Question

How do you determine what your grade average is based on the following grades?:

Answer 1

Answer:

Test's average-95

Homework's average-96.67

Step-by-step explanation:

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

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

The Tests' average is calculated as:

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

Hence, the Tests' average is 95

#The Homework's average is calculated as:

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

Hence, the Homework's average is 96.67
