Question

Please help with a couple of questions!

Answer 1

yes...

Answer 2

This is the location you are supposed to type your question :)

Answer 3

Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P = {1, 2, 3, 4}. What is P'? (1 point)

{5, 6, 7, 8}
{1, 2, 3, 4, 5, 6, 7, 8}
{1, 2, 3, 4}
cannot be determined

Answer 4

If P = {1, 2, 3, 4}
What else could it equal?

Answer 5

{5, 6, 7, 8} ???

Answer 6

Let someone else weigh in on this as well, I'm not 100% certain.

Answer 7

yeah?

Answer 8

Sorry, did not see the P' prime. I am not sure what the answer is.

Answer 9

ok thanks anyways

Answer 10

you are correct.

Answer 11

would it be B???

Answer 12

so its A????

Answer 13

Okay: P' prime means the complement of the set P. If your set P = {1,2,3,4} in the universal set of U = {1, 2, 3, 4, 5, 6, 7, 8}, then P' prime is the complement of P, which is the remaining numbers in the universal set.
I believe you were right, the answer is P' = {5, 6, 7, 8}

Answer 14

yea, i think it's a

Answer 15

ok cool can you help with another one?

Answer 16

Your goal is to save at least $360.00 over the next 6 weeks. How much money must you save each week in order to meet that goal? Write and solve an inequality. (1 point)

6 + x ≥ 360; x ≥ 354
60x ≤ 360; x ≤ 10
x/6 ≤ 360; x ≤ 2,160
6x ≥ 360; x ≥ 60

Answer 17

Ouch, these are tough for me...You may want someone elses input :)

Answer 18

ya tough for me too!

Answer 19

I'll give it a shot.

Answer 20

d. if x is the amount of money you get each week and you have 6 weeks, it's 6x

Answer 21

oh cool so it is D i was about to say c lol

Answer 22

d is the only choice with 6x

Answer 23

A student scored 78 and 95 on his first two quizzes. Use a compound inequality to find the possible values for a third quiz score that would give him an average between 80 and 90, inclusive.
67 ≤ x ≤ 97
78 ≤ x ≤ 95
80 ≤ x ≤ 90
86 ≤ x ≤ 87

Answer 24

would this one be B???
