If the mean of 25, 28, a, 30 and 32 is 27, then find the value of a.

Sagot :

Answer:

a = 20

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

          = [tex]\frac{25+28+a+30+32}{5}[/tex]  = [tex]\frac{115+a}{5}[/tex]

Then

[tex]\frac{115+a}{5}[/tex] = 27 ( multiply both sides by 5 to clear the fraction )

115 + a = 135 ( subtract 115 from both sides )

a = 20
