Answer:

Hi There!

Your answer is:

Alyssa ran 2 and a half miles if she ran 2/3rds of the loop.

Step-by-step explanation:

1 loop= 3 & 3/4ths miles

WE NEED: 2/3rds of a loop

1 loop/ 3 = 3& 3/4ths miles /3

CHANGE MILES TO IMPROPER FRACTION!

1/3 loop = 15/4ths divided by 3

Multiply 15/4ths by the inverse of 3

15/4ths * 1/3 = 15/ 12

SIMPLIFY

1 & 3/12 or 1& 1/4

1/3loop = 1 & 1/4th mile

To get 2/3rds loop, multiply both sides by 2

2/3rds loop = 2 & 1/2 Miles

Hope this helps

Step-by-step explanation:

One loop= 3+3/4= 15/4 miles

Two-third of the loop= 2/3*(15/4)

= 5/2 = 2.5 miles

Hope it helps :)

Heights of men have a bell-shaped distribution, with a mean of 176 cm and a standard deviation of 7 cm. Using the Empirical Rule
Vaselesa [24]

Answer:

a) 68% of the men fall between 169 cm and 183 cm of height.

b) 95% of the men will fall between 162 cm and 190 cm.

c) It is unusual for a man to be more than 197 cm tall.

Step-by-step explanation:

The 68-95-99.5 empirical rule can be used to solve this problem.

This values correspond to the percentage of data that falls within in a band around the mean with two, four and six standard deviations of width.

<em>a) What is the approximate percentage of men between 169 and 183 cm? </em>

To calculate this in an empirical way, we compare the values of this interval with the mean and the standard deviation and can be seen that this interval is one-standard deviation around the mean:

\mu-\sigma=176-7=169\\\mu+\sigma=176+7=183

Empirically, for bell-shaped distributions and approximately normal, it can be said that 68% of the men fall between 169 cm and 183 cm of height.

<em>b) Between which 2 heights would 95% of men fall?</em>

This corresponds to ±2 standard deviations off the mean.

\mu-2\sigma=176-2*7=162\\\\\mu+2\sigma=176+2*7=190

95% of the men will fall between 162 cm and 190 cm.

<em>c) Is it unusual for a man to be more than 197 cm tall?</em>

The number of standard deviations of distance from the mean is

n=(197-176)/7=3

The percentage that lies outside 3 sigmas is 0.5%, so only 0.25% is expected to be 197 cm.

It can be said that is unusual for a man to be more than 197 cm tall.
