Step-by-step explanation:
One out of every 119 tax returns that a tax auditor examines requires an audit. Find the probability that (a) the first return requiring an audit is the 25th return the tax auditor examines, (b) the first return requiring an audit is the first or second return the tax auditor examines, and (c) none of the first five returns the tax auditor examines require an audit.
Answer:
A) 0.00686
B) 0.01673
C) 0.99587
Step-by-step explanation:
For this question, we are interested in the first success and we will Thus make use of geometric probability distribution.
It goes by the formula;
P(x) = [(1 - p)^(x - 1)]p
We are told that One out of every 119 tax returns that a tax auditor examines requires an audit.
Thus; p = 1/119 = 0.0084
A) Probability that the first return requiring an audit is the 25th return the tax auditor examines is given by;
P(25) = [(1 - 0.0084)^(25 - 1)]0.0084
P(25) = 0.00686
B) Probability the first requiring an audit is the first or second return the tax auditor examines, is;
P(1 or 2) = P(1) + P(2)
P(1) = [(1 - 0.0084)^(1 - 1)]0.0084
P(1) = 0.0084
P(2) = [(1 - 0.0084)^(2 - 1)]0.0084
P(2) = 0.00833
Thus;
P(1 or 2) = 0.0084 + 0.00833
P(1 or 2) = 0.01673
C) Probability that none of the first five returns the tax auditor examines require an audit is given by;
P(X > 5) = 1 - P(X ≤ 5)
Now,
P(X ≤ 5) is expressed as;
P(X ≤ 5) = P(1) + P(2) + P(3) + P(4) + P(5)
We know P(1) & P(2) already. Let's find P(3), P(4) and P(5)
P(3) = [(1 - 0.0084)^(3 - 1)]0.0084
P(3) = 0.00826
P(4) = [(1 - 0.0084)^(4 - 1)]0.0084
P(4) = 0.00819
P(5) = [(1 - 0.0084)^(5 - 1)]0.0084
P(5) = 0.00812
P(X ≤ 5) = 0.0084 + 0.00833 + 0.00826 + 0.00819 + 0.00812
P(X ≤ 5) = 0.00413
P(X > 5) = 1 - 0.00413
P(X > 5) = 0.99587

What is the formula for distance?
Formula:
Hope this helped, if not, don’t spam.
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving a sample problem using the distance formula.
Sample problem: Determine the distance between P(3, 2) and Q(10, 2).
From inspection on the given problem:
(x_1, y_1) = (3, 2)(x_2, y_2) = (10, 2)Substitute the given values into the distance formula and solve for PQ:
[tex]\sf PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf PQ = \sqrt{(10 - 3)^2 + (2 - 2)^2}[/tex][tex]\sf PQ = \sqrt{(7)^2 + (0)^2}[/tex][tex]\sf PQ = \sqrt{49 + 0}[/tex][tex]\sf PQ = \sqrt{49}[/tex][tex]\bold{PQ = 7 \: units}[/tex]Therefore, the distance between two points is 7 units.

Write a formula that will help Greg determine
how much money he will earn in one week.
Let's let
a = total amount earned
h = hours worked in one week
b = number of bushels picked
Use the curved parentheses 'O', if required.
Do not use other parentheses like '{ }' or '[ ]'.
Answer:
a = 3h + 2.50b
Step-by-step explanation:
Greg picks apples to make money over the summer. He earns $3 an hour plus $2.50 for each bushel he picks. Write a formula that will help Greg determine how much money he will earn in one week.
Let
a = Total amount earned
h = Hours worked in one week
b = Number of bushels picked
Solution:
Amount earned per hour = $3
Amount earned per bushel picked = $2.50
Total amount earned = (Amount earned per hour) ( Hours worked in one week) + (Amount earned per bushel picked) (Number of bushels picked)
a = 3*h + 2.50*b
= 3h + 2.50b
a = 3h + 2.50b
Simplify the expression 256b − b by combining like terms.
Answer:
255b
Step-by-step explanation:
subtract 256b by b

C.(−0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x=0.
D.(−0.5, 3) and (0.5, 1) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the opposite of the slope of the function at x=0.
Answer:
2. B. The rate of change is 2
3. C. The rate of change is 2 inches per hour
4. B. The rate of change is 1.25 degrees Fahrenheit per day
5. (-0.5, 3) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0
Step-by-step explanation:
2. Using the points (-1, -1) and the (1, 3) we have;
The rate of change = (Change in the y-values)/(Corresponding change in the x-values)
The rate of change = (3 - (-1))/(1 - (-1)) = 4/2 = 2
The rate of change is 2
3. Using the points (0, 0) and the (5, 10) we have;
The rate of change = (Change in the y-values)/(Corresponding change in the x-values)
Given that the function is a linear function, the rate of change of the function at 3 hours is given by the slope, m, as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (0, 0)
(x₂, y₂) = (5, 10)
The y-coordinate being the inches of snow, and the x-coordinate being the time in hours, we have;
The rate of change = (10 - 0)/(5 - 0) = 10/5 = 2
The rate of change is 2 inches per hour
4. Given that the function is a linear function, the rate of change of the function at ninth day is given by the slope, m, as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (2, 55)
(x₂, y₂) = (10, 65)
The y-coordinate being the temperature in degrees, and the x-coordinate being the time in days, we have;
[tex]Slope, \, m =\dfrac{65-55}{10-2} = \dfrac{10}{8} = 1.25[/tex]
The rate of change is 1.25 degrees Fahrenheit per day
5. The points on the graph of the function that come before and after the point where the graph of the function crosses y-axis (the y-intercept) and are close to point are (-0.5, 2) and (0.5, 3)
Therefore, (-0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0.

Question 4 (1 point) Phil Dunphy, a real estate agent, is considering whether he should list an unusual $345,584 house for sale. If he lists it, he will need to spend $5,892 in advertising, staging, and fresh cookies. The current owner has given Phil 6 months to sell the house. If he sells it, he will receive a commission of $19,166. If he is unable to sell the house, he will lose the listing and his expenses. Phil estimates the probability of selling this house in 6 months to be 33%. What is the expected profit on this listing? Your Answer:
Answers:
The expected profit on the listing is $2377.14
Step-by-step explanation:
Given that:
The probability of selling the house in 6 months is p = 0.33
The probability of not selling the house = 1 - 0.33 = 0.67
Suppose X represents the profit on the listing;
Then: we can compute the expected profit on the listing as:
E(X) = ($19166 × 0.33) - ($5892 × 0.67)
E(X) = $6324.78 - $3947.64
E(X) = $2377.14
Thus, the expected profit on the listing is $2377.14
I need to know if there functions or not (algebra)
Answer:
Number 14 is a function and Number 16 is NOT a function.
Step-by-step explanation:
To check if a set of numbers form a function, you can look at the x values or the imput values.
For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.
For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.
Also note, the y values are called the outputs.
A function is only allowed to have ONE imput with each output.
Hope this helps! :)

Maggie plans to sell the bracelets she makes for a price of $5.50 each. For every bracelet she makes, she has costs of $0.05 for each of the 21 beads used, $0.74 for each of the two charms used, and $1.09 for the chain with clasp used. Which of these would result in Maggie NOT earning a profit on the sale of a bracelet?
Price of each bracelets , P = $5.50 .
Cost price = $0.05 for each of the 21 beads used + $0.74 for each of the two charms used + $1.09 for the chain with clasp used.
Cost price = $( 0.05×21 + 0.74×2 + 1.09 )
Cost price = $3.62 .
Now, profit is given by :
Profit = Selling price - Cost price
Profit = $(5.50 - 3.62)
Profit = $1.88
Therefore, she will not bear any loss.

Advertisers contract with Internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unfortunately click fraud, the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue, has become a problem. Forty percent of advertisers claim they have been a victim of click fraud. Suppose a random sample of 380 advertisers will be taken to learn more about how they are affected. What is the probability that the sample proportion will be with 0.04 of the population proportion?
Answer:
The probability that the sample proportion will be with 0.04 of the population proportion is 0.8904.
Step-by-step explanation:
Let p = proportion of advertisers who claim they have been a victim of click fraud.
The population proportion is, p = 0.40.
A random sample of 380 advertisers is selected.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
[tex]\mu_{\hat p}=p[/tex]
The standard deviation of this sampling distribution of sample proportion is:
[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]
The sample selected is too large, i.e. n = 380 > 30.
Then the proportion of advertisers who claim they have been a victim of click fraud can be approximated by the normal distribution.
The mean and standard deviation of this sampling distribution of sample proportion is:
[tex]\mu_{\hat p}=p=0.40\\\\\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.40(1-0.40)}{380}}=0.025[/tex]
Compute the probability that the sample proportion will be with 0.04 of the population proportion as follows:
[tex]P(p-0.04<\hat p<p+0.04)=P(\frac{-0.04}{0.025}<\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.04}{0.025})[/tex]
[tex]=P(-1.60<Z<1.60)\\=P(Z<1.60)-P(Z<-1.60)\\=0.94520-0.05480\\=0.8904[/tex]
Thus, the probability that the sample proportion will be with 0.04 of the population proportion is 0.8904.
