Answer:
13) A 14) C 15) B 16) C 17) C 28) A 29) B
Step-by-step explanation:
13) 3 left-handed total out of 50 total people
3/50 = 0.06 = 6%
14) 36 + 32 + 51 + 31 + 30 + 42 + 56 + 32 + 43 + 54 + +26 + 43 + 38 + 43 + 28 = 585 585/15 = 39
15) At (1,15) Jason works 1 hour and gets paid 15 dollars. This shows the unit rate or hourly pay rate.
16) 30, 32, 35, 38, 42, 46, 47, 51 Order the numbers from least to greatest. Cross off one from the left and one from the right until you have one number remaining. In this case, you have 38 and 42 remaining. Add both numbers together and divide by 2. 38 + 42 = 80/2 = 40
17) To find out how much to drive on the fist two days, you need to find 75% of 932.4 miles. 0.75 x 932.4 = 699.3 ≈ 700 miles. Divide this by 2 to find how much distance per day for two days. 700/2 = 350 miles.
28) (-4.8y + 20.1) - (12.7y + 9.3) Subtract the two equations
-17.5y + 10.8
29) The proportion for graph B is 2. Although graph C also has a constant proportion, it doesn't start at the origin.
