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
8090 [49]

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

The distance from a point to a line is the length of the ____________ segment from the point to the line.
solniwko [45]

Answer: 1) Perpendicular

2) Concurrent

Step-by-step explanation:

The distance from a point to a line is the length of the perpendicular segment from the point to the line.

As Perpendicular segment is the shortest distance to the point of the line.

When three or more lines intersect at one point, they are concurrent.

Because Concurrent is a situation when three or more lines intersect each other at a single point.
