Answer:

15 people

Step-by-step explanation:

Ruby surveyed a sample of

4 + 3 + 1 = 8 people

Out of which, 3 preferred pepperoni pizza.

So that's 3 out of 8 people preferring pepperoni pizza (or 3/8 = 37.5%]

Now, if we make this into 40 people, the prediction of how many would like pepperoni pizza would be same ratio. So:

3/8 * 40 = 15 people

Our prediction would be 15 people

Find the average rate of change of the function between the given values of x. y = 9+ 5x + 0.5x2 between x = 2 and x = 4.
svet-max [94.6K]

Answer:

The average rate of change is 8.

Step-by-step explanation:

The formula to calculate the average rate of change of a function F(x) is:

\frac{F(b)-F(a)}{b-a}

In this case, F(x) = 0.5x^{2} +5x+9

a=2 and b=4

You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.

In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:

F(b) = (0.5)4^{2} + 5(4) +9= 37

F(a) = (0.5)2^{2} + 5(2)+9=21

\frac{F(b)-F(a)}{b-a} = \frac{37-21}{4-2}=\frac{16}{2} = 8

The answer is 8.

Line $\ell_1$ is horizontal and passes through $(1,1)$. Line $\ell_2$ is vertical and passes through $(2,2)$. Find the point of
borishaifa [10]

Answer:

(2,1)

Step by step explanation:      

Please find the attachment.

We have been given that line l_1 is horizontal and passes through point (1,1). Line l_2 is vertical and passes through point (2,2). We are asked to find point of intersection of line l_1 and line l_2.  

Line l_1 is a horizontal line so y-coordinate will be 1 for any value of x. Line l_2 is a vertical line, so x-coordinate will be 2 for any value of y.

Therefore, intersection point of both lines will include x-coordinate of line l_2 and y-coordinate of line l_1 that is (2,1).
