What Is The Value Of X?

Answers

Answer 1

Answer:

x = 70

Step-by-step explanation:

The angles are same side interior angles and when the lines are parallel same side interior angles are supplementary

45+ (2x-5) = 180

Combine like terms

2x +40 = 180

Subtract 40 from each side

2x+40-40 =180-40

2x = 140

Divide by 2

2x/2 = 140/2

x = 70

x = 70

Which of the following is not an item in the income statement? SELECT ONLY ONE a. Discount allowed b. Furniture & Fixture c. Furniture & Fixture d. Discount received

Answers

The item that is not an item in the income statement is b. Furniture & Fixture as it is considered a fixed asset and is reported on the balance sheet instead.

The income statement, also known as the profit and loss statement, provides a summary of a company's revenues, expenses, gains, and losses over a specific period. It helps to assess the financial performance of a business. The income statement typically includes various items such as revenues, cost of goods sold, operating expenses, interest income or expense, and other gains or losses.

a. Discount allowed is a revenue item that represents the discounts given to customers as an incentive for early payment or other reasons. It is usually reported as a deduction from sales revenue.

c. Furniture & Fixture is not typically included in the income statement. Instead, it is considered a non-operating or non-recurring item and is generally classified as a fixed asset on the balance sheet. Fixed assets represent long-term investments made by a company for its operations.

d. Discount received is also not an item in the income statement. It represents the discounts received by a company from its suppliers for early payment or other reasons. Similar to discount allowed, it is usually reported as a deduction from the respective expense account.

In summary, b. Furniture & Fixture is the item that is not included in the income statement. It is considered a fixed asset and is reported on the balance sheet instead.

7. The sum of two numbers is 48. Find the numbers if the second is three more than four times the first

Answers

If the sum of two numbers is 48, we can call our numbers x and 48 - x.

Let's call our first number x and our second number 48 - x.

Now read through the rest of the problem.

The second, 48 - x, is, equals, 3 more than 4 times the first, 4x + 3.

So we have the equation 48 - x = 4x + 3.

Solving from here, we subtract 4x from both sides and we have 48 - 5x = 3.

Now subtract 48 from both sides and we have -45 = -5x.

Finally, divide both sides by -5 and remember that

a negative divided by a negative always equals a positive.

So we have 9 = x.

So our first number is x and our second is 48 - x or 48 - 9 which is 39.

Julio is paid 1.4 times his normal hourly rate for each hour he works over 30 hours in a week. Last week he worked 40 hours and earned $462.00. Write and solve an equation to find Julio's normal hourly rate, r. Explain how you know that your answer is reasonable . Help me

Answers

Answer:

$10.50

Step-by-step explanation:

Let his hourly rate be represented by h

From the question,

30h + 1.4 (40 - 30)h = $462.00

30h + 1.4(10)h = $462.00

30h + 14h = $462.00

44h = $462.00

h = $462.00/44

h = $10.50

Therefore, Julio's hourly rate is $10.50

What assumptions underlie the least square method for the multiple regression? Explain why two perfectly multicollinear regressors cannot be included in a linear multiple regression.

Answers

The least squares method for multiple regression relies on several assumptions: Linearity, Independence, Homoscedasticity, No perfect multicollinearity.

Linearity: The relationship between the predictors (regressors) and the response variable is assumed to be linear.

Independence: The observations are assumed to be independent of each other. This means that the value of one observation does not influence the value of another observation.

Homoscedasticity: Homoscedasticity assumes that the variance of the errors (residuals) is constant across all levels of the predictors. In other words, the spread of the residuals should be roughly the same for all predicted values.

No perfect multicollinearity: Perfect multicollinearity refers to a situation where there is an exact linear relationship among the predictor variables. When two or more predictors are perfectly multicollinear, it means that one predictor can be expressed as a perfect linear combination of the others. Including two perfectly multicollinear regressors in a multiple regression model leads to problems because it becomes impossible to estimate unique regression coefficients for those predictors.

Including two perfectly multicollinear regressors in a multiple regression model creates a situation known as singularity or degeneracy. In such cases, the inverse of the matrix required for solving the normal equations (used in the least squares estimation) does not exist. Consequently, it becomes impossible to obtain unique estimates for the regression coefficients. This issue arises because the system of equations becomes underdetermined due to the redundant information provided by the multicollinear variables.

You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]

So, the Change In X is: -1 - 4 = -5

And the Change in Y is: 6 - 1 = 5

Once you divide both of the changes by 2, you get

X: [tex]-\frac{5}{2}[/tex]

Y:  [tex]\frac{5}{2}[/tex]

So the midpoint is: ( [tex]-\frac{5}{2}[/tex], [tex]\frac{5}{2}[/tex])

So, the Change In X is: -3 - (-9) = 6

And the Change in Y is: 4 - 3 = 1

Once you divide both of the changes by 2, you get

X: 2

Y:  [tex]\frac{1}{2}[/tex]

 So the midpoint is: ( 2, [tex]\frac{1}{2}[/tex])

__________________________________________________________

No. 4

You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]

So, the Change in X is: -1 - X

And the Change in Y is: -12 - Y

Once you divide both of the changes by 2, you get

X:  [tex]\frac{-1-X}{2} = -9[/tex]

    -1 - X = -18

    -X = -17

     X = 17

Y:  [tex]\frac{-12-Y}{2} = -7[/tex]

     -12 - Y = -14

     -Y = -2

      Y = 2

So the endpoint is: (17, 2)

__________________________________________________________

No. 5

You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]

So, the Change in X is: -14 - X

And the Change in Y is: -13 - Y

Once you divide both of the changes by 2, you get

X:  [tex]\frac{-14-X}{2}=-11[/tex]

    -14 - X = -22

    -X = -8

     X = 8

Y:  [tex]\frac{-13-Y}{2} =-10[/tex]

     -13 - Y = -20

     -Y = -7

      Y = 7

So the endpoint is: (8, 7)

Answer:

Step-by-step explanation:

8 hundredth is ten larger that 8 thousands so Jim is correct and Lou is not right for the following reason:

8 hundredth means that the number is on the right side after the decimal

if we put it as a fraction:

8/100 and 8/1000

comparing:

take a common denominator(1000 for the two fractions)

8/100=80/1000

80/1000>8/1000

the nominator 80 is greater than 8

( this is one way to compare and prove)

Lou is wrong because on the number line 0.008 comes before 0.08

for example a number 2.08( 2 and 8 hundredth)

and 2.008 ( 2 and 8 thousandth)

ones   decimal       tenth         hundredth         thousandth

 2            .                0                  0                         8

QUESTION 8 We will define a checkerboard matrix to be a square matrix A = (aj), where if i + j is even dij = if i + j is odd 8.1 Write out the 4x4 checkerboard matrix. 8.2 Find the basis for the nullspace of A, and the nullity and rank of A. 8.3 What will be the rank and nullity of the 17x17 checkerboard matrix?

Answers

The 4x4 checkerboard matrix is constructed with alternating 1s and 0s based on the position of the elements. The basis for the nullspace of the checkerboard matrix is found, and its nullity and rank are determined. Additionally, the rank and nullity of a 17x17 checkerboard matrix are determined.

8.1 To construct the 4x4 checkerboard matrix, we assign values based on the parity of the row and column indices. If the sum of the row index (i) and column index (j) is even, the element (aij) is 1. Otherwise, if the sum is odd, the element is 0. The resulting 4x4 checkerboard matrix is:
A = |1 0 1 0|
|0 1 0 1|
|1 0 1 0|
|0 1 0 1|
8.2 to find the basis for the nullspace of A, we need to solve the equation Ax = 0, where x is a vector. By performing row operations on the matrix, we can bring it into row-echelon form:
|1 0 1 0|
|0 1 0 1|
|1 0 1 0|
|0 1 0 1|
Row 3 - Row 1:
|1 0 1 0|
|0 1 0 1|
|0 0 0 0|
|0 1 0 1|
Row 4 - Row 2:
|1 0 1 0|
|0 1 0 1|
|0 0 0 0|
|0 0 0 0|
The reduced row-echelon form shows that the last two rows are dependent on the first two rows. Therefore, the basis for the nullspace is the vector {(-1, 1, -1, 1)}. The nullity of A, which is the dimension of the nullspace, is 1.
The rank of A is the number of linearly independent rows, which in this case is 2.
8.3 The rank and nullity of the 17x17 checkerboard matrix can be determined using the same approach. Since the matrix is larger, it is not feasible to write it out here. However, we can observe a pattern based on the size of the matrix. For an n x n checkerboard matrix, if n is even, the rank will be n/2 and the nullity will also be n/2. If n is odd, the rank will be (n + 1)/2 and the nullity will be (n - 1)/2.
Therefore, for the 17x17 checkerboard matrix, the rank will be (17 + 1)/2 = 9, and the nullity will be (17 - 1)/2 = 8.
In summary, the basis for the nullspace of the 4x4 checkerboard matrix is {-1, 1, -1, 1}, resulting in a nullity of 1 and a rank of 2. For the 17x17 checkerboard matrix, the rank is 9, and the nullity is 8.
