Step-by-step explanation:
If A = 0, then Ax + By = C would be 0x + By = C.
The graph will be a horizontal line.
268.08
V=4/3(pi)r(cubed)
Plug and chug —> the volume of this sphere is about(squiggly equality sign) 268.08 feet
What you have to do is look at the problem and read carefully. You see that Lori finished 25 math problem at home, and she finished more in school. So, that leads that we can t divide or subtract because that would give us a smaller number then 25. We have either addition or multiplication. It would be multiplication because you says 4 TIMES, which is a key word to multiplication. You take the amount of problems at home and MULTIPLY them by 4. Doing 25 times 4 which gives you 100.
Answer:
a)
And rounded up we have that n=543
b)
And rounded up we have that n=1509
c)
And rounded up we have that n=13573
Step-by-step explanation:
For this case since we don't have previous info we can assume that the best estimator for the true proportion is
The margin of error for the proportion interval is given by this formula:
(a)
Part a
The significance level is The critical value would be for this case:
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=543
Part b
And rounded up we have that n=1509
Part c
And rounded up we have that n=13573
