<u>I'll assume you need to find the equation of the line that passes through those points.</u>
Answer:
Step-by-step explanation:
<u>Equation of a Line:</u>
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
The given points are (-4,2) and (12,6), thus:
Operating:
Simplifying, the equation in point-slope form is:
Answer:
d) Squared differences between actual and predicted Y values.
Step-by-step explanation:
Regression is called "least squares" regression line. The line takes the form = a + b*X where a and b are both constants. Value of Y and X is specific value of independent variable.Such formula could be used to generate values of given value X.
For example,
suppose a = 10 and b = 7. If X is 10, then predicted value for Y of 45 (from 10 + 5*7). It turns out that with any two variables X and Y. In other words, there exists one formula that will produce the best, or most accurate predictions for Y given X. Any other equation would not fit as well and would predict Y with more error. That equation is called the least squares regression equation.
It minimize the squared difference between actual and predicted value.

Answer:
$51.30
Step-by-step explanation:
76 decrease 25% =
76 × (1 - 25%) = 76 × (1 - 0.25) = 57
57 decrease 10% =
57 × (1 - 10%) = 57 × (1 - 0.1) = 51.3
Answer:
Concept: Mathematical Derivation
- We are given x^2 +6x+2x+12
- Hence we simplify: x^2 + 8x +12
- Now we factor: (x+2)(x+6)
- By mathematical logic we now proved that the roots are x=-2 and x=-6
- Give brainlist and rate positively
