The writing is confusing, but as I understand it 21 is about 20% of 104 (21x100/104). The same prosentage of 500 equals 100,96 and I would round it to 101 (the answer of the first equasion x 500/100).

A bicycle company is designing women's bicycle frames. The frames can accommodate any woman taller than 54.5 inches. Given that
ladessa [460]

Using the normal distribution, it is found that 0.13% of American women CAN NOT use the bicycles designed by this company.

<h3>What is Normal Probability Distribution?</h3>

The z-score of a measure X of a normally distributed variable with mean  and standard deviation  is given by:

z=\dfrac{x-\mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

\mu = 65\ \ \sigma= 3.5

The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:

z=\dfrac{x-\mu}{\sigma}

z = \dfrac{54.5-65}{3.5}

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% of American women CAN NOT use the bicycles designed by this company.

Tim and Fred were able to restock the store in 7 hours together. It takes
Galina-37 [17]

Answer:

When 2 people work together the total time equals

Total Time = Time 1 * Time 2 / (Time 1 + Time 2)

Let's solve for Time 1 (which will be Tim's time.)

7 hours = Time 1 * 9 / (Time 1 + 9)

7 * Time 1 + 63 = Time 1 * 9

63 = 2 * Time 1

Time 1 = 30.5 Hours (Tim's Time)

Double Check

Total = 30.5 * 9 / (30.5 + 9)

Total = 274.5  / 39.5

Total = 7 Hours

Again, Tim's Time is 30.5 Hours
