We have this equation:

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:


Then, dividing the equation by 2:

Finally, let's order this equation:
Dont know a but b is
75=100-2p
75 minus 100 = -25=-2p
-25/-2= p
p=$12.50
Answer:
78
Step-by-step explanation:
Mode = number that appears most in a set of numbers
The number that appears the most in this set is 78. So, the mode is 78. Hope it helps!
Answer:
60
Step-by-step explanation:
Area = ((a+b)/2)h=((7+13)/2)*6=60
Answer:
The homework grade, to the nearest integer, for a student with a test grade of 68 is 69.
Step-by-step explanation:
The general form of the linear regression equation is:

Here,
<em>y</em> = dependent variable = test grade
<em>x</em> = independent variable = homework grade
<em>a</em> = intercept
<em>b</em> = slope
Compute the value of <em>a</em> and <em>b</em> as follows:

The linear regression equation that represents the set of data is:

Compute the value of <em>x</em> for <em>y</em> = 68 as follows:


Thus, the homework grade, to the nearest integer, for a student with a test grade of 68 is 69.
