by a straight line with data points passing through the origin (0, 0) because as the values on the x-coordinate (x-axis) decreases or increases, the values on the y-coordinate (y-axis) decreases or increases simultaneously.

In this context, we can reasonably infer and logically deduce that the relationship between the values on the x-coordinate (x-axis) and y-coordinate (y-axis) of this graph is proportional and given by this equation:
