Answer:
1. b. The common difference is 0.39
2. no good answer (Zach's method is exponential; Victoria's is linear)
Step-by-step explanation:
1. The differences in mileage are ...
24.39 -24 = 0.39
24.78 -24.39 = 0.39
25.17 -24.78 = 0.39
The common difference is 0.39.
____
2. Zach's monthly times are ...
10, 20, 40, 80
The differences are ...
10, 20, 40
The ratios are ...
20/10 = 40/20 = 80/40 = 2
Zach's times have a common ratio, so are exponential.
__
Victoria's monthly times are ...
35, 50, 65, 80
The differences are ...
15, 15, 15
Victoria's times have a common difference, so are linear.
__
The choices are ...
a. both exponential; common factor . . . . correct for Zach; not for Victoria
b. Zach's is linear (has equal factor) . . . incorrect
c. both exponential; common difference . . . incorrect
d. Victoria's is linear . . . . correct for Victoria
Choice D describes Victoria's method. Choice A is correct regarding Zach's method, but incorrect regarding Victoria's.
Choices B and C are not self-consistent, so are incorrect on their face.
There is no good choice.
Set up a proportion
75/100= 9 baskets/ x attempts
The ratio of numerator to denominator should be 75/100 which simplifies to 3/4. 3/4= 9/x
3*3=9, 4*3=12
x=12
Final answer: 12 attempts
