The regression equation is Y = 95.0 + 0.84X.The regression line is a mathematical model that is used to predict the value of a dependent variable (Y) based on the value of an independent variable (X).

In this case, the regression line is used to predict Y from X using the following data: X = 10, 20, 30, 40, 50, 60 and Y = 111, 109, 110, 94, 92, 93. By using a regression analysis tool such as StatKey, we can calculate the regression equation that best fits this data. The regression equation is Y = 95.0 + 0.84X, where 95.0 is the intercept and 0.84 is the slope. This equation can be used to make predictions about the value of Y for a given value of X. The rounded answer for the intercept is 95.0 and the rounded answer for the slope is 0.84.

To illustrate this further, we can break down the long division process into steps. First, divide 2x² into 8x²³.

The result is 4x².

Then, subtract 4x² from 8x²³ to get the remainder of 4x³.

Next, divide 4x² into 21².

The result is 33x.

Then, subtract 33x from 4x³ to get the remainder of 4x²-33x.

Finally, divide 4x²-33x into 67x.

The result is 12. Subtract 12 from 4x²-33x to get the remainder of 2x²-x-21.

This remainder is the expression which represents the quotient and remainder, written as partial fractions, of 8x²³-21²-67x-24.

A supernova is a powerful and luminous explosion of a star, which is what the sun is.

Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

The formula y=mx+b is used to draw a simple regression graph. The inclination is B, and the y-intercept is m. It is frequently referred to simply as a "simple method combining many variables," despite the fact that the section before it is divided into distinct sections. Bivariate linear equations have two variables. For problems involving linear equations in applications, there are no proven solutions. Y=mx+b, also known as mx+b, provides a number of straightforward formulae.

Here,

Using the distance formula:

sqrt((x - 11)^2 + (-9 - 6)^2) = 17

Simplifying:

sqrt((x - 11)^2 + 225) = 17

Squaring both sides:

(x - 11)^2 + 225 = 289

(x - 11)^2 = 64

Taking the square root:

x - 11 = ±8

x = 11 + 8 or x = 11 - 8

x = 19 or x = 3

Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

Answer:

B. 9[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Rewriting the two fractions in the expression:

=[tex]\frac{[(8)(2)]+1}{8} + \frac{[(8)(7)]+3}{8}[/tex]

=[tex]\frac{17}{8} + \frac{59}{8}[/tex]

Since the denominators of both the fractions is the same, then the denominator of the resulting simplified fraction will also be the same. In addition, everything written in the numerator level will be copied down as it is:

=[tex]\frac{17 + 59}{8}[/tex]

=[tex]\frac{76}{8}[/tex]

Divide the numerator and denominator by the Highest Common Factor '4':

= [tex]\frac{19}{2}[/tex]

Apply Long Division since:

Choose the highest quotient to be multiplied by 2 to give a number closest to 19 but still less than 19. The quotient turns out to be 9. The remainder is 1

∴ Sum of the expression = 9[tex]\frac{1}{2}[/tex]

2x(5x + 1) / (4x - 1) is the final expression.

Option D is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(4x³ - 12x²) / (4x² + 7x - 2) / (2x² - 6x) / (5x² + 11x + 2)

= (4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)

Now,

(4x³ - 12x²) = 4x² (x - 3) _____(1)

And,

(5x² + 11x + 2)

Middle term factorizing

= 5x² + (10 + 1)x + 2

= 5x² + 10x + x + 2

= 5x (x + 2) + 1(x + 2)

= (x + 2) (5x + 1) ______(2)

And,

(4x² + 7x - 2)

Middle term factorizing

= 4x² + (8 - 1)x - 2

= 4x² + 8x - x - 2

= 4x(x + 2) - 1(x + 2)

= (4x - 1) (x + 2) ______(3)

And,

(2x² - 6x) = 2x (x - 3) ______(4)

From (1), (2), (3), and (4) we get,

(4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)

= [ 4x² (x - 3) x (x + 2) (5x + 1) ] / [ (4x - 1) (x + 2) x 2x(x - 3) ]

(x + 2) and (x - 3) gets canceled.

= [4x² (5x + 1)] / [(4x - 1) 2x]

= 2x(5x + 1) / (4x - 1)

Thus,

Step-by-step explanation:

All other things being equal, outliers tend to have a greater effect on the value of the mean, as compared to the value of the median. The given statement is true.

What is the mean and median?

Outliers are values that are significantly different from the other values in a data set, and their presence can greatly affect the value of measures of central tendency, such as the mean and the median.

The mean is a measure of central tendency that is calculated as the sum of all the values in a data set divided by the number of values. The presence of outliers can greatly affect the mean because outliers can have a large impact on the sum of the values in the data set. For example, if a data set has a few very large outliers, the mean will be pulled up to be much higher than the median, which represents the midpoint of the data set.

On the other hand, the median is a measure of central tendency that is calculated as the middle value of a data set when the values are arranged in order. The median is not as sensitive to outliers as the mean because outliers do not affect the median unless the number of outliers is so large that it changes the value of the middle value.

Hence, all other things being equal, outliers tend to have a greater effect on the value of the mean than on the value of the median.

The two angles are 32 degrees and 48 degrees.

Step-by-step explanation:

If one angle of a triangle is 100 degrees, then the sum of the other two angles is 80 degrees (180 - 100). If the magnitude of the other two angles is in the ratio 2:3, then we can call the first angle 2x and the second angle 3x. The sum of these two angles is 5x, so 5x = 80, and x = 16. So, the two angles are 2x = 32 degrees and 3x = 48 degrees.

The Point-Slope equation is Z = 15X - 19Y + 204.

What is the slope-point form?

The slope-point form of a line in 3-dimensional space is a equation of the form:

Z = m_x (X - X_0) + m_y (Y - Y_0) + Z_0

where (X_0, Y_0, Z_0) is a point on the line, m_x is the x-slope, and m_y is the y-slope.

Given:

point (2, -12, 4) and x-slope 15 and y-slope -19, we can use the point-slope form to find the equation of the plane:

Z = 15 (X - 2) - 19 (Y + 12) + 4

Hence, the point-slope equation of the plane passing through the point (2, -12, 4) and having x-slope 15 and y-slope -19 is:

The optimum sampling strategy is (iii), which is listed below.

By selecting a student's initial name from each page of the cam pus phone book, you may measure the heights of the chosen pupils.

Sampling is a technique for selecting a small group of people or a subset of the population in order to make generalizations and estimate the features of the population. In order to acquire relevant information without studying the entire society, researchers commonly use a variety of sampling approaches in market research.

To ascertain the average height of all students at a certain institution and guarantee that the result is statistically reliable, the sampling process must be applied.

a. Measure the heights of 50 students found in the gym during basketball intramurals.

This approach is not ideal since you would only sample basketball players while leaving all other university students out; hence, your sample would not be representative of all students, simply those who play basketball.

b. Measure the heights of all engineering majors.

This approach is flawed since the sample exclusively includes engineering majors, leaving out students studying other courses.

c. Measure the heights of the students selected by choosing the first name on each page of the campus phone book.
