Question

The mean height of 12 men is 1.70 m, and the mean height of 8 women is 1.60 m. Find:the total height of the 12 men

Answer 1

20.4 m

Explanation:

mean is calculated as

mean =
`(total)/(count)`

given mean height of 12 men is 1.70 m , then

`(total)/(12)` = 1.7 ( multiply both sides by 12 to clear the fraction )

total height = 12 × 1.7 = 20.4 m
