Answer:

The total amount of screws in the box is: 90+10 = 100.

The number of ways to select 10 screws from 100 is: N = (C100)^10.

The number of ways to select 10 screws from good ones is: m = (C90)^10.

Thus, the probability of taking 10 good screws is: P = m/N = ((C90)^10)/((C100)^10) = (90!*90!)/(80!*100!) ≈ 0.33

Connor can use multiplication to find the area of the picture by multiplying each sides and this will be equal to 25 unit².

It should be noted that the area of the rectangle will be the multiplication of the sides. Based on the information, ech unit square is 1 square inch. So far, he has made 3 rows with 5 unit squares in each row and he also sees that there will be 2 more rows of 5.

Therefore, Connor can use multiplication to find the area of the picture by illustrating thus:

= (3 × 5) + (2 × 5)

= 15 + 10

= 25 unit²

In conclusion, Connor can use multiplication to find the area of the picture by multiplying each sides and this will be equal to 25 unit².

The equation of the line through \((1,2)\) which make equal intercepts on the axis \(x+y=3\)

The equation of the line through (1,2) makes an equal intercept on the axis

The formula of the intercept form is

\(\frac{x}{a} +\frac{y}{b} =1\)

If they make an equal intercept

\(a=b\\\frac{x}{a} +\frac{y}{a} =1\\x+y=a\)

Put the value of the point in the axis, and we get.

\(1+2=a\\a=3\)

Put the value in the equation, and we get.

Six Sigma provides a continuous improvement framework and it has two methodologies.

DMAIC - Define, Measure, Analyze, Improve and Control.

DMADV - Define, Measure, Analyze, Design and verify

What is Six Sigma ?

According to the Six Sigma philosophies, every work can be broken down into discrete processes that may be measured, evaluated, improved, and managed.

                     Processes result in outputs after requiring inputs (x) (y). You can manage the outputs if you manage the inputs. This is typically written as y = f. (x).

What is a fundamental principle of Six Sigma?

The management practice known as "six sigma" aims to reduce errors. It is based on the idea that reducing defects is essential for improving margins, that costs can be cut, and that increasing customer loyalty can help because it is expensive to harbor defects.

A stock with a price-to-earnings (P/E) ratio of 24 can be justified considering the underwriting spread of 15 percent.

The P/E ratio is a commonly used valuation metric that compares the price of a stock to its earnings per share (EPS). A higher P/E ratio indicates that investors are willing to pay a premium for each dollar of earnings. In this case, a P/E ratio of 24 suggests that investors are valuing the stock at 24 times its earnings.

The underwriting spread, which is typically a percentage of the offering price, represents the compensation received by underwriters for their services in distributing and selling the stock. Assuming an underwriting spread of 15 percent, it implies that the offering price is 15 percent higher than the price at which the underwriters acquire the stock.

When considering the underwriting spread, it can have an impact on the valuation of the stock. The spread effectively increases the offering price and, therefore, the P/E ratio. In this scenario, if the underwriting spread is 15 percent, it means that the actual purchase price for investors would be 15 percent lower than the offering price. Thus, the P/E ratio of 24 can be justified by factoring in the underwriting spread, as it adjusts the purchase price and aligns the valuation with market conditions and investor sentiment.

They are asking what number is in the second row, first column.

(a) Solution Using Gauss Elimination with Partial Pivoting is  (-5/7, -6/7, 13/14).
(b) Solution Using Gaussian Elimination with Full Pivoting is (2/3, 1, -1).

(a) Gauss elimination with partial pivoting:

Starting system:

4x1 + x2 − 3 = −2

5x1 + x2 + 2x3 = 4

6x1 + x2 + x3 = 6

Row 1: Divide by 4 to get a leading 1

x1 + (1/4)x2 - (3/4) = -(1/2)

Row 2: Subtract 5 times row 1 from row 2

(1/4)x2 + 2x3 = (14/4)

Row 3: Subtract 6 times row 1 from row 3

(1/4)x2 + (7/4)x3 = (15/2)

Row 2: Multiply by 4 to get leading 1

x2 + 8x3 = 14

Row 3: Subtract (1/4)x2 from row 3

(7/4)x3 = (13/2)

Row 3: Divide by 7/4

x3 = (13/14)

Substitute back into row 2 to solve for x2

x2 = 2 - 8x3 = 2 - 8(13/14) = -6/7

Substitute back into row 1 to solve for x1

x1 + (1/4)x2 - (3/4) = -(1/2)

x1 = -1/2 - (1/4)(-6/7) + (3/4) = -5/7

Therefore, the solution is (-5/7, -6/7, 13/14).

(b) Gaussian elimination with full pivoting:

Starting system:

4x1 + x2 − 3 = −2

5x1 + x2 + 2x3 = 4

6x1 + x2 + x3 = 6

Swap rows 1 and 3 to put largest absolute value element in row 1 and column 1

6x1 + x2 + x3 = 6

5x1 + x2 + 2x3 = 4

4x1 + x2 − 3 = −2

Row 1: Divide by 6 to get a leading 1

x1 + (1/6)x2 + (1/6)x3 = 1

Row 2: Subtract 5 times row 1 from row 2

(1/6)x2 + (7/6)x3 = -1

Row 3: Subtract 4 times row 1 from row 3

(1/6)x2 - (7/6)x3 = -5

Row 2: Multiply by 6 to get leading 1

x2 + 7x3 = -6

Row 3: Add row 2 to row 3

x3 = -1

Substitute back into row 2 to solve for x2

x2 = -6 - 7(-1) = 1

Substitute back into row 1 to solve for x1

x1 + (1/6)x2 + (1/6)x3 = 1

x1 = 1 - (1/6) - (1/6) = 2/3

Therefore, the solution is (2/3, 1, -1).
