Answer:

Test's average-95

Homework's average-96.67

Explanation:

Average is mathematically defined as the sum of the values divided by the total number of values and is expressed as:

$\bar X=(1)/(n)\sum{x_i}, n=number \ of \ values.$

The Tests' average is calculated as:

$\bar X_t=(1)/(n)\sum{x_i}\\\\=(1)/(3)(98+92+95)\\\\=(1)/(3)* 285\\\\=95$

Hence, the Tests' average is 95

#The Homework's average is calculated as:

$\bar X_h=(1)/(n)\sum{x_i}\\\\=(1)/(3)(93+97+100)\\\\=(1)/(3)* 290\\\\=96.67$

Hence, the Homework's average is 96.67
