Answer:

$25 is a fixed number, cannot be increased, decreased or deleted.

Step-by-step explanation:

In the situation, the math are modified by the fixed value of $25, which should be a addition to the variable term in the proper math expression.

The correct answers are Losing 12; Winning 15

Explanation:

The ratio of winning to losing is 5: 6 or 5/6. This means for every 5 winning spaces in the wheel there are 6 losing spaces. This ration should be used to complete the values of the table.

1. The first row shows there are 10 winning and you need to calculate the number of losing spaces. The process is shown below.

\(\frac{5}{6} = \frac{10}{x}\) - Express the ratios using fractions; use x to show the missing value

\(5x = 60\) - Cross multiply to find the value of x

\(x = 60 / 5\) - Solve the equation to find x

\(x = 12\) - The number of losing is 12 if there are 10 winning spaces

2. The second row shows there are 18 losing spaces, and you need to calculate the number of winning spaces. Repeat the process.

\(\frac{5}{6} = \frac{x}{18}\)

\(6x = 90\)

\(x = 90 / 6\)

\(x =15\) - The number of winning spaces is 15 if there are 18 losing spaces

Answer:

\(\angle 1\) and \(\angle 3\) are vertical angles and are congruent (have the same measure).

Step-by-step explanation:

\(\angle 1\) and \(\angle 3\) represent a pair of vertical angles. They are opposite angles to two intersecting lines. Vertical angles are always congruent. None of the other answer choices are implied in the figure.

Given data is:True response: 62Negative test result: 46Total: 108

The probability that a randomly selected polygraph test subject was not lying is 0.574 because there is a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.

Let's find the probability of the random selected person from the given data, who is not lying.P (not lying) = P (true response) + P (negative test result)P (not lying) = 62/108 + 46/108= (62 + 46) / 108= 108 / 108= 1

The probability of a random selected person from the given data who is not lying is 1. Since the calculated probability is not equal to 0.430 which is for a negative test result, the result is not close to 0.430.

The difference between the probability of not lying and a negative test result is 0.574-0.430 = 0.144, which is greater than the absolute difference of 0.050.

To calculate the total payment Ashley made in 4 years, the interest amount she paid, the letters used in the formula, the interest rate, and the APK (Annual Percentage Rate - Simple), we need to analyze the given information.

(a) The total payment Ashley made in 4 years can be found by multiplying the monthly payment ($447) by the number of installments (48). Total payment = $447 * 48 = $21,456.

(b) The interest amount Ashley paid can be calculated by subtracting the cost of the car ($18,000) from the total payment. Interest amount = Total payment - Cost of car = $21,456 - $18,000 = $3,456.

(c) The letters used in the formula can be identified as follows: A stands for the total payment, P stands for the monthly payment, N stands for the number of installments, and I stands for the interest amount.

(d) To find the interest rate, we need more information. The given data does not provide the necessary details to directly calculate the interest rate.

(e) The APK (Annual Percentage Rate - Simple) formula, as mentioned, is not clear. It seems to be a combination of different variables, but without further information, it cannot be calculated.

In conclusion, Ashley made a total payment of $21,456 in 4 years, paid an interest amount of $3,456, and the letters used in the formula are A, P, N, and I. The interest rate and the calculation of APK cannot be determined with the given information.

because the expression is raised to a power, you're going to multiply the power inside the expression with the power outside the expression. Thus:

\( \frac{10 ^{20} }{10^{12} } \)

Since the powers are being divided, you can just subtract 20 by 12. Then you would get:

The probability that Miguel will choose an FM radio station is 0.107.

The likelihood of an event occurring is measured using probability. We can calculate the likelihood of a neighbourhood fire, a region flood, or a product purchase, for instance.

An event's probability can be determined by counting all of its occurrences and dividing that number by the total number of ways the event could occur.

probability = occurrences / (non-occurrences + occurrences)

The assigned probability is always a fractional value that falls between 0 and 1, where 1 denotes full probability and 0 denotes no probability. The probability value one is equal to the probability that all possible events will occur.

The numbers can be arranged 6 times in a 2-by-3 grid.

The numbers can be arranged only six times since each row and each column has their numbers in increasing order.

The collection of whole numbers and negative numbers is known as an integer in mathematics. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions.

On integers, we can carry out all mathematical operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer.

The elementary row operation \(R_i - R_j\) can be used to manipulate the rows of a matrix and is a fundamental tool in the process of row reduction (also known as Gaussian elimination) for solving systems of linear equations and computing matrix inverses.

A matrix is a rectangular array of numbers or other mathematical objects arranged in rows and columns. Matrices are used in many areas of mathematics, as well as in physics, engineering, and computer science. The dimensions of a matrix are given by the number of rows and columns it contains. For example, a matrix with three rows and two columns is called a 3x2 matrix.

The entries of a matrix can be any mathematical object, but they are usually real or complex numbers. Matrices can be added and multiplied, which leads to many useful operations and applications. Matrix addition and multiplication are defined element-wise, meaning that the corresponding entries of two matrices are added or multiplied. Matrices can also be used to represent transformations of geometric objects, such as rotations, translations, and scaling.

Answer:

Length = 30

Width = 17

Step-by-step explanation:

Let L = length of rectangle and W = Width

The first sentence gives the equation

W = L/2 + 2 ==>

2W = L +4 ==>

L = 2W - 4 ....  (1)

The perimeter of the rectangle is 2(L+W) = 2L +2W

Second sentence gives us the equation

4L = 2L + 2W + 26 ===>
2L = 2W + 26 ......   (2)

(2) - (1) ==> L = 30   (2W cancels out)

From (1), W = 30/2 + 2 = 15 + 2 = 17

Check:
Using these values and substituting in equation 2 gives us
2 * 30 = 2* 17 + 26
60 = 34 + 26

The altitude of Polaris, also known as the North Star, refers to its angle above the horizon when observed from a specific location on Earth.

The altitude of Polaris varies depending on the observer's latitude.

For an observer at the North Pole (latitude 90 degrees), Polaris appears directly overhead, at an altitude of 90 degrees. This means Polaris is at the zenith, the highest point in the sky.

For observers at other latitudes in the Northern Hemisphere, Polaris will appear lower in the sky. The altitude of Polaris is equal to the observer's latitude. For example, if you are at a latitude of 40 degrees north, Polaris will have an altitude of approximately 40 degrees above the horizon.

It's important to note that the altitude of Polaris remains relatively constant throughout the night and throughout the year due to its proximity to the celestial north pole. This makes it a useful navigational reference point for determining direction and latitude in the Northern Hemisphere.
