Step-by-step explanation:

$= \frac{14\pi}{6}$

$= \frac{ \cancel{14}\pi}{ \cancel6}$

$= \frac{7\pi}{3}$

$= \frac{6\pi + \pi}{3}$

$= \frac{6\pi}{3} + \frac{\pi}{3}$

$= 2\pi + \frac{\pi}{3}$

$= 0 + \frac{\pi}{3}$

$= \frac{\pi}{3} \: \text{where} \: \frac{\pi}{3} < 2\pi$

The answer is B.

I got 8/10 or 80% because if you add up all sandwichs together, you get 50, then you add up ham and tuna sandwichs and get 40 so 40/50 would be 80/100 to make it a percent or fraction.. hopefully this makes sense and i helped:) i wish i could just send the work to you so it could make more sense lol

Answer:

r²h(pie)+r³ over 3

Step-by-step explanation:

Call the radius r and the height of the cone h. The formula for the volume of a cone is r^2*h*pi/3, and the formula for the volume of a sphere is 4r^3/3, so half of a sphere has volume 2r^3/3. Adding these, our answer is: ^^

The daily dinner bills in a local restaurant are normally distributed with a mean of $28 and a standard deviation of $6. What ar

Degger [83]

Answer:

The minimum value of the bill that is greater than 95% of the bills is $37.87.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 28, \sigma = 6$
