The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression 2.75+0.10x, where x is the number of years since 1980.
Which part of the expression corresponds to the cost of movie tickets in 1980?
Answers
Answer:
2.75
Step-by-step explanation:
0.10 represents the rate at which prices have increased since 1980..
2.75 represents the price in 1980
This can be confirmed by inputting 0 as the value of x.
2.75+0.10(0) = 2.75

A bag has 5 yellow marbles, 3 red marbles and 2 blue marbles. Quinn randomly picks a marble from the bag and returns it before another is picked. How many times would Quinn expect to pick a blue marble if he picks a marble 200 times?
Answers
Answer:
Quinn can expect to pick blue 40 times
Step-by-step explanation:
the probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
Answer:40 blue marbles
Step-by-step explanation:
First find the probability of a blue marble
P (blue) = number of blue marbles / total marbles
= 2 blue/ ( 5+3+2) total
= 2/10
=1/5
We can use this since we return the marble to the bag each time
We multiply this by 200 for the number of times it is picked
200 * 1/5 = 40
We should expect to pick 40 blue marbles

The London School of Economics and the Harvard Business School have conducted studies of how chief executive officers (CEOs) spend their time. These studies have found that CEOs spend many hours per week in meetings that include conference calls, business meals, and public events. Suppose that the data below show the time spent per week in meetings (hours) for a sample of 25 CEOs.
14 15 18 23 15
19 20 13 15 23
23 21 15 20 21
16 15 18 18 19
19 22 23 21 12
a. What is the least amount of time spent per week on meetings? The highest?
b. Use a class width of two hours to prepare a frequency distribution, a relative frequency distribution, for the data.
Answers
Answer:
(a) The least amount of time spent per week on meetings is, 12 hours.
The highest amount of time spent per week on meetings is, 23 hours.
(b) Shown below.
Step-by-step explanation:
(a)
Arrange the data in ascending order.
S = {12 , 13 , 14 , 15 , 15 , 15 , 15 , 15 , 16 , 18 , 18 , 18 , 19 , 19 , 19 , 20 , 20 , 21 , 21 , 21 , 22 , 23 , 23 , 23 , 23}
The least amount of time spent per week on meetings is, 12 hours.
The highest amount of time spent per week on meetings is, 23 hours.
(b)
The frequency distribution table with the relative frequency distribution is as follows:
Class Interval Frequency Relative Frequency
12 - 14 3 0.12
15 - 17 6 0.24
18 - 20 8 0.32
21 - 23 8 0.32

n1 = 900 n2 = 400
Number making claims = 135 Number making claims = 24
Required:
a. Use a level of significance α = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
b. Provide a 95% confidence interval for the difference between the proportions for the two populations.
Answers
Answer:
Step-by-step explanation:
Given the following :
Single policy holders (n1) = 900
Number making claims (x1) = 135
Married Policy holders (n2) = 400
Number making claims (x2) = 24
α = 0.05
a. Use a level of significance α = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
Null: p1 - p2 = 0
Alternative : p1 - p2 ≠ 0
p = (n1p1 + n2p2) / n1 + n2 ;
p1 = x1/n1 = 135 / 900 = 0.15
p2 = x2/n2 = 24 / 400 = 0.06
p = (900*0.15 + 400*0.06) / (900 + 400)
p = 0.1223076
Test statistic (z):
(p1 - p2) / √p(1-p)(1/n1 + 1/n2)
(0.15 - 0.06) / √0.12231(1-0.12231)(1/900 + 1/400)
= 4.5710979
Decision:
Reject Null if P < α
Obtaining p value from z score using calculator :
P value = 0.0001
0.0001 < 0.05
Hence,
Reject Null

The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd, find its area.
Answers
Answer:
all the sides multiplies should equal 48
Step-by-step explanation:
sorry I don't know
The rectangle will have a 432 yd² area.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd
Let "l " be the length of the rectangle
thus, the width of the rectangle = l/3
Since the Perimeter of the rectangle = 48 yd
From the general formula of the Perimeter of the rectangle:
perimeter = 2*(length + width)
In our case
Perimeter = 2*( l + l/3)
Perimeter = 2*(2l/3)
Perimeter = 4L/3
Thus,
4L/3 = 48
L = 36 yd
So width = 36 /3 = 12
Since the area of the rectangle = length * width
Area = 12 * 36
Area = 432
therefore, the area of the rectangle will be 432 yd².

decrease of 65% is the same as multiplying by what
percent?
Answers
Answer:
35%
Step-by-step explanation:
A decrease of 65% would be the same as multiplying the value by 35%.
100% - 65% = 35%
Let's use an example.
You have $150 dollars in stock and it decreases by 65%
150 - (.65*150) =
150 - 97.5 = $52.50
Now let's just multiply $150 by .35 (which is 35%)
150 * .35 = $52.50
It's the same!

A chef needs 60 oz of hot pepper sauce.
Which container size represents the better buy?
What will be the total cost of those containers?
Answers
Answer:
30-oz is a better buy
Total cost: $40.80
Step-by-step explanation:
The container with a lesser price per oz will be the better buy.
Let's calculate how much each container will give us per oz:
2-oz container = $1.99/2 = $0.995 per oz
5-oz container = $3.95/5 = $0.79 per oz
12-oz container = $8.76/12 = $0.73 per oz
30-oz container = $20.40 = $0.68 per oz
The 30-oz container is cheaper and would be a better buy.
In total the chef would buy 60-oz of hot pepper sauce for = 60-oz*$0.68 = $40.80
