At a local company, the ages of all new employees hired during the last 10 years are normally distributed. the mean age is 34 years old, with a standard deviation of 10 years. find the percent of new employees that are no more than 40 years old. round to the nearest percent.

P = 73%

Step-by-step explanation:

We look for the percentage of employees who are not more than 40 years old.

This is:

Where x is the number of new employees who are not over 40 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 40 years old is equal to

Then we can solve this problem by looking for the probability that a new employee selected at random is not more than 40 years old.

This is:

Then we find the z-score

We know that:

μ = 34 years

years

So

Then

So we have

Looking in the normal standard tables:

Finally P = 73%

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
