Answer:
D. $16.42
Step-by-step explanation:
In order to find the sales tax of a product, you need to multiply the product's price by the sales tax in decimal form.
To find the decimal form of a percentage, you simply move the decimal paint two spaces to the left. So, 8.25% in decimal form is 0.0825.
199.99 * 0.0825 = 16.499175
This number is closest to $16.42, so D is the correct answer.
Considering the given discrete probability distribution, it is found that the expected share is of 10%.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution is given by:
Hence the expected value is given by:
E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.
The expected share is of 10%.

Answer:
12 students.
Step-by-step explanation:
The complete question would be:
If ice cream is the last dessert, then we can solve for how many percent of the students like ice cream. If we add the 4 desserts percent, it should be equal to 100%
Pie : 15%
Candy : 23%
Cake : 27%
Pie% + Candy% + cake% + ice cream% = 100%
15% + 23% + 27% + Ice cream% = 100%
65% + Ice cream% = 100%
Ice cream% = 100% - 65%
Ice cream % = 35%
Percent is a way of saying how many out of a 100. Before we can tell how many students like pie, we need to figure out how many students were surveyed.
It says here that 35% of them like ice cream and among the students, 28 students like ice cream. This means that 28 is 35% of a number, which will be the number of students surveyed.
So as a fraction:

We need to find a ratio that is proportional to that, with 28 as the part of the whole.

So that is the number of students survey. Now to look for how may people like pie, we find what is 15% of 80. So we find the part of the whole this time:
