Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

[tex]x+y=72[/tex]

We know that Jason has three more than four times the amount of money Jeff has. So:

[tex]x=3+4y[/tex]

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

[tex](3+4y)+y=72[/tex]

Combine like terms:

[tex]5y+3=72[/tex]

Subtract 3 from both sides:

[tex]5y=69[/tex]

Divide both sides by 5:

[tex]y=69/5=\$13.80[/tex]

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

[tex]x=13.8(4)+3[/tex]

Multiply and add:

[tex]x=\$58.20[/tex]

So, Jason has $58.20 and Jeff has $13.80.

And we're done!

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.

Answer: 30

Step-by-step explanation:

Thos is simply 6*10/2 which is 30.

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.

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! :)

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

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.

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
