Answer:
k=-6
Step-by-step explanation:
Answered questions (total) = 21
Correct questions = 6
Incorrect questions = 21 - 6 = 15
Not answered questions = 4
6 x 3 = 18
15 x -2 = -30
4 x 0 = 0
18 - 30 + 0 = -12
The student scored -12 points.
Hope this helps!! :)

Answer: 24</h3>
The first coefficient is 8 and the constant term is 3.
p = 8 and q = 3 leads to p*q = 8*3 = 24.
If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.

P(X=1) = 0.09
P(X < 5) = 0.09 + 0.36
P(X >= 2) = .36 + .23 + .09 + .23
P(2 <= X <= 7) = .36 + .23
