Answer:
So the answer for this case would be n=107 rounded up to the nearest integer
Step-by-step explanation:
Information given
the sample mean
the sample deviation
the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =0.001 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We can use as estimator of the real population deviation the sample deviation for this case 
/ The critical value for 99% of confidence interval is given by 
, replacing into formula (b) we got:
So the answer for this case would be n=107 rounded up to the nearest integer
Profit function - Cost function = Revenue function
Your answer will most likely be D. h > 42 and h must be a positive number. Reasoning: H has to be greater than 42 to ride the ride, and it cannot be a negative number because H has to be greater than 42 and if you make it negative, it will be less than 42
Answer:
Step-by-step explanation:
Answer: 7/4
Answer:
Step-by-step explanation:
(x + y)² - (x - y)² = 4xy
t = a² - b²
= (√8+2)²-(√8-2)² (here, x = √8 & y = 2}
=4*√8*2
=8√8
=8√2*2*2
=8*2√2
=16√2
