1/40,000 = h/10
40,000h = 10
h = 10/40,000
h = 1/4,000
The most common method for fitting a regression line is the method of least-squares. This method calculates the best-fitting line for the observed data by minimizing the sum of the squares of the vertical deviations from each data point to the line (if a point lies on the fitted line exactly, then its vertical deviation is 0). Because the deviations are first squared, then summed, there are no cancellations between positive and negative values.Example<span>The dataset "Televisions, Physicians, and Life Expectancy" contains, among other variables, the number of people per television set and the number of people per physician for 40 countries. Since both variables probably reflect the level of wealth in each country, it is reasonable to assume that there is some positive association between them. After removing 8 countries with missing values from the dataset, the remaining 32 countries have a correlation coefficient of 0.852 for number of people per television set and number of people per physician. The </span>r²<span> value is 0.726 (the square of the correlation coefficient), indicating that 72.6% of the variation in one variable may be explained by the other. </span><span>(Note: see correlation for more detail.)</span><span> Suppose we choose to consider number of people per television set as the explanatory variable, and number of people per physician as the dependent variable. Using the MINITAB "REGRESS" command gives the following results:</span>
<span>The regression equation is People.Phys. = 1019 + 56.2 People.Tel.</span>
The distance between (-5 , -8) and (-1 , -16) is 8.9 units ⇒ 1st answer
Step-by-step explanation:
The distance between points 
and 
is 
To find the distance between two points
- Chose one of the two point to be
- Use the other point to be
- Substitute them in the rule of the distance
∵ The first point is (-5 , -8)
∵ the second point is (-1 , -16)
∴ 
= -5 and 
= -1
∴ 
= -8 and 
= -16
- Substitute these values in the rule of the distance
∵ 
∴ 
∴ 
∴ 
∴ 
∴ d = 8.9 units
The distance between (-5 , -8) and (-1 , -16) is 8.9 units
