In linear regression, the dependent variable is the outcome variable or the response variable that we want to predict or explain, while the independent variable is the predictor variable or explanatory variable that helps us in predicting the dependent variable.

The beta parameter and y-intercept are coefficients of the linear regression equation that help in determining the relationship between the dependent and independent variables.

Step-by-step explanation:

20.2% of trainees at the local mill earn less than 880.0 dollars a month.

The incomes of trainees at the local mill are normally distributed with a mean of 1210.0 dollars and a standard deviation of 140.0 dollars. This means that the distribution of incomes follows a normal curve, with most trainees earning close to the mean income of 1210.0 dollars, and fewer trainees earning significantly more or less than the mean.

To find the percentage of trainees earning less than 880.0 dollars a month, we can use the standard normal distribution table (also known as the z-table) to find the proportion of the distribution that is less than 880.0 dollars.

First, we need to convert the income of 880.0 dollars to standard units by subtracting the mean income and dividing by the standard deviation. This gives us (880.0 - 1210.0) / 140.0 = -1.29.

Next, we can look up the proportion of the standard normal distribution that is less than -1.29 on the z-table. This value is approximately 0.202, which means that approximately 20.2% of trainees at the local mill earn less than 880.0 dollars a month.

(x+6)(x+1)(x-4)

= (x^2 +x+6x+6)(x-4)

= (x^2+7x+6)(x-4)

= x^3 +3x^2 -22x-24

The simplified form of the expansion (x+6)(x-1)(x-4) is x³+x²-26x+24

Simplifying an expression is meant to add or subtract the like terms together.

Expansion of (a+b)(c+d) is given by

(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+bd

(x + 6)(x - 1)(x - 4)

=( x + 6){x(x - 4) - ( x - 4)}

=( x + 6 ){x² - 4x - x + 4}

=( x + 6 ){x² - (4+1)x + 4}

= ( x + 6 ){x² - 5x + 4}

= x{x² - 5x + 4} + 6{x² - 5x + 4}

= x³ - 5x² + 4x + 6x² - 30x + 24

= x³ + x² - 26x + 24

So, the simplified form of the expansion (x+6)(x-1)(x-4) is x³+x²-26x+24

May 2010 Gallup poll of 1029 US adults. When asked if they view divorce as “morally acceptable”,

If we use a 5% significance level, the p-value of 0.165 is not less than α = 0.05 so we would not

Answer:

Step-by-step explanation:

D. never

A parameter is a fixed value that represents a characteristic of a set population, such as the population mean or population proportion. It is a fixed value that is true for the entire population, it is calculated using all the data of the population. For example, the mean of the height of all adults in a country is a parameter. Since it is based on all the data, it is not an estimation, it is the true value of the population. Therefore, a parameter does not change, it is a fixed value for a set population.

The equation of line that passes through the point (6, -1) & is parallel to the line represented by 8x + 3y = 15, in standard form is: 8x + 3y = 45.

Equation of a line in standard form is:

Ax + By = C

where A, B & C are constants.

As the required line is parallel to the given line, that is 8x + 3y = 15, the slope of the required line will be same as that of the given line.

Slope intercept form of a line is:

y = mx + b

where, m is slope of the line, b is a constant.

Re-writing the equation of the given line in slope-intercept form:

⇒ 3y = -8x + 15

⇒ y = (-8/3)x + 5

⇒ slope = m = -8/3

Now as the required line is parallel to the given line, hence its slope-intercept form will be

y = (-8/3)x + b

As the line passes through the point (6, -1),

⇒ -1 = (-8/3)×6 + b

⇒ b = 15

Hence, the slope-intercept form of the required line is

y = (-8/3)x + 15

Re-writing it in standard form, the equation comes out to be

Step-by-step explanation:

To find the sum of the two expressions, we add the corresponding coefficients of each term:

(x - 5x^2 - 12) + (4 + 11x - 3x^2)

= x + 11x - 5x^2 - 3x^2 - 12 + 4

The another way to represent the diameter of an atom of gold is

1.44 x 10⁻⁷mm.

To change the number in order of 10 to the power of something we simply find the decimal place and count the number of '0' after the decimal place.

For example: 0.00044001 mm in 10 to the power of something will be

Here 3 zeros ( 0 ) and one '4' after the decimal place so, we multiply and divide the given number by 10 ⁴.

now, ( 0.00044001 x 10 ⁴) / 10 ⁴

such that decimal shift its position by 4,

now, the number becomes 4.44001 / 10 ⁴

then, the answer will be 4.44001 x 10⁻⁴

We have given the diameter of an atom of gold is  0.000000144 mm

such that decimal shifts its position by 7 after getting multiplied by 10⁷.

now, the number becomes ( 1.44 ) / 10⁷

then, the answer will be 1.44 x 10⁻⁷.

Step-by-step explanation:

The solution sets for the inequality 10+y<10-3y and -6≥10-8x are y>-2.5 and x≤0.75, respectively.

Inequality is a mathematical concept used to compare two expressions and determine whether one is larger or smaller than the other. It is represented by symbols such as <, >, ≤, and ≥.

To find the solution set of 10+y<10-3y, we must first isolate the variable y on one side of the equation.

To do this, we need to subtract 10 from both sides of the equation, leaving us with y<-10-3y.

We can then divide both sides by -4 to get

=> y>-2.5.

Thus, the solution set of 10+y<10-3y is y>-2.5.

To find the solution set of -6≥10-8x, we must first isolate the variable x on one side of the equation.

To do this, we need to subtract 10 from both sides of the equation, leaving us with

=> -6≥-8x.

We can then divide both sides by -8 to get

=> x≤0.75.

Thus, the solution set of -6≥10-8x is x≤0.75.
