Students in two classes took a mathematics achievement test. The box plots display the data.
box plot class 1 and class 2

Which of the following is true?

1)Half of the scores in Class 1 are less than one-fourth of the scores in Class 2.

2)At least half of the scores in Class 2 are greater than all the scores in Class 1.

3)The interquartile range (IQR) of Class 2 is less than the IQR of Class 1.

4)The range of Class 1 is greater than the range of Class 2.

Option 1 is correct

Step-by-step explanation:

2)At least half of the scores in Class 2 are greater than all the scores in Class 1.

Step-by-step explanation:

Since the median line for class 3 is ahead of the entire distribution of class 1, we can claim that atleast 50% of scores area greater in class 2

true

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
