Question

If the first 5 students expect to get the Final Average of 95, what would their Final Tests need to be?? Please let me know how to get the final scores.

Answer 1

Answer:

475

Explanation:

An average value is the sum of all initial values divided by the number of values used.

i.e Av = $\frac{sum of values}{number of values}$

Since the 5 students are expecting final average of 95, then their final test score can be determined by;

number of values used = 5, and the average = 95

So that;

95 = $\frac{sum of values}{5}$

⇒ sum of values = 95 × 5

                           = 475

sum of values = 475

The first 5 students' final test score = sum of values = 475.

Their final test score need to be 475.
