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:
2.01
Step-by-step explanation:
Assume x is cost of each bottle of juice.
2.75 + 8x = 18.83
8x = 18.83 - 2.75
8x= 16.08
x= 16.08 ÷ 8
x= 2.01
Answer:
40
Step-by-step explanation:
Put 4 where x is and evaluate.
... f(4) = 3·4² -2·4
... f(4) = 3·16 - 8
... f(4) = 48 - 8 = 40
Y = -12x + 2
The graph is a straight line....true, it is linear
The line does not pass thru the origin (0,0).....true, it does not
The line passes thru the point (0,-2)...false, it does not
The y int of the line is 2......true, it is
89.548 + 324 + 105
= 89,548 + 429
= 89, 977 dollars
