Question

If the mean of 5, 7, x ,10 ,5 and 7 is 7, then x = __________.

Answer 1

Answer:

The value of x=8

Step-by-step explanation:

because the given observations are=5,7,10,5,7,x

number of observations=6

arithmetic mean formula= sum of all observations/number of observations

$5+7+x+10+5+7 \div 6 = 7 \\ 34 + x \div 6 = 7 \\ 34 + x = 7 \times 6 \\ 34 + x = 42 \\ x = 42 - 34 \\ x = 8$

so the mean is 8
