Answer:
So the answer for this case would be n=2663 rounded up to the nearest integer
Step-by-step explanation:
We have the following info:
margin of error desired
the standard deviation for this case
The margin of error is given by this formula:
(a)
And on this case we have that ME =50 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 99% of confidence interval now can be founded using the normal distribution. The significance is
. And for this case would be
, replacing into formula (b) we got:
So the answer for this case would be n=2663 rounded up to the nearest integer
Answer:
Your answer should be 647.51
Explanation : the price was 215.949 in December, 2009.
the price was 233.049 in December, 2013.

multiply that by 600 and got 647.5112179.
Hey there!
If x = -3 then replace "x" with -3
New equation: -3^-2
(-1 × 3)^-2
(-1 / 3 )× 3
3 × 3 = 3^3 = 9 (Solving for your denominator)
(-1/3)^2
= (1/9)
This your answer is: 1/9
Good luck on your assignment and enjoy your day!
