Which of the following is likely to have the
greatest variability?
A. The cost of a piece of candy from a vending
machine
B. The height of all the students at West Middle
School
The age of all the students in the sixth grade
D. The number of days in a month

B. The height of all the students at West Middle school

Step-by-step explanation:

The greatest variability is a large spectrum of possibilities.

The costs of candy from a vending machine are all going to be about the same price because they are all candy, so that doesn't vary much.

The age of all the students in the sixth grade is going to be about the same because they are in the same grade.

The number of days in a month is usually 31 or 30, so that also does not vary much.

This means that it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
