Ashley, Bob, Claire, and Daniel are among 13 students who entered a lottery to win a free vacation to Paris.

AlladinOne [14]

Answer:

0.0014 = 0.14% probability that Ashley, Bob, Claire, and Daniel will be chosen.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the students are chosen is not important, so the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

4 students from a set of 4(Ashley, Bob, Claire, and Daniel). So

$D = C_{4,4} = \frac{4!}{4!(4-4)!} = 1$

Total outcomes:

4 students from a set of 13(number of students in the lottery). So

$T = C_{13,4} = \frac{13!}{4!(13-4)!} = 715$

Probability:

$p = \frac{D}{T} = \frac{1}{715} = 0.0014$

0.0014 = 0.14% probability that Ashley, Bob, Claire, and Daniel will be chosen.

The equation for the volume of a pyramid is (l*w*h)/3

since the problem gave you the base area, that would be the l *w

so now you would need to multiply the base area by the height, then divide by 3

16 * 15 = 240

240/ = 80 cubic centimeters

Given:

Cost of fish dinner = $10.95

selling price of fish dinner = $13.95.

To find:

The percent markup.

Solution:

We know that,

$\text{Percent Markup}=\dfrac{\text{Price - Cost}}{\text{Cost}}\times 100$

Using this formula, we get

$\text{Percent Markup}=\dfrac{13.95-10.95}{10.95}\times 100$

$\text{Percent Markup}=\dfrac{3}{10.95}\times 100$

$\text{Percent Markup}=\dfrac{300}{10.95}$

$\text{Percent Markup}=27.39726$

Round to the one decimal place.

$\text{Percent Markup}\approx 27.4$

Therefore, the markup is 27.4%.
