Answer:

(A).  \frac{15}{2} + \frac{33}{4} <em>k</em>

\frac{3}{4} × 2(2 + 4k + 3 + \frac{3}{2} k ) = \frac{3}{2} ( 5 + \frac{11}{2} k ) = \frac{15}{2} + \frac{33}{4} k

Jack rolls a number cube twice. What is the probability that the sum of the 2 rolls is less than 8 given that the first roll is
disa [49]
If the first roll is a 4, the possibilities to add less than 8 are that the second cube roll is 1, 2 or 3.

These are 3 different events out of 6 possilbe ones, which is 3 / 6 = 1 / 2; i.e. half of times.

Then the answer is the first option: 1 / 2

What does the equation inverse of the function found in part b represent in the contract of the problem ? explain your answer .
gavmur [86]

Answer:

f^{-1}(x) =\frac{x}{3} - 5

The inverse function is to calculate the number of rides; given the amount paid

Step-by-step explanation:

Given

Admission = 15

Ride = 3 per ride

Required

Explain the inverse function

First, we calculate the function

Let x represents the number of rides

So:

f(x) = Admission + Ride * x

f(x) = 15 + 3 * x

f(x) = 15 + 3x

For the inverse function, we have:

y = 15 + 3x

Swap x and y

x = 15 + 3y

Make 3y the subject

3y = x - 15

Make y the subject

y =\frac{x}{3} - 5

Replace y with the inverse function

f^{-1}(x) =\frac{x}{3} - 5

The above is to calculate the number of rides; given the amount paid

X/4 = 3/8 solve for x
Andrei [34K]
The ratio of 4 to 8 simplifies to 1:2. X will therefore be 3/2, as 3/2:3 simplifies to 1/2 (3 = 6/2).
