1. 35.
2. 49.
3. 41.
Given :
There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both.
38 have swim suits on and 25 have sunglasses.
To Find :
How many people had swim suits on but not sunglasses.
Solution :
Let, A refer swim suits and B refer sunglasses.
∞∪∩
A ∪ B = 50
A = 38
B = 25
We need to find, A - (A ∩ B) .
We know,
(A ∩ B) = A + B - (A ∪ B)
(A ∩ B) = 38 + 25 - 50
(A ∩ B) = 13
So, A - (A ∩ B) = 38 - 13 = 25
Therefore, number of people with swim suits on but not sunglasses are 25.

what is the value of f(g(-3)?
Answer:
f(x) + g(x) = (-2x + 8)+ 3x
f(x) + g(x) = -2x + 8 + 3x Combine like terms.
f(x) + g(x) = x + 8
f(x) + g(x) = (f+g)(x) = x + 8

If an items costs $41.04, including an 8% sales tax, what was the cost of
the item before taxes?
Answer:
$38
Step-by-step explanation:
I solved this by doing a proportion, 41.04/108 = x/100 to find the original price before the 8% tax. To solve this proportion you have to isolate the variable, so you would do the cross product and multiply (41.04 x 100) and have that equal to 108x. So then because you have 108x = 4104, isolate x by dividing by 108 and you get 38, thus $38.
You can also check your work by multiplying 38 by 0.08 to find the amount of sales tax added, and if you do this you will get the value $41.04.
A percentage is a number or ratio that represents a fraction of 100.
If an item costs $41.04, including an 8% sales tax then the cost of the item before the tax is $37.76.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50/100 = 1/2
20% = 20/100 = 1/5
25% = 25/100 = 1/4
10% = 10/100 = 1/10
5% = 5/100 = 1/20
We have,
Cost of an item including tax = $41.04
Sales tax = 8%
8% = 8/100
The cost of the item without the sales tax:
= 41.04 - (8% of 41.04)
= 41.04 - (8/100 x 41.04)
= 41.04 - 3.2832
= 37.76
Thus,
The cost of the item before the tax is $37.76.

A popular podcast poses questions to subscribers at the end of each segment, asking listeners to enter their
responses on a website to join the sample. One of the questions was: "Do you regularly read nonfiction novels?" More
than 45,000 people responded, with 59 percent saying "Yes." Which of the following is true?
A) The sample is too small to draw any conclusion.
B) About 59% of people in the US regularly read nonfiction novels.
C) The poll uses voluntary response, so the results tell us little about the population of all adults.
D) The poll uses a convenience sample, so the results tell us little about the population of all adults.
E) The poll suffers from nonresponse bias, so the results tell us little about the population of all adults.
Answer:
The poll uses voluntary response, so the results tell us little about the population of all adults.
Step-by-step explanation:
I took the test
The one which is true would be; C poll uses voluntary response, so the results tell us little about the population of all adults.
How to calculate confidence interval for population mean for small sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
Let the sample mean given as [tex]\overline{x}[/tex] and
The sample standard deviation s, and
The sample size = n, and
The level of significance = [tex]\alpha[/tex]
About 59% of the 45,000 people responded as "Yes" to the question
The sample size is n = 45,000.
The sample proportion is p = 0.59.
The sample selected is a voluntary sample, such that the individuals provided their responses voluntarily. So, the sample is not a true representative of the population.
Thus the results tell us little about the population of all adults because of the large sample size.
The correct option is C poll uses voluntary response, so the results tell us little about the population of all adults.

You are a salesperson and your provability of selling items is 2 out of 20. (probability of success). if you have 4 potential customers, what is the probability that you are going to sell to exact 2 of these customers
Answer:
P(X = 2) = 0.0486
Step-by-step explanation:
We are told that probability of selling items is 2 out of 20.
Thus, probability of success is;
p = 2/20 = 0.1
you have 4 potential customers and you want to find the probability that you are going to sell to exact 2 of these customers.
This is a binomial probability distribution problem.
Thus;
n = 4 and x = 2.
So;
P(X = 2) = C(4, 2) × 0.1^(2) × (1 - 0.1)^(4 - 2)
P(X = 2) = 6 × 0.01 × 0.81
P(X = 2) = 0.0486

Suppose that you draw one card from a well-shuffled deck of 52 playing cards. What is the probability that the card that you draw is a black 7 or a black 8
The probability that the card that you draw is a black 7 or a black 8 is 1/13
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
So, the probability that the card that you draw is a black 7 = 4/52
So, the probability that the card that you draw is a black 8 = 2/26
Therefore,
the probability that the card that you draw is a black 7 or a black 8 = 4/52 - 2/26 = 1/13
