Answer:
wrong it is 667.95
Step-by-step explanation:
You are partially correct :) 2^SQR(10) x SQR(10) = 20
The answer is just 20
Answer:
So the answer for this case would be n=22547 rounded up to the nearest integer
Step-by-step explanation:
Let's define some notation
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
represent the margin of error desire
The margin of error is given by this formula:
(a)
And on this case we have that ME =+1 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 would be and the critical value , replacing into formula (b) we got:
So the answer for this case would be n=22547 rounded up to the nearest integer

without regard to its sign. So both shawn and brielle are correct since
both function will have the same answer, because it will just cancel out the

Answer:
(5x−1)(x−9)
Step-by-step explanation:
Factorise 5x²−46x+9
5x2−46x+9
=(5x−1)(x−9)
