The Centers for Disease Control and Prevention reports that 25% of baby boys 6–8 months old in the United States weigh more
than 20 pounds. A sample of 150 babies is studied. (7. ~ 9.)

7. Approximate the probability that more than 40 weigh more than 20
pounds.

(A) 0.2851 (B) 0.2858 (C) 0.2921 (D) 0.2925
8. Approximate the probability that 35 or fewer weigh more than 20
pounds.

(A) 0.3528 (B) 0.3530 (C) 0.3534 (D) 0.3536
9. Approximate the probability that the number who weigh more than 20
pounds is between 30 and 40, exclusive.

(A) 0.5532 (B) 0.5535 (C) 0.5538 (D) 0.5540

answer: 2 and 1

step-by-step explanation: got this question

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be
