For the set {1, 1, 2, 4, 5, 6, 7, 8, 10,} which would not be affected if another value of 10 was included?

question 6 options:

a)range

b)mean

c)median

d)mode

A) Range

Step-by-step explanation:

The original mean would be 4.889. But when you add another 10 to the set, the mean becomes 5.400.

The original mode would be 1, because there are two 1's and only one of every other number. But when adding another 10 the the original set, you end up with two 10's so now the mode is 1 and 10.

The median changes from 5 to 5.5

So the answer has to be range.

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
