On three examinations, you have grades of 85, 78, and 84. There is still a final examination, which counts as one grade In order

kirill [66]

Answer:

The average of the provided grades are 86.75

Step-by-step explanation:

Consider the provided information.

On three examinations, you have grades of 85, 78, and 84. In order to get an A your average must be at least 90.

In the last exam you get 100 marks now calculate the average by using the formula:

$\frac{\text{Sum of observations}}{\text{Number of observations}}$

$\frac{85+78+84+100}{5}$

$\frac{347}{5}$

$86.75$

86.75 is less than 90 so you will not get A.

The average of the provided grades are 86.75
