A card is drawn from a standard deck of 52 cards and then placed back into the deck. Find the probability that a red card is drawn at least once by the third draw. Round your answer to two decimal places.

Answer:

Step-by-step explanation:

Two angles are said to be supplementary when their sum is equal to 180°.

Given angle 1 and 50° are supplementary.So, angle1+50°= 1880°

angle1 =180°-50°

angle 1=130°

Given 50° and angle 3 are supplementary

So,50°+ angle 3=18=0°

angle 3=130°

So angle 1 equals to angle

The mixture should contain 12 pounds of cashews and 18 pounds of Brazil nuts.

A physical combination of two or more unrelated substances is referred to as a mixture. For instance, water and salt are two different substances that, when combined, form a combination.

Let's call the amount of cashews used in pounds "x". The amount of Brazil nuts used in pounds can be calculated as 30 - x.

We know that the total cost of the mixture is $6.08 per pound * 30 pounds = $182.40.

The cost of the cashews in the mixture is $7.70 per pound * x pounds =$7.70x.

The cost of the Brazil nuts in the mixture is $5.00 per pound * (30 - x) pounds = $150 - $5.00x.

The total cost of the cashews and Brazil nuts in the mixture must equal $182.40, so we can set up the equation:

$7.70x + ($150 - $5.00x) = $182.40

Expanding and simplifying the equation:

$2.70x = $32.40

Dividing both sides by 2.70:

$x = 12

So, the mixture should contain 12 pounds of cashews and 18 pounds of Brazil nuts.

The expression  x²−−6 can be factored as:

[tex]x^{2} - 6 = (x + \sqrt{6} )(x - \sqrt{6})[/tex]

What is Factoring an expression?

A numerical or algebraic expression is factored when it is written as a product of factors. The distributive property can be used to factor expressions.

The expression  x²−−6 can be factored as:

[tex]x^{2} - 6 = (x + \sqrt{6} )(x - \sqrt{6})[/tex]

The solutions for this equation would be x = √6 or x = -√6. These are the values of x that make the expression equal to zero.

Factoring the expression in this way can be useful in solving related equations or in finding the roots of a quadratic function. It also helps in visualizing the graph of the function, as the factored form shows the x-intercepts, which are the points where the graph crosses the x-axis.

The table offers an average rate of change greater than the average rate of change of the function f(x) = x² + 2 · x - 1.

In this problem we need to determine two average rates of change, one from an equation and another from a table. Graphically speaking, average rate of change is the slope of a line secant to a curve and it can be computed by secant line formula:

m = [f(2) - f(- 2)] / [2 - (- 2)]

First, we proceed to determine the average rate of change for the function f(x) = x² + 2 · x - 1:

f(- 2) = (- 2)² + 2 · (- 2) - 1

f(- 2) = 4 - 4 - 1

f(- 2) = - 1

f(2) = 2² + 2 · 2 + 1

f(2) = 9

m = [9 - (- 1)] / [2 - (- 2)]

m = 10 / 4

m = 5 / 2

m = 2.5

And the average rate of change of the table:

m = (6.25 - 0.16) / [2 - (- 2)]

m = 0.09 / 4

m = 609 / 400

Here's a step-by-step explanation of the solution:

Calculate the government deposit: For every $1.00 you deposit, the government deposits $2.00. So if you deposit the maximum of $100.00 each month, the government deposit would be $100.00 * $2.00 = $200.00.

Calculate the total deposit each month: The total deposit each month is the sum of your deposit and the government deposit, so it would be $100.00 + $200.00 = $300.00.

Calculate the number of months: You started with $100.00 and made the maximum deposit of $100.00 each month for 5 years. Five years is 5 * 12 = 60 months.

Calculate the total deposit over 5 years: Over 5 years, you made 60 deposits of $300.00 each, so the total deposit over 5 years would be 60 * $300.00 = $18,000.00.

Calculate the final balance: Adding the initial deposit of $100.00 to the total deposit over 5 years, the final balance in your account after 5 years would be $18,000.00 + $100.00 = $18,100.00.

So, at the end of 5 years, if you deposited the maximum of $100.00 each month into the College Savings fund, you would have $18,100.00 in your account.

Answer:

Step-by-step explanation:

To solve this system of two equations with two variables (x and y), we'll use the substitution method. Here's how:

Solve one of the equations for either x or y, in terms of the other variable. Let's solve the first equation, 2x - 5y = 4, for x:

x = (4 + 5y)/2

Substitute the expression for x from step 1 into the second equation, 4x = 8 + 10y:

4(4 + 5y)/2 = 8 + 10y

Simplify the equation from step 2:

8 + 10y = 8 + 10y

Solve for y by subtracting 8 from both sides:

10y = 10y

Divide both sides by 10 to find the value of y:

y = y

Now that we have the value of y, we can substitute it back into the expression for x from step 1:

x = (4 + 5 *y)/2

So the solution to the system of equations is (x, y) = ((4 + 5 *y)/2, y=y).

The y-intercept of the line passing through the given points is -26 and the slope is -13/17

The y-intercept is the point where the graph intersects the y-axis.

Given that, the pair of coordinates of some points, we need to find the y-intercept,

To find the same, we will firstly find the equation of the line passing through these points,

We know that, the equation of a line passing through two points is given by,

y-y₁ = y₂-y₁ / x₂-x₁ (x-x₁)

Considering the points, (34, -52) and (51, -65)

The equation will be,

y+52 = -65+52 / 51-34 (x-34)

y+52 = -13/17(x-34)

y+52 = -13x/17+26

y = -13x/17-26

Hence, the y-intercept of the line passing through the given points is -26.

Answer: The simple interest on 16000 at 5% per annum for 1.5 years is calculated as:

I = P * r * t

I = 16000 * 0.05 * 1.5

I = 1200

The compound interest on 16000 at 5% per annum compounded half yearly for 1.5 years is calculated as:

A = P * (1 + r/n)^(nt)

A = 16000 * (1 + 0.05/2)^(2 * 1.5)

A = 16000 * (1.0253)^3

A = 16000 * 1.07897

A = 17253.576

The difference between the compound interest and simple interest is:

17253.576 - 1200 = 16053.576

So the difference between the simple interest and compound interest is 16053.576.

Answer:

  45°

Step-by-step explanation:

Given a polygon with an interior angle of 135°, you want to know the measure of the corresponding exterior angle.

At any given vertex of a polygon, the interior and exterior angles are supplementary:

  exterior angle = 180° - interior angle

  exterior angle = 180° -135°

  exterior angle = 45°

Answer: The sum of the interior angles of a regular polygon can be found using the formula:

(n-2)180°, where n is the number of sides of the polygon.

Let's call the number of sides of the polygon "s".

We know that one of the interior angles is 135°, so we can set up an equation using the formula for the sum of the interior angles:

s * 135° = (s-2)180°

Expanding the right side of the equation:

s * 135° = (s-2) * 180°

s * 135° = s * 180° - 360°

Solving for s:

135° = 180° - 360°/s

135° = 180° - 2 * 180°/s

135° = 180° - 2 * (180°/s)

180° - 135° = 2 * (180°/s)

45° = (180°/s)

So, s = 180° / 45° = 4 sides.

The size of one exterior angle can be found by subtracting each interior angle from 360°:

360° - 135° = 225°.

Therefore, one exterior angle of the polygon is 225°.

Using the unitary method we found that the amount that Bill should receive is $500 and the amount that his boss owes him is $26.

What is meant by the unitary method?

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. Once we have determined the value of a single unit, we may multiply that value by the number of units needed to determine the value of the other units. The concept of ratio and proportion is mostly applied using this way. Recognizing the units and values is crucial when using the unitary technique to a problem.

Given,

    Money received for each document = 25 cents

  Number of documents prepared by Bill = 2000

  The amount he received = $474

a) The correct total pay that Bill should receive = 2000*25 = 50,000cents

   Using the unitary method,

                   1 dollar = 100 cents

                  50,000 cents = 50000/100 = $500

b) The amount that his boss owes him = 500 - 474 = $26

Therefore using the unitary method we found that the amount that Bill should receive is $500 and the amount that his boss owes him is $26.
