Answer:
probably about 3.5
Step-by-step explanation:
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
Answer: x^2 - 13x + 13
Step-by-step explanation:
6 x 6 = 36
6 + 6 = 12
The answer is 6.
Well it has to add up to 180 So try to figure out the letters like c and b
