Employment data at a large company reveal that 59 % of the workers are married, that 43 % are college graduates, and that 1/3 of

Aleksandr-060686 [28]

Answer:

a. 74.63%

b. 33.63%

c. 87.67%

Step-by-step explanation:

If 59% (0.59) of the workers are married, then It means (100-59 = 41%) of the workers are not married.

If 43% (0.43) of the workers are College graduates, then it means (100-43= 57%) of the workers are not college graduates.

If 1/3 of college graduates are married, it means portion of graduate that are married = 1/3 * 43% = 1/3 * 0.43 = 0.1433.

For question a, Probability that the worker is neither married nor a college graduate becomes:

= (probability of not married) + (probability of not a graduate) - (probability of not married * not a graduate)

= 0.41 + 0.57 - (0.41*0.57) = 0.98 - 0.2337

= 0.7463 = 74.63%

For question b, probability that the worker is married but not a college graduate becomes:

=(probability of married) * (probability of not a graduate.)

= 0.59 * 0.57

= 0.3363 = 33.63%

For question c, probability that the worker is either married or a college graduate becomes:

=probability of marriage + probability of graduate - (probability of married and graduate)

= 0.59 + 0.43 - (0.1433)

= 0.8767. = 87.67%

Solve the equation. 1.5( 3y + 2) – y=2(8y – 6) y=?

kondor19780726 [428]

Okay. so basically you have to isolate the variable by dividing each side by factors that don't contain the variable. the answer is
y=1.2

Divide (-3x^2 - 9x) ÷ (x + 3) please explain/show work! <33

Stolb23 [73]

Step-by-step explanation:

 $( - 3 {x}^{2} - 9x) \div (x + 3)$ 

This is the original equation so you will open the brackets.

 $- 3 {x}^{2} - 9x \div x + 3$ 

The x will cross the division sign making it times x.

 $3 {x}^{2} - 9x \times x = 3$ 

So you will proceed to multiply the 9x by x making it;

 $3 {x}^{2} - 9 {x}^{2} = 3$ 

So you will subtract 9x² from 3x² which won't be possible so it will be negative.

 $- 6 {x}^{2} = 3$ 

Then you will square root both sides making it;

 $- \sqrt{6 {x}^{2} } = \sqrt{3}$ 

So the ² will cancel the √ leaving 

-6x=√3

-6x=1.73(Divide both sides by -6)

x=0.288

That's the final answer.
