Question

The mean of 8,p,14,17 is 12 Find the valu of p​

Answer 1

Given:

• Observations are 8,p,14,17
• Mean of Observations is 12

To Find:

• Value of p

Solution:

As, $\bold{࿇\; Arithmetic\;Mean = \frac{Sum\;of\; Observations}{Number\;of\; Observations}}$

Number of Observations = 4

Sum of Observations = 8+p+14+17 → 39+p

$→\;{\sf{12 = \frac{39+p}{4}}}$

$→\;{\sf{12×4 = 39+p}}$

$→\;{\sf{48-39 = p}}$

$→\;{\sf{p = 9}}$

AnSweR:

Value of p ◕➜ $\Large{\red{\mathfrak{9}}}$
