The answer would be one of the following in the photo below....if not do you have a picture you could show me of the possible answers?
Answer:
6x
Step-by-step explanation:
3x*3x= 9x - 3x = 6x
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:
5/6
Step-by-step explanation:
There are 24 hours a day and a koala sleeps for 20 hours of it:
20/24
5/6
8(8 + X) = 16
64 + X = 16
-64 -64
X = -48
