According to a survey by the National Center for Health Statistics, the heights of adult men in the U. S. are normally distributed with a mean of 68 inches and a standard deviation of 2.75 inches. What is the probability that adult men are at most 59 inches or at least 74 inches

0.0151 is the probability  that adult men are at most 59 inches or at least 74 inches.  

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 68 inches

Standard Deviation, σ = 2.75 inches

We are given that the distribution of heights of adult men is a bell shaped distribution that is a normal distribution.

Formula:

P(height between 59 and 74)

0.0151 is the probability  that adult men are at most 59 inches or at least 74 inches.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
