Answer:

  5.5 hours

Step-by-step explanation:

The presumption in these cases is that the rate of doing work is proportional to the number of machines. So, 4 times as many machines can do the work 4 times as fast. That is, the same job can be completed in 1/4 the time:

  (22 h)(1/4) = 22/4 h = 5.5 h

It would take 5.5 hours to fill the order.

Olve. Do your work on a separate she
Mazyrski [523]

Answer:

Step-by-step explanation:

2 coins are 0.25 = 50 cents. That leaves 92-50 = 42 cents and 5 coins to go.

The only way to get 2 cents is to have 2 pennies. That leaves 40 cents and 3 coins to go.

The only way to get 40 cents with 3 coins is 1 quarter, 1 dime, and 1 nickel.

So you have 3 quarters = 75 cents.

2 pennies = 2 cents.

1 dime = 10 cents.

1 nickel = 5 cents.

92 cents total and 7 coins.The only way to get 40 cents

The amounts of time employees at a large corporation work each day are normally distributed, with a mean of 7.5 hours and a stan
Ber [7]

Answer:

When sample size increases from n = 23 to n = 35, the mean of the distribution of sample means remains same but the standard deviation of the distribution of sample means decreases from 0.073 to 0.059.

Step-by-step explanation:

We are given the amounts of time employees at a large corporation work each day are normally distributed, with a mean of 7.5 hours and a standard deviation of 0.35 hour.

Random samples of size 23 and 35 are drawn from the population and the mean of each sample is determined.

Here, \mu = population mean = 7.5 hours

          \sigma = population standard deviation = 0.35 hour

<u><em /></u>

<u><em>Let </em></u>\bar X<u><em> = sample mean</em></u>

(a) The random samples of size of n = 23 is drawn from the population;

So, mean of the distribution of sample means = \mu = 7.5 hours

Standard deviation for the distribution of sample means is given by;

               s  =  \frac{\sigma}{\sqrt{n} } = \frac{0.35}{23} = 0.073

(b) The random samples of size of n = 35 is drawn from the population;

So, mean of the distribution of sample means = \mu = 7.5 hours

Standard deviation for the distribution of sample means is given by;

               s  =  \frac{\sigma}{\sqrt{n} } = } \frac{0.35}{\sqrt{35} } = 0.059

(c) So, as we can see that when sample size increases from n = 23 to n = 35, the mean of the distribution of sample means remains same but the standard deviation of the distribution of sample means decreases from 0.073 to 0.059.
