(a) Contrast the shapes of the data sets displayed in the box-and-whisker plots in Question 1. Explain what the difference in the shapes means in context of the situation.

(b) Compare the spread of the data sets. Discuss both the overall spread and the spread within the

boxes.

(c) Use an appropriate measure of central tendency to compare the center of the data sets. Explain what

the difference in those measures means in context of the situation.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

greater than one

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
