The top ten scores on a quiz in two classes are listed below. class a: 100, 100, 100, 90, 95, 85, 92, 98, 92, 88 class b: 100, 100, 98, 95, 95, 96, 95, 92, 81, 88 which statement is true concerning the data? a) the mode is the same for both classesb) the range is the same for both classesc) the mean is the same for both classesd) the median is the same for both classes

C) The mean is the same for both classes.

Step-by-step explanation:

We have been given the top ten scores on a quiz in two classes. We are asked to choose the correct statement about the given data.

Class A: 100, 100, 100, 90, 95, 85, 92, 98, 92, 88

Class B: 100, 100, 98, 95, 95, 96, 95, 92, 81, 88

Let us see our given choices one by one.

A) The mode is the same for both classes.

We can see that mode for class A is 100 and mode for class B is 95. Since mode for both classes is different, therefore, statement A is false.

B) The range is the same for both classes.

Since range for both classes is different, therefore, statement B is false as well.

C) The mean is the same for both classes.

Since mean for both classes is same, therefore, statement C is true.

D) The median is the same for both classes.

Let us arrange both data sets in ascending order.

Class A: 85, 88, 90, 92, 92, 95, 98, 100, 100, 100.

Class B:  81, 88, 92, 95, 95, 95, 98, 96, 100, 100.

Since the median for both classes is different, therefore, statement D is false.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

mean, 40.6
