Question

the mean of 8 numbers is 12 five of the numbers are 6 8 5 10 qnd 28the remaining three numbers are each equal to k

Answer 1

Answer:

Step-by-step explanation:

mean  =  Total  / number of numbers

  OR

M = T / N

Note that if you know the mean and how many numbers there are, you can find the total.

T  =  M  ×  N ⇒ 8 × 12 = 96

out of 8 numbers, five numbers are 6,8,5,10,28.

sum of 28+10+8+6+5 = 57

so the mean of other 3 numbers are = 57 ÷ 3 = 19
