Answer: The probability that you select a women who passes is 1/2.
First, let's look at the men. 21 of the 84 test takers were men. If the ratio is 5:2 for failing. Then, 15 failed and 6 passes.
Second, let's look at the women. 63 of the test takers were women. If double the number passed, then 42 passed and 21 failed.
The chances that a random person was a women who passes is 42 out of 84 or 1/2.
1 gig is 1,000,000,000 bytes.
We can do 15 times 1,000,000,000 to get 15,000,000,000.
So your answer is 15,000,000,000 gigs.
Answer:
B. x = -5 +/- √30.
Step-by-step explanation:
2x^2 + 20x = 10
2(x^2 + 10x) = 10
2[ (x + 5)^2 - 25 ] =10
2(x + 5)^2 - 50 = 10
2(x + 5)^2 = 60
(x + 5)^2 = 30
x + 5 = +/- √30
x = -5 +/- √30.
