Answer:
The correct answer is
(0.0128, 0.0532)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of
For this problem, we have that:
In a random sample of 300 circuits, 10 are defective. This means that and
Calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool.
So = 0.05, z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is
(0.0128, 0.0532)
Answer:
C.
Step-by-step explanation:
Volume of a Sphere =
Where volume of sphere = 81 π cm³
So, the equation becomes
81 π =
Answer:
76/15
Step-by-step explanation:
Add the drug combinations together
Drug A + B + C=2/5 + 5/3 + 9/3
The L.C.M of the denominators is 15
=6+25+45/15
=76/15
Or
=5 1/15
Allen needs to prepare 76/15 compound for the patient
Problem 14: The answer is choice A since the x coordinate flips in sigh (from positive to negative or vice versa). The y coordinate stays the same. This rule reflects the figure over the y axis.

Problem 15: The answer is choice A
cos(angle) = adjacent/hypotenuse
cos(B) = BC/AB
cos(B) = 12/13
Answer:
