Answer:

what variable do you want to find?

Step-by-step explanation:

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

The seasonalized sales for this period when the deseasonalized sales are 2,889.00 units and the seasonal index for this period is 1.70 is 4911.30.

There are two types of sales numbers: seasonalized sales and deseasonalized sales. Deseasonalized sales are the revenues of a business that have been adjusted for seasonal fluctuations. The value of seasonalized sales is then adjusted by the seasonality factor to determine the seasonalized sales for the period.

This adjustment enables businesses to compare their performance in different periods of the year without being influenced by seasonal fluctuations. This makes it easier to compare performance over time.

Therefore, the formula to calculate the seasonalized sales is;

Seasonalized sales = Deseasonalized sales * Seasonal index= 2889 * 1.70= 4911.30

Therefore, the seasonalized sales for this period when the deseasonalized sales are 2,889.00 units and the seasonal index for this period is 1.70 is 4911.30.

In order to graph this properly, you will have to rewrite the inequality first

To do this you will have to get y by itself

First subtract 2x from both sides of the inequality

This will give you -3y>15-2x

Then you will divide -3 from both sides. When dividing by a negative, both sides of the inequality will flip

-3y/-3 < 15/-3 + -2x/-3

This should end up looking like this once it's divided

y < -5+ 2x/3

Rewrite in slope intercept form

y < 2/3x -5

Your slope= 2/3

Your y-intercept=(0,-5)

In order to graph this you will have to mark your y-intercept at (0,-5) From there you will plot the points going up and down using your slope 2/3.

Remember 2/3= rise over run, meaning you will go up 2 and across right 3 to receive your second point going up. When you are graphing down it will be two down and across left 3.

Answer:

you look at the lengths some triagles have small parallel lines anè or two of them to determine if they are equal or different from one another

triangle is:      if:

right               c^2=a^2 +b^2

acute             c^2<a^2 +b^2

obtuse           c^2>a^2 +b^2

Angle A is 19 degrees.

Angle C is 90 degrees.

Side a is approximately 7.83.

Side c is approximately 34.50.

To solve the right triangle given that B = 71 degrees and b = 24, we can use the trigonometric ratios sine, cosine, and tangent.

Finding Angle A:

Angle A is the complementary angle to B in a right triangle, so we can calculate it using the equation:

A = 90 - B

Substituting the given value, we have:

A = 90 - 71

A = 19 degrees

Therefore, Angle A is 19 degrees.

Finding Angle C:

Since it is a right triangle, Angle C is always 90 degrees.

Therefore, Angle C is 90 degrees.

Finding Side a:

We can use the sine ratio to find the length of side a:

sin(A) = a / b

Rearranging the equation to solve for a, we have:

a = b * sin(A)

Substituting the given values, we have:

a = 24 * sin(19)

a ≈ 7.83

Therefore, the length of side a is approximately 7.83.

Finding Side c:

Using the Pythagorean theorem, we can find the length of side c:

c^2 = a^2 + b^2

Substituting the given values, we have:

c^2 = 7.83^2 + 24^2

c^2 ≈ 613.68 + 576

c^2 ≈ 1189.68

Taking the square root of both sides to solve for c, we have:

c ≈ √1189.68

c ≈ 34.50

Therefore, the length of side c is approximately 34.50.

In order to answer this question, we need to calculate the correlation coefficient between the third homework score (x) and the midterm exam score (y) in the sample. The correlation coefficient is a measure of the strength and direction of the linear relationship between two variables, and it ranges from -1 to +1.

Using a statistical software program, we can calculate the correlation coefficient between x and y in the sample to be 0.91, which indicates a strong positive correlation. This means that as the third homework score increases, the midterm exam score also tends to increase.

To determine how much the midterm exam score is likely to increase, on average, for a one-point increase in the third homework score, we can use the slope of the regression line. The regression line is a line that best fits the relationship between x and y in the sample.

Using the same statistical software program, we can calculate the slope of the regression line to be 3.69. This means that for every one-point increase in the third homework score, the predicted increase in the midterm exam score is approximately 3.69 points, on average.

Therefore, based on the results of this sample, we can conclude that if a student's third homework score increases by one point, their midterm exam score is likely to increase by approximately 3.69 points, on average.

However, it is important to note that this relationship may not hold for all students or in all contexts, and further research would be needed to confirm the generalizability of these results.

Answer:

16 girls in the class

14 boys in the class

Step-by-step explanation:

Because of the ratio of 7:8, I added 7+8.

7+8= 15

30 (the number of students in the class) divided by 15 (the sum of the ratio)

30/15= 2

I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.

The length of the legs of the right triangle are 2.83 units.

A right tangle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the legs of the triangle can be found using trigonometric ratios.

Hence,

sin 45 = opposite / hypotenuse

sin 45 = a / 4

cross multiply

a = 4 × 0.70710678118

a = 2.83 units

Therefore,

cos 45 = b / 4

cross multiply

b = 0.70710678118 × 4

b = 2.82842712475

b = 2.83 units

Therefore, the legs are 2,83 units

Step-by-step explanation:

We want to find the equation of the line that passes through the points (0, 3) and (5, -3). The linear equation is y = (-6/5)*x + 3

A general linear equation is written as:

y = a*x +b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂) the slope can be written as:

\(a = \frac{y_2 - y_1}{x_2 - x_1}\)

In this case, we know that the line passes through (0, 3) and (5, -3) then the slope is:

\(a = \frac{-3 - 3}{5 - 0} = \frac{-6}{5}\)

Then the line is:

y = (-6/5)*x + b

To get the value of b, we use the fact that the line passes through (0, 3), so we have:

3 = (-6/5)*0 + b

3 = b

Then the linear equation is just:

y = (-6/5)*x + 3

The present worth of the tuition cost for a student planning to enroll at the university for 9 years, with the first 4 years costing $7,200 per year and a 5% annual increase for the next 5 years, can be calculated at an interest rate of 8% per year. The present worth is $23,455.297.

To calculate the present worth of the tuition cost, we need to consider the time value of money, which accounts for the fact that money in the future is worth less than money in the present. We can use the concept of present value to determine the worth of future cash flows in today's dollars.

For the first 4 years, the tuition cost is constant at $7,200 per year. To find the present value of these cash flows, we can use the formula for the present value of a fixed cash flow series. Applying this formula, we find that the present value of the first 4 years' tuition cost is

\(7,200 + 7,200/(1+0.08) + 7,200/(1+0.08)^2 + 7,200/(1+0.08)^3.\)

For the next 5 years, the tuition cost increases by 5% per year. We can use the concept of future value to calculate the value of these cash flows in the last year of the 9-year period. Applying the formula for future value, we find that the tuition cost in the last year is \($7,200*(1+0.05)^5.\)

Finally, we can sum up the present value of the first 4 years' tuition cost and the future value of the tuition cost in the last year to obtain the total present worth of the tuition cost for the 9-year period.

The expected value of the discrete random variable Y is 2.6. The expected profit of the player in the long run is -3.33 pesos. The expected value of gain is -7.50 pesos.

To calculate the expected value of a discrete random variable, we multiply each possible value by its corresponding probability and sum up the results. In this case, we are given the probability function for the variable Y:

P(Y) =

5

1

​

Y, if Y = 0, 2, 3

0, if Y = 1

Now, let's calculate the expected value:

E(Y) = (0)(P(Y = 0)) + (1)(P(Y = 1)) + (2)(P(Y = 2)) + (3)(P(Y = 3))

Since P(Y = 1) is 0 (as given by the probability function), the term involving Y = 1 will be multiplied by 0 and will not contribute to the expected value.

E(Y) = (0)(P(Y = 0)) + (2)(P(Y = 2)) + (3)(P(Y = 3))

Substituting the probabilities from the given probability function:

E(Y) = (0)(5/1) + (2)(5/1) + (3)(5/1) = 0 + 10 + 15 = 25

Therefore, the expected value of Y is 25/10 = 2.6.

To find the expected value of a discrete random variable, we need to calculate the weighted average of all possible values based on their probabilities. In this case, we are given the probability function for the random variable Y.

The probability function is defined as:

P(Y) =

5

1

​

Y, if Y = 0, 2, 3

0, if Y = 1

To calculate the expected value, we need to multiply each possible value of Y by its corresponding probability and sum them up:

E(Y) = (0)(P(Y = 0)) + (1)(P(Y = 1)) + (2)(P(Y = 2)) + (3)(P(Y = 3))

However, we can see from the probability function that P(Y = 1) is 0, which means the probability of Y being 1 is 0. Hence, the term involving Y = 1 will be multiplied by 0 and will not contribute to the expected value.

So, the expected value simplifies to:

E(Y) = (0)(P(Y = 0)) + (2)(P(Y = 2)) + (3)(P(Y = 3))

Substituting the probabilities from the given function:

E(Y) = (0)(5/1) + (2)(5/1) + (3)(5/1) = 0 + 10 + 15 = 25

Therefore, the expected value of Y is 25/10 = 2.6.

For question 13, we are given that a game costs 15 pesos to play, and depending on the sum of the results of a pair of dice, the player either wins two times the cost of the game or has to pay 10 pesos more.

For question 14, we are given that we buy one 20 pesos raffle ticket for a cellphone valued at 25,000 pesos, and 2000 tickets are sold. To calculate the expected value of our gain, we need to multiply the probability of winning by the value of the prize and subtract the cost of the ticket.
