Answer: C

Step-by-step explanation: In this problem, we're given a function

in the form of a chart and we're asked to find the inverse of the function.

To find the inverse of a function, we simply switch

the x and y values in each point.

In other words, the point (-1, -2) becomes (-2, -1),

the point (0, 3) becomes (3, 0), the point (1, 8) becomes (8, 1),

and the point (2, 13) becomes (13, 2).

$27 \times \frac{2}{3}=9 \times 2=18$

Charles has 18 books.
Jim has three times as many books as Charles.

$18 \times 3=54$

Sue Ellen sews quilts. She charges $45 for fabric and sewing supplies and $20 for each hour,

mars1129 [50]

Answer:

D: 20h + 45 = 165

Step-by-step explanation:

20 for EACH hour means that there's a variable (h) attached to 20 so it has to be 20h

Because of that, we can eliminate choices A and B.

Charges mean that it's ADDED to the price so it has to be 45 PLUS 20h

20h + 45 = 165

After a political ad campaign, pollsters check the president's negatives. They test the hypothesis that the ads produced no chan

blsea [12.9K]

Answer:

C- There is a 3.8% chance that natural sampling variation could produce poll results at least as far below 54% as these if there is really no change in public opinion.

Step-by-step explanation:

The p-value indicates the probability that the test statistic occurs, given that the parameters of the null hypothesis are true.

The smallest the p-value, the less likely is the sample statistic obtained. If this p-value is below a threshold, called "level of significance", it can be claimed that the null hypothesis is wrong.

In this case, we can not say anything about the probability of success of the ad campaign or the quality of the poll, because we have no information about it.

a bag contains 2 coins, one fair and the other with 2 heads. you pick 1 coin at random and flip it. what is the probability that

Nezavi [6.7K]

The probability that you picked the fair coin given that the outcome of the toss was heads is 1/3.

There is a one in two chance of drawing the fair coin. The chances of flipping heads again are 1 in 2. As a result, there is a 1 in 4 chance that the coin will land on heads.

There is a one in two chance of drawing the trick coin. The probability of flipping heads is then 2 to 1. As a result, there is a 2 in 4 chance that the coin will land on heads.

When each is multiplied by four, the resulting integers are

fair: 1 and trick: 2

and overall results: 3. (fair and tails is not counted)

The likelihood of a fair coin is one in three.

The likelihood that the chosen coin will show heads and be the fair coin is 33.333%.
