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

The formula for compound interest is:

sveta [45]

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

$A = P(1 + \frac{r}{n})^{nt}$

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

$A = 500(1 + \frac{0.05}{365})^{365*5}$

$A = 500(1 + 0.000137)^{1825}$

$A = 500(1.000137)^{1825}$

$A = 500*1.2840$

Future value, A = $642

Find the rectangular coordinates of the point ( -3, 1/2 π)

alexdok [17]

Answer:

$x = -3 cos (\frac{\pi}{2})= 0$

$y = -3 sin (\frac{\pi}{2})= -3$

And then the rectangular coordinates for this case are :

$(x = 0 , y = -3)$

Step-by-step explanation:

We have the following point given $P = (-3, \frac{\pi}{2})$ and we want to conver from polar to rectangular coordinates and we need to use the following formulas:

$x = r cos \theta$

$y = r sin \theta$

For this case we have that:

$r = -3$

And:

$\theta = \frac{\pi}{2}$

Replacing we got:

$x = -3 cos (\frac{\pi}{2})= 0$

$y = -3 sin (\frac{\pi}{2})= -3$

And then the rectangular coordinates for this case are :

$(x = 0 , y = -3)$

PLEASE HELP!!!!!! the sum of a number times 10 and 15 is at most -17

Brilliant_brown [7]

Let the number = x

Writing the equation you have:

10x + 15 <= -17

Solve for x

Subtract 15 from both sides:

10x <= -32

Divide both sides by 10:

X <= -32/10

Simplify:

X <= -16/5 as a fraction or -3.2 as a decimal
