Answer:
C. 15.9 m
Step-by-step explanation:
Let x be the height of the telephone pole,
Since, the length of the shadow of pole is 34 m,
So, the ratio of the height of the pole and its shadow =
,
Also, the statue is of 36 cm tall casts a shadow 77 cm long,
Thus, the ratio of the height of pole = ![\frac{36}{77}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B77%7D)
At the same time,
The ratio of height with shadow is same for all objects.
![\frac{x}{34}=\frac{36}{77}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B34%7D%3D%5Cfrac%7B36%7D%7B77%7D)
![x=\frac{34\times 36}{77}=\frac{1224}{77}=15.8961038961\approx 15.9](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B34%5Ctimes%2036%7D%7B77%7D%3D%5Cfrac%7B1224%7D%7B77%7D%3D15.8961038961%5Capprox%2015.9)
Hence, the height of the telephone pole is 15.9 m.
Option 'C' is correct.
- Net income=400
- Expenses=380
Amount earned per week=400-380=$20
Price of one shoe=70$

We have been given that adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketball player is 79 inches tall.
We need to find the area of normal curve above the raw score 79.
First of all let us find the z-score corresponding to our given raw score.
, where,
,
,
,
.
Upon substituting our given values in z-score formula we will get,
Now we will find the P(z>3) using formula:
Using normal distribution table we will get,
Let us convert our answer into percentage by multiplying 0.00135 by 100.
Therefore, approximately 0.135% of the adult male population is taller than the average basketball player and option A is the correct choice.
