Average cost is the ratio of total cost and the number of goods. Hence, for this problem:
Average cost= ![\frac{Total cost}{Number of candles}](https://tex.z-dn.net/?f=%20%5Cfrac%7BTotal%20cost%7D%7BNumber%20of%20candles%7D%20%20)
So, ![A(b)=\frac{c(b)}{b}](https://tex.z-dn.net/?f=%20A%28b%29%3D%5Cfrac%7Bc%28b%29%7D%7Bb%7D%20%20)
Where A(b)= average cost, c(b)= total cost and b= number of candles.
Since, c(b)=250+3b
So, the average cost is ![A(b)=\frac{250+3b}{b}](https://tex.z-dn.net/?f=%20A%28b%29%3D%5Cfrac%7B250%2B3b%7D%7Bb%7D%20)

The angle of depression is 35 degree in the right angle triangle if the angle BAC is 55 degree.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have shown a right-angle triangle in the picture.
In the right angle triangle, ABC
The angle BAC = 55 degree
Angle BAA' = 90 degree
In the figure, the angle of depression = CAA'
= BAA' - BAC
= 90 - 55
= 35 degree
Thus, the angle of depression is 35 degree in the right angle triangle if the angle BAC is 55 degree.

Answer:
the P value is 45.22%
Step-by-step explanation:
The computation of the P value is as follows;
Given that
standard deviation = 14.9
mean = 675
Reduction in diameter= 673.2
Based on the above information,
We have to applied the following formula i.e.
![Z = \frac{x - \bar x}{\sigma} \\\\= \frac{673.2 - 675}{14.9}\\\\= -0.1208](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7Bx%20-%20%5Cbar%20x%7D%7B%5Csigma%7D%20%5C%5C%5C%5C%3D%20%5Cfrac%7B673.2%20-%20675%7D%7B14.9%7D%5C%5C%5C%5C%3D%20-0.1208)
Now the P value for -0.1208 is 0.4522 i.e. 45.22%
Hence, the P value is 45.22%
