A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.
Answer: no solution
Step-by-step explanation: after simplifying they are parallel which means they have no solutions
Po = 95
r = 15% = 0.15
t = 2023 - 2015 = 8
P = Po * e^(rt)
P = 95*e^(0.15*8)
P = 95*3.32
P = 315.41
The height of the cylinder is 2.86
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.
