Answer:
#3
Step-by-step explanation:
You can tell if a table is linear, if the slope is constant within the graph. #3 is the only option that has a constant slope. In the others, if you pick different points from that same table the slope changes. That is how you know that is not a linear function.
Answer:
x^2 + 2x + 3
Step-by-step explanation:
Answer:
n = - 30
Step-by-step explanation:
Eight plus the quotient of a number and 3 is −2
Expressing in mathematical terms, we have;
8 + (n/3) = -2
To solve for n;
Multiply all through by 3.
3*8 + 3(n/3) = 3 * (-2 )
24 + n = - 6
n = -6 - 24
n = - 30

Answer:
C. 2.937
Step-by-step explanation:
Given the following :
H0 : p = 0.25
H1 : p > 0.25
Number of observations (n) = 647
p' = 30% = 0.3
SD = sqrt[(p(1 - p) / n)]
1 - p = 1 - 0.25 = 0.75
SD = sqrt[(0.25 * 0.75) / 647]
SD = sqrt[0.0002897]
SD = 0.0170234
Z = (p' - p) / SD
Z = (0.3 - 0.25) / 0.0170234
Z = 0.05 / 0.0170234
Z = 2.9371187 = 2.937
