Answer:

Carlos and Pamela drove 120 miles on the first day, 240 miles on the second day, and 290 miles on the third day.

Step-by-step explanation:

Let x be the number of miles driven on the first day.

Then they drove twice as many miles, or 2x on the second day

and 50 miles more than the second day's, so 2x + 50

The total is 650 across all three days, so we'll take the sum.

x + 2x + (2x + 50) = 650

Combine like terms on the left

5x + 50 = 650

Subtract 50 on both sides

5x = 600

Divide by 5 on both sides

x = 120

Check work:

120 + 2(120) + 2(120) + 50 = 650

120 + 240 + 240 + 50 = 650

600 + 50 = 650

650 = 650

So they drove 120 miles on the first day

2*120 = 240 miles on the second day

and 2*120 + 50 = 240 + 50 = 290 miles on the third day

Answer:

Cluster Sampling

Step-by-step explanation:

I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book). Researchers then select random groups (three random pages) with a simple random or systematic random sampling technique for data collection and data analysis(interviews).

so that appears to be what is happening in this scenario.
