What is the mean? Round to the nearest tenth if needed. Value 1 2 3 4 5
Frequency 7 1 3 2 2

Shown work is needed.

i think this is it

the answer would be 3

Step-by-step explanation:

It says something like this: Multiply each value by the frequency of that value:  1*7, 2*1, etc. I'll let you write down the rest.

Divide by the sum of the frequencies, 7 + 1

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
