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>

Find the equation of the line

Gre4nikov [31]

Answer:

y= - 1/6x -1

Step-by-step explanation:

Given:

y= 6x -2

and point (6, -2)

Perpendicular line has slope of reciprocal opposite to the given: - 1/6, so the equation:

y= -1/6x + b

Finding b using the intersected point:

-2= -1/6*6 +b
b= -2 +1= -1

So the equation is:

y= - 1/6x -1
