What is the value of​ P(A)? What is the value of ​P(A​)?

Answer: The definition of a solution is a value or values which, when substituted for a variable in an equation, make the equation true. For example, the solutions to the equation x2 = 4 are 2 and -2. I hope this helped!

Answer:

the slope is -6

the y-intercept is 2

Step-by-step explanation:

y=mx+b where m is the slope and b is the y-intercept

a) Slope: -6;

b) y-intercept: 2, which means that the line touches the "y" axis on point (0, 2).

Given equation: [tex]y = -6x + 2[/tex].

Here's a little tip that will help you quickly find the slope and y-intercept.

First, solve the equation for "y". This equation is already solved for "y", this is called "slope-intercept form". Now, take a look at the attached image and identify the values. As you can tell, for the given equation, values are:

a) Slope: -6;

b) y-intercept: 2, which means that the line touches the "y" axis on point (0, 2).

You may verify this information using the algebraic methods (slope formula and substituting "x" by 0 and calculate "y"). It'll give you the same answer, this is just a faster way to find the values.

Answer:

B

Step-by-step explanation:

There are two types in this good ol' world, Salary and Hourly.

Hourly gets paid by, well, the hour

Salary has a set amount. Let's say there around is $1000 a week. If they work 70 hours, they get paid $1000, if they work 30 hours, they get paid $1000

Answer: The amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.

Step-by-step explanation:

Let's denote the amount invested at 6% as "x". Then, the amount invested at 9% would be "y", and the amount invested at 15% would be "z".

According to the problem, we have the following information:

x + y + z = $7500 (the total amount invested)

0.06x + 0.09y + 0.15z = $867 (the total annual income)

And,

z = x + y + $100 (the amount invested at 15% was $100 more than the amounts invested at 6% and 9% combined)

We can substitute the third equation into the first equation to get:

x + y + x + y + $100 = $7500

Simplifying:

2x + 2y + $100 = $7500

2x + 2y = $7400

Next, we can substitute "z = x + y + $100" into the second equation:

0.06x + 0.09y + 0.15(x + y + $100) = $867

Expanding:

0.06x + 0.09y + 0.15x + 0.15y + 0.15 * $100 = $867

0.21x + 0.24y + $15 = $867

0.21x + 0.24y = $852

Finally, we can solve for x and y using the equations "2x + 2y = $7400" and "0.21x + 0.24y = $852".

We can use elimination method to find x:

2x + 2y = $7400

0.21x + 0.24y = $852

Multiplying the first equation by 0.21:

0.42x + 0.42y = $1557.8

Subtracting the second equation from the first:

0.42x + 0.42y - 0.21x - 0.24y = $1557.8 - $852

0.21x - 0.03y = $705.8

Dividing both sides by 0.21:

x = $705.8 / 0.21 + 0.03y / 0.21

x = $3357.14 / 0.24 + y

Finally, substituting x back into the equation "2x + 2y = $7400":

2($3357.14 / 0.24 + y) + 2y = $7400

Expanding:

$6714.29 + 2.24y = $7400

Solving for y:

2.24y = $7400 - $6714.29

y = $685.71 / 2.24

y = $306.13

And finally, substituting y back into the equation "x = $3357.14 / 0.24 + y":

x = $3357.14 / 0.24 + $306.13

x = $1393.57

Therefore, the amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.

Answer:

TW = 9

Step-by-step explanation:

WY is the perpendicular bisector of TZ with TY ≅ ZY , then

Δ TWZ is isosceles with ZW ≅ TW , that is

3x = x + 6 ( subtract x from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

TW = x + 6 = 3 + 6 = 9

The difference in rainfall between the wettest and driest days is 3/8 inches.

The intensity of the rain is typically categorized as light, moderate, or heavy. Light precipitation is defined as less than 0.10 inches per hour. Rainfall that is considered moderate ranges from 0.10 to 0.30 inches per hour. More than 0.30 inches of rain per hour is considered heavy rainfall. under 0.5 mm per hour. Greater than 0.5 mm per hour but less than 4.0 mm per hour is considered moderate rain. Greater than 4 mm per hour but less than 8 mm per hour is considered heavy rain. greater than 8 mm per hour of extremely intense rain.

Rainfall in Rainiest day = 5/8

Rainfall in driest day = 2/8

So, The Difference = 5/8 - 2/8 = 3/8 inches

Hence, rainfall on the rainiest day 3/8 more than driest day

Proper fraction = 3/8

The total amount of Investment A is $6,348.58.

What is the compound interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

To find the total amount of investment A, you can use the formula for compound interest:

A = P * (1 + r/n)⁽ⁿᵗ⁾

Where P is the initial investment ($5,000), r is the annual interest rate (6%), n is the number of times interest is compounded per year (2 times), and t is the number of years invested (4).

A = 5000 * (1 + 0.06/2)⁽²*⁴⁾

= 5000 * (1 + 0.03)⁸

= 5000 * 1.03⁸

= 5000 * 1.269716

= $6,348.58

Hence, The total amount of Investment A is $6,348.58.

Step-by-step explanation:

1. The company’s degree of operating leverage is 4.

2. The degree of operating leverage is 3.34.

3. The new contribution is $17, 280.

How much a company's operating income alters in reaction to a change in sales is measured by the level of operating leverage.

1. Degree of operating leverage = Contribution /Net Operating Income

and, Contribution = 54,000

Net Operating Income = $13,500

Thus, operating Leverage = 54000/ 13500  = 4

2. If Company's sales increase by 7% then contribution also increases by 7%,

Revised Contribution = $54000 + 7% = $57780

and, Revised net Operating income = $57780- $40500

                                                            = 17280

Degree of operating leverage = 57780 / 17280  = 3.34

3. Contribution format income statement:

Sales = $90000+ 7% = $96,300

Less: Variable Cost 36, 000 + 7% = $38520

What is a three-variable linear equation?

When a, b, and c are constants, a linear equation in two variables has the form ax + by + c = 0. (real numbers). Similar to this, a three-variable linear equation has the form ax by c z plus d = 0, where a, b, c, and d are constants.

Let's call the three numbers x, y, and z, where x is the largest number and z is the smallest number. Then, we have the following information:

x + y + z = 54

x - z = 46

y + z = 13

From the second equation, we can find z:

z = x - 46

Substituting this into the third equation:

y + x - 46 = 13

y = 13 + 46 - x

Substituting both of these into the first equation:

x + (13 + 46 - x) + (x - 46) = 54

Expanding the parentheses:

2x = 154

Dividing both sides by 2:

x = 77

Substituting this value of x into the equation for z:

z = x - 46 = 77 - 46 = 31

And substituting it into the equation for y:

y = 13 + 46 - x = 13 + 46 - 77 = -18
