Answer:
9.1) k = 4.6
9.2) k = 6
Step-by-step explanation:
9.1)
To find constant of proportionality, k, divide both sides by 25
Constant of proportionality, k = 4.6
9.2)
To find constant of proportionality, k, divide both sides by 2.5
Constant of proportionality, k = 6
I think ..........
1 = 6 miles
1/2 or 0.5 = 3 miles
1 1/3 = 8 miles
15 min = 1.5
1 hour 30 min (1.5) = 9
45 min = 4.5
The rule is 10 min = 1 miles (check for yourself)

<span>1. a portion of a large group -> sample
the sample is the part that you select from a population to analyze.
2. choosing a sample so that every member has an equal chance of being chosen -> random sample
in a random sample any member of the group has the same probabilities to be selected.
3. choosing a sample from people who are under 15 years old -> biased sample
when you select based on a characteristic of the group you are running a biased sampling.
4. using the responses of a small group to make conclusions about the large group. -> estimating from a sample
statistics searches to infere information about a large group using the responses from a sample
