Question

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

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

$Mean=\frac{sumofallnumber}{Tota\mathrm{l}number}$

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

$\begin{array}{l}Mean=\frac{sumofallnumber}{Tota\mathrm{l}number}\\ Mean=\frac{464}{5}\\ Mean=92.8\end{array}$
