In order to test for the significance of a regression model involving 4 independent variables and 47 observations, the numerator

Karolina [17]

Answer:

c. 4 and 42

Step-by-step explanation:

Given

$p = 4$ -- independent variables

$n = 47$ ---- observations

Required

The numerator and denominator degrees of freedom

The denominator degrees of freedom is:

$df =n - p - 1$

$df =47 - 4 - 1$

$df =42$

For the numerator, we have:

$df = p$

$df = 4$

How many tenths are there in 4/5

il63 [147K]

What we have to solve is:

$\frac{4}{5} = \frac{x}{10}$

we should multiply both sides by10, to get the "x" by itself:

$\frac{4*10}{5} = \frac{x}$

$\frac{4*2}{1} = \frac{x}$

$8 = \frac{x}$
so there are 8 tenths in this number!

Write the equation of the line that passes through each pair of points in slope-intercept form. This is worth 3 points. You have

LekaFEV [45]

(0,5)(3,-1)
slope = (-1 - 5) / (3 - 0) = -6/3 = -2

y = mx + b
slope(m) = -2
(use either of ur points...(0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = -2(0) + b
5 = b

so ur line is : y = -2x + 5

If 4x+y=h, then x is equal to

lianna [129]

4x + y = h

Rearrange the problem so your equation equals x, not h
y - h = -4x

Divide both sides by -4
-4y - 4h = x
