i think b

Answer 3

no

Answer 4

wait

Answer 5

dont guess

Answer 6

not a fo shure

Answer 7

give a legit answer and explain why you think it is that answer

Answer 8

60 68 68 76 *80 84* 90 90 90 92 94 100

Median becomes 82 it was originally 90
Average becomes 82.666666666667

So either B or C
Idk

Answer 9

76, 100, 94, 90, 68, 90, 80, 92, 84
first lets sort this list
68, 76, 80, 84, 90, 90, 92, 94, 100

that makes the median 90, now lets add the other numbers,

60, 68, 68, 76, 80, 84, 90, 90, 92, 94, 100

that makes the median 84.

now lets calculate the means of both
(68+76+80+84+90+90+92+94+100)/9=86

(60+68+68+76+80+84+90+90+92+94+100)/11=82

Answer 10

so both numbers went down.

Answer 11

and they also got closer together.

Answer 12

so C: The mean and median get closer together.
