If item costs $99.99 with 15% off and I get final price. It then asks me what percentage of savings. How do I get the percentage of savings

Answers

Answer 1

Answer: ok.. if you got 84.99 as you answer then you would put .15 *99.99 then you would get 14.9985 then round and get 15.00 and then 99.99 - 15.00 ....you will get 84.99...i think

Answer 2

2. Which of the following is true of functions and their inverses?A. The inverse of a quadratic function is not a function.
B. The inverse of a linear function is always a function.
C. The inverse of a quadratic function is always a function.
D. The inverse of a linear function is not a function.

Answers

Answer – A. (The inverse of a quadratic function is not a function)
Since a parabola (quadratic function) does not pass the horizontal line test, it is not possible for a quadratic equation to will have an inverse that is also a function.

Option B is wrong because the inverse of a linear function is not always a function because when the linear function has slope, the inverse cannot be a function.
Option C is wrong because the inverse of a quadratic function is never a function because a quadratic function does not pass the horizontal line test
Option D is wrong because the inverse of a linear function is a function, provided that the linear function has no slope.

The correct answer is:

A) The inverse of a quadratic function is not a function.

Explanation:

The inverse of a function is a function if and only if each element of the range (y-coordinates) is mapped to one element of the domain (x-coordinates).

Each y must be mapped to one x; this means no y can be repeated. This means if we draw a horizontal line through any part of the graph of an inverse function, it should not hit more than 1 point.

The graph of a quadratic function is a parabola, or a u-shaped graph. If we draw a horizontal line through a parabola, it will hit twice everywhere except the vertex. This means the inverse of a quadratic function is not itself a function.

Find the mean of the numbers 10, 11, 12, 14, 12, 11, 13, 12, 14, and 11.

Answers

Answer:

mean = 12

Step-by-step explanation:

the mean of a data set is calculated as

mean = $(sum)/(count)$

sum = 10 + 11 + 12 + 14 + 12 + 11 + 13 + 12 + 14 + 11 = 120

there are 10 values, so count = 10

Then

mean = $(120)/(10)$ = 12

If a field researcher wanted to learn a political organization's pattern of recruitment over time, the researcher mightbegin by interviewing a fairly recent recruit and ask who introduced that person to the organization. Then theresearcher might interview the person named and ask who introduced that person to the political organization.This would be an example of: systematic sampling. accidental sampling. snowball sampling. quota sampling deviant cases sampling.

Answers

Answer:

C. snowball sampling

Step-by-step explanation:

Snowball sampling also known as referral sampling or chain sampling is a sampling method in research where the participants in the research are recruited to find new participants. This is a non-probability sampling method because participants choose other participants through their own insight. Just as a ball takes up more snow as it rolls by, so also this research method takes up more participants as it progresses.

So, when the field researcher who wanted to learn about a political organization's recruiting pattern begins by interviewing a participant who in turn suggests another participant, he has applied the snowball sampling method.
