A card is randomly drawn from a standard deck of 52 cards. What is the probability that the card is a king of diamonds, given that the card drawn is a king?
Answer:
There are four kings in a standard deck of 52 cards, so the probability of drawing a king is 4/52 or 1/13.
Since we know that the card drawn is a king, there are now only four possible cards that could have been drawn: the king of spades, the king of hearts, the king of clubs, and the king of diamonds.
Out of these four possibilities, only one of them is the king of diamonds. Therefore, the probability that the card is a king of diamonds, given that the card drawn is a king, is 1/4.
In other words, the conditional probability of drawing the king of diamonds given that a king has been drawn is:
P(king of diamonds | king) = P(king of diamonds and king) / P(king) = 1/52 / 4/52 = 1/4

Find the area of a circle with circumference is 60 CM
Answer:
900/π square centimeters or 286.62 square centimeters
Step-by-step explanation:
The circumference of a circle is given by the formula:
C = 2πr
where C is the circumference and r is the radius of the circle.
We are given that the circumference is 60 cm, so we can set up the equation:
60 = 2πr
Solving for r, we get:
r = 60/(2π) = 30/π
The area of a circle is given by the formula:
A = πr^2
Substituting the value of r, we get:
A = π(30/π)^2 = 900/π square centimeters
Therefore, the area of the circle is approximately 286.62 square centimeters, rounded to two decimal places.
Zaara and mehrine brought the same amount of money to the shopping mall. Mehrine spent rs 500 on shoes and zaara bought a dress for rs 2000. After their shopping zaara had 2/3 of what mehrine had left. How much money did mehrine bring for shopping
Since Mehrine and Zaara both brought equal amount of money for shopping, Mehrine brought Rs. 5000 for shopping.
What are Linear equations?
Linear equations are equations whose highest power of the variables is 1. The graph of a linear equation is a straight line.
Let the equal amount of money they both brought = x
Mehrine spent Rs 500 on a pair of shoes, therefore, the money Mehrine has left
= x-500
Zaara bought a dress for Rs 2000, therefore, the money Zaara has left
= x-2000
Zaara has ⅔ of what Mehrine had left.
Therefore:
[tex]x - 2000 = \frac{2}{3}(x - 500)[/tex]
Cross multiply
3(x - 2000) = 2(x - 500)
3x - 6000 = 2x - 1000
3x - 2x = 6000 - 1000
x=5000
Therefore, Mehrine brought Rs5000 for shopping.

A consumer is trying to decide between two long-distance callingplans. The first one charges a flat rate of $0. 10 per minute,whereas the second charges a flat rate of $0. 99 for calls up to 20minutes in duration and then $0. 10 for each additional minuteexceeding 20 (assume that calls lasting a noninteger number ofminutes are charged proportionately to a whole-minute'scharge). Suppose the consumer's distribution of call durationis exponential with parameter λ. Which plan is better if expected call duration is 10 minutes? 15minutes? [Hint: Let h1(x) denote the cost for the firstplan when call duration is x minutes and let h2(x) bethe cost function for the second plan. Give expressions forthese two cost functions, and then determine the expected cost foreach plan. ]
The calling plan was a logical decision that was made. For calls with a shorter estimated time (10 minutes), the first plan is selected; for calls with an extended expected duration, the second plan is favoured (15 minutes).
Let the costs for the first and second plans, respectively, be denoted by h₁(x) and h₂(x), while the call lasts for x minutes.
The expressions for these two cost functions are as follows, according to the information available:
h₁(x) = 10x
h₂(x) = 99; if x ≤ 20 and 99 + 10(x - 20); if x > 20
Let X represent how long the call was. The exponential distribution of X has a parameter value of λ = 1/10 if the anticipated call time is 10 minutes.
That is, X ~ exp(λ = 1/10)
The exponential distribution's density function with parameter λ = 1/10 is,

The side lengths and the angle measures is PQ = 2, PR ≈ 3.61, QR = 3
m∠P = 90°, m∠Q = 90°, m∠R ≈ 33.7°
Tο find the side lengths, we need tο use the distance fοrmula:
PQ = √[(x₂ - x₁)² + (y₂ - y₁)²]
PR = √[(x₃ - x₁)² + (y₃ - y₁)²]
QR = √[(x₃ - x₂)² + (y₃ - y₂)²]
PQ = √[(-4 - (-2))² + (4 - 4)²] = √[2²] = 2
PR = √[(-4 - (-2))² + (1 - 4)²] = √[2² + 3²] = √13 ≈ 3.61
QR = √[(-4 - (-4))² + (1 - 4)²] = √[3²] = 3

cοs(m∠P) = (13 + 9 - 4) / (2 * √13 * 3)
cοs(m∠P) = 18 / (2√39)
m∠P = cοs⁻¹(18 / (2√39)) ≈ 90°
cοs(m∠Q) = (PQ² + QR² - PR²) / 2PQQR

The first statement is correct, that the value of x is 55°.
The second statement is incorrect, the correct statement is the measure of the smaller angle is 35°.
What is the complementary angle?Complementary angles are those whose combined angle is exactly 90°
Part A :
The figure shows right-angled or complementary angle which means the sum of angles is 90°
Therefore we can say that,
x + x-20 = 90°
2x - 20 =90°
2x = 90° + 20
2x = 110°
x = 55°
Therefore the value of the x = 55°, the first statement correct.
The measure of the smaller angle is
= x - 20°
= 55° - 20°
= 35°
The second statement is incorrect.
The correct statement is a measure of the smaller angle is 35°.
Part B:
The figure shows the supplementary angle and the sum of the supplementary angle is 180°.
3x + 6x = 180°
9x = 180°
x = 20°
The first statement is incorrect, the correct statement is the value of x = 20.
The angle measure is 3x = 3 * 20 = 60° and 6x = 6 * 20 = 120°
This means that the second statement is correct.
Part C:
Given that the angle is complementary. the first angle is 2x and the second angle is (3x-5).
A complementary angle is the sum of the angles equal to 90°
2x + 3x-5 = 90
5x = 90 - 5
5x = 85
x = 17°
The first statement is incorrect. the correct statement is the value of x = 17.
The measure of the angle,
2x = 2 * 17 = 34
3x - 5 = 3 * 17 - 5 = 51 - 5 = 46
From the above result, second statement is also incorrect, the correct statement is the measure of the larger angle is 46°.

Write your answer as a fraction or whole number.
The probability of Roger selling a zucchini bread as the next loaf is 4/21.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The probability of Roger selling a zucchini bread as the next loaf can be found by dividing the number of zucchini breads sold by the total number of breads sold so far.
The total number of breads sold so far is:
11 (banana) + 8 (zucchini) + 9 (cranberry) + 14 (blueberry) = 42
The number of zucchini breads sold is 8.
So the probability that the next loaf Roger sells will be zucchini bread is:
8/42 = 4/21
Therefore, the probability of Roger selling a zucchini bread as the next loaf is 4/21.

If $5,000 is borrowed with an interest of 12. 3% compounded semi-annually, what is the total amount of money needed to pay it back in 3 years?
Round your answer to the nearest cent.
Do NOT round until you have calculated the final answer
As per the concept of compound interest, the total amount of money needed to pay back the loan in 3 years is $6,035.50.
Now, let's move on to the problem. You are given that $5,000 is borrowed with an interest of 12.3% compounded semi-annually. This means that the interest rate of 12.3% is divided by 2 to get the semi-annual interest rate, which is 6.15% (12.3% / 2). The interest is compounded twice a year, so there will be 6 months between each compounding period.
To find the total amount of money needed to pay back the loan in 3 years, we need to use the formula for compound interest:
A = P(1 + r/n)ⁿˣ
where:
A = the total amount of money needed to pay back the loan
P = the principal amount borrowed
r = the annual interest rate (in decimal form)
n = the number of times the interest is compounded per year
x = the number of years
In this case, we have:
P = $5,000
r = 12.3% = 0.123
n = 2 (compounded semi-annually)
x = 3 years
So the formula becomes:
A = $5,000(1 + 0.0615/2)²ˣ³
Simplifying this, we get:
A = $5,000(1.03075)⁶
Using a calculator, we can find that 1.03075 raised to the power of 6 is approximately 1.2071. So:
A = $5,000(1.2071)
A = $6,035.50

The two solutions of the equation x2 - 4x + 1 = 0 are x = 2 + √3 and x = 2 - √3.
A quadratic equation is an equation that can be written in the form ax2 + bx + c = 0, where a, b, and c are real numbers and a is not equal to 0. Solving a quadratic equation involves finding the value of x that makes the equation true. This can be done in multiple ways, but the most common method is to use the Quadratic Formula. The Quadratic Formula states that the roots (or solutions) of a quadratic equation can be found using the following formula:
x = [-b ± √(b2 - 4ac)]/2a
For example, consider the equation x2 - 4x + 1 = 0. In this equation, a = 1, b = -4, and c = 1. Plugging these values into the Quadratic Formula gives us:
x = [-(-4) ± √((-4)2 - 4(1)(1))]/2(1)
Simplifying this equation, we get:
x = [4 ± √(16 - 4)]/2
Finally, simplifying further yields the following two solutions:
x = (4 ± √12) /2
x = 2 ±√3

2x + 3y = 4 and -6y-2x=2 solve. Simultaneously
The values of x and y that satisfy the system of equations are x = 5 and y = -2.
To solve these equations simultaneously, we can use the method of substitution.
First, let's solve one of the equations for one of the variables. We can rearrange the first equation to solve for x:
2x + 3y = 4
2x = 4 - 3y
x = (4 - 3y)/2
Now we can substitute this expression for x into the second equation and solve for y:
-6y - 2x = 2
-6y - 2((4-3y)/2) = 2
-6y - 4 + 3y = 2
-3y = 6
y = -2
We have found that y = -2. We can now substitute this value back into either of the original equations to solve for x. Let's use the first equation:
2x + 3y = 4
2x + 3(-2) = 4
2x = 10
x = 5
Therefore, the solution to the system of equations is x = 5 and y = -2.

What is inequality?In mathematics, inequality is a statement that expresses the relationship between two values, where one value is greater than, less than, or equal to the other. Inequalities can be expressed using symbols such as > (greater than), < (less than), and = (equal to). Inequality can be used to compare two values or expressions, or to determine if a given number is within a certain range. Inequalities can be used to solve problems, such as finding the area of a triangle, or to model real-world situations, such as determining the maximum number of people that can fit in a room.

A rectangular prism has a base with an area of 200cm2. The. Volume of the prism is 3,000cm3 what is the height of the prism
Answer:
height = 15 cm
Step-by-step explanation:
Base area of a prism B = hw where h = height, w = width
So B = lw = 200 cm²
Volume V = lwh = 3000 cm³
V/B = lwh/lw = h
h = 3000cm³/200cm = 15 cm
Suppose that you want to model the height of a rider on a Ferris wheel as a function of time. The amplitude of the function you use as a model should be equal to which of the following?
the area of the Ferris wheel
the circumference of the Ferris wheel
the diameter of the Ferris wheel
the radius of the Ferris wheel
The amplitude οf the functiοn used tο mοdel the height οf a rider οn a Ferris wheel shοuld be equal tο the radius οf the Ferris wheel.
What is a Ferris wheel's typical height?212 feet is the average height. A 550-fοοt ferris wheel is the tallest οne. This may be fοund in Las Vegas, Nevada, and is knοwn as the high rοller.
The amplitude οf a periοdic functiοn, such as the height οf a rider οn a Ferris wheel as a functiοn οf time, is the maximum distance frοm the average οr equilibrium pοsitiοn. In this case, the average οr equilibrium pοsitiοn wοuld be the height οf the rider when the Ferris wheel is at its lοwest pοint. The distance frοm the lοwest pοint tο the highest pοint οf the Ferris wheel is equal tο the diameter, and half οf the diameter is equal tο the radius.

Solve the following exponential equation by expressing each side as a power of the same base and then equating exponents. 53−x=251 The solution set is White an equation for line L in point-slope form and slope-intercept form.

Use integprs or fractions for any nurbers ti the equation)
The equation for line L in slope-intercept form is y = -1/4x + x₁/4 + y₁
The exponential equation is 53−x=251. Therefore, we need to express each side as a power of the same base and then equate exponents. Let's express both sides with the same base 5. We know that 251 is the same as 5². Thus, the equation can be rewritten as:
53−x=251=5².
We need to express 53−x as a power of 5. To do that, we can write it as:
53−x = 5³/x.
Now, we can substitute this expression into our equation to get:
5³/x=5²
Let's multiply both sides of the equation by x to eliminate the fraction:
5³=5²x.
Divide both sides by 5² to get:x = 5. We can check our solution by plugging it back into the original equation:
53−5=25, which is true.
Thus, the solution set is {5}.The equation for line L in the point-slope form: We know that L is perpendicular to y=4x. Thus, the slope of L is -1/4. We also know that L passes through a point (x₁, y₁). Let's write the point-slope form of the equation:
y - y₁ = -1/4(x - x₁).
The equation for line L in slope-intercept form: Let's solve this equation for y to get it in slope-intercept form:
y - y₁ = -1/4(x - x₁).
Multiply both sides by 4 to eliminate the fraction:
4y - 4y₁ = -x + x₁.
Simplify by moving -x + x₁ to the right side:
4y = x₁ - x + 4y₁.
Add x to both sides:
4y + x = x₁ + 4y₁
