for c) is 16.3 years
Answer:
south
Step-by-step explanation:
telling what way it is north south east
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
x | y
-
2 | 10
4 | 20
6 | 30
just plug the x values (2,4,6) into x in the equation and you get your y! example would be y=5(2) so y=10
