Question

if the mean of 6 7 p 8 q is 9 then find the relation in p and q

Answer 1

Answer:

p+q = 24

Step-by-step explanation:

mean = sum of data points

number of data points

here,

sum of data points = 6+7+p+8+q

= 21+p+q

number of data points = 5

therefore,

9 = 21+p+q

5

9×5 = 21+p+q

45 = 21+p+q

45-21 = p+q

24 = p+q

thus the relation between p and q is that the sum of p and q is equal to 24
