The distance between (2,5) and (6,1) is:

The distance between the fourth vertex and (4,-1) should also be 4√2
The only point that gives us that distance is
B. (0,3)
Your final answer is
B. (0,3)
Answer:

Step-by-step explanation:
We are given the following in the question:
Population mean = 200
Population standard deviation = 50
Sample size, n = 100
We have to estimate the expected value of the sample mean.
The best point estimate for the sample mean is the population mean.
Thus, we can write:

Thus, the expected value of the sample mean is 200.
Answer:
Step-by-step explanation:
Hello, For this problem just multiply 20 (min) with 50 (child) , because that how long he takes to get to every child.
20 × 50 = 1,000
I hope my answer helped.
