Step-by-step explanation:
Given : Suppose a bus arrives at a bus stop every 35 minutes
To Find: If you arrive at a bus stop at a random time, what is the probability that you will have to wait at least 20 minutes for the bus?
Solution:
A bus arrives at a bus stop every 35 minutes.
You arrive at a bus stop at a random time.
So, probability that you will wait at most 20 minutes =
So, The probability that you will wait at least 20 minutes =
=
=
=
Thus the probability that you will have to wait at least 20 minutes for the bus is

Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))
Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right
y = -2x
This has a y-intercept of 0, so the line intersects the y-axis/goes through the origin at (0,0)
The slope is -2 or , so from each point, you go down 2 units, and to the right 1 unit.
Function transformation involves changing the form of a function
The function g(x) is
The function is given as:
g(x) is an exponential function that passes through points (-2,2) and (-1,4).
An exponential function is represented as:
At point (-2,2), we have:
At point (-1,4), we have:
Divide both equations
Simplify
Apply law of indices
Rewrite as:
Substitute 2 for b in
This gives
Multiply both sides by 4
Substitute 8 for (a) and 2 for (b) in
Express as a function
Hence, the function g(x) is
