Original equation is 
So,
and

If we compare this equation with the given options, we can easily find that this matches with the last one
with P = p/2.
Hence, correct option is
.
Did you ever get the answer?
Answer: a. You must pay $11.19 for the item.
b.The price you would expect to pay would be $36.59
Step-by-step explanation:
Hi, for first the question you need to calculate the 30 percent of the price of the item, and then subtract that result to the original price.
So: $15.99 × 0,30 = $4.797
$15.99 - $4.797 = $11.19
You must pay $11.19 for the item.
It´s a similar resolution, first you calculate the 40 percent of the retail price, and then subtract that result to the retail price.
So:
$60.99 × 0,40= $24.396
$60.99 - $24.396 = $36.59
The price you would expect to pay would be $36.59
Answer:
Our population of interest represent all the adults in United states who never travel using commercial airlines.
The sample on this case represent the people surveyed in United States who never travel using commercial airlines.
For this case the value obtained
represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by 
Step-by-step explanation:
A statistic is a "characteristic of a sample". And the statistic allows "estimate the value of a population parameter".
A parameter is a value who represent the population of interest.
For this case we have a sample size of size n = 2276
The proportion estimated
of people that nevel travel using commercial airlines was:
or 33%
Our population of interest represent all the adults in United states who never travel using commercial airlines.
The sample on this case represent the people surveyed in United States who never travel using commercial airlines.
For this case the value obtained
represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by 
2pi radians=360 degrees
rato and proprtion
xrad/(2pi)=ydeg/360
xrad/2pi=82/360
times both sides by 2pi
xrad=164pi/360
xrad=41pi/90
aprox pi=3.141592
xrad=1.431
round
xrad=1.43 radians
1.43 radians=82 degrees
