Answer 1

Answer:

Given the mean of 10 ,12 , 18 , 13 , P and 17 is 15

Mean =  

n

Σx

​

 

15=  

6

10+12+18+13+P+17

​

 

90=70+P

P=90−70=20cm

Step-by-step explanation:

Answer 2

Answer:

ஃ p = 23

Step-by-step explanation:

$\sf Mean = \frac{Sum \: of \: all \: observation}{No. \: of \: observation}$

$\sf = \frac{10 + 12 + 13 + p + 17}{5} = 15$

$\sf = \frac{52 + p}{5} = 15$

$\sf = 52 + p = 15 \times 5$

$\sf = 52 + p = 75$

$\sf = p = 75 - 52 = 23$
