Does the type of program people watch influence how much they eat? A total of 94 college students were randomly assigned to one of three treatments: watching 20 minutes of a Hollywood action movie (The Island), watching the same 20-minute excerpt of the movie with no sound, and watching 20 minutes of an interview program. While watching, participants were given snacks (M&M’S®, cookies, carrots, and grapes) and allowed to eat as much as they wanted. Subjects who watched the highly stimulating excerpt from The Island ate 65% more calories than subjects who watched the interview show. Participants who watched the silent version of The Island ate 46% more calories than those who watched the interview show.36 Identify the explanatory and response variables in this study. Then determine if it is an experiment or an observational study. Explain your reasoning.
Answer:
The explanatory variable is the type of program the people watched. The response variable is the number of calories consumed. This was an experiment.

Answer:
(-2,-1)
Step-by-step explanation:
Reflecting a point over the y-axis means to have the point either to the right or left of the originial point.
Given that the endpoints of a diameter are (7,-3) and (-1,7), determine the equation of the circle.
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^r
H and k are the x and y coordinates of the center of the circle and r is the radius.
You are given the diameter coordinates so find the halfway point for the center then calculate the radius
Midpoint = (x1 +x2)/2, (y1 + y2)/2
Midpoint = (7 + -1)/2, (-3 +7)/2
Midpoint = 6/2, 4/2
Midpoint = 3,2
So h = 3 and k = 2
Now find radius by finding the distance between the center point and an end point.
Distance = sqrt(41)
Equation of the circle:
(X-3)^2 + (y-2)^2 = 41
Answer:
The equation of the circle is written as:
(x-h)²+(y-k)²=r²
'h' and 'k' are the x and y coordinates of the center of the circle and 'r' is the radius.
You are given that the diameter coordinates, so find the halfway point for the center then calculate the radius
[tex]Midpoint = ( \frac{x_1 + x_2 }{2}, \frac{y_1 + y_2}{2} ) \\ = ( \frac{7 + ( - 1)}{2} , \frac{ (- 3 )+ 7}{2} ) \\ = ( \frac{6}{2} ,\frac{4}{2} ) = (3,2)[/tex]
So, h=3 and k=2
Now find the radius by finding the distance between the center point and the end point.
Distance=√{(7-3)²+(-3-2)²}=√{(4)²+(-5)²} =√{16+25}=√41
Equation of the circle:
(x-3)²+(y-2)²=41 ✓
Solve for g.
what is g equal to?
Answer:
[tex]\displaystyle g=\frac{4\pi^2l}{T^2}[/tex]
Step-by-step explanation:
Equation Solving
Given the equation
[tex]\displaystyle l=\frac{gT^2}{4\pi^2}[/tex]
It's required to solve it for g. Let's swap sides of the equation:
[tex]\displaystyle \frac{gT^2}{4\pi^2}=l[/tex]
Multiply by [tex]4\pi^2[/tex] to remove the denominator:
[tex]\displaystyle gT^2=4\pi^2l[/tex]
Divide by [tex]T^2[/tex]
[tex]\boxed{\displaystyle g=\frac{4\pi^2l}{T^2}}[/tex]

Milos is trying to prove that the sum of any two rational numbers is a rational number. His first steps are shownWhich is the best method Milos could use to continue?
Answer:
Answer is the first one
Step-by-step explanation:
Method A will be best to prove the condition, "the sum of any two rational numbers is a rational number."
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
It is given that, Milos is trying to prove that the sum of any two rational numbers is a rational number
Two rational numbers added together make rational number.As a result, adding two rationals is equivalent to adding two of these fractions, which will produce a new fraction with the same form since integers are closed under addition and multiplication. As a result, multiplying two rational numbers results in another rational number.
Thus method A will be best to prove the condition, "the sum of any two rational numbers is a rational number."
