Which sentence correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14
denis-greek [22]

Answer:

Option (c) is correct.

68% of the data points lie between 10 and 18.

Step-by-step explanation:

Given :  a normal distribution with a standard deviation of 4 and a mean of 14

We have to choose the  sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.

Since, given 68% data.

We know mean of data lies in middle.

And standard deviation is distribute equally about the mean that is 50% of values less than the mean  and 50% greater than the mean.

So, 68% of data lies

mean - standard deviation = 14 - 4 = 10

mean + standard deviation = 14 + 4 = 18

So, 68% of the data points lie between 10 and 18.

F(x) = x^2+1 and g(x) = x-4 <br> (f/g)(5)=
Nezavi [6.7K]

The value of the composite function is (f/g)(5)= 26

<h3>How to evaluate the composite function?</h3>

The functions are given as:

f(x) = x^2+1 and g(x) = x-4

To calculate the composite function, we use the following formula

(f/g)(x)= f(x)/g(x)

So, we have:

(f/g)(5)= f(5)/g(5)

Calculate f(5) and g(5)

f(5) = 5^2+1 and g(5) = 5-4

This gives

f(5) = 26 and g(5) = 1

Substitute f(5) = 26 and g(5) = 1 in (f/g)(5)= f(5)/g(5)

(f/g)(5)= 26/1

Evaluate

(f/g)(5)= 26

Hence, the value of the composite function is (f/g)(5)= 26
