Raul is practicing for baseball tryouts he wants to find how far he can hit a baseball he hits the ball 10 times and measures th
wel

Answer:

See Explanation

Step-by-step explanation:

Given

n = 10 --- Number of tryouts

Required

Determine the average distance

<em>This question has missing details, as the distance he hits the ball in each tryout is not given. However, I'll give a general explanation.</em>

<em></em>

The mean is calculated as:

\bar x = \frac{\sum x}{n}

\sum x means the sum of the distance in each tryout.

Assume that the distance in the 10 tryouts are: 6, 8, 5, 9, 4, 5, 8, 7, 7, 6.

So, the mean is:

\bar x = \frac{6+ 8+ 5+ 9+ 4+ 5+ 8+ 7+ 7+ 6}{10}

\bar x = \frac{65}{10}

\bar x = 6.5}

<em>So, the average distance is 6.5</em>
