Question

THE MEAN OF 6 , 7, x , 14 AND y IS 8 THEN x + y =



11

13

10

8

​

Answer 1

Answer:

Mean is Sum of the observations/total no of obs.

So, as per question,

(6+7+x+14+y)/5 = 8

Then => 6+7+x+14+y = 40

=> x+y = 40-6-7-14

=> x+y = 13.

Hope it helps.

Answer 2

Answer:

13

Step-by-step explanation:

let the mean be m.

then m=6+7+x+14+y/5=8 (given)

then 27+x+y=8*5

then x+y=40-27=13.

this is the answer .

we solved it using the mean of ungrouped data.

sum of observations upon number of observations
