Answer:
I think its 520.68 but im not 100% sure
Differences:
point slope form of line:
(a) equation is
where m is slope and (x1,y1) is a point
(b)This equation of line can be determined when two points are given
(x1, y1) and (x2,y2)
slope intercept form of line:
(a) equation is
where m is a slope
b is y-intercept
(b)This equation of line can be determined when y-intercept and slope are given
Similarilties:
(a) both are equation of straight line
(b) slope is always constant in both
The fractions, numbers, and decimals shown are all slopes.
If the given number is equal to the other, (i.e. slope 7 & slope 7 are equal) then they are
parallel.If the slopes are simply of different values (i.e. slope 5 & slope 6 are intersecting, but should be written as neither.) then they are
neither.If the product of the slopes is -1 ( i.e.
& 2 have a product of -1, so they are perpendicular.) then they are
perpendicular.Now, to the questions.
34. Their product is 1, so they are
neither.35. These are equal, so they are
parallel.36.Their product is -1, so they are <span>
perpendicular.</span>37.Their product is -1, so they are <span>
perpendicular.</span>
Hopefully you understand this better. I'll leave it up to you to answer questions 38-51 ;) If you need help, feel free to message me!
Answer:
<h3>The purpose of a single linear regression is <u>
To predict a dependent variable from data from multiple independent variables</u></h3>
Step-by-step explanation:
The purpose of a simple linear regression is same as a correlation in that the purpose is to measure a linear relationship between two variables to the end.
In that particular case , its purpose is to "predict" the data from a dependent variable to the data from atleast one independent variable.
