B- 1/2 the books are science books. You have to add the two fractions and subtract that from one.
Answer:
You would plot the following points, remembering that they’re in the form (x,y) = (time, height):
(1,35) (2,60) (3,92) (4,120) (5,175)
The ordered pairs would be closer together, and there would be 4 times more of them if you were to measure every 15 seconds instead. You would have a line with more points that were closer together.
500 (non smokers)÷ 25(random students out of the group)= 20 inches.
20 inches ÷ 74 inches= 3.70
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
