The tables below represent the profits earned by a merchandiser from four new consignments of t-shirts. Each consignment contained t-shirts of five different sizes. If we were to plot each of the t-shirt sizes and the profit earned on each new size, we would get a different graph for each consignment. Almost all the graphs showed some association between the two variables, except one consignment, which showed no association. Which of the following consignments shows no association?
In graph 2, the dots are scattered and also no association.
What is an association?
An association (relationship) between two numerical variables can be described by its form, direction, strength, and outliers. A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables.
For the given situation,
There are four new consignments of t-shirts.
Each consignment contained t-shirts of five different sizes.
Graph is plotted as shown below between each of the t-shirt sizes and the profit earned on each new size.
If one variable increases as the other variable increases, there is said to be a positive association.
Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.
No association means that there is no line and all the dots are scattered.
From the graph shown, in graph 2 the dots are scattered. Thus no association.
Hence we can conclude that in graph 2, the dots are scattered and also no association.

Starting at home, Jessica traveled uphill to the toy store for 12 minutes at just 10 mph. She then traveled back home along the same path downhill at a speed of 30 mph. What is her average speed for the entire trip from home to the toy store and back?
Answer: 15 mph
Step-by-step explanation:
Given: Time taken to travel uphill to the toy store= 12 minutes[tex]=\frac{12}{60}=0.2\ hour[/tex]
Let d be the distance(in miles) between the home and toy store.
Also, [tex]Speed=\frac{Distance}{Time}[/tex]
[tex]\\\Rightarrow10=\frac{d}{0.2}\\\Rightarrow\ d=0.2\times10=2[/tex]
Thus, distance from home to toy store= 2 miles
When she turn back, to home distance remains same.
The time taken by her to come back at 30 mph speed=
[tex]Time=\frac{Distance}{speed}=\frac{2}{30}=\ hour[/tex]
Now, the average speed =[tex]\frac{\text{Total distance}}{\text{Total time}}[/tex]
[tex]=\frac{2+2}{0.2+\frac{2}{30}}\\=\frac{4}{\frac{6+2}{30}}\\=\frac{4\times30}{8}=\frac{120}{8}=15\ mph[/tex]

the thickness of a deep dish pizza is approximately 2 x 10^-1 feet. the thickness of a thin crust pizza is approximately 5 x 10^-2 feet. how many times smaller is the thickness of a thin crust pizza compared to the thickness of a deep dish pizza?
A. 0.25
B.0.4
C4
D25
The thickness of a thin crust pizza is 4 times smaller than the thickness of a deep dish pizza.
The question asks us to compare the thickness of a deep dish pizza to that of a thin crust pizza and determine how many times smaller the thin crust is. The deep dish pizza has a thickness of 2 x 10⁻¹ feet and the thin crust pizza has a thickness of 5 x 10⁻² feet. To find how many times smaller the thin crust is, we divide the thickness of the thin crust by the thickness of the deep dish pizza:
(5 x 10⁻² feet) / (2 x 10⁻¹ feet) = 0.25

C) Company B is a better deal if Joseph drives more than 150 miles.
D) Company A is a better deal if Joseph drives less than 150 miles.
E) The price for traveling 150 miles is the same for both compan
Answer:
E.The price for travelling 150 miles is same for both company.
Step-by-step explanation:
We are given that Joseph is going on a trip and he needs to rent a car.
Company A
Charge $0.25 per mile plus $50 rental fee.
Company B charges 40.45 per mile plus $20 rental fee.
A.Total distance=150 miles
Company A
Charges for 150 miles=[tex]150\times 0.25=[/tex]$37.5
Total charges=37.5+50=$87.5
Company B
Charges for 150 miles=[tex]150\times 0.45[/tex]=$67.5
Total charge=20+67.5=$87.5
The price for travelling 150 miles is same for both company.
But if distance greater than 150 miles such 155 miles
Company A
Total charge=[tex]155\times 0.25+50=[/tex]$88.75
Company B
Total charges=[tex]155\times 0.45+20=[/tex]$89.75
Company A is better deal if Joseph more than 150 miles.
If distance 145 miles
Price form company A=[tex]145\times 0.25+50=[/tex]$86.25
Price form company B=[tex]145\times 0.45+20=[/tex]$85.25
Company B is better deal if Joseph travel less than 150 miles.
Hence, option E is true.
Before a renovation, a movie theater had 134 seats. After the renovation, the theater has 196 seats. What is the approximate percentage increase of the number of seats in the theater? If necessary, round to the nearest tenth of a percent.
Answer:46.3%
Step-by-step explanation:
Final answer:
46.3%
Explanation:
To find the approximate percentage increase in the number of seats at the theater, subtract the initial number of seats from the final number, then calculate the percentage increase using this difference.
Percentage Increase:
To calculate the approximate percentage increase in the number of seats at the theater:
Find the difference in the number of seats after and before the renovation: 196 - 134 = 62 seats.Calculate the percentage increase: (62 / 134) * 100% ≈ 46.3%Find the area of the following circle. (Round answer to the nearest whole number.) Circumference = 280 cm. (Hint: Find r from C = 2πr (round r to tenths); then find area). 1) 89 2)560 3)1,989 4)6,246
Answer:
4)6,246
Step-by-step explanation:
First we will find the value of r.
The formula for circumference is C = 2πr:
280 = 2(3.14)r
280 = 6.28r
Divide each side by 6.28:
280/6.28 = 6.28r/6.28
44.6 ≈ r
The formula for the area of a circle is
A = πr²
Using our value for r, we have
A = 3.14(44.6)² = 6245.9624 ≈ 6246
Area of circle is,
⇒ 11493.2 cm²
What is mean by Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
Circumference of circle = 280 cm.
Now, We know that;
Circumference = 2πr
Hence, We get;
⇒2πr = 280
⇒ 2 × 3.14 r = 380
⇒ 6.28 r = 380
⇒ r = 380 / 6.28
⇒ r = 60.5
Hence, Area of circle is,
⇒ πr²
⇒ 3.14 × 60.5²
⇒ 11493.2 cm²

Step-by-step explanation:
If 543 planes leave from JFK airport and each plane has 228 passengers, how many people have flown out of JFK? people;
123,804 people have flown out of JF-K airport based on the assumption of full plane occupancy. Real-world variations and logistical complexities may impact the actual number.
To find the total number of people who have flown out of JF-K, you can multiply the number of planes by the number of passengers per plane.
543 planes * 228 passengers/plane = 123,804 people
Therefore, 123,804 people have flown out of JF-K airport.
It's important to note that this calculation assumes each plane is fully occupied and that there are no variations in passenger counts.
In reality, the number of passengers on each plane may vary, and factors such as seat availability, ticket sales, and other considerations can affect the actual number of people who have flown out of JF-K. Additionally, this calculation does not account for return flights, layovers, or other complexities in air travel logistics.

A scientist wants to measure out 0.62 liters of a liquid, but she can only find a beaker that measures volume in milliliters. How many milliliters should she measure to equal 0.62 liters?
To convert 0.62 liters to milliliters, you multiply 0.62 by 1,000, which equals 620 milliliters. Therefore, the scientist should measure out 620 milliliters of the liquid.
Explanation:When a scientist wants to measure out 0.62 liters of a liquid, but only has a beaker that measures volume in milliliters, she needs to first understand the conversion between liters and milliliters. 1 liter is equal to 1,000 milliliters. So, she would need to convert 0.62 liters to milliliters. She can do this by multiplying 0.62 liters by 1,000. This gives her 620 milliliters. Therefore, if a scientist wants to measure out 0.62 liters of a liquid, but the beaker only measures volume in milliliters, then she should measure out 620 milliliters.
