A college professor hypothesizes that readers will comprehend more when reading a graphic novel than when reading text with no illustrations. To conduct an experiment, the professor will assign some students to the control group with a reading assignment in paragraph form and other students to the treatment group with a reading assignment in graphic novel form. Afterwards, all the students will take a quiz about the reading to measure comprehension. To assign the groups, the professor will split the students into five groups according to their current grade in the class: A, B, C, D, or F. Within each group, half of the students will be assigned to the treatment group with the graphic novel, and the rest will be assigned to the control group with the paragraph.

The characteristics of the treatment and control groups

should be roughly equivalent because the students are from a randomly chosen class.
might not be roughly equivalent because the students could have vastly different views about graphic novels.
should be roughly equivalent because both groups have a mixture of students with different current grades.
might not be roughly equivalent because the students were not labeled and randomly chosen for each group.

Answers

Answer:

should be roughly equivalent because both groups have a mixture of students with different current grades.

Step-by-step explanation:

The characteristics of the treatment and control groups should be roughly equivalent because both groups have a mixture of students with different current grades.

What is control groups?

It is comprise of the participants where it does not collect the experimental treatment. At the time when the experiment is conducted, the people should be allocated to the group. Also, it should resemble the participants.

Hence, The characteristics of the treatment and control groups should be roughly equivalent because both groups have a mixture of students with different current grades.

Answers

Answer:

3.) Choice B

4.) Choice A

Step-by-step explanation:

Question #3:

You can find the equation by doing the y divided by the x and you'll get 4 every time so that's why it's Choice B.

Question #4:

A proportional equation is always a straight line that goes through the origin. So the answer is Choice A because it's the only one without a y-intercept because if the equation had a y-intercept it wouldn't go through the origin. For example, Choice B would go through (0,5) and Choice C would go through (0,-1) but we need it to go through (0,0).

Gwen is two years older than her cousin Julie. Aunt Jess is twice as old as uncle Mark. Julie’s age is 26 less than the sum of aunt Jess and uncle Mark’s ages. The twins are 2 years younger than one-third Gwen’s age. Mark celebrated his 8th birthday at the reunion 10 years ago

Answers

If mark celebrated his 8th birthday 10 years ago then mark is 18 years old. Jess is twice as old as mark so Jess is 36 years old. Julie is 26 less than mark and jess combined so Julie is 28 years old. Gwen is two years older than Julie so Gwen is 30 years old. The twins are 2 less than 1/3 of gwen so the twins are 8 years old

Answer:

-12s - 2t

Step-by-step explanation:

First simplify the like terms.

-3s * 4s = -12s

(-12s + 2t)(-t)

Simplify the like terms again.

2t * (-t) = -2t

-12s - 2t.

Or

[tex]\frac{3}{1}[/tex] or 3

Step-by-step explanation:

To find the slope find two coordinates and set up the equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. [tex]\frac{8_{}-2_ }{2-0_ }[/tex] you have to do subtraction first. 8-2 = 6 and 2-0 = 2

Now we have the equation [tex]\frac{6}{2}[/tex]

this can be simplified to  [tex]\frac{3}{1}[/tex]
