Answer:
247.21
Step-by-step explanation:
equation for height : c= a2 + b2
4.82 + 9.32
≈10.46566
equation for surface area: A=5
/4tan(54°)a2+5a
/2h2+(atan(54°)
/2)2
5
/4·tan(54°)·72+5·7
/2·7.972+(7·tan(54°)
/2)2
≈247.21018
round to nearest hundredth: 247.21

Answer:
There is a 95% probability that the portfolio would not loose more than 30% of its value.
Step-by-step explanation:
The confidence interval for proportions (<em>p</em>) is:

The information provided is:

For 95% confidence level the critical value of <em>z</em> is:

The 95% confidence interval for average annual return is:

The lower limit of the 95% confidence interval is -28%.
This implies that the portfolio would not loose more than 28% of its value.
Thus, there is a 95% probability that the portfolio would not loose more than 30% of its value.
