Identify proportional relationships from tables

To test whether or not the population regression function is linear rather than a polynomial of order r,

QveST [7]

Answer:

To test whether or not the population regression function is linear rather than a polynomial of order r, use the test of (minus1) restrictions using the F Minus Statistic.

Therefore, option D is the correct answer choice.

Step-by-step explanation:

The test of (r-1) restrictions using the F statistic is the most effective way to test whether or not the population regression function is linear rather than a polynomial of order r.

Therefore, 'use the test of (minus1) restrictions using the F Minus Statistic', option D is the correct answer choice.

Keep getting this wrong

Minchanka [31]

Remember that the y-intercept is where the function has a value of $x = 0$ and the x-intercept is where the function has a value of $y = 0$ . Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.

x-intercept

Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for $x$ .

$0 = -2x - 3$

Set up

$3 = -2x$

Add 3 to both sides

$x = - \dfrac{3}{2}$

Divide both sides by -2

The x-value of the x-intercept is $-\frac{3}{2}$ and the y-value is 0, meaning that the x-intercept has coordinates $\boxed{(-\frac{3}{2}, 0)}$ .

y-intercept

Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for $y$ :

$y = -2(0) - 3$

Set up

$y = -3$

Multiply and simplify

The y-value of the y-intercept is -3, meaning that the y-intercept of the function is $\boxed{(0, -3)}$ .

Graph the system of equations. {8x+8y=642x−2y=−4

klemol [59]

The graph is attached.

Explanation:
We can use the x- and y-intercepts to graph. The x-intercept of the first equation is 8, and the y-intercept is 8. The x-intercept of the second equation is -2, and the y-intercept is 2.

x-intercepts are where the data crosses the x-axis. At every one of these points, the y-coordinate will be 0; therefore we can substitute 0 for y and solve to get the value of the x-intercept.

For the first equation, we would have
8x+8(0)=64
8x=64.

Divide both sides by 8:
8x/8 = 64/8
x=8.

For the second equation,
2x-2(0)=-4
2x=-4.

Divide both sides by 2:
2x/2 = -4/2
x=-2.

y-intercepts are where the data crosses the y-axis. At every one of these points, the x-coordinate will be 0; therefore we can substitute 0 for x and solve to get the value of the y-intercept.

For the first equation,
8(0)+8y=64
8y=64.

Divide both sides by 8:
8y/8 = 64/8
y=8.

For the second equation,
2(0)-2y=-4
-2y=-4.

Divide both sides by -2:
-2y/-2 = -4/-2
y=2.

Plot these points for both equations and connect them to draw the line.
