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 classes b)the range is the same for both classes c)the mean is the same for both classes d)the median is the same for both classes

The mean is the same for both classes

Step-by-step explanation:

Class A scores of 10 students: 100,100,100,90,95,85,92,98,92,88

Arrange the data in ascending order

85,88,90,92,92,95,98,100,100,100

Mode = 100 since it occurred more times.

Range = Maximum - Minimum = 100-85 = 15

Mean =

Mean =

Mean = 94

Median = mid value

n = 10 (even)

So, median =

                  =

                 =

                 =

                 =

Median = 93.5

Class B scores of 10 students : 100,100,98,95,95,96,95,92,81,88

Arrange the data in ascending order

81,88,92,95,95,95,96,98,100,100

Mode = 95 since it occurred more times.

Range = Maximum - Minimum = 100-81 = 19

Mean =

Mean =

Mean = 94

Median = mid value

n = 10 (even)

So, median =

                  =

                 =

                 =

                 =

Median = 95

So, The mean is the same for both classes is same i.e. 94.

Hence Option C is correct.

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
