Answer:
(D) 200 men and 2,000 women
Step-by-step explanation:
To have an approximately normal distribution for the difference between proportions, we have to have sample sizes that are big enough to satisfy this conditions:
For men, we have p=0.08, so we have:
The sample size for men has to be at least 125 individuals.
For women, we have p=0.005:
The sample size for women has to be at least 2000 individuals.
The option that satisfy the requirements for men and women is Option D, as the others don't have enough sample size for women.
Your answer is c, 638.54 − 159.50 + x ≥ 500; x ≥ $20.96
Answer:
8
Step-by-step explanation:
The median is the segment from vertex B to the midpoint of AC. That midpoint (D) is ...
D = (A + C)/2 = ((-6, 7) +(-2, -9))/2 = (-8, -2)/2
D = (-4, -1)
The length of the midpoint is the length of the segment DB between (-4, -1) and (4, -1). These points both have the same y-coordinate, so the length is the difference of x-coordinates: 4 -(-4) = 8.
For this case we have the following equation:
From here, we must substitute ordered pairs of the form:
(x, y)
If the ordered pair satisfies the equation, then it belongs to the line.
We have then:
For (8, 5):
We substitute the following values:
We observe that the equation is not satisfied and therefore, this point does not belong to the line.
Since one of the points does not belong to the line, then the equation is not a good model.
Answer:
It is not a good model. One of the points does not belong to the line.
