Answer:
The correct option is (b).
Step-by-step explanation:
If X 
N (µ, σ²), then 
, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z N (0, 1).
The distribution of these z-variate is known as the standard normal distribution.
The mean and standard deviation of the active minutes of students is:
<em>μ</em> = 60 minutes
<em>σ </em> = 12 minutes
Compute the <em>z</em>-score for the student being active 48 minutes as follows:
Thus, the <em>z</em>-score for the student being active 48 minutes is -1.0.
The correct option is (b).

Answer:
(x+4)(x+8)
Step-by-step explanation:
when you use the FOIL method then you can check the work and make sure that this is correct.
Answer:
B because the line crosses the y axis at 4 and the slope will be -1 because the line is going downhill which therefore makes it negative
