Step-by-step explanation:

The linear distance traveled in one revolution of a wheel can be calculated using the formula:

Circumference = π * Diameter

Given that the diameter of the wheel is 36 inches, we can substitute the value into the formula:

Circumference = π * 36 inches

Using an approximate value of π as 3.14159, we can calculate the circumference:

Circumference ≈ 3.14159 * 36 inches

Circumference ≈ 113.09724 inches

Therefore, the linear distance traveled in one revolution of a 36-inch diameter wheel is approximately 113.09724 inches.

Answer:

$44.80

Step-by-step explanation:

Here' s  an equation to help you with percent problems:    part            %

                                                                                               -------    =    -----

                                                                                              whole         100

Because you want to find 12%, the % in the equation would be replaced with 12. The part would be x because that's what u need to find. The whole would be 40. Cross multiply to get 100x = 480. Divide 480 by 100 to get x = 4.80. Add 4.80 to 40.00 to get the final price. The final price is $44.80.

Answer: she must complete 4 levels to have a point fewer than 20

Step-by-step explanation:

Given the following :

Starting point = 100 points

Passing a level = - 8 points

Catching a flower = - 3 points

Suppose Tina catches 6 flowers per level

Number of levels she must complete to have fewer Than 20 points

Total number of points lost per level:

Catching 6 flowers = -(6 × 3)

Passing the level = - 8

= - 18 + - 8 = - 26 points

Number of levels she must complete to have < 20

Let number of levels = y

Starting points - (26 × number of levels) < 20

100 - (26y) < 20

100 - 26y < 20

-26y < 20 - 100

-26y < - 80

y > 80/26

y > 3.07

Hence she must complete 4 levels to have a point fewer than 20

Partial initialization allows us to initialize only some elements of an array, leaving the rest with default values.

The statement you provided, `int num]= (88, 92, 75, 95, 82)`, contains syntax errors and is not a valid example of partial initialization of an array in C or C++.

To understand partial initialization of an array, let's consider a correct example. Suppose we have an integer array named `num` with a size of 10. We want to initialize the first five elements of the array with specific values, and the remaining elements should be set to 0. Here's how partial initialization would look like:

int num[10] = {88, 92, 75, 95, 82};

In this example, we declare an integer array `num` with a size of 10. We provide an initializer list inside curly braces `{}` to initialize the elements of the array. The first five elements are explicitly initialized with values `88`, `92`, `75`, `95`, and `82`. The remaining elements are automatically set to 0 because we haven't provided explicit values for them.

Partial initialization allows us to initialize only some elements of an array, leaving the rest with default values. It's particularly useful when we want to set certain values while keeping others as defaults, such as zero in the case of integers.

At least 88.9% of the quiz scores in a beginning statistics class will reside within the range of 6.3 to 8.7, without rounding.

SOLUTION:

By using Chebyshev's Therem.

Chebyshev's Theorem states that for any dataset, the proportion of data within k standard deviations from the mean is at least (1 - 1/k^2).

Step 1:

Calculate the value of k.
Since we want at least 88.9% of the data within the range,

we can set up the equation as follows:

(1 - 1/k^2) ≥ 0.889

Solving for k:
1 - 0.889 = 1/k^2
0.111 = 1/k^2
k^2 = 1/0.111
k ≈ 3

Step 2:

Calculate the range using the value of k, mean, and standard deviation.
Lower Bound = Mean - k * Standard Deviation
Upper Bound = Mean + k * Standard Deviation

Lower Bound = 7.5 - (3 * 0.4) = 7.5 - 1.2 = 6.3
Upper Bound = 7.5 + (3 * 0.4) = 7.5 + 1.2 = 8.7

Using Chebyshev's Theorem, at least 88.9% of the quiz scores in a beginning statistics class will reside within the range of 6.3 to 8.7, without rounding.

15(x-3)/5 you will distribute the 15 to the x and the -3

15x-45/5 you will divide 5 to both the 15x and the 45

3x-6x=9-9 solve

-3x=0 divide

-3x=0 /-3 (all of it will be divided by 3 cuz what you do to one side, you gotta do to the other)

x=0

without distributive property

15(x-3)/5=3(2x-3) remove the parenthesis from the left side

3(x-3)=3(2x-3) distribute the 3 through the parenthesis on both sides

3x-9=6x-9 the rest is the same as in the combined section up above.

The ending balance in accumulated other comprehensive income on December 31, 2019, is $10,200 (credit balance).

To determine the ending balance in accumulated other comprehensive income on December 31, 2019, we need to analyze the changes in comprehensive income and other comprehensive loss. The net income of $12,000 and other comprehensive loss of $3,000 (net of tax) for the year ended December 31, 2020, indicate that the comprehensive income for the year is $9,000 ($12,000 - $3,000).

The ending balance in accumulated other comprehensive income can be calculated by adding the comprehensive income for the year to the beginning balance in accumulated other comprehensive income. Given that the ending balance on December 31, 2020, is $6,800 (credit balance), we can derive the beginning balance in accumulated other comprehensive income on December 31, 2019, by subtracting the comprehensive income for the year ($9,000) from the ending balance on December 31, 2020.

This equation, yt = α0 + yt-1 + et, is an autoregressive model of order one. This model is also known as an AR(1) model.

Consider the following random walk process: yt = α0 + yt-1 + et, t = 1, 2, ... where {et: t = 1, 2, ...} is i.i.d. with a mean of zero and variance of σ²e. In the equation for the random walk, the value of y_t depends on its previous value y_{t-1} plus a new term e_t. Here, α0 represents the constant or intercept term. The errors e_t are considered to be independent and identically distributed (i.i.d.) with a mean of zero and variance of σ²e.A random walk is a type of time series model that describes the random fluctuations of a variable over time. It is said to be a stochastic process because its future values cannot be predicted with complete accuracy. Instead, the future values of a random walk are probabilistic and are influenced by the current and past values of the series. The random walk model is widely used in finance to model stock prices and exchange rates. It is also used in physics and chemistry to model the random motion of particles.

The random walk process is useful in time series analysis because it is a simple model that can be used to generate forecasts. It is also useful for testing the hypothesis of a random walk. If the random walk hypothesis is true, then the value of y at any point in time should be equal to the value of y at the previous point in time plus a random error. If the hypothesis is not true, then the value of y at any point in time should be influenced by other factors.

A random walk is a process in which future values are obtained by adding the value of the current period to a random error term. The current period value is not directly observable, and it can be approximated by taking the difference between the value in the current period and the value in the previous period. The model is:yt=α0+yt−1+et, t=1,2,….Here, {et:t=1,2,…} is i.i.d with a mean of zero and variance of σe2.The general equation for the random walk is:yt=yt−1+etwhere α0 is usually set to zero. This means that the value of y at any point in time is equal to the sum of the value of y at the previous point in time plus a random error. The value of y at the first point in time is unknown. We call the random walk process "nonstationary" because the variance of y increases over time.If we take the difference between the value of y at two points in time, we get:yt−yt−1=etThis is called the first difference of y. If we take the second difference of y, we get:(yt−yt−1)−(yt−1−yt−2)=et−et−1which is equal to:yt−2yt−1=et−et−1This means that the second difference of y is equal to a new error term that is created by subtracting two consecutive error terms. The second difference of y is called the "seasonal difference."When we take the first difference of y, we get a new series called the "first difference." If we take the second difference of y, we get a new series called the "second difference." In general, if we take the nth difference of y, we get a new series called the "nth difference."

Consider a rectangular plate with dimensions a x b, where the left side is kept at zero degrees Celsius, the right side is well insulated, the bottom is also maintained at zero degrees Celsius, and the top side has a specified temperature distribution given by f(x). We are tasked with finding the temperature distribution across the plate.

To determine the temperature distribution across the rectangular plate, we need to solve the heat conduction equation or the Laplace equation, depending on the specific conditions and boundary conditions of the problem.

The heat conduction equation is a partial differential equation that describes how heat flows within a medium. In this case, we will need to consider the two-dimensional heat conduction equation to account for the temperature variation in both the x and y directions of the plate.

However, to provide a more detailed explanation and specific solution, we would require additional information, such as the functional form of f(x) and the specific boundary conditions (if any) on the sides of the plate. These details are crucial in formulating and solving the appropriate mathematical model for temperature distribution.

Using subtraction of normal variables, it is found that there is a 0.5704 = 57.04% probability that their scores are within 10 points of each other.

In a normal distribution with mean and standard deviation, the z-score of a measurement X is given : Z = (X - )/

It determines how far the measure deviates from the mean.

We look at the z-score table after determining the z-score to determine the p-value, which is the percentile of X.

The mean is calculated by subtracting the means of two normal variables, whereas the standard deviation is calculated by taking the square root of the sum of the variances.

How to solve the question?

Two variables from the same population, with mean 41, are subtracted, hence the mean of the distribution of the subtraction is μ = 41-41 = 0

For each variable, the standard deviation is of 9, hence the standard deviation of the distribution of the subtraction is σ = √9² +9² = 12.73

The probability that their scores are within 10 points of each other is the probability that the subtraction is between -10 and 10, that is, the p-value of Z when X = 10 subtracted by the p-value of Z when X = -10.

X = 10:

Z = (X - μ)/σ = 0.79 has a p-value of 0.7852.

X = -10:

Z = (X - μ)/σ = - 0.79 has a p-value of 0.2148.

0.7852 - 0.2148 = 0.5704.

Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations. This implies that the simultaneous equations have a common solution.

We use different methods to solve simultaneous equations. Some of the common methods are:

By substitution method

-7x + -5y = 15 ----- 1

7x + 3y = 12 ----- 2

from equation 1

7x = -15 -5y ----- 3

substitute 7x in equation 2

-15 - 5y + 3y = 12

-2y = 12 + 15

-2y = 27

y = -27/2

To find x, substitute y in equation 3

7x = -15 - 5(-27/2)

7x = -15 + 135/2

Multiplying both sides by 2

How to find the Z score

P(Z ≤ z) = 0.60

We can use a standard normal distribution table or a calculator to find that the z-score corresponding to a cumulative probability of 0.60 is approximately 0.25.
