0.000063
Step-by-step explanation:
Number of Respondents, n=1400
Probability that they would rate their financial shape as excellent = 0.09
Number of Those who would rate their financial shape as excellent
=0.09 X 1400
=126
Therefore:
The probability that 4 people chosen at random would rate their financial shape as excellent
![=\dfrac{^{126}C_4 \times ^{1400-126}C_0}{^{1400}C_4} \\=\dfrac{^{126}C_4 \times ^{1274}C_0}{^{1400}C_4}\\=0.000063 $(correct to 6 decimal places)](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5E%7B126%7DC_4%20%5Ctimes%20%5E%7B1400-126%7DC_0%7D%7B%5E%7B1400%7DC_4%7D%20%5C%5C%3D%5Cdfrac%7B%5E%7B126%7DC_4%20%5Ctimes%20%5E%7B1274%7DC_0%7D%7B%5E%7B1400%7DC_4%7D%5C%5C%3D0.000063%20%24%28correct%20to%206%20decimal%20places%29)

Answer:
<em>The tower is 48 ft tall.</em>
Step-by-step explanation:
Refer to the figure attached.
Triangle ACD is similar to triangle BCE.
This means the proportion to some sides is the same, for example:
![\displaystyle \frac{CE}{CD}=\frac{BE}{H}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7BCE%7D%7BCD%7D%3D%5Cfrac%7BBE%7D%7BH%7D)
Substituting the values:
![\displaystyle \frac{8}{64}=\frac{6}{H}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B8%7D%7B64%7D%3D%5Cfrac%7B6%7D%7BH%7D)
Multiplying by 64H:
![8H=64*6](https://tex.z-dn.net/?f=8H%3D64%2A6)
Dividing by 8:
![H=64*6/8=48](https://tex.z-dn.net/?f=H%3D64%2A6%2F8%3D48)
The tower is 48 ft tall.
