Answer:

Option C

Step-by-step explanation:

We would have the find the diet that are not Acadia leaves. Since the giraffes eat 75 pounds per day, we can simply subtract the quantity of the Acadia leaves from the 75 to get the amount for the other leaves.

You can also use the equation given in the question to check your answer if you use Option C's equation.

Option C should be the correct answer.

Find the volume of the solid generated by revolving the region bounded by the lines and curves about the x-axis. y = x, y =1, x

liraira [26]

Answer:

The volume is: $V = \frac{\pi}{3}$ cubic units

Step-by-step explanation:

Volume of a solid:

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

$V = \pi \int_{a}^{b} (f(x))^2 dx$

y = x, y =1, x = 0

This means that the upper function is y = 1, and the lower function is y = x. So

$f(x) = (1 - x)$

The lower limit of integration is x = 0.

The upper limit is y = x when y = 1, so x = 1.

Then

$V = \pi \int_{a}^{b} (f(x))^2 dx$

$V = \pi \int_{0}^{1} (1-x)^2 dx$

$V = \pi \int_{0}^{1} (1-2x+x^2) dx$

$V = \pi (x-x^2+\frac{x^3}{3})|_{0}^{1} dx$

$V = \pi(1 - (1^2) + \frac{1^3}{3})$

$V = \frac{\pi}{3}$

The results of a national survey showed that on average, adults sleep 6.7 hours per night. Suppose that the standard deviation i

Roman55 [17]

Answer:

a) Atleast 75%

b) Atleast 88.9%

c) 95%

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 6.7

Standard Deviation, σ = 1.6

Chebyshev's Theorem:

Atleast $1 - \dfrac{1}{k^2}$ percent of data lies within k standard deviation of mean.

Empirical Rule:

Almost all the data lies within 3 standard deviation for a normal data.
Around 68% of data lies within 1 standard deviation of mean.
Around 95% of data lies within 2 standard deviation of mean.
Around 99.7% of data lies within 3 standard deviations o mean.

a) minimum percentage of individuals who sleep between 3.5 and 9.9 hours

$3.5 = \mu - 2\sigma = 6.7 - 2(1.6)\\9.9 = \mu + 2\sigma = 6.7 + 2(1.6)$

We have to find the percent of data lying within 2 standard deviation of mean.

Putting k = 2

$1 - \dfrac{1}{(2)^2} = 0.75 = 75\%$

Atleast 75% of of individuals who sleep between 3.5 and 9.9 hours.

b) minimum percentage of individuals who sleep between 2.7 and 10.7 hours

$2.7 = \mu - 3\sigma = 6.7 - 3(1.6)\\10.7 = \mu + 3\sigma = 6.7 + 3(1.6)$

We have to find the percent of data lying within 3 standard deviation of mean.

Putting k = 3

$1 - \dfrac{1}{(3)^2} = 0.889 = 88.9\%$

Atleast 88.9% of of individuals who sleep between 2.7 and 10.7 hours.

c) percentage of individuals who sleep between 3.5 and 9.9 hours per day.

Thus, we have to find the percentage of data lying within 2 standard deviation.

By empirical rule, around 95% of data lies within 2 standard deviation.

Thus, 95% of of individuals who sleep between 3.5 and 9.9 hours.

This is higher than the percentage obtained from Chebyshev's rule.
