Answer:
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
Step-by-step explanation:
We take the estimate from the website, and expand for all buyers, to find the proportion that use their smartphones.
400 users of the website were randomly sampled from the existing database and 180 were found to have used their smart phones.
180/400 = 0.45
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
Answer:

Step-by-step explanation:
Let
x ----> the number of tickets
y ----> the price of tickets
we have the ordered pairs
(4,63) and (6,92)
step 1
<em>Find the slope of the linear equation</em>
The formula to calculate the slope between two points is equal to

substitute the values


step 2
Find the y-intercept or initial value of the linear equation
we know that
The linear equation in slope intercept form is equal to

where
m is the slope b is the y-intercept
we have


substitute

solve for b


In this context the y-intercept is a one charge fee for the ticket service
The equation is equal to
