At a local company, the ages of all new employees hired during the last 10 years are normally distributed. the mean age is 38 years old, with a standard deviation of 10 years. find the percent of new employees that are no more than 30 years old. round to the nearest percent.

P = 21%

Step-by-step explanation:

We look for the percentage of employees who are not more than 30 years old.

This is:

Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.

We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to

Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.

This is:

Then we find the z-score

We know that:

μ = 38 years

years

So

Then

By symmetry of the distribution

Looking in the normal standard tables

Finally P = 21%

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
