Answer:
The sample size needed is 40000.
Step-by-step explanation:
The sample size needed is:
Use this formula to determine the sample size needed for a margin of error of 0.005
This is n when 
. So
The sample size needed is 40000.
Yes you are right . In any triangle the 3 medians intersect in one point called centroid
It's a little hard to see, but I'm almost positive the y intercept is -1.
Remember, the y intercept is wherever the line intercepts in the y axis 0.

Answer:
Assuming that a and b are not the hypotenuse then B would be equal to A, so B would equal 25m
Step-by-step explanation:
I hope this is right, you didn't put a picture.
-7n + 9 because the common difference is -7, so you have -7n, and then by plugging in the term numbers and the values, you find out that you need to add 9 to the -7n, so the answer is -7n + 9
