Answer:
Step-by-step explanation:
Equation of a line is given as
Where,
m = slope of the line =
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.
Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m
b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>
Answer:
The expectation is
Step-by-step explanation:
From the question we are told that
The first offer is
The second offer is
The third offer is
The number of tickets is
The price of each ticket is
Generally expectation is mathematically represented as
given that they just offer one
Now
given that they just offer one
Now
given that they offer five
Hence the expectation is evaluated as
Now given that the price for a ticket is
The actual expectation when price of ticket has been removed is
