Step-by-step explanation:

The median wage of workers in the firm is given as follows:

Rs 2.37 per hour.

The median of a data-set is the middle value of a data-set, the value of which 50% of the measures are less than and 50% of the measures are greater than. Hence, the median also represents the 50th percentile of a data-set.

From the data-set in this problem, the median is obtained as follows:

Hence the median class is:

Rs 2.25 to Rs 2.49 per hour.

The median is the middle value of the class, hence:

(2.25 + 2.49)/2 = Rs 2.37 per hour.

Solving the provided question, we can say that Using quadratic formula, x = 19 or x = 3; Sum of the 2 numbers = 3 + 19 = 22

A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared. The formula "ax2 + bx + c = 0" is one of the often used solutions for quadratic equations. where are numerical coefficients or constants a, b, and c. where the variable "X" is unidentified.

Let x represent a number that is twice as far away from 5 than 17.

|x - 5| = 2|x - 17|

(x - 5)² = 4(x - 17)²

[tex]x^2 + 25 - 10x = 4(x^2 + 49 - 14x)\\x^2 + 25 - 10x = 4x^2 + 196 - 56x\\3x^2 - 46x + 171 = 0\\[/tex]

Answer:

28

Step-by-step explanation:

The constant variation, a, is equal to the product of x and y when they are both known. In this case, when x = 7 and y = 4, the constant variation is 4 * 7 = 28. So, the equation for the inverse variation is y = 28 / x.

Note that in question 28 above:

X = 56° (Alternative Angles)

Y = 124° (Angles in a straight line)

Z = 81° (Sum of angles in an irregular parallelogram).

in Question 29,
x = 126° (Co-interior angles and Bisector theorem).

Question 28: Note that the sum of angles in an irregular parallelogram always equal 360°. Since X and 56° are alternate angles and are therefore congruent, and Y and 56° are on the same line and therefore sum up to 180°, resulting in Y being equal to 124°, then we have three interior angles of an irregular parallelogram:

∠X = 56°

∠Y = 124°; and

∠99° (As given), which is co-interior with ∠Z

Thus whether by the Co-interior principle where two co-interior angels sum up to 180° or by sum of angles in an irregular parallelogram, we will still obtain a result where:

∠Z = 81°. That is

360° = 56 + 124 + 99 + ∠Z

∠Z = 360 - (56 + 124 + 99)
∠Z = 81°

OR

Using the Co-Interior angles theorem, we can state that:

∠Z = 180 - 99
∠Z = 81°

Question 29:
Recall that an angle bisector of a triangle's angle divides the opposing side into two portions that are proportionate to the triangle's other two sides, according to the angle bisector theorem.

Thus, we can state that 27° is half of the angle whose Co-interior is x.

Thus ∠x = 180 - (27*2)

∠x = 180 -54
∠x = 126°

Answer:

Thus, the equation of line for point (-1, 2)  is y = x + 3.

Step-by-step explanation:

Answer:

The equation of the line is y = x + 3.

Step-by-step explanation:

A line that is parallel to y=x+4 and passes through the point (-1,2) will have the same slope as y=x+4. The slope of y=x+4 is 1, so the equation of the line will be in the form y = mx + b, where m=1. To find b, we can plug in x = -1 and y = 2 into the equation and solve for b.

y = mx + b

y = 1 * -1 + b

y = -1 + b

b = y + 1

b = 2 + 1

b = 3

Answer:

A. 1436.03 ft³

Step-by-step explanation:

V = (4/3)πr³

V = (4/3)(3.14)(7 ft)³

V = 1436.03 ft³

The slope intercept form of the equation is given as y = 0.75x + 1.75

The slope-intercept form of a line is given by y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope (m) is the cost per taco, which is $0.75. The y-intercept (b) is the cost of the drink, which is $1.75.

So, the equation that represents the total cost (y) for x number of tacos and a drink is:

y = 0.75x + 1.75

This equation states that for every taco ordered (x), the cost will increase by $0.75, and the minimum cost will always be $1.75 for the drink.

Lisa's remaining of her monthly income is $490. Her net worth is $142.980. Her saving ratio is 17%, liquidity ratio is 23% and Debt-to-asset ratio is 63%.

Based on the given data, we can construct Lisa's personal cash flow statement and personal balance sheet as:

Personal Cash Flow Statement

Cash Inflow:

Cash Outflow:

Debts:

Living expenses:

Total cash = $490

Personal Balance Sheet

Assets:

Total Assets = $383,140

Liabiities:

Total Liabilties = $240,160

Net worth = $142,980

Saving ratio can be calculated by assuming that the amount of Lisa's cash on bank is her saving. Then:

saving ratio = saving : net income

Saving ratio = cash in bank : net income

Saving ratio = $600 : $3,600

Saving ratio = 17%

Liquidity ratio is calculated by comparing Lisa's current assets with her net worth. Hence:
Liquidity ratio = Current assets : Net worth

Liquidity ratio = (Cash in bank + Car + Clothing owned + Furniture) : Net worth

Liquidity ratio = ($600 + $18,000 + $540 + $14,000) : $142,980

Liquidity ratio = 23%

Debt-to-asset ratio = Total Liabilities  : Total Assets

He wants to DIVIDE the 3/4 gallon into 5 bux

 so divide 3/4 by 5

3/4  /  5 = (3/4) / (5/1) = 3/4 * 1/5 = (3*1) / ( 5*4) = 3/20 gallon per bux

The amount of paint that Ralph store in each container is 3/20 gallon.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Total amount of paint that Ralph has = 3/4 gallon

He wants to store all of the paint equally among 5 containers.

If the paint is stored in 5 containers,

Amount of paint in each container = 3/4 ÷ 5

                                                         = 3/4 × 1/5

y=4 is the minimum y-value after which the exponential function will always be greater than the linear function.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

From the graph we can see that in the interval [0,1] the value of y is less than 1.

In the interval [1,2] the value of y value is 2 to 4.

In the interval [2,infinity) the graph is going up, and the value of y is greater than or equal to 4.

Therefore, the graph going up after y=4 above the line.

This expression gives the average rate of change of the function over the interval [4, b].

The average rate of change of a function on an interval is equal to the rise (change in the y-value) divided by the run (change in the x-value) over that interval.

For f(x) = 7x² - 6 on the interval [4, b], the average rate of change can be found by calculating the slope of the secant line connecting the points (4, f(4)) and (b, f(b)).

Therefore, the average rate of change of f(x) = 7x² - 6 on the interval [4, b] is:
