Answer:
l = 16 feet
Step-by-step explanation:
P = a + b + c + d.
P = 2x + x + 2x + x = 48
6x = 48
x = 48/6
x = 8 feet
Thus, length = 2x = 2(8) = 16 feet
Hi!!! So to do this problem, you need to find the mean values for each sample. I will walk you through finding the mean of sample 1: first you want to add all of the values for sample 1, which are 4,5,2,4 and 3. Once you add those values you get 18. Then you must divide that 18 by the number of terms you added. The numbers you added were 4,5,2,4 and 3 like I said earlier which is 5 numbers. You divide 18 by 5 to get your mean, which is 3.6
Answer: (B) Sample 2
sample 1 mean = 3.6
sample 2 mean = 4.2
sample 3 mean = 3.8
sample 4 mean = 4
Answer: 5/3
One of the side lengths goes from 3 to 5. So, the scale factor is 5/3.
Hope that helped!
