Question

mean of 10,12,18,13p and 17 is 15 ​

Answer 1

Step-by-step explanation:

We know that mean of a given observations is nothing but the sum of the individual observations divided by the total number of observations. ...

Mean= Sum of the individual observations / total number of observations

So in the question, we are given 5 observations 10 ,12, 18, 13p and 17 and they gave the mean to be 15

So, 15 = 10 + 12 + 18 + 13p + 17/5

75 = 57 + 13p

13p = 18

Therefore , p = 18/13

Answer 2

Answer:

10+12+18+13p + 17/5 = 15

57+ 13p = 75

13p = 75-57

13p = 18

p = 18/13
