Given a right cone with radius r and slant height s what does the formula pi rs represent
Neporo4naja [7]

Answer:

\pi rs represents the lateral surface area of the cone.

Step-by-step explanation:

Lateral surface area of cone(L) is given by:

L = \pi \cdot r \cdot l            .....[1]

where,

r is the radius of the cone

l is the slant height of the cone.

As per the statement:

A right cone with radius r and slant height s.

⇒l = s

Substitute in [1] we have;

L = \pi \cdot r \cdot s

Therefore, \pi rs represents the lateral surface area of the cone.

You observe a portfolio for five years and determine that its average annual return is 13% and the standard deviation of its ret
horrorfan [7]

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:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

The information provided is:

\hat p = 0.13\\\sqrt{\frac{\hat p(1-\hat p}{n}} =0.21

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

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

The 95% confidence interval for average annual return is:

CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\=0.13\pm 1.96\times0.21\\=0.13\pm 0.4116\\=(-0.2816, 0.5416)\\\approx(-28\%, 54\%)

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.
