n = -8

Answer:

Step-by-step explanation:

adding all the angles then equate it to 180

x-5+2x+2x-10=180

5x-15=180

5x=195

x=39

to check, plugin x which is 39 into the given angles.

like, 39-5=34 and 2(39)=78 and 2(39)-10= 68

and all of this must be equal to 180 because the angle in a triangle is always 180 degrees.

So, 34+78+68=180

According to the given information, the distance traveled by an object is directly proportional to the amount of time spent traveling. If an object travels for 6 hours and covers a distance of 933 miles, we can determine the distance it would cover in 9 hours and covers a distance of 1399.5 miles.

To solve this problem, we can set up a proportion based on the given information. Let's assume that "x" represents the distance traveled in 9 hours.

According to the problem, we know that the distance traveled is directly proportional to the amount of time spent traveling. Mathematically, this can be expressed as:

Distance / Time = Constant

Using the values provided, we can set up the proportion as follows:

933 miles / 6 hours = x miles / 9 hours

Now, we can cross-multiply and solve for "x":

(933 miles) * (9 hours) = (6 hours) * (x miles)

8397 miles = 6x

Dividing both sides of the equation by 6, we get:

x = 8397 miles / 6

x ≈ 1399.5 miles

Therefore, the object would travel approximately 1399.5 miles when traveling for 9 hours (rounded to the nearest hundredth).

To determine the percentage of women in a sample with a master's degree using Excel, you need to follow:

First, make sure your data is organized in columns, with one column for gender and another for education level.

Next, use the filter feature in Excel to display only the rows where the gender is "Female" or "Woman". This will help isolate the data for women in the sample.

Then, focus on the education level column and filter it to show only the rows where the education level is "Master's Degree". This will narrow down the data to women with a master's degree.

Count the number of women with a master's degree by using the COUNTIFS function in Excel. Set the criteria to match "Female" or "Woman" in the gender column and "Master's Degree" in the education level column. This will provide the count of women with a master's degree.

Now, calculate the total number of women in the sample by using the COUNTIF function. Set the criteria to match "Female" or "Woman" in the gender column. This will give you the count of all women in the sample.

Finally, divide the count of women with a master's degree by the count of all women in the sample and multiply by 100 to obtain the percentage. This will represent the percentage of women in the sample with a master's degree.

By following these steps and adapting them to your specific dataset in Excel, you can determine the percentage of women in the sample with a master's degree.

Step-by-step explanation:

Hope I did it right, tell me if its wrong.

Answer:

Therefore, the volume of the cylinder is approximately 2,262.9 cubic centimeters.

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr^2h, where r is the radius of the base and h is the height of the cylinder.

Substituting the given values, we get:

V = π(6 cm)^2(20 cm)

V = 720π cm^3

To find the volume to the nearest tenth, we can use the approximation π ≈ 3.14 and calculate:

V ≈ 720(3.14) cm^3

V ≈ 2,262.8 cm^3

Rounding to the nearest tenth, we get:

V ≈ 2,262.8 cm^3 ≈ 2,262.9 cm^3

Therefore, the volume of the cylinder is approximately 2,262.9 cubic centimeters.

This is the total value of the coins in cents

To convert this to dollars, divide by 100. So the total value in dollars is (10d+5n+p)/100.

The three terms are

------------

Let's look at an example with actual numbers.

I picked three whole numbers at random.

So,

The total value is 10d+5n+p = 90+15+5 = 110 cents aka 110/100 = 1.10 dollars.

The least 3 digit of n is abc and N is a multiple of 8. If 4a+2b+c is divisible by 8, then N is also divisible by 8.

Given that least 3 digit of n is abc and N is multiple of 8.Let's write the number abc in terms of its place values.

Therefore,n = (a × 100) + (b × 10) + c

Now, we are given that N is a multiple of 8.

Therefore, (a × 100) + (b × 10) + c is a multiple of 8.

Let's express this condition in terms of divisibility rules of 8.

We know that if the last three digits of a number are a multiple of 8, then the entire number is also divisible by 8.

So, if the last three digits of n,

which is (a × 100) + (b × 10) + c, are divisible by 8,

then N is also divisible by 8.

Thus, (a × 100) + (b × 10) + c is divisible by 8.In other words,8 should divide (a × 100) + (b × 10) + c.

Remember that a, b, and c are digits from 0 to 9.

Let us see how we can use this information to calculate the answer.

Now, we need to check if 4a+2b+c is a multiple of 8 or not.i.e., 4a+2b+c should be divisible by 8 or 4(2a)+2b+c should be divisible by 8.

From the above expression, it is clear that 2b+c is always even.

Therefore, 2b+c should be equal to 0, 2, 4, 6, or 8 for 4(2a)+2b+c to be divisible by 8.

Now, if we know that 2b+c is one of these values, then we can easily check if 4(2a)+2b+c is a multiple of 8 or not.

The number of laps ran by Levi is given by the equation w = 4 laps

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Final answer:

The standard deviation from the method A is 2.87

The standard deviation from the method B is 1.35

The standard deviation from the method C is 0.42

The standard deviation from the method D is 0.75

The standard deviation reveals the degree of data skewedness. It gauges how far away from the mean each observed value is. Approximately 95% of values in any distribution will be within two standard deviations of the mean.

The statistical concept of standard deviation is used to quantify the variability or dispersion around an average. It is a measure of volatility technically. The discrepancy between the actual and average value is known as the dispersion. The standard deviation increases as the variability or dispersion increases.

A low standard deviation indicates that the data are tightly grouped around the mean, while a high standard deviation indicates that the data are widely dispersed (less dependable) (more reliable)

Explanation:

The highest standard deviation is found in procedure A. Given that it is not based on any actual measurements and is subject to wildly different subjective judgment, one would anticipate that it would be the largest.

Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables. It aims to find a linear equation that best fits the observed data points, allowing for the prediction of the dependent variable based on the independent variables.

In more detail, linear regression assumes a linear relationship between the dependent variable and the independent variables. The method estimates the parameters of the linear equation by minimizing the sum of the squared differences between the observed data points and the predicted values. This is typically done using a technique called ordinary least squares (OLS) regression. The resulting linear equation can be used to make predictions or infer the impact of the independent variables on the dependent variable.

Linear regression is widely used in various fields, including economics, finance, social sciences, and machine learning. It provides a simple and interpretable way to analyze and understand the relationship between variables. However, it is important to note that linear regression assumes certain assumptions about the data, such as linearity, independence of errors, and homoscedasticity. Violations of these assumptions can affect the accuracy and reliability of the regression model.

The intersecting chord theorem  states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.

Therefore, lets find the value of x in the intersecting chords as follows:
