Answer:
So the answer for this case would be n=220 rounded up to the nearest integer
Step-by-step explanation:
Information given
represent the population deviation
represent the margin of error
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =5 and we are interested in order to find the value of n, if we solve n from equation (4) we got:
(b)
The critical value for 90% of confidence interval now can be founded using the normal distribution. The significance level is
and the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=220 rounded up to the nearest integer

Answer:
I think x = 4.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x + x +10 + 5x + 2x + 2 =56
(3x + x + 5x + 2x) + (10 + 2) = 56 (Combine Like Terms)
11x + 12 = 56
11x + 12 = 56
Step 2: Subtract 12 from both sides.
11x + 12 − 12 = 56 − 12
11x = 44
Step 3: Divide both sides by 11.
11x/11 = 44/11
x = 4
