Question

if the mean of the following data is 6 find the value of p if x=2 y=3, x=4 y=2, x=6 y=3, x=10 y=1, x=p+5 y=2.​

Answer 1

Answer:

this the answer

Step-by-step explanation:

 2 3 6 4 2 8 6 3 18 10 1 10

N=∑fi=11∑fixi=2(p+5) 

We have, N=∑fi=11,∑fixi=2p+52

∴ Mean = N∑fixi=6112p+52⇒66=2p+52⇒2p=14⇒p=7
