There will be 12 combination of  different king-queen.

When grouping objects or figuring out how many subgroups can be created from a given collection of objects, combinations are employed. We also employ permutations to calculate the number of possible combinations of unrelated things.

To determine the number of different king-queen combinations, we need to multiply the number of candidates for king by the number of candidates for queen. In this case, there are four candidates for homecoming queen and three candidates for king.

There are 4 candidates for queen and 3 candidates for king, so:

4 x 3 = 12

Therefore, the total number of different king-queen combinations is 4 multiplied by 3, which equals 12. So, there are 12 different king-queen combinations.

The area expression as products is 7 * (8 + 6)

From the question, we have the following parameters that can be used in our computation:

Area = 54 + 42

Express 54 as a product of 7 and 8

So, we have the following representation

Area = 7 * 8 + 42

Express 42 as a product of 7 and 6

So, we have the following representation

Area = 7 * 8 + 7 * 6

Factor out 7

This gives

Area = 7 * (8 + 6)

Hence, the expression using GCF is 7  * (8 + 6)

The square root of a number can also be negative number so x could also be -9

Square root of a number is the number such that if it is multiplied by itself we get the square. The opposite of squaring an integer is finding its square root. As we know multiplication of two negative numbers produce a positive number. this is the reason why square of both positive and negative numbers are both positive. therefore, square root of a number can also be positive or neegative both.

Answer:

A(10) = $13,961.50

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 5.25/100

r = 0.0525 rate per year,

Then solve the equation for A

The formula is given as:

A = Pe^rt

P = 8259

r = 0.0525

t = 10 years.

Hence,

A = 8,259.00 × e^(0.0525×10)

A = $13,961.50

Therefore, the money that will be in the account after 10 years is $13,961.50

Answer:

\(-3\frac{1}{2}<-3\frac{1}{3}\)

Step-by-step explanation:

-3.5 means -(3 + \(\frac{1}{2}\))

In other words, -3.5 = \(-3\frac{1}{2}\)

When we draw two numbers \(-3\frac{1}{3}\) and \(-3\frac{1}{2}\) on a number line, \(-3\frac{1}{2}\) comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, \(-3\frac{1}{2}\) is smaller than \(-3\frac{1}{3}\).

\(-3\frac{1}{2}<-3\frac{1}{3}\)

Disregarding intermediate, let's assume she has access to a letter that can be powerful or weak. Let's say she receives a persuasive letter. If she receives a strong letter, her chance of being hired is then increased.

P(J|S)

If, however, she receives a subpar letter, Considering since she received a subpar cover letter, her chances of landing the job are slim.

P(J|W)

Let's assume that we have some knowledge of such two numbers. I believe

In addition, we recognize how likely it is that she will receive either one or both letters: P(J|S)=0.8 P(J|W)=0.1

Note that P(S)+P(W)=1 since there are only two possibilities: P(S)=0.7 and P(W)=0.3.

P(J)=P(J|S) P(S)+P(J|W) P(W)

This is a representation of two distinct directions that could be taken. In one, we receive a compelling letter and ponder if she'll be hired in light of that compelling letter. As a result of the weak letter from the other, we are unsure if she will be hired. We give the pathway carrying the formal letter a higher weight because there is a substantially larger chance of receiving it compared to a weak letter.

Suppose we have a bag containing 3 red marbles and 2 blue marbles. We draw a marble out of the bag without looking, record the color, and then put the marble back in the bag. We repeat this process 4 times, drawing one marble at a time.

Let's define the following events:

The probability of event A occurring is 3/5, or 60%. This is because there are 3 red marbles out of a total of 5 marbles.

The probability of event B occurring is 2/5, or 40%. This is because there are 2 blue marbles out of a total of 5 marbles.

Now, suppose we want to know the probability of event B occurring, given that event A has already occurred.

The gradient of the line A and B are 4 and 2 respectively.

The gradient of a graph is the slope of the graph. The gradient is the change in the dependent variable with respect to the change in the independent variable.  

Gradient is rise over run,

Therefore, let's find the gradient of line A and B.

Hence,

gradient  = change in y/ change in x

gradient = y₂ - y₁ / x₂ - x₁

Hence, the gradient of A is as follows:

using (2, -1) and (3, 3)

gradient of A = 3 + 1 / 3 - 2

gradient of A = 4 / 1

gradient of A = 4

Let's find gradient of B

The price of the tablet computer after discount and marked up is $663.3.

What is discount?

Discount is the state of having a bond's price lower than its face value. The difference between the purchase price and the item's par value is the discount.

Discounts are different types of price reductions or deductions from a product's cost. It is frequently employed in consumer transactions when consumers receive discounts on a range of goods. The % discount rate is provided.

Here the original price of tablet computer = $670

During a sale , store offered 10% discount then

=> Price of tablet computer = 670× ( 100%-10%) = 670 × 90%

Now after the sale the price of the tablet computer marked up 10%. Then,

=> Price of tablet computer = 670 × 90% × (100%+10%)

=> Price of tablet computer = 670 × 90% × 110%

=> Price of tablet computer = 670 × \(\frac{90}{100} \times \frac{110}{100}\)

=> Price of tablet computer = 670 × 0.9 × 1.1 = $663.3

Tomas and Ana weigh 145 kilograms combined. Together, Ana and Rodrigo weigh the same as Tomas. Rodrigo is 39 kilograms in weight. Tomas is 92 kilograms in weight.

A mathematical statement with two equated algebraic expressions is known as an algebraic equation. Due to the presence of polynomials on both sides of the equal sign, an algebraic equation is also referred to as a polynomial equation.

A linear algebraic equation has a polynomial of degree 1 in it. A linear equation's most common form is a1x1+a2x2+...+anxn = 0, where at least one coefficient is a number that is not zero. Linear programming problems can be represented and solved with these linear equations.

Let X and Y represent Anna's weight and Tomas's.

Now,

\(X+Y=145 ............equation 1\\Y+39=X ..............equation2\)

We obtain this by transferring the value of X from equation 2 to equation 1,

\(Y+39+Y=145\\2Y+39=145\\2Y=145-39\\2Y=106\\Y=\frac{106}{2}\\ Y=53\)

Now that we have entered the value of Y into equation 2, we get:

Answer:

a. (5x - 2)° + (2x - 2)° + x° = 180°

b. m<113°,

m<K = 44°,

m<L = 23°

Step-by-step explanation:

Given:

m<J = (5x - 2)°

m<K = (2x - 2)°

m<L = x°

Required:

a. the equation to find x,

b. m<J, m<K, and m<L

Solution:

a. m<J + m<K + m<L = 180° (sum of triangle)

Substitute

(5x - 2)° + (2x - 2)° + x° = 180°

Solve for x

5x - 2 + 2x - 2 + x = 180

Add like terms

8x - 4 = 180

8x - 4 + 4 = 180 + 4

8x = 184

8x/8 = 184/8

x = 23°

b. ✔️m<J = (5x - 2)°

Plug in the value of x

m<J = 5(23) - 2 = 113°

✔️m<K = (2x - 2)° = 2(23) - 2

m<K = 44°

✔️m<L = x = 23°
