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:
[tex]\bar X=\frac{1}{n}\sum{x_i}, n=number \ of \ values.[/tex]
The Tests' average is calculated as:
[tex]\bar X_t=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(98+92+95)\\\\=\frac{1}{3}\times 285\\\\=95[/tex]
Hence, the Tests' average is 95
#The Homework's average is calculated as:
[tex]\bar X_h=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(93+97+100)\\\\=\frac{1}{3}\times 290\\\\=96.67[/tex]
Hence, the Homework's average is 96.67
