Answer:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the margin of error desired
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 80%, the significance would be and the critical value for this case is , replacing into formula (b) we got:
So the answer for this case would be n=16 rounded up to the nearest integer
Would you like me to show the steps, or tell you the answer?
The area of the figure would be 234 in.
5 • 3 + 8 divided by 2
15 + 4
= 11
11 is the value of this expression.
Answer:
Step-by-step explanation:
slope-intercept equation for line of slope -5/2 and y-intercept -2:
y = (-5/2)x-2
put into standard form:
(5/2)x + y = -2
5x + 2y = -4
