Answer:
13
Step-by-step explanation:
To find the distance, d, between two points on the Cartesian plane use the distance formula.
The points are (3, -4) and (8, 8), so you can use:
x1 = 3
y1 = -4
x2 = 8
y2 = 8
Now plug in all values above in the formula and evaluate it.
![d = \sqrt{(8 - 3)^2 + [8 - (-4)]^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%288%20-%203%29%5E2%20%2B%20%5B8%20-%20%28-4%29%5D%5E2%7D%20)
Answer:
Options A & C are False while Options B & D are true.
Step-by-step explanation:
The definition of least squares regression line is given as;
The Least Squares Regression Line is a line that normally causes the vertical distance from the data points to the regression line to be as small as possible.
The term “least squares” is derived from the fact that the best line of fit is one that minimizes the the sum of squares of the errors which is also called the variance.
From this definition above, we can see that options A and C are false while option B is the perfect definition for the least line of squares.
Now, the point (x-bar,y-bar ) is known as the mean.
However, every least squares must pass through the middle point of the given data. The mean is the middle point of data in regression analysis. Thus, we can infer that the least-squares regression line always passes through the mean which is point (x-bar,y-bar ). Thus, option D is true.
A fraction is just the easier, cleaner way of writing a division problem
the numerator is the number you are dividing
the denominator is the number you are dividing with
EX- 2 divided by 3 as a fraction is
2/3
16*7.96=127.36
