Classifying polynomials refers to categorizing polynomials based on the degree of the polynomial and the number of terms in the polynomial.

The degree of a polynomial is the highest exponent in the polynomial. Polynomials can be classified into several types, including constant polynomials (degree 0), linear polynomials (degree 1), quadratic polynomials (degree 2), and so on. Adding and subtracting polynomials is the process of combining two or more polynomials by combining like terms. Like terms are terms with the same variable and exponent. To add or subtract polynomials, simply line up the terms with the same variable and exponent and add or subtract the coefficients. The result will be a new polynomial with the combined terms.

For example, to add the polynomials [tex]2x^2 + 3x + 4[/tex] and [tex]-x^2 + 5x - 6[/tex], we line up the terms with the same variable and exponent and add the coefficients:

[tex](2x^2 + 3x + 4) + (-x^2 + 5x - 6) = (2x^2 - x^2) + (3x + 5x) + (4 - 6) \\[/tex]

                                                   [tex]= x^2 + 8x - 2.[/tex]

So, if Octavio scores 10 points higher than the class mean on the midterm, we may anticipate that he will score final = a + b * (x + 10) points higher on the final.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

Given the regression equation for predicting final-exam score from midterm-exam score:

final = a + b * midterm

where a and b are the regression coefficients, we can use the class mean midterm score x as a reference point to predict the final exam score for a student who scored 10 points above the class mean on the midterm.

First, we need to find the class mean midterm score, which can be represented as x:

x = mean(midterm_scores)

Next, we find the predicted final exam score for the class mean midterm score:

final = a + b * x

Finally, we find the predicted final exam score for a student who scored 10 points above the class mean midterm score:

final = a + b * (x + 10)

Marginal revenue and marginal profit when 2500 widgets are sold is $175 and $-17.5 respectively and when 7500 widgets are sold is $125 and $-207.5 respectively.

The cost function is given by:

C(x)\ =\ 15000\ +\ 100x\ -\ 0.03x^2\ +\ 0.000004x^3

The demand function is given by:

p\left(x\right)=200-0.005x

The marginal revenue and marginal profit are determined by differentiating revenue function R(x) and profit function P(x) respectively. The relationship between cost function C(x), revenue function R(x) and profit function P(x) is:

P(x)\ =\ R(x)\ -\ C(x)

The revenue function is determined by multiplying demand function p(x) and number of widgets x, hence

R(x)\ =xp(x)\ =\ x(200\ -\ 0.005x)\ =\ 200x\ -\ 0.005x^2

The profit function is given by:

P(x)\ =\ (200\ -\ 0.005x^2)\ -\ (15000\ +\ 100x\ -\ 0.03x^2\ +\ 0.000004x^3)

P(x)\ =\ -0.000004x^3\ -\ 0.025x^2\ +\ 100x\ -\ 15000

Differentiating profit function to determine marginal profit:

P\left(x\right)=-0.000004x^3-0.025x^2+100x-15000

P'(x)\ =\ -0.0000012x^2\ -\ 0.05x\ +\ 100

Differentiating revenue function to determine marginal revenue:

R(x)\ =\ 200x\ -\ 0.005^2

R'(x)\ = 200 – 0.01x

Evaluating these differentials when x = 2500 and x = 7500

P'(x)\ =\ -0.0000012x^2\ -\ 0.05x\ +\ 100

P'(2500)\ =\ -0.0000012(2500)^2\ -\ 0.05(2500)\ +\ 100\ =\ -17.5

P'(7500)\ =\ -0.0000012(7500)^2\ -\ 0.05(7500)\ +\ 100\ =\ -207.5

R'(x)\ = 200 – 0.01x

R'(2500)\ = 200 – 0.01(2500) = 175

R^\prime\left(7500\right)=200-0.01\left(7500\right)=125

Hence, marginal revenue and marginal profit when 2500 widgets are sold is $175 and $-17.5 respectively and when 7500 widgets are sold is $125 and $-207.5.

The value of the sample variance rounded to one decimal place is 76.0.

What is the Mean?

The mean is a measure of the central tendency of a set of data, calculated as the sum of the values divided by the number of values in the set.

The sample variance of a set of data is a measure of the spread or dispersion of the data around the mean. To calculate the sample variance, you can follow these steps:

Calculate the mean of the data: First, find the sum of all the data points and divide by the number of data points (n).

For the given data, the mean is: (-11 + -5 + -5 + -11 + 13 + -11 + -5) / 7 = -7

Subtract the mean from each data point: Next, subtract the mean from each data point to get the deviations from the mean.

For the given data, the deviations are: (-11 - -7) = -4, (-5 - -7) = 2, (-5 - -7) = 2, (-11 - -7) = -4, (13 - -7) = 20, (-11 - -7) = -4, (-5 - -7) = 2

Square the deviations: Square each deviation to get rid of negative values.

For the given data, the squared deviations are: (-4)^2 = 16, (2)^2 = 4, (2)^2 = 4, (-4)^2 = 16, (20)^2 = 400, (-4)^2 = 16, (2)^2 = 4

Sum the squared deviations: Sum all the squared deviations.

For the given data, the sum of the squared deviations is: 16 + 4 + 4 + 16 + 400 + 16 + 4 = 456

Divide the sum by n - 1: Finally, divide the sum of the squared deviations by the number of data points minus 1 (n - 1). This gives us the sample variance.

For the given data, the sample variance is: 456 / (7 - 1) = 456 / 6 = 76

Hence, the value of the sample variance rounded to one decimal place is 76.0.

Probability that more than 10 adults in the sample have hypertension is 0.768

Var(X) = 5.25

The probability that more than 10 adults in the sample have hypertension is 0.6086

The National and Nutrition survey reported that 30% of adults in the U. S have hypertension (high blood pressure). Let X be the number of adults in the U. S with hypertension.

A sample of 25 adults is studied:

Calculate the following probabilities using R guro and then fill in the blanks with your answers.

a) The probability that 12 or fewer adults in the sample have hypertension is  . Round your answers to three decimal places.

b) The probability that more than 10 adults in the sample have hypertension is  . Round your answers to three decimal places.

c) Calculate the Var(X)=n ∗p∗(1−p) = . Round the answer to the nearest whole number.

The proportionate equation for each problems are:

Let's discuss each problem we have:

1. Liv earns $9.50 for every 2 bracelets she sells.

y = 4.75x

because y = kx, then:

y = $9.50

x = 2

4.75 --> constant of proportionality

--> price per unit of bracelet sold

2. John ran 3 miles in 25.5 minutes

y = 8.5x

y = 25.5 minutes

x = 3 miles

8.5 --> constant of proportionality

--> minuntes per miles

--> times per distance

3. Lincoln bought 3 bottles of energy drink for $4.50

y = kx

y = $4.50

x = 3

$4.50 = k (3)

k = $1.50 --> price of a bottle of energy drink

4.  Total cost of 4 hours renting a cotton candy machine is $72.

y = kx

y = $72

x = 4 hours

$72 = k(4)

k = $18 --> price of renting per hour

5. 7 cups of water are used to make 4 loaves of French bread.

y = kx

y = 7

x = 4

7 = k(4)

k = 7/4

Proportionate equation: y = 7/4 x

(x = 6)

y = 7/4 (6)

y = 21/2 = 10.5 cups of water

6. 6 3/4 yards of fabrics are used to make 3 elf costumes

y = kx

y = 6 3/4

x = 3

6 3/4 = k (3)

27/4 = 3k

--------------- x 4

27 = 12k

k = 9/4

Proportionate equation: y = 9/4 x

(x = 7)

y = 9/4 (7)

y = 63/4

y = 15 3/4 yards of fabric
