Answer:

5xy(2x - 3y)

Step-by-step explanation:

The greatest common factor (GCF) of two or more numbers is the largest number that is a factor of all of them.

2*5*x*x*y-3*5*x*y*y

The greatest common factor is 5*x*y. So, we can factor out 5xy to get:

5xy(2x - 3y)

This is the factored expression.

Answer:

m = -1/3

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Write equation

x + 3y = 10

Step 2: Convert to slope-intercept form

3y = 10 - x

y = 10/3 - x/3

We see that our slope would be the term -1/3x. Since m is the coefficient of x and our slope, our slope m = -1/3

Answer:

- 1/3x

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

x + 3y = 10        Equation

Step 3:

3y = 10 - x     Subtract x on both sides

Step 4:

y = 10/3 - 3/x      Divide 3 on both sides

Step 5:

y = 10/3 - 1/3x     Simplify

Answer:

Slope = - 1/3x

Answer:

You would run 12 laps.

Step-by-step explanation:

4 laps = mile because...

4x[tex]\frac{1}{4}[/tex]=1

If 4 laps are one mile, multiply 3 times 4 because you want a 3-mile workout...

3x4=12.

Hope this helps you out!! Have an amazing day :)

12 laps would have to run for a 3-mile workout.

Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities

Now it is given that,

Each lap around a track is 1/4 mile

Therefore,number of laps in 1 mile = 4 laps

Now to run for a 3 mile work out multiply each mile with a lap to get the required workout.

Therefore,

3-mile workout = number of laps in 1 mile*number of mile workout

⇒ 3-mile workout = 4*3 laps

⇒ 3-mile workout = 12 laps

Thus,12 laps would have to run for a 3-mile workout.

The probability that the average NOX + NMOG level of these cars is above 91 mg/mi is 0.0000.

To find the probability that the average NOX + NMOG level of the 36 cars is above 91 mg/mi, we need to calculate the z-score and then find the corresponding probability using the standard normal distribution.

First, we calculate the standard error of the mean (SEM), which is the standard deviation divided by the square root of the sample size:

SEM = 5 / √36 = 5 / 6 = 0.8333

Next, we calculate the z-score using the formula:

z = (x - μ) / SEM

Where x is the desired value (91 mg/mi), μ is the mean (86 mg/mi), and SEM is the standard error of the mean.

z = (91 - 86) / 0.8333 = 6 / 0.8333 = 7.2003

Now, we can use a standard normal distribution table or calculator to find the probability corresponding to this z-score. The probability of the average NOX + NMOG level being above 91 mg/mi is the area under the curve to the right of the z-score.

Looking up the z-score in a standard normal distribution table, we find that the probability is approximately 0.0000.

Answer:

x = 36, Angles = 72, 108

Step-by-step explanation:

You have two parallel lines crossed by a perpendicular line. That means the value of [tex]2x + 3x = 180[/tex]°

As such we know that:

[tex]2x+3x=5x=180[/tex]°

So we divide by [tex]5[/tex] to get: [tex]180/5 = 36=x[/tex]

Therefore

[tex]x = 36\\2x = 72\\3x = 108[/tex]

And we know it makes sense because [tex]72 + 108 = 180[/tex].

Homoskedasticity and heteroskedasticity are terms used to describe the variability of errors in a multiple linear regression model.

To check for heteroskedasticity in a multiple linear regression model, there are several diagnostic tests and graphical methods that can be used: Residual plot, Breusch-Pagan test, White's test, Goldfeld-Quandt test,

Homoskedasticity refers to a situation where the variance of the errors (residuals) is constant across all levels of the independent variables. This means that the spread of the residuals is the same throughout the range of predicted values. In other words, the variability of the errors is consistent and does not change systematically.

Heteroskedasticity, on the other hand, occurs when the variance of the errors is not constant across all levels of the independent variables. In this case, the spread of the residuals tends to vary as the predicted values change. Heteroskedasticity implies that the variability of the errors is not consistent and may exhibit patterns or trends.

To check for heteroskedasticity in a multiple linear regression model, there are several diagnostic tests and graphical methods that can be used: Residual plot, Breusch-Pagan test, White's test, Goldfeld-Quandt test,

Residual plot: Plotting the residuals against the predicted values or the independent variables can reveal patterns or trends in the spread of the residuals. If the spread of the residuals appears to fan out or there is a clear pattern, it suggests the presence of heteroskedasticity.

Breusch-Pagan test: This is a statistical test that formally tests for heteroskedasticity in the residuals. The test assesses the relationship between the squared residuals and the independent variables. If the test result is statistically significant, it indicates the presence of heteroskedasticity.

White's test: Similar to the Breusch-Pagan test, White's test also examines the relationship between the squared residuals and the independent variables. It is another statistical test commonly used to detect heteroskedasticity in regression models.

Goldfeld-Quandt test: This test divides the data into two groups based on a selected independent variable and compares the variances of the residuals between the two groups. If the variances significantly differ, it suggests the presence of heteroskedasticity.

By conducting these tests and examining the graphical plots, one can assess whether heteroskedasticity is present in the multiple linear regression model. If heteroskedasticity is detected, it may be necessary to address the issue by using heteroskedasticity-robust standard errors, transforming variables, or considering alternative regression techniques designed to handle heteroskedastic data.

(a) To calculate the determinant of matrix A, we can use various methods such as cofactor expansion or row reduction. By using the cofactor expansion method along the first row, we have:

[tex]det(A) = 2 * det([2 -3; 0 -1]) - 1 * det([121 -3; 0 -1]) + 0 * det([121 2; 0 -1])= 2 * (2 * (-1) - (-3) * 0) - 1 * (121 * (-1) - (-3) * 0) + 0 * (121 * (-1) - 2 * 0)= 2 * 2 - 1 * (-121) + 0= 4 + 121= 125[/tex]

(b) We are given the determinant of matrix G as 17, which can be represented as [tex]|G| = |a b c; d e f; g h i| = 17[/tex]. By comparing the elements, we have [tex]3a + 36 + 3c + hi + g + d + 6a + 6b + 6c + e + 6f = 17[/tex].

We know that [tex]$$\frac{a}{b}$$[/tex]is equivalent to [tex]$$a \div b$$[/tex]which means division of a by b. Thus, the given expression is equivalent to$$-\frac{1}{2} \div (-12x + 30)$$Similarly,

multiplication by the reciprocal of the denominator yields the following equivalent expressions:[tex]$$-\frac{1}{2} \div (-12x + 30) = -\frac{1}{2} \c[/tex]dot [tex]\frac{1}{-12x + 30}$$$$=-\frac{1}{2(-12x + 30)}$$[/tex]Lastly, $$\frac{1}{a} \cdot b = \frac{b}{a}$$[tex]$$\frac{1}{a} \cdot b = \frac{b}{a}$$[/tex]

(a) The regular selling price of the watches is $330.

(b) The sale price for the store to break even is $330.

(c) The rate of markdown to sell the watches at the break-even price is 0%.

(a) To find the regular selling price of the watches, we need to consider the unit price the store paid for the shipment and apply the overhead and profit percentages.

The unit price the store paid is $250 less 40%, which can be calculated as:

Unit Price = $250 - (40/100) * $250

Unit Price = $250 - $100

Unit Price = $150

Now, we need to calculate the regular selling price by adding the overhead and profit percentages to the unit price.

Overhead = 65% of cost = (65/100) * $150 = $97.50

Normal profit = 55% of cost = (55/100) * $150 = $82.50

Regular Selling Price = Unit Price + Overhead + Normal Profit

Regular Selling Price = $150 + $97.50 + $82.50

Regular Selling Price = $330

Consequently, the timepieces' usual retail price is $330.

(b) To determine the sale price for the store to break even, we need to consider the cost of the watches, overhead, and normal profit percentages.

Break-even Price = Unit Price + Overhead + Normal Profit

Break-even Price = $150 + $97.50 + $82.50

Break-even Price = $330

Therefore, $330 should also be the sale price for the shop to break even.

(c) The rate of markdown to sell the watches at the break-even price can be calculated by finding the markdown percentage from the regular selling price.

Markdown = Regular Selling Price - Break-even Price

Markdown = $330 - $330

Markdown = $0

Since there is no markdown, the markdown rate required to sell the timepieces at a profit is 0%.
