Answer:

The sum of the squared residuals

Step-by-step explanation:

If you sum the residuals, you would get 0

if you sum of the absolute values of the residuals you wouldn't be doing "least-squares regression"

The influence of outliers D The slope is another metric that has nothing to do in creating the regression line

Translate (3, – 4) down 3 units.<br> Then reflect the result over the y-axis.
Greeley [361]

Answer:

Step-by-step explanation:

Best advice: make a sketch (which I can't do here).

When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).

Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).

Arisa [49]

Answer:

5 / 6

Step-by-step explanation:

The green numbers: 1, 2, 5

The even numbers: 2, 4, 6

Since 2 is an overlap, we'll only count it once.

Total outcomes: 6

Successful outcomes: 5

Probability: 5 / 6

Given the right triangle MLK and PLN below ; PL=15, KN=4 and cos(L)= (4/5). Find the length of KM
icang [17]
We can answer the question above by using the trigonometric functions and the concept of similar triangles. 
Given that cos (L) is 4/5. The length of sides PN and NL can be solved. Please see solution below.
                            4/5 = NL / 15   ;    NL = 12
Solving for PN,
                                 PN² + 12² = 15²
The value of PN is 9.
Then, using the concept of similar triangles,
                                KN/(KN + NL) = PN/ KM
Substituting the known values,
                                 4/(4 + 12) = 9 / KM
The value of KM is 36.

The rule at Anna's house is that if she eats all of her vegetables and does all of her chores each day, she earns 2 hours of int
never [62]

Answer:

She has 6 hours left.

Step-by-step explanation:

She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables.  Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved.   So 8 + 3 = 12 - 6 = 6

I need help to find the coordinates
77julia77 [94]
We can solve by using the substitution method
y=-5/3x+3
y=1/3x-3
They are equal to each other because they are both equal to y
-5/3x+3=1/3x-3
Subtract both sides by 1/3 and subtract 3 from both sides

-5/3x-1/3x=-3-3
-2x=-6

Divide both sides by -2
x=3

Plug in x into one of the equation to solve for y
y=1/3(3)-3
y=1-3
y=-2

(3,-2)
