To work it out:
(20200 + 14500 + 18800 + 9300 + 2200) divide by the number of regions, in this case 5.
The answer is 13000 which is A

Basically the mean is adding all the numbers divided by the amount of numbers you added. So in this case adding the data of the 5 regions divided by 5.

Hope to have helped :)

26. In a neighborhood donut shop, one type of donut has 570 calories, seven types of donuts have 600 calories, seven types of do
creativ13 [48]

we have

1 donut -----> 570 calories

7 donuts ----> 600 calories

7 donuts ----> 510 calories

4 donuts ----> 480 calories

3 donuts ----> 400 calories

so

total donuts=1+7+7+4+3=22 donuts

the means is equal to

mean=(1*700+7*600+7*510+4*480+3*300)/22

mean=11,460/22

<h2>mean=521 calories</h2>

Part 2

Find out the median

order the data set from less to greater

400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600

the median is the middle of the data set

400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600

<h2>the median is 510 calories</h2>

The image of (6, 9) under a dilation is (4, 6).
Ad libitum [116K]
For this case we have the following ordered pairs:
 (6, 9)
 (4, 6)
 The scale factor can be found in two different ways:
 k = 6/4 = 3/2 = 1.5&#10;&#10;k = 9/6 = 3/2 = 1.5
 Therefore, the scale factor is given by:
 k = 1.5&#10;
 Answer:
 
The scale factor of the dilation is 1.5

t= 2.25 secs

Step-by-step explanation:

Step 1 :

Equation for motion with uniform acceleration is v = u+ at

where v is the final velocity

          u is the initial velocity

          a is the acceleration due to gravity

          and t is the time

Step 2 :

Here , v = 0 because at the highest point final velocity is 0.

u = 72 feet/sec

a = -32 ft/sec^2

We need to find the time t.

Substituting in the equation we have,

0 = 72 -32 * t

=> 32 t = 72

=> t = 72/32 = 2.25 secs
