Answer 1

The average marks in Mathematics is 20.

Step-by-step explanation:

The average of a set of numbers is computed using the formula:

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

The set of values is:

S = {25, 22, 18, 19, 16}

Compute the average marks in Mathematics as follows:

$\bar x=\frac{1}{5}[25+22+18+19+16]=\frac{100}{5}=20$
