Answer:u=19/7 or 2.714286 or 2 5/7
Step-by-step explanation:
−14u+32=−6
Step 1: Subtract 32 from both sides.
-14u+32-32=-6-32
-14u=-38
Step 2: Divide both sides by -14.
-14u/-14=-38/-14
U=19/7

Answer:
0.0110
Step-by-step explanation:
This is a Poisson distribution problem
Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = 3 automobiles per minute
x = variable whose probability is required = more than 9 automobiles in a minute
P(X>9) = 1 - P(X ≤ 9)
P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)
P(X < 9) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7) + P(X=8) + P(X=9)
So, computing this one at a time, and summing it all up
P(X ≤ 9) = 0.99620
P(X>9) = 1 - P(X ≤ 9) = 1 - 0.99890 = 0.0110
Teh answer is 1/12. 1/4+ 2/3 is 11/12. First, you need to find the common denominator of 4 and 3, and that is 12.Then, you multiply 1*3 because 4*3 is 12.You then have the fraction of 3/12. Then, you multiply 2*4 because again, what you do to the top, you also do to the bottom, so you would also have the fraction of 8/12.The rest is easy. 3/12 + 8/12 is 11/12.And the missing piece of 11/12 is 1/12, because that made it whole.
Hope that helps!
