PLEASE! What is the mean and MAD of the dot plot? Round The mad to the nearest hundreds

Mode: 5,7

Median: 6

Range: 13 - 2 = 11

IQR (interquartile Range): 7 - 5 = 2

Mean: 6

M.A.D (Mean Absolute Deviation): 1.73

( how I found the mean )

2 x 1 = 2

3 x 1 = 3

4 x 1 = 4

4 x 5  = 20

6 x 2 = 12

4 x 7 = 28

8 x 1 = 8

13 x 1 = 13

2 + 3 + 4 + 20 + 12 + 28 + 8 + 13 = 90/15 = 6!

mean = 6!

(finding the M.A.D mean absolute deviation)

6 - 2 = 4

6 - 3 = 3

6 - 4 = 2

6 - 5 = 1

6 - 5 = 1

6 - 5 = 1

6 - 5 = 1

6 - 6 = 0

6 - 6 = 0

6 - 7 = 1

6 - 7 = 1

6 - 7 = 1

6 - 7 = 1

6 - 8 = 2

6 - 13 = 7

1 x 4 = 4

1 x 4 = 4

4 + 3 + 2 + 4 + 4 + 2 + 7 = 26/15 = 1.73

so the answer to your question should be 1.73!

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

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

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

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

∴there are 88 seats in 12 rows.
