Of a company’s 85 employees, 60 work full time and 40 are married. Half of the fulltime workers are married.
zvonat [6]

It is implied from the given conditions that

Unmarried employees = 45

Unmarried employees that work full time = 30

Part time working employees = 25

Unmarried employees that work part time = 15

Married employees that work part time = 10

Thus

The probability of a part time employee = 25/85

The probability of an unmarried employee = 45/85

Hence probability that an employee works part time or is not married = (25/85) + (45/85)

= (25 + 45) / 85

You deposit all of your graduation money, $2,560, into an account earning 3.5% interest, compounded annually. You want to let it
gladu [14]

Answer:

To calculate compounded interest, use the compound interest formula.

A(t)=P(1+rn)n⋅t

Recognize the information given in the problem.

P=2560,r=0.035,n=1,t=4

Substitute the values into the appropriate position in the formula.

A(4)=2560(1+0.0351)1⋅4

Simplify by multiplying and dividing by 1.

A(4)=2560(1+0.035)4

Simplify using the order of operations.

A(4)=$2,937.66

The balance at the end of 4 years would be $2,937.66.
