Answer ASAP please! If you can explain your answer it would be the best

Answer 1

The mean(average) is 85.5
The median(middle) is 90
The range(difference between lowest and highest)is 35
The mode is 95, since it popped up 4 times

Answer 2

Answer:

mean = 85.5

median = 90

mode = 95

range = 35

Step-by-step explanation:

First arrange the data in ascending order:

60 75 75 90 90 95 95 95 95

Mean is the average number found by adding all of the numbers together and dividing by the number of terms in the set.

$= \frac{60 + 75 + 75 + 90 + 90 + 95 + 95 + 95 + 95}{9}$

$= \frac{770}{9}$

=85.5

Median is the middle number of the set: (9+1) ÷2 = 5th term.

60 75 75 90 90 95 95 95 95

therefore the median is 90

The mode is the number that is repeated more often than any other, so 95 is the mode.

The range = the largest value - the smallest value

= L-S = 95-50

= 35

Therefore the range is 35.
