The total number of students is 250 from the solution in the image.
Answer:
13.3
Step-by-step explanation:
There is an equation that helps
mean= (All of the numbers in the data added) divided by (the number of numbers in the data)
What that mean is:
1.) Add 20, 5, 7, 17, 16, and 15
2.) divided by 6 (because there is 6 numbers in the data)
3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)
which in this case it should be 13.33333...=13.3
Answer:
is it A?

I think it's A because no one has answered!
Answer: 3
Explanation:
2/3 divided by 2/9
2/3 times 9/2
= 3
If AB = BC then set up the equation 3x - 4 = 5x - 10
Subtract 3x.
-4 = 2x - 10
Add 10.
6 = 2x
Divide by 2.
3 = x
AB is 3x - 4 so
3(3) - 4
9 - 4
5.
AB = 5
If AB is not equal to BC then this is not solvable.
But if they are I am sure AB = 5.
Hope this helps
