First. You have to look at what kind of proportionality it is.It is an Inverse Proportion.so you see the rate of change is 2.3
Answer: The required probability is 0.6.
Step-by-step explanation:
Since we have given that
It is uniformly distributed between 40 minutes and 90 minutes,
Probability that her trip will take longer than 60 minutes would be
here, a = 40, b = 90, α = 60
Hence, the required probability is 0.6.
Using SOH, the answer is 331.3
A)
The formula for direct variation is written as Y = KX, where k is the direct variation you need to solve for.
Y is the total amount raised and X would be the number of attendees:
100 = K5
Divide both sides by 5:
K = 100/5
K = 20
B. The constant of variation is K which is 20
C) Using the formula from A: y = kx, replace k with 20 and x with 60 and solve for y:
y = 20 * 60
y = 1200
The total is: $1,200
2. A relationship is proportional when the ratio is a constant number.The relationship is non proportional when the ratio varies between the different values.
