Answer:

k = 40

Step-by-step explanation:

Given

The attached graph

Required

Calculate the constant of proportionality.

Represent the required constant with k.

Such that:

k = \dfrac{y}{x}

Pick any two corresponding values of x and y

(x,y) = (1,40)

This means that:

x = 1\ and\ y = 40

k = \dfrac{y}{x} becomes

k = \frac{40}{1}

k = 40

What is the mean of the data set? {96, 84, 92, 96, 100} Enter your answer in the box. Round to the nearest tenth.
vodomira [7]
In order to calculate the mean (average) you add up all the numbers and divide the total by how many numbers there are.

The sum of the data set is 468.

There are 5 numbers in the set.

468 divided by 5 is 93.6.

The answer is already to the nearest tenth, so the mean is 93.6.
