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:
$2662.5 is the answer in my opinion
Answer:
5x+3y+5/2(5 over 2)
Step-by-step explanation:
Divide 10 by 2
divide 6 by 2
divide 5 by 2 and you stay at 5/2
Factor 16x^2 + 68x +42
16x^2 + 68x + 48
= 2(4x + 3)(2x + 7)
answer = 2(4x +3)(2x + 7)
