Answer:
38.9 square inches.
Step-by-step explanation:
We are asked to find the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compared to a pair of 5 inch wipers operating together each having a central angle of 114 degrees.
We will use area of sector formula to solve our given problem as:
, where, r represents radius and theta represents central angle.
Let us find area of sector with central angle 140 degree and radius 3 inch.



Now, we will find area of sector with central angle 114 degree and radius 5 inch and multiply by 2 as:




Let us find difference of area as shown below:



Therefore, the difference in area covered is approximately 38.9 square inches.
Answer:
ITS C
Step-by-step explanation:
Because since it has a one time fee of 5, the graph has to start at 5, then you narrow it down to c or d, if you look at d then you can see that the graph isnt going up 2 dollars, so then the answer is c.
A null hypothesis illustrates that two variables in the hypothesis have no statistical significance.
The null hypothesis is: 
The regression equation is given as:

The variables are:
and 
The null hypothesis states that, there is no statistical significance between
and
.
This is represented as:

Hence, the null hypothesis is:
