Question 9(Multiple Choice Worth 1 points) (05.04 MC)

When the outliers are removed, how does the mean change?

The mean remains the same.
The mean decreases by 2.
The mean increases by 2.
There are no outliers.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

part a: 1.08

part b: 27.59

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
