The following is an example of a cluster sampling.
Cluster sampling<span> is a </span>sampling<span> technique used when "natural" but relatively heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this technique, the total population is divided into these groups (or </span>clusters) and a simple randomsample<span> of the groups is selected.</span>

Answer:
12 throws
Step-by-step explanation:
Each time Glenda practiced her free throws, she recorded the
number of made baskets in a stem-and-leaf plot.

Number of Times she made less than 10 free throws =4
Number of Times she made more than 26 free throws =8
Total=4+8=12
She made 12 throws which were either less than 10 or more than 26.
L=2w
a=50
50=2w×w
25=w squared
5=w
l=2w
l=2(5)
l=10
5+5+10+10=25
perimeter=25 meters
I think number 1 is 15 and number 2 is 80. Have a nice day!
(15/124)x(230/30) divided by (230/124)= 1/2
That's what I got.
