Investigating Hollywood Movies
In the following exercise, we use data from HollywoodMovies. The dataset includes information on all movies to come out of Hollywood between 2007 and 2013. Do Audience Ratings Differ Based on the Genre of the Movie
The dataset Hollywood Movies includes a quantitative variable on the AudienceScore of the movie as well as a categorical variable classifying each movie by its Genre. The computer output below gives summary statistics for audience ratings based on genre for movies made in 2011, using four of the possible genres.
Variable Genre N Mean StDev Minimum Q1 Median Q3 Maximum
AudienceScore Action 32 58.63 18.39 32.00 44.50 51.00 78.00 93.00
Comedy 27 59.11 15.68 31.00 48.00 58.00 71.00 93.00
Drama 21 72.10 14.55 46.00 59.00 72.00 84.50 91.00
Horror 17 48.65 15.88 25.00 34.00 52.00 60.50 78.00
A) Which genre has the highest mean audience score?
B) Calculate the difference in mean score between comedies and horror movies, and give notation with your answer, using Ic for the mean comedy score and Iy for the mean horror score.
C) In which genre is the lowest score, and what is that score? In which genre is the highest score, and what is that score?
Answer:
a. Genre with highest mean is drama. Mean is 72.10
B. 10.46 is difference between means of comedy and horror
C. Horror has the lowest minimum value at 25.00
Action and comedy both have the highest maximum value at 93.00
Step-by-step explanation:
First create a table with the data provided like I did in the attachment. It would give a clearer picture of what your answers should be.
1. Which genre has the highest mean score?
From the table, we have the means as:
Action = 58.63
Comedy = 59.11
Drama = 72.10
Horror = 48.65
The genre with the highest score is drama at 72.10
2. Difference in mean score between comedy and horror
Mean of comedy = lc = 59.11
Mean of horror = ly = 48.65
Difference = lc-ly
= 59.11 - 48.65
= 10.46
3. The genre with lowest score is the genre with the lowest minimum value. This genre is horror and the lowest minimum is 25.00
The genre with highest minimum value is that whose maximum value is the highest out of all the genres. Both action and comedy have the highest maximum value at 93.00
If it is completely impossible to put a contract in writing, which of the following would be the best substitute?
a. having a friend witness the verbal agreement
a video or audio recording of the verbal agreement
the words "I promise" spoken in a verbal recitation of the contract
d. a firm hand-shake between all those involved in the contract
C.
Please select the best answer from the choices provided
Answer:
B
Step-by-step explanation:
Because the the contract will be in verbal form. no matter if it is videotaped or recorded or both a "videoed verbal contract" not just written. so like paper thst is notarized or not this is still the same bc the the same rules apply the contract is still valid. the rest of the options are more like what they call gentlemens agreements which would be the handshake type of thing. and no matter what any agreement someone has to witness the transaction or contract. so definitely the answer is B
A bike accelerates at 10 m/s2 when a force of 50N is applied. What is the mass of the bike? Group of answer choices
Answer: 5kg
Step-by-step explanation:
The mass of the bike if it accelerates at 10 m/s2 when a force of 50N is applied is 5kg
According to Newton's second law of motion,
Force = mass * acceleration
F = ma
Given the folliowing parameters:
Force = 50N
acceleration = 10m/s²
Get the mass:
mass = F/a
mass = 50/10
mass = 5kg
Hence the mass of the bike if it accelerates at 10 m/s2 when a force of 50N is applied is 5kg.

On which number line do the points represent negative seven and one over two and +1?
i says did u guys know pls helpme!!!!!!!!!!!
Answer:
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

Kelly pays 15% more each month in rent than Cici, and together they pay $1021.25 per month. How much does Cici pay per
month?
Answer:
$475
Step-by-step explanation:
Let the amount paid by Cici per month to be -------- $ x
Kelly pays 15 % more , this will be -------115/100 * x =$ 1.15x
The equation for the sum is :
$x + $ 1.15x = $1021.25
2.15 x = 1021.25
x = 1021.25 / 2.15
x = $475

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 20 5
Answer:
a) aₙ = 12 + (n - 1)*(-2)
b) aₙ = 25 + (n - 1)*(-5)
Step-by-step explanation:
These are arithmetic sequeces.
Usually, the n-th term of an arithmetic sequence can be written as
aₙ = aₙ₋₁ + d
or
aₙ = a₁ + (n - 1)*d
where d is the difference between any two consecutive terms.
a) we have the sequence:
12 10 8 6 4
First, we can take the difference between any two consecutive terms to find the value of d (we should check with different pairs, and see if the value of d is always the same):
d = 10 - 12 = -2
d = 8 - 10 = -2
etc.
And the term a₁ is the first term of the sequence, in this case is 12.
Then the n-th term of this sequence can be written as:
aₙ = 12 + (n - 1)*(-2)
b) 25 20 15 20 5
Same as before, first we find the value of d:
d = 20 - 25 = -5
d = 15 - 20 = -5
etc...
We can see that d is equal to -5
and in this case, the first term is 25, then a₁ = 25
Then the n-th term is:
aₙ = 25 + (n - 1)*(-5)

Step-by-step explanation:
Hence end behavior of function is positive non decreasing.
What is Function?A function is a relationship between a set of inputs and a set of allowable outputs in mathematics. The feature of functions is that each input corresponds to exactly one output. For example, in the function f(x)=[tex]x^{2}[/tex], any x input will result in only one output.
How to solve?Given function [tex]f(x)=\frac{5}{4} x^{2}[/tex]
as the function is square of x hence we can clearly see function is positive

The rectangle below has an area of 30k3 + 6k2.
The width of the rectangle is equal to the greatest common monomial factor of 30k3 and 6k2.
What is the length and width of the rectangle?
Answer:
Width = 6k²
Length = 5k+1
Step-by-step explanation:
Given the area of a rectangle expressed as
A = 30k³ + 6k²
Get the greatest common factor
30k³ = (2 * 3 * k²) * k * 5
6k² = (2 * 3 * k²)
The common factor is the value in bracket i.e 2 * 3 * k² = 6k²
Width of the rectangle = 6k²
Get the length
A = LW
L = A/W
L = 30k³ + 6k²/6k²
L = 6k²(5k+1)/6k²
L = 5k + 1
Hence the length L = 5k+1

A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. If the after-tax total was $1,413.10, and the tax rate in the area is 8.7%, what was the pre-tax subtotal?
Answer:
The pre-tax amount was $1300.
Step-by-step explanation:
Given that:
After-tax total = $1413.10
Tax rate in the area = 8.7%
The pre-tax price would be 100% and this tax rate is an addition.
Total percent = (100+8.7)% = 108.7%
Let,
x be the pre-tax amount.
108.7% of x = 1413.10
[tex]\frac{108.7}{100}x=1413.10\\1.087x = 1413.10[/tex]
Dividing both sides by 1.087
[tex]\frac{1.087x}{1.087}=\frac{1413.10}{1.087}\\x= 1300[/tex]
Hence,
The pre-tax amount was $1300.
