Answer:

The answer to your question is 140 and 20.

Step-by-step explanation:

You can easily just divide 28 by two and you’ll get 14 and 2. But to get 2800, you need to multiply those factors by ten. 140 x 20 = 2800

1) The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years. Using the

Answer:

1) 68%

2) 68%

Step-by-step explanation:

<h2>1) The ages of trees</h2>

We know the mean and the standard deviation.

The mean is:

$\mu=25$

The standard deviation is:

$\sigma=5$

The Z-score formula is:

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

For x=20 the Z-score is:

$Z_{20}=\frac{20-25}{5}=-1$

For x=30 the Z-score is:

$Z_{30}=\frac{30-25}{5}=1$

Then we look for the percentage of the data that is between $-1$ deviations from the mean.

According to the empirical rule 68% of the data is less than 1 standard deviations of the mean. This means that 68% of the trees are between 20 and 30 years old

<h2>2) Pizza delivery </h2>

First we calculate the Z-scores

We know the mean and the standard deviation.

The mean is:

$\mu=27$

The standard deviation is:

$\sigma=3$

The z-score formula is:

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

For x=24 the Z-score is:

$Z_{24}=\frac{24-27}{3}=-1$

For x=30 the Z-score is:

$Z_{30}=\frac{30-27}{3}=1$

Then we look for the percentage of the data that is between $-1$ deviations from the mean.

According to the empirical rule 68% of the data is less than 1 standard deviations of the mean. This means that 68% of pizzas are delivered between 24 and 30 minutes
