Chapter 3: Q.12 (page 164)

Calculate the mean of your scores if you had five math tests this semester. Your score were $89, 97, 93, 86,$ and $99$ .

Short Answer

Expert verified

The mean of the scores are $92.8$ .

Step by step solution

Step 1. Apply the concept of Mean value

In this type of question, use the concept of mean value that is

$M e a n = \frac{s u m o f a l l n u m b e r}{T o t a l n u m b e r}$

Step 2. Finding the mean value by explaining the question

Since,

The scores of the maths in different semesters are $89, 97, 93, 86 & 99$ .

The sum of all the values of the scores are $89 + 97 + 93 + 86 + 99 = 464$

Total number of mean = $5$

Step 3. Calculating the mean

Now, the mean score is

$\begin{array}{l} M e a n = \frac{s u m o f a l l n u m b e r}{T o t a l n u m b e r} \\ M e a n = \frac{464}{5} \\ M e a n = 92.8 \end{array}$
