por que si por 25 son 4 en 75 son 12
Answer:
-x^5 - 7x^4 + x^2 + (1/8)x - 9
Step-by-step explanation:
Rewrite the given -9+1/8x-7x^4+x^2-x^5 in descending order of the variable x:
-9+1/8x
-x^5 - 7x^4 + x^2 + (1/8)x - 9
Answer:
Correct option:
Is a measure of the amount of variability in one variable that is shared by the other.
Step-by-step explanation:
<em>R</em>-squared is a statistical quantity that measures, just how near the values are to the fitted regression line. It is also known as the coefficient of determination.
The coefficient of determination <em>R</em>² specifies the percentage of the variance in the dependent-variable (<em>Y</em>) that is forecasted or explained by linear regression and the forecaster variable (<em>X</em>, also recognized as the independent variable).
The coefficient of determination <em>R</em>² can be computed by the formula,
Or,
Here,
MSS = model/regression sum of squares
TSS = total sum of squares
Thus, the correct option is:
" Is a measure of the amount of variability in one variable that is shared by the other."
Answer:
7) A
8) 1/2
9) 5000
Step-by-step explanation:
7)
(0, 0), (4, -10)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (-10 - 0)/(4 - 0) = -10/4 = -5/2
Equation: y = -5/2 x
Answer: A
8)
(0, 0), (2, 1)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (1 - 0)/(2 - 0) = 1/2
Equation: y = 1/2 x
Answer: 1/2
9)
The value of the house increases $5000 per year, so we multiply the number of years, x, by 5000 to find the increase after x years.
Equation: y = 5000x
Answer: 5000
