Employment data at a large company reveal that 55 % of the workers are married, that 20 % are college graduates, and that 1/5 of the college graduates are married. what is the probability that a randomly chosen worker is: a) neither married nor a college graduate?

Probability of neither married nor a college graduate is 0.36

Step-by-step explanation:

We have the probability of the married workers and the college graduate,  we need the probability of not being married or graduate.  

The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.

So ,  the probability of not workers not being married is 1-55 %=45 %

The probability of not being a college graduate is 1-20 %= 80%

To get the probability of choose the 2 conditions we have to multiple both probabilities.  

Probability (neither married nor a college graduate)=0.45 x 0.80=0.36

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

answer: none of these answers are correct only the second half is
