The first step would be D
keeping in mind that parallel lines have the same exact slope, hmmmm what's the slope of the line above anyway?
so we're really looking for the equation of a line whose slope is 1/3 and runs through (18,2)
Answer:
-11 and lower
Step-by-step explanation:
it's saying that -10 is as low as the number can possibly be or equal to it.
Answer:
B
Step-by-step explanation:
First thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
here, x = 130, mean = 120 and SD = 10
Substituting these values
z-score = (130-120)/10 = 10/10 = 1
So the probability we want to calculate is;
P(z ≥ 1) = 1 - P(z <1)
From standard score table, P(z <1) = 0.15866
P(z ≥ 1) = 1-0.15866 = 0.84134
