Answer:
So the answer for this case would be n=247 rounded up to the nearest integer
Step-by-step explanation:
We know that the standard deviation is :
represent the deviation
The margin of error is given by this formula:
(a)
And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=247 rounded up to the nearest integer

Answer:
4
Step-by-step explanation:
if you do 80÷18 you get 4.4 repeating. so the most tony can get it 4
Okay so if the line goes through half of the circle it's called the radius. If it goes through the whole thing it's the diameter. The equation to find the circumference is pi times diameter. So the first one is 5pi, second is 4pi, third is 3pi, fourth is 6pi, and the last one is 2pi.
