Answer:
should be subtracted.
Step-by-step explanation:
we find the polynomial that is subtracted from 7x^2-6x+5 to get the difference equal to x^2-x
7x^2-6x+5-polynomial=x^2-x
To get the polynomial subtract x^2-x from the given polynomial
So should be subtracted.
Answer:
0.11069
Step-by-step explanation:
We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.
P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =
I hope that works for you!
