So 119 out of 250 people had a pool in their backyard...119/250 = 47.6%
so out of 10,000 people, expected value of ones with a pool is :
47.6% of 10,000 ...
0.476 * 10,000 = 4760 people <===
Answer:
The answer is B
Step-by-step explanation:

Then you have to solve it :
Perimeter equals all sides added together so you would add all the numbers given together. For the side, without a number, you take the number above it and subtract 40.5 by 17.5 and that's your missing number. I think the answer is A. 143.1.
Hope this helps!
