A line contains points M(1, 3) and N(5, 0). What is the slope of MN?
The slope of the line that points M and N lies on is [tex]-\frac{3}{4}[/tex]
Given:
[tex]M(1, 3)\\N(5, 0)[/tex]
Formula for slope of a line is:
[tex]slope (m) = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let,
[tex]M(1, 3) = (x_1, y_1)\\N(5, 0) = (x_2, y_2)[/tex]
Substitute
[tex]Slope(m) = \frac{0-3}{5-1} \\= \frac{-3}{4} \\= -\frac{3}{4}[/tex]
Therefore, the slope of the line that contains M(1, 3) and N(5, 0) is: [tex]-\frac{3}{4}[/tex]

mike purchased two blankets at $44.99 each, one mattress for $59.00 and a sheet for $19.99. The sales tax rate is 5.75%. what is the total purchase price, including sales tax?
The total purchase price, including sales tax, for the two blankets, one mattress, and one sheet that Mike purchased is $178.69.
Explanation:To work out the total purchase price, including sales tax, for the items Mike purchased, first, we need to calculate the total cost of the blankets, mattress, and sheet before tax:
Two blankets: 2 × $44.99 each = $89.98One mattress: $59.00One sheet: $19.99Add these amounts together to find the subtotal:
$89.98 + $59.00 + $19.99 = $168.97
Next, we compute the sales tax. Convert the percent to a decimal by moving the decimal point two places to the left (5.75% becomes 0.0575), and then multiply by the subtotal:
0.0575 × $168.97 = $9.7161
Round the sales tax to the nearest cent: $9.72
Finally, add the sales tax to the subtotal to get the total purchase price:
$168.97 + $9.72 = $178.69
Therefore, the total purchase price, including sales tax, is $178.69.

The circumference of a circle is 28 pi inches. What is the length of the radius of this circle?
Answer:
The length of the radius of this circle is 14 inches.
Step-by-step explanation:
Circumference of the circle = [tex]28\pi[/tex]
Let's take the length of the radius of the circle as [tex]a[/tex]
Circumference of a circle = [tex]2\pi r[/tex]
Where,
r is the radius of the circle.
Therefore,
[tex]2\pi a=28\pi[/tex]
[tex]2a=28[/tex]
[tex]a=14[/tex]
Therefore, the length of the radius of this circle is 14 inches.

Solve the equation by factoring. z2 − 6z − 27 = 0
To solve the quadratic equation z² -6z - 27 = 0, factor it to get (z - 9)(z + 3) = 0. Using the Zero Product Property, we find that the solutions are z = 9 and z = -3.
Solving Quadratic Equations by Factoring
To solve the quadratic equation z ²
- 6z - 27 = 0 by factoring, we must find two numbers that add up to -6 and
multiply to -27. After identifying these numbers, we can factor the quadratic expression
into a product of two binomials and then apply the Zero Product Property to find the
values of z.
The two numbers that meet these criteria are -9 and 3, as (-9)*(3) = -27 and (-9)+(3) =
-6. Therefore, we can express the quadratic equation as:
(z - 9)(z + 3) = 0
By the Zero Product Property, we find the solutions to the equation by setting each
binomial equal to zero:
z - 9 = 0
z = 9
z + 3 = 0
z = -3
Thus, the solutions to the quadratic equation are z = 9 and z = -3. These are the z-values that satisfy the original equation.
A laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 199 milligrams with s = 16.5 milligrams. Construct a 95% confidence interval for the true mean cholesterol content of all such eggs.
To construct a 95% confidence interval, use the formula: Confidence Interval = sample mean ± (critical value * (sample standard deviation / sqrt(sample size))). The confidence interval for the true mean cholesterol content is approximately 190.37 to 207.63 milligrams.
Explanation:To construct a 95% confidence interval for the true mean cholesterol content of all chicken eggs, we can use the formula:
Confidence Interval = sample mean ± (critical value * (sample standard deviation / sqrt(sample size)))
Given that the sample mean is 199 milligrams, the sample standard deviation is 16.5 milligrams, and the sample size is 12, we need to determine the critical value for a 95% confidence level. Since we have a small sample size, we need to use the t-distribution.
Using a t-table or a statistical calculator, we find that the critical value for a 95% confidence level with a sample size of 12 is approximately 2.179.
Substituting the values into the formula, we get:
Confidence Interval = 199 ± (2.179 * (16.5 / sqrt(12)))
Simplifying and calculating, the confidence interval is approximately 190.37 to 207.63 milligrams.
To construct a 95% confidence interval for the mean cholesterol content of chicken eggs, we use the sample data provided, along with the t-distribution for a sample size less than 30, and apply the standard formula for confidence intervals.
Explanation:The question asks to construct a 95% confidence interval for the true mean cholesterol content of chicken eggs based on the given sample data. To calculate this, we first need to use the sample mean (μ), which is 199 milligrams, and the standard deviation (s), which is 16.5 milligrams. Since the sample size is less than 30, we will use the t-distribution to find the critical value. With n=12, the degrees of freedom (df) are 11.
First, look up the critical t-value for df=11 at a 95% confidence level. Let's assume it is approximately 2.201. Next, calculate the standard error (SE) of the mean by dividing the sample standard deviation by the square root of the sample size. That's SE = 16.5 / sqrt(12).
Now, we can construct the confidence interval using the formula: mean ± (t-value * SE). Plugging in the numbers, we get 199 ± (2.201 * SE).
d. A 95 percent confidence interval means that if we took many samples and built a confidence interval from each of them, we'd expect about 95 percent of those intervals to contain the true mean cholesterol level of all such eggs. Because of sample variability, the interval provides a range of values within which we are 95% confident the true mean lies.
