The box plot shows the algebra scores of students in class A and class B. The median score of class A is _.

The interquartile range of class B is _.

The difference of the medians of class A and class B is
the interquartile range of either data set.

The difference of the medians of class A and class B is between  the interquartile range of either data set.

Step-by-step explanation:

Given

The attached box plots

To answer this, see attached image for how to read a box plot

With reference to the attached image of how to read the box plot;

Solving (a): The median of class A

Solving (b): IQR of class B

IQR is calculated as:

From the box plot of class B, we have:

So, we have:

Solving (c):

IQR of class A is calculated as:

From the box plot of class A, we have:

So, we have:

The difference (d) between the medians is:

From to , we have: 8, 9, 10

i.e. IQR(B), d, IQR(A)

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
