The area of a rectangular living room is 192 square feet. The length of the room is 8 feet less than twice the width. What is the width of the living room in feet?

Answers

Answer 1

Answer:

The width of the living room is 10 feet.

Step-by-step explanation:

Let the width of the living room is w.

And the length of the room is 2w - 8 ft.

Given,

The area of the room is 192  feet^2, by using the formula of area of a rectangle we get,

A = l × w

192 = (2w - 8) × w

Now,

192 = 2w^2 - 8w                              ( By expanding)

200 = 2w^2                                     (By adding 8w to both sides)

100 = w^2                                        (Dividing both sides by 2)      

If we take square root on both sides,

w = 10

So,

The width of the living room is 10 feet.

Three vertices of a parallelogram are located at (-4, 3), (1, -2), and (-1, 4). What are
two possible locations of the fourth vertex? Explain your reasoning.

Answers

The two possible locations of the fourth vertex are (4, -1) and (-6, 9). The solution has been obtained by using the properties of parallelogram.

What is a parallelogram?

A parallelogram has two sets of parallel sides, making it a quadrilateral. A parallelogram's opposing sides and angles are both the same length.

Finding the vector that depicts the shift from one of the given vertices to another is necessary in order to determine the fourth vertex of a parallelogram.

The third given vertex must then be added to the vector.

We know that the opposite sides of a parallelogram are parallel and equal in length, we may determine the coordinates of the other two vertices by adding the same displacement vector to two of the given vertices.

The difference between the first and second provided vertices i.e.

(1 - (-4), -2 - 3), is one potential displacement vector which is (5, -5).

On adding this vector to the third vertex, we get the fourth vertex as (4,-1).

Similarly, the difference between the second and third vertices i.e.

(-1 - 1, 4 - (-2))  is another potential displacement vector which is (-2, 6).

On adding this vector to the third vertex, we get the fourth vertex as

(-6, 9).

Hence, the two possible locations of the fourth vertex are (4, -1) and

(-6, 9).

Year driven = third

Miles driven = 10,000

The depreciation for this vehicle using method 2 will be $

Answers

The depreciation of the vehicle at third year with miles driven 10,000 is $590.

What is depreciation cost?

A fixed asset's depreciated cost is equal to its value less the total amount of accumulated depreciation that has been recorded against it.

The depreciated cost is used to calculate an asset's value after its useful life is over.

The depreciated cost helps organizations examine their capital spending patterns and their accounting technique.

The depreciated cost is also known as the "residual value," "net book value," or "changed cost base."

The depreciation cost per mile for the third year is given as 5.9 cents.

The miles driven = 10,000

The depreciation for the vehicle is:

(5.9)(10,000) = 59000 cents.

Converting into dollars:

59000/100 = $590.

Hence, the depreciation of the vehicle at third year with miles driven 10,000 is $590.

Step-by-step explanation:

From the image below you can see that

90 F  + 60 L   = 160 miles

and given F + L = 2 hours       re arrange to  F = 2 - L  

                                      and substitute this "F" into the first equation

90 (2-L )  + 60 L = 160           Solve for L

180  - 90 L     + 60 L     = 160

180 - 30 L = 160

In a regression equation (linear prediction rule), the "predicted score" for a person with a "predictor variable" score of 0 is 7. In this scenario, what is the "regression constant"?

Answers

The required value of  "regression constant" is 7.

What is regression equation?

Y = a + b X + e is the formula for the regression equation. The dependent variable (Y), which is being predicted or explained, has a value of Y. a, or Alpha, is a constant; it equals the value of Y when the value of X is 0, and b, or Beta, is a coefficient of X; it determines how much Y varies for each unit change in X and determines the slope of the regression line.

According o question:

In a linear regression equation, the regression constant (also called the intercept) represents the predicted score when the predictor variable has a value of 0. In this scenario, the predicted score for a person with a predictor variable score of 0 is 7.

Therefore, the regression constant is 7.

The regression constant is usually combined with the regression coefficient of the predictor variable to form the complete regression equation, which is used to predict scores for individuals with different values of the predictor variable.

The nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 9 grams of dietary fiber. At that rate, find how many calories and grams of fiber are in a 2/3-cup serving.

Answers

Answer:

Step-by-step explanation:

To find the number of calories and grams of fiber in a 2/3-cup serving, we can simply multiply the values for a 1/2-cup serving by the appropriate factor. A 2/3-cup serving is 1.5 times larger than a 1/2-cup serving, so we multiply the calorie and fiber content by 1.5.

210 calories * 1.5 = 315 calories

9 grams of fiber * 1.5 = 13.5 grams of fiber

So a 2/3-cup serving would contain 315 calories and 13.5 grams of fiber.

Answers

The average thickness of the metal sheet is 0.0423 inches.

What do you mean by average?

In statistics, the mean is a measure of central tendency of a set of data. It is also referred to as the arithmetic mean and is calculated by adding up all the values in the data set and dividing by the total number of values.

Mean = (sum of all values) / (number of values)

For example, suppose we have the following set of data: 5, 7, 9, 11, 13. To find the mean, we add up all the values and divide by the total number of values, which is 5 in this case:

Mean = (5 + 7 + 9 + 11 + 13) / 5

Mean = 9

Therefore, the mean of this data set is 9.

The mean is a commonly used measure of central tendency because it takes into account all the values in the data set and is sensitive to changes in the data. However, it can be affected by outliers or extreme values in the data set, which can skew the results.

To find the average thickness of the sheet, we need to add the five measurements together and then divide by 5 (the number of measurements):

Average thickness = (0.0401 + 0.0417 + 0.0462 + 0.0407 + 0.0428) / 5

Average thickness = 0.0423 in

Therefore, the average thickness of the metal sheet is 0.0423 inches.

Answers

When we are given the value of the explanatory variable, we can use the least-squares regression line to predict the value of the outcome variable.

The least square method is the process of finding the best-fitting curve or line of best fit for a set of data points by reducing the sum of the squares of the offsets (residual part) of the points from the curve. During the process of finding the relation between two variables, the trend of outcomes is estimated quantitatively. This process is termed as regression analysis. The method of curve fitting is an approach to regression analysis. This method of fitting equations that approximates the curves to give raw data is the least squares.

It is quite obvious that the fitting of curves for a particular data set is not always unique. Thus, it is required to find a curve having a minimal deviation from all the measured data points. This is known as the best-fitting curve and is found by using the least-squares method.
