Based on the boxplots, which statement below is true? A) The range of both plots is about the same. B) The means of both plots are approximately equal. C) Plot B contains more data points than Plot A. D) The medians are approximately equal.
Answer: A. The range of both plots is about the same.
Step-by-step explanation:
The question asks about boxplots but does not provide the actual boxplots to analyze. Nonetheless, the answer describes what each statement means in relation to boxplots. The true statement would depend on graphical interpretation of the provided boxplots.
Explanation:Without actual boxplots, it is not possible to definitively answer this question. However, I can provide you with a brief description of each of the given options.
The range of both plots is about the same: This implies that the lowest and highest values of both data sets are similar.The means of both plots are approximately equal: This suggests that the average values of both data sets are similar.Plot B contains more data points than Plot A: This isn't usually determinable by a boxplot since boxplots show the spread and distribution of data, not the quantity of data points.The medians are approximately equal: This implies that the mid-values of the data sets are similar.In general, to get a correct answer, study the two boxplots together, comparing their ranges, means, and medians.

What is the difference between the circumference of the outer circle and the circumference of the inner circle? Leave your answer in terms of π.
Diameter is 9m and the outer part of the circle is 2m
Will give brainiest
Final answer:
The difference between the circumferences of the outer and inner circles, given a diameter of 9m for the inner circle and an outer part thickness of 2m, is 4π m.
Explanation:
To find the difference between the circumferences of an outer circle and an inner circle, we first need to determine their respective radii and then apply the circumference formula C = 2πr.
The given diameter of the inner circle is 9m, hence its radius is 9m / 2 = 4.5m. The thickness of the outer part of the circle is 2m, so the radius of the outer circle is 4.5m + 2m = 6.5m.
The circumference of the inner circle is C_inner = 2π(4.5m) = 9π m, and the circumference of the outer circle is C_outer = 2π(6.5m) = 13π m.
The difference between the circumferences is therefore Couter - Cinner = 13π m - 9π m = 4π m.

When looking at the unit circle, what do you notice about the value of sine and the value of the y coordinate?
a the values are the same
C. the values are opposites
b. the absolute values are different
d. none of the above
Answer:
a. the values are the same.
Step-by-step explanation:
The sine = y-coordinate / hypotenuse. The unit circle has hypotenuse = 1, so
the sine = y /1 = y.
Final answer:
The value of the sine of an angle on the unit circle is the same as the y-coordinate of the corresponding point on the circle, as the sine function is defined as the ratio of the opposite side to the hypotenuse in a right triangle.
Explanation:
When looking at the unit circle, we can observe that the value of the sine of an angle is indeed the same as the y-coordinate of the point on the unit circle at that angle. In other words, if we take a point on the unit circle at an angle θ from the positive x-axis, its coordinates can be expressed as (cos(θ), sin(θ)). Therefore, the sine of the angle gives us the y-coordinate of the point on the circle. This relationship is a direct consequence of how the trigonometric functions are defined in the context of a right triangle, where the sine of an angle is the length of the side opposite to the angle (y) divided by the hypotenuse (which is 1 for the unit circle).
The sum of two numbers is 98. One number is 76 less than the other.
Answer:
Step-by-step explanation:
1. n + y = 98
2. n = 76 - t
Answer:
11 and 87
Step-by-step explanation:
Let's create an equation to solve this. (I know that it is just subtraction, but equations are great ways to understand concepts.)
We can represent each number as "n"
In that case, we have:
n + (n - 76) = 98
Grouping n's:
2n - 76 = 98.
Adding 76 to both sides:
2n = 174
Dividing by 2:
87.
Plug-and-chug:
87 + (87 - 76) = 98
Thus, our final answer is that one number is 11, the other 87.
A business has $15,000 to spend on airline tickets to travel to a conference. It wants 27 of its employees to attend. The business wants to buy as many business-class seats as possible. The business-class seats cost $700. The economy-class seats cost $375. Create a system of equations that models how many of each type of ticket the business should purchase.
700x + 375y = 27
x + y = 15,000
x + 375y = 15,000
700x + y = 27
700x + y = 15,000
x + 375y = 27
700x + 375y = 15,000
x + y = 27
Answer:
Here is the correct system of equations:
700x + 375y = 15,000
x + y = 27
The system of equations that models how many of each type of ticket the business should purchase is 700x + 375y = 15,000; x + y = 27. option D
How to write system of equation?
Let
x = the number of business class.
y = the number of economy
x + y = 27 (1)
700x + 375y = 15000 (2)
Multiply (1) by 700
700(x + y) = 700(27)
700x + 700y = 18900 (3)
Subtract (2) from (3)
700x + 375y = 15000 (2)
700x + 700y = 18900 (3)
-325y = -3900
Divide both sides by -325
y = -3900/-325
y = 12
Recall
x + y = 27
x + 12 = 27
x = 27 - 12
x = 15
Therefore, the business should purchase 15 business class and 12 economy class.

It's negative
After 3 years = 2(9) -6(3) -3
= 18 - 18 -3
= -3
It's negative
After 4 years = 2(16) -6(4) -3
= 32 -24-3
= 5
It's positive
After 4 years the profit will change from negative to positive
b) after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.

Step-by-step explanation:
(English question:
Mr. Bartek bought 15 flower seedlings and paid PLN 67.50 for them. Mr. Michał bought 50 cuttings at the same price for one piece.
How much more did Michał pay for seedlings than Mr. Bartek? Choose the right answer from the given ones.
A. 22.50 PLN B. 157.50 PLN C. 202.50 PLN D. 225 PLN)
We can solve this problem using a rule of three:
If Mr. Bartek bought 15 flowers seedlings for 67.5, Mr. Michal that bought 50 flowers seedlings will pay what price (If he pays the same price per unit that Mr. Bartek paid)?
15 seedlings -> PLN 67.5
50 seedlings -> PLN X
15/50 = 67.5/X
X = 50*67.5/15 = 225
The correct option is D: 225 zł

If U = 3 inches, V = 5 inches, W = 8 inches, X = 6 inches, Y = 8 inches, and Z = 4 inches, what is the area of the object?
Answer:
46.5 inches
Step-by-step explanation:
if you plug all the numbers in and then change them into simple shapes, like a square, rectangle, and triangle, you can just add the areas to those shapes and add them together.
The area of the object is: 61.5 Sq.in
What is the Area of the Composite figure?
The formula for area of a rectangle is:
Area = Length * Width
Formula for the Area of a Trapezium is:
Area = ¹/₂ * (sum of parallel sides) * height
Area of composite figure is: (¹/₂ * (W + Y - U) * (V - X - Z)) + [(X - Z) * (Y - U)] + (Y * Z)
Area of composite figure is: (¹/₂ * (8 + 8 - 3) * (5 - (6 - 4)) + [(6 - 4) * (8 - 3)] + (8 * 4)
= 19.5 + 10 + 32
= 61.5 Sq.in
Lin wants to know how many games teenagers in the United States have on their phones.
What is the population for Lin's question?
The population for Lin's question is all teenagers in the United States who use smartphones. Selection bias and the method of surveying can cause data variations, and the sample size must be large enough and representative to obtain accurate findings.
Explanation:The population for Lin's question regarding how many games teenagers in the United States have on their phones is all teenagers in the United States who own and use smartphones. It is implied that Lin is interested in the averages or trends among this specific age group with regard to digital game ownership.
When considering data collection, several factors can cause variations in the results. For instance, adolescents' access to different technologies, social and economic factors, and varying interests can all influence the number of games they have on their phones. Additionally, methods of surveying can affect accuracy, such as if the respondents are primarily contacted by landline or mobile phone, reflecting different demographic characteristics. The trend towards mobile phone usage as opposed to landlines, selection bias, and the changing communication preferences of younger generations all emphasize the need for researchers to employ diverse methods in collecting data to ensure representativeness of the surveyed population. Moreover, the sample size and how well it represents the overall population is critical in obtaining reliable results.
The sufficiency of the sample size depends on the population being studied. If the sample consists solely of students from one school, it may not be representative of the wider population of teenagers in the United States. However, when the population is as large and diverse as school-aged children and young adults across the entire United States, a much larger and varied sample would be needed to appropriately reflect the population and offer meaningful conclusions.

The flying squirrel of eastern Texas can drop a height of 60 feet. A function that approximates this drop is h=-16t^2+60, where h is the height in feet and t is the time in seconds. About how many seconds does it take for the squirrel to drop 60 feet?
Answer:
About 1.94 seconds
Step-by-step explanation:
The quadratic equation gives the height of the squirrel from its starting position, which is 60 feet above ground.
The equation is:
[tex]h=-16t^2+60[/tex]
To find time it takes to "drop" 60 feet, means the ground level, where height is equal to 0.
Or, h = 0
We substitute h = 0 into the equation and solve for t:
[tex]h=-16t^2+60\\0=-16t^2+60\\16t^2=60\\t^2=3.75\\t=\sqrt{3.75}\\t=1.94[/tex]
So, it takes the squirrel about 1.94 seconds to drop 60 feet
It takes the squirrel about [tex]\( \boxd{1.94} \)[/tex] seconds to drop 60 feet.
Step 1
Given the equation [tex]\( h = -16t^2 + 60 \)[/tex] where h is the height in feet and t is the time in seconds.
To find the time it takes for the squirrel to drop 60 feet (reaching the ground), we set [tex]\( h = 0 \)[/tex] and solve for t :
[tex]\[ -16t^2 + 60 = 0 \][/tex]
Add [tex]\( 16t^2 \)[/tex] to both sides:
[tex]\[ 16t^2 = 60 \][/tex]
Step 2
Divide both sides by 16:
[tex]\[ t^2 = \frac{60}{16} \]\[ t^2 = 3.75 \][/tex]
Take the square root of both sides:
[tex]\[ t = \sqrt{3.75} \]\[ t \approx 1.94 \][/tex]
So, it takes the squirrel about [tex]\( \boxd{1.94} \)[/tex] seconds to drop 60 feet.
The table and the graph below each show a different relationship between the same two variables, x and y:
How much more would the value of y be in the table than its value on the graph when x = 11?
(answers)
110
150
215
275
Answer:
if x = 11 then y = 660
Step-by-step explanation:
when the x increases by 1 at a constant rate, the y increases by 60 at a constant rate
so, if we keep moving forward with the table, you'll easily see that when x = 11, y = 660
The value of y would be 275 more in the table than on the graph when x = 11. Hence the correct option is 4.
The value of y would be 275 more in the table than its value on the graph when x = 11.
By substituting x = 11 into the equation y = 10 + 2x, we get y = 10 + 2(11) = 32 for the graph.
From the table, the corresponding value for y when x = 11 is 307.
Thus, the difference in the value of y between the table and the graph is 307 - 32 = 275.

The local pizzeria offers a choice of 2 pizzas - supreme or vegetarian, 3 sides - chips, salad
or coleslaw, and 4 drinks - juice, coke, ginger beer or water. For dinner I decide to have
1 pizza, 1 side, and 1 drink. How many possible meals do I have to choose from?
Answer:
24
Step-by-step explanation:
To determine the number of possible meal combinations at the pizzeria, multiply the number of options for each course, yielding 2 (pizzas) × 3 (sides) × 4 (drinks), which equals 24 possible meals.
Explanation:To calculate the number of possible meals you can choose from at the pizzeria, you can use the Fundamental Principles of Counting, specifically the Multiplication Principle. The principle states that if one event can occur in m ways and a second independent event can occur in n ways, then the two events can occur in m × n ways together. Since we are dealing with more than two events, we extend this principle.
In this scenario, you have 2 kinds of pizzas, 3 sides, and 4 drinks to choose from. To find the total combinations of meals, you multiply the number of options for each selection. That is:
Pizza options (2) × Side options (3) × Drink options (4) = Total meal options.So, the calculation would be:
2 × 3 × 4 = 24 possible meals.
This calculation shows that there are 24 different combinations of meals that you can choose from when you pick one pizza, one side, and one drink.
