Part 1

\(m\angle AOB=m\angle BOC\)

Part 2

Since \(m\angle AOB=m\angle BOC\) from part 1, we know that since \(m\angle AOB=53^{\circ}\), by the transitive property of equality, \(m\angle BOC=53^{\circ}\).

Part 3

\(m\angle AOC=m\angle AOB+m\angle BOC=53^{\circ}+53^{\circ}=106^{\circ}\)

Given that Juan bought a car for $32,500, and the function f(x) expressed as

is the value of the car in any given year as shown in the table below:

From the above table, Juan bought the car in 2009.

Thus, to evaluate the approximate value of the car in 2020,

step 1: Evalaute the value of x.

In 2020, the value of x from 2009 will be

thus,

step 2: substitute 11 for the value of x into the f(x) function.

thus,

Hence, the approximate value of the car in 2020 is

The correct option is B.

Answer:

The first option

The linear equation doesn't have a solution.

The linear equation given is illustrated as: 4x-(2x-1) = x+5+x-6

This will be solved thus:

4x - 2x + 1 = x+5+x-6

4x - 2x + 1 = 2x - 1.

2x + 1 = 2x - 1

Collect like terms

2x - 2x = -1 - 1

0 = -2

This illustrates that the equation doesn't have a solution.

The probability that no more than 13 of the tickets have popcorn coupons is 0.1114.

It is a binomial distribution "DISCRETE probability distribution that encapsulates the likelihood that a value will take one of two independent values when a particular set of conditions is met. The assumptions for the binomial distribution are that each trial has a single possible outcome, each trial has an equal chance of success, and each trial is independent of the others or mutually exclusive ".

Let X the random variable of interest, on this case we now that:

X ∼ Binom( n = 18, p = 0.97)

The probability mass function for the Binomial distribution is given as:

P( X ) = ( ₙCₓ )(p)ˣ( 1 - p )ⁿ⁻ˣ

Where (ₙCₓ) means combinatory and it's given by this formula:

ₙCₓ = n! / ( n - x )! x!

And we want to find this probability:

P( X = 13 )

And using the probability mass function we got:

P( X = 13 ) = ₁₈C₁₃ ( 0.597 )¹³ ( 1 - 0.597 )¹⁸⁻¹³

P( X = 13 ) = 8568 × 0.00122367561 × 0.01062980336

P( X = 13 ) = 0.11144766975

Answer:

Step-by-step explanation:

A rational number are number that can be written as the ratio of two integers. Integers are whole numbers and they can be positive or negative including zero.

Looking at the value 5.371, we can write it in fraction form as shown;

5.371 = 5371/1000

Since 5.371  is equivalent to 5371/1000 and 5371/1000 is a ratio of two integers 5371 and 1000 therefore we can conclude that 5.731 is a rational number

Note that decimal numbers are not integers and are not whole numbers.

Given:A point is (8, 0, 9) and Plane equation is x - y + z = 4. The minimum distance from the point (8, 0, 9) to the plane x - y + z = 4.We know that the shortest distance from a point to a plane is along the perpendicular.

Let the point P(8, 0, 9) and the plane is x - y + z = 4. Then a normal vector n to the plane is given by the coefficients of x, y and z of the plane equation, i.e., n = (1, -1, 1).Therefore, the equation of the plane can be written as (r - a).n = 4, where r = (x, y, z) and a = (0, 0, 4) is any point on the plane.Substituting the values, we have (r - a).n

\(= ((x-8), y, (z-9)).(1, -1, 1) = (x-8) - y + (z-9) = 4So, (x-8) - y + (z-9) = 4x - y + z - 21 = 0\)

Now, the distance from the point P to the plane can be given by:Distance d =  |(P - a).n| / |n|where |n| = \(√(1^2 + (-1)^2 + 1^2) = √3Then, d = |(8, 0, 9) - (0, 0, 4)).(1, -1, 1)| / √3= |(8, 0, 5)).(1, -1, 1)| / √3= |8(1) + 0(-1) + 5(1)| / √3= 13 /\)√3 Since the denominator √3 is less than 2, then the numerator is greater than 13*2=26. This means that d > 26. Hence the minimum distance from the point (8, 0, 9) to the plane x - y + z = 4 is greater than 26 or more than 100.

1. Average of the entire data set: 15.47 ounces

  Standard deviation of the entire data set: 1.51 ounces

2. American League:

  Average of drink sizes: 16.8 ounces

  Standard deviation of drink sizes: 2.26 ounces

1. Computing the average and standard deviation of the entire data set:

  Average = (14 + 18 + 20 + 16 + 16 + 12 + 14 + 16 + 14 + 16 + 16 + 16 + 14 + 32 + 16 + 20 + 12 + 16 + 20 + 12 + 16 + 16 + 24 + 16 + 16 + 14 + 14 + 12 + 14 + 20) / 30

          = 464 / 30

          ≈ 15.47 ounces

  Standard deviation = √[((14 - 15.47)² + (18 - 15.47)² + (20 - 15.47)² + ... + (14 - 15.47)²) / 30]

                    ≈ √(68.71 / 30)

                    ≈ √2.29

                    ≈ 1.51 ounces

2. Computing the average and standard deviation for the American League and the National League:

  American League:

  Average (AL) = (14 + 18 + 20 + 16 + 16 + 12 + 14 + 16 + 14 + 16 + 16 + 16 + 14 + 32 + 16) / 15

               = 252 / 15

               ≈ 16.8 ounces

  Standard deviation (AL) = √[((14 - 16.8)² + (18 - 16.8)² + (20 - 16.8)² + ... + (32 - 16.8)²) / 15]

                         ≈ √(76.8 / 15)

                         ≈ √5.12

                         ≈ 2.26 ounces

  National League:

  Average (NL) = (20 + 12 + 16 + 20 + 12 + 16 + 16 + 14 + 14 + 12 + 14 + 20) / 15

               = 200 / 15

               ≈ 13.33 ounces

  Standard deviation (NL) = √[((20 - 13.33)² + (12 - 13.33)² + (16 - 13.33)² + ... + (20 - 13.33)²) / 15]

                         ≈ √(40 / 15)

For the number of miles driven, Company A will charge less than Company B if x<y, where x is the number of miles driven for Company A and y is the number of miles driven for Company B. Therefore, the inequality is x<y.

When comparing two companies for their charges for a specific service, it is necessary to obtain a basic understanding of the charges for each company. You can make use of the inequality operator to check when one company will charge less than the other company.

To use the inequality operator, you'll need to calculate the differences between the two companies for the specific mileage. Let's assume that the mileage is represented by "m" and that the charge for company A is "cA" and the charge for company B is "cB".

If the question only provides specific numerical values for these variables, you can substitute them into the inequality formula. If you're given algebraic expressions, you'll need to simplify them before substituting them into the inequality formula.

The inequality formula for comparing the charges is as follows: cA < cB.

To use this formula, substitute the expression for each variable.

For example: 4m + 20 < 3.5m + 35 Now, you'll need to simplify the inequality by performing algebraic operations on both sides of the inequality. Begin by subtracting 3.5m from both sides of the inequality: 0.5m + 20 < 35.

Next, subtract 20 from both sides of the inequality: 0.5m < 15 Finally, divide both sides of the inequality by 0.5: m < 30

Therefore, Company A will charge less than Company B for any mileage less than 30.

The company owns five vans which is determined by the equation method.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We can set up the following system of equations to represent the given information:

s + v = 12

3s + 8v = 61

where s represents the number of sedans and v represents the number of vans.

We can solve this system of equations using substitution.

First, we can solve the first equation for s:

s = 12 - v

We can substitute this expression for s in the second equation to get:

3(12 - v) + 8v = 61

Solving for v, we get:

36 - 3v + 8v = 61

Combining like terms, we get:

5v = 25

Dividing both sides by 5, we get:

v = 5

Therefore, the company owns 5 vans.

The fact that column B contains 100 observations of a string variable means that the column has a length of 100, and each value in the column is a string.

If column B contains 100 observations of a string variable, then it is true that the column B has a length of 100. This means that there are 100 different values in the column, each one being a string. A string variable is a type of data that is used to represent text, and can include letters, numbers, and symbols.

In addition, it is also true that each observation in column B is a string. This means that each value in the column is a text value, and not a numerical value. It is important to remember that string variables are used to store text data, while numerical variables are used to store numbers.

Overall, the fact that column B contains 100 observations of a string variable means that the column has a length of 100, and each value in the column is a string.

The value of (x - y)(x - y), if xy = 3 and x² + y² = 25, is 19.

A binomial is an expression represented by the sum or a difference of two algebraic terms. Generally, we can express it as a+b. If we square this binomial, (a + b)², it can be expanded into a² + 2ab + b².

xy = 3

x² + y² = 25

Now,  (x - y)(x - y) = x² + y² -xy -xy

(x - y)(x - y) = x² + y² -2xy

Now put the values of x² + y² and xy
