Been a while but I'm gonna try..! Okay!
For the Focus use the vertex to find it. (9/2 , 0)
For the directrix I believe it is. x = -9/2
Answer:
Step-by-step explanation:
no
Answer:
0.59375
Step-by-step explanation:
In a uniform distribution the probability that the time t is greater than any given value, X, is:
In this problem, the limits of the distribution are a = 0 and b = 8 minutes.
For X =3.25 minutes:
The probability that a randomly selected passenger has a waiting time greater than 3.25 minutes is 0.59375.
Answer:
well, I think b would be correct if we use the cosine rule but according to my calculations a is the answer when we use sin rule but I'm not really sure.
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}
