Answer:
Step-by-step explanation:
Collect like terms
If P(A) times P(B) is equal to P(A n B), then that shows the events are independent. Otherwise, they are dependent. When I write "A n B", I mean "A intersect B". The intersect symbol looks similar to the lowercase letter n.
P(A)*P(B) = (3/4)*(2/5) = (3*2)/(4*5) = 6/20 = 3/10
Since that result is not the same as P(A n B) = 1/3, this means that the events are not independent. They are dependent events. The answer is choice D
Answer:
z-score
Step-by-step explanation:
Since we are given the mean and standard deviation of a national test (whole population) it is fair to assume a large population size, and the use of the z-score would be more appropriate, since the z-score is used for the standardization of population data, while the t-score is recommended for samples or small populations.
Answer:
No, because they do not have the same area.
Step-by-step explanation:
For the piece of paper to cover once without overlap or gaps, it must have the same area as the the total surface area of the prism.
The total surface area of the rectangular prism is: 
The area of the rectangular sheet is:
Since the area of the piece of paper is more than the surface area of the rectangular prism there will be an overlap.
