[round percentages to the nearest tenth] 13 points a) The new pass rate is percentage points above the old rate. b) The new rate is percent more than the old rate. c) The new pass rate is percent of the old pass rate. Problem-16: In class, I may have mentioned that if the Earth was shrunk down to the size of an orange with about 3 inch diameter, then relative to the diameter of the Sun, you would need to line up about 110 oranges also may have mentioned that the scale factor was about I to 160 million. Use the following NASA data to the exact scale factor: Earth diameter- 7926 miles. 5 points) Table for Exercise 3B-53 Planet Diameter (kilometers Average-distance-from-Sun (kilomet

Explanation / Answer

15.

Old pass percentage = 62%

New pass percentage = 71%

a) The new pass percentage is 71-62 = 9% above the old rate

b) If we take 62 as 100% then 71 is 114.5%

(71/62 * 100)=114.5

Therefore or answer for b is 114.5 - 100 = 14.5

c) The new pass rate is 114.5% of the old pass rate

For PROBLEM 16 the NASA table is not captured in the image. So, I cannot give the answer for this. Table needed for reference.
