<span>You are given the waiting times between a subway departure schedule and the arrival of a passenger that are uniformly distributed between 0 and 6 minutes. You are asked to find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes.
Le us denote P as the probability that the randomly selected passenger has a waiting time greater than 3.25 minutes.
P = (length of the shaded region) x (height of the shaded region)
P = (6 - 3.25) * (0.167)
P = 2.75 * 0.167
P = 0.40915
P = 0.41</span><span />
Y = x^2 cos x
y' = x^2 * -sin x + cos x * 2x
= 2x cos x - x^2 sin x
= x ( 2 cos x - x sin x)
Answer:
98 cm²
Step-by-step explanation:
area of rectangle = length * width
length = 14 cm, width = 14/2 = 7 cm
area = 14 * 7 = 98 cm²
Answer: there are 37 high school students on the bus
Step-by-step explanation:
h+m=54 total number of students
h= 2m+3 total number of HS students
2m+3+m=54 Substitute 2m+3 in for h
3m+3=54
3m=51
m=17
h+17=54
h= 37
Answer:
2x + 3y = -21
Step-by-step explanation:
Parallel lines have same slope.
2x + 3y = -21
3y = - 2x - 21
y =
