Question

The average length of 5 sticks is 15 cm.What is the total length of the 5 sticks?

Answer 1

Answer:

The total length of the 5 sticks is 75.

Step-by-step explanation:

The formula to compute average is:

$\bar x=\frac{1}{n}\sum x$

Given:

$\bar x=15\\n=5$

Compute the sum of the lengths of all 5 sticks as follows:

$\bar x=\frac{1}{n}\sum x\\15=\frac{1}{5}\sum x\\\sum x=15\times5\\=75$

Thus, the total length of the 5 sticks is 75.

Answer 2

Answer:

75

Step-by-step explanation:

just multiply 5 from 15
