100 adults were surveyed and asked whether or not they had chosen a candidate to vote for in an upcoming election. Are theevents W = "is a woman' and C = "has chosen a candidate' independent? Why or why not?
Yes, because P(W & C) = P(W) + P(C).
No; because P(W & C) P(W) + P(C).
Yes; because P(W & C) = P(W) P(C).
No; because P(W & C)# P(W). P(C).

Answers

Answer: I just answered on USA Test prep

C.)

Yes; because P(W &C) = P(W) • P(C).

Hello!

The answers are:

3. Addition property of equality

4. 6x-7+7=12+7 - Simplification

7.x=(19)/(6)

Why?

To solve the problem, we need to start with the result of the second step:

6x-7=12

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

6x-7=12

Adding 7 to both sides, we have:

6x-7+7=12+7

For the step 4:

Now, for the 4th step, we have to simplify the expression:

6x-7+7=12+7

Then, simplifying, we have:

6x=19

For the step 7:

Simplificating, we divide each side of the equality by 6:

(6x)/(6)=(19)/(6) \n\nx=(19)/(6)

Have a nice day!

Students were surveyed about their favorite colors one fourth of the students preferred red 1/8 of the students preferred blue, and3/5 of the remaining students preferred green. If 15 students prefer green how many students were surveyed

Answers

Let us assume the total number of students surveyed = x
Then
Number of students preferring red = x/4
Number of students preferring blue = x/8
Then
Number of students remaining = x - [(x/4) + (x/8)]
                                                   =x - [(2x + x)/8)
                                                   = x - (3x/8)
                                                   = (8x - 3x)/8
                                                   = 5x/8
Number of students preferring the color green = (3/5) * (5x/8)
                                                                           = 3x/8
We also know that the total number of students preferring the color green is 15
So
3x/8 = 15
3x = 15 * 8
x = (15 * 8)/3
   = 5 * 8
   = 40
So in total 40 students were surveyed. I hope the procedure is clear to you.
