The formula to find the perimeter of a rectangle is P = 2(l + w), where p is perimeter, l is length and w is width,
The length of the playground is 16 yards, and the width is 20, because 16 x 20 = 320 and 16 + 4 = 20.
P = 2(l + w)
P = 2(16 + 20)
P = 2(36)
P = 72.
The perimeter is 72 yards.
Hope this helps!!
Answer:

Step-by-step explanation:
We can just add up all of these fractions:
2 1/8 + 7/8 = 2 8/8 = 3
8 5/8 + 4/8 = 8 9/8 = 9 1/8
3 + 9 1/8 = 
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.

Step-by-step explanation:
As with many multiple-choice questions, the appropriate choices can often be determined with a simple test. Here, you only need to look at the values of the constants. (Those are ringed in blue.)
