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.
Answers
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.

A store display shows two red shirts, four blue shirts, and
four shirts with red and white stripes. The display also
shows four pairs of blue jeans, two pairs of white pants, and
four pairs of red shorts. What is the probability of randomly
selecting an item with white or red on it?
0 2/5
03/5
0 3/10
1/5
Answers
Answer:
The probability is 3/5
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 2 + 4 + 4 + 4 + 2 + 4 = 20 itens.
Of those, 2 + 4 + 2 + 4 = 12 itens have white or red.
So
12/20 = 3/5

Step-by-step explanation:
The set is formed by months of year with indexes larger than 0 and lesser than 12.
The year starts at month 1, which is January, and finishes at month 12, which is December.
Since we want lesser than 12, December is not part of the set. So the answer is given by:

A) Write a linear function that relates the amount of gasoline to the traveling distance.
B) How many gallons of gasoline are left after you drive 120 miles?
Answers
Answer:
A) [tex]y=-\frac{1}{20}x+20[/tex]
B) 14 gallons of gasoline
A linear function that relates the amount of gasoline to the traveling distance is : y = - (1/20)x + 20 and the gallons of gasoline left after you drive 120 miles will be 10 gallons.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is a table shows the amount of gasoline [g] (in gallons) left in your tank after you travel [m] miles.
The given table is -
Miles [m] Gallons [g]
0 20
20 19
40 18
60 17
We can write the linear function as -
y = mx + c
We can write the slope as -
m = {(19 - 20)/(20 - 0)}
m = (- 1/20)
At [x] = 0, then [y] = 20. So, the equation will be -
y = (-1/20)x + 20
y = - (1/20)x + 20
At [x] = 120 miles -
y(120) = (-1/20 x 200) + 20
y(120) = - 10 + 20
y(120) = 10 gallons
Therefore, a linear function that relates the amount of gasoline to the traveling distance is - y = - (1/20)x + 20 and the gallons of gasoline left after you drive 120 miles will be 10 gallons.

Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15

-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.

Solve for g.
what is g equal to?
Answers
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]

The question is asking you to find how many real roots there are. You use factoring to find the roots of this polynomial function. The steps for factoring are to factor out the GCF, factor, and solve for the x’s.
You then determine negative and positive roots.
