A softball player got a hit in 20 of her last 50 times at bat. What is the experimental probability
1 answer:
Option B
The experimental probability that she will get a hit in her next at bat is 40 %
<h3><u>Solution:</u></h3>A softball player got a hit in 20 of her last 50 times at bat
To find: Experimental probability
<em><u>The experimental probability is given as:</u></em>
From given,
Number of times the event occurs = 20
Number of trials = 50
Therefore,
In percentage,
Thus the experimental probability that she will get a hit in her next at bat is 40 %

Answer:
Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line is
Step-by-step explanation:
Given:
To Find:
Equation of line passing through ( 16, -7) and is perpendicular to the line
Solution:
...........Given
Comparing with,
Where m =slope
We get
We know that for Perpendicular lines have product slopes = -1.
Substituting m1 we get m2 as
Therefore the slope of the required line passing through (16 , -7) will have the slope,
Now the equation of line in slope point form given by
Substituting the point (16 , -7) and slope m2 we will get the required equation of the line,
Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line is
The equation to show the depreciation at the end of x years is
Data;
- cost of machine = 1500
- annual depreciation value = x
This is an equation written to represent a word problem into mathematical statement and this is easier to solve.
To write a linear depreciation model for this machine would be
For number of years, the cost of the machine would become
This is properly written as
where x represents the number of years.
For example, after 5 years, the value of the machine would become
The value of the machine would be $500 at the end of the fifth year.
From the above, the equation to show the depreciation at the end of x years is f(x) = 1500 - 200x
