A roll of 100 pennies is in the shape of a right cylinder. Each penny has a diameter of 0.75 inches and a thickness of 0.04 inch
zalisa [80]

Answer:

  • (B) π(0.75/2)²(4)

Step-by-step explanation:

<u>The volume formula:</u>

  • V = πr²h

<u>Given:</u>

  • d = 0.75 in ⇒ r = d/2 = 0.75/2 in
  • h = 0.04 in

<u>The volume of each penny:</u>

  • V = π(0.75/2)²(0.04)

<u>The volume of 100 pennies:</u>

  • V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)

Correct choice is B

Answer:

The standard deviation of the load distribution is of 5102.041 pounds.

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 = 20000

Also, the probability that the load is between 10,000 and 30,000 pounds is 0.95.

10,000 pounds and 30,000 pounds are equidistant from the mean. Due to this, and the probability of 0.95 of having a value in this range, 10000 is the (100-95)/2 = 2.5th percentile and 30000 is the (100+95)/2 = 97.5th percentile. Applying one of them, we find the standard deviation.

30,000 is the 97.5th percentile:

This means that when X = 30000, Z has a pvalue of 0.975. So when X = 30000, Z = 1.96. Then

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

1.96 = \frac{30000 - 20000}{\sigma}

1.96\sigma = 10000

\sigma = \frac{10000}{1.96}

\sigma = 5102.041

The standard deviation of the load distribution is of 5102.041 pounds.
