At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 38 ye

N76 [4]

Answer:

P = 21%

Step-by-step explanation:

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

This is:

$P = \frac{x}{n} *100\%$

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 $P = \frac{x}{n}$

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

This is:

$P(X< 30)$

Then we find the z-score

$Z = \frac{X - \mu}{\sigma}$

We know that:

μ = 38 years

$\sigma = 10$ years

$Z = -0.8$

Then

$P (X$

By symmetry of the distribution

$P(Z0.8)$

Looking in the normal standard tables

$P(Z>0.8)=0.211$

Finally P = 21%

A Fruit Stand sells 6 oranges for $3.00 and grapefruit for $2.40 people buy 10 oranges and 11 grapefruits much does the fruit sp

kotykmax [81]

The correct answer is:

$31.40.

Explanation:

Since 6 oranges cost $3.00, we can divide to find the cost of one orange:

3.00/6 = $0.50. Each orange costs $0.50.

If ten oranges are bought, this would cost 10(0.50)=$5.00.

Each grapefruit costs $2.40; 11 of them would cost 11(2.40) = 26.40.

Together the total cost is $5+$26.40 = $31.40.
