Drag the correct graph to the box under the equation it corresponds to.<br><br> HELP YOU GUYS

ra1l [238]

Answer:

<h2>See below</h2>

Step-by-step explanation:

I can't drag and drop the graphs, but I can graph the equations shown. Then, all you will have to do is match the graphs shown the the graph that I will provide.

<h3>EQUATION 1: y = x² - 2</h3>

Graph Properties:

Opens up

Vertex is 0, -2

Axis of symmetry is x = 0

Graph photo shown in file called equation 1 graph

<h3>EQUATION 2: y = 2x²</h3>

Graph Properties:

Opens up

Vertex is 0, 0

Axis of symmetry is x = 0

Graph photo shown in file called equation 2 graph

<h3>EQUATION 3: y = (x - 2)²</h3>

Graph Properties:

Opens up

Vertex is 2, 0

Axis of symmetry is x = 2

natulia [17]

Answer:

1. Placebos are used to randomly assign participants to treatment or control ?

False.

2. Using a random chance procedure to assign subjects to treatment or control reduces bias ?

True.

3. A well-designed placebo allows an experiment to be conducted blind. ?

False.

4. In an observational study, the investigators assign the subjects to treatment or control. ?

False.

5. In a blind experiment, the subjects do not know whether they are in the treatment group or control group. ?

True.

6. Placebos are used so that even the people who do not receive a treatment can benefit from the study. ?

True.

7. A placebo is used in all controlled experiments. ?

True.

8. Controlled experiments can be randomized or nonrandomized.

True.

Step-by-step explanation:

To enable the results from the control group to be compared to the results of a treatment group, placebos are administered to the control group while the treatment or independent group receives the real treatment. Randomization is the process for assigning participants to treatment or control groups, not placebos. The reason for using a random chance procedure to assign subjects to treatment or control groups is to reduce bias.

Hurry for Brainlist =Accurate Answer

cluponka [151]

Step-by-step explanation:

the second line has to be parallel (but not identical), so that the 2 lines do not cross each other, do not have any point in common.

that means it must have the same slope but a different y-intercept.

the line in the graph goes through the origin (0, 0), which makes the y-intercept = 0 (the y value when x = 0).

and we see that the points with integer coordinates seem to be e.g. (3, -2).

so, for the slope (y difference / x difference between 2 points) we use this point and the origin.

x changes by +3 (from 0 to 3).

y changes by -2 (from 0 to -2).

so, the slope is -2/3. and it is always the factor of x.

let's look at the answer options :

2x + 3y = 0

3y = -2x

y = (-2/3)x

this is the identical line, so it is wrong !

2x + 3y = 6

3y = -2x + 6

y = (-2/3)x + 2

the same slope and different y-intercept.

this is the correct solution !

2x - 3y = 9

-3y = -2x + 9

y = (2/3)x - 3

wrong slope. so it is wrong !

y = 3x + 2

wrong slope. so it is wrong !
