Answer:
A,C,D
Step-by-step explanation:
The answer to this question is (2, -2) and (0, -2)
Why: imagine a graph with a line through it. When the line hits the y-axis (anywhere) the value for x is always zero. When you look at the answer, I chose, you can tell that in the second coordinate pair the first number is zero which represents x and the second number is -2 which is what you said y equals to.

Answer:
0.1587
Step-by-step explanation:
Here, mean=μ=100 and standard deviation=σ=16.
We have to find P(average MDI scores of 64 children > 102)=P(xbar>102).
n=64
μxbar=μ=100
σxbar=σ/√n=16/√64=16/8=2
P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)
P(xbar>102)=P(z>1)
P(xbar>102)=P(0<z<∞)-P(0<z<1)
P(xbar>102)=0.5-0.3413
P(xbar>102)=0.1587
Thus, the probability that the average is greater than 102 is 15.87%
