The sections on the spinner are used to illustrate probability
The reasonable possible outcome is that the expected outcomes of the red section and the yellow sections are the same
How to determine the possible outcomesThe sections in the spinners are:
Red = 1Blue = 2Yellow = 1Total = 4From the above parameters, the probability of each section is:
P(Red) = 1/4
P(Blue) = 1/2
P(Yellow) = 1/2
When the spinner is spun 1000 times, the expected outcomes are:
Red = 1/4 * 1000 = 250
Blue = 1/2 * 1000 = 500
Yellow = 1/4 * 1000 = 250
From the above calculations, we can determine that the reasonable possible outcome is that the expected outcomes of the red section and the yellow sections are the same

Step-by-step explanation:
Plot the given parabola on the axes. Plot the roots, the vertex and two other points.
y=−x2+2x+48
To plot the parabola y = -x² + 2x + 48, find the vertex at (1, 49), the roots at -6 and 8, and two additional points at (0, 48) and (2, 48). Then, plot these points on a graph and sketch the parabola.
Explanation:To plot the given parabola y = -x² + 2x + 48, we must follow several steps:
Find the vertex. The formula for the x-coordinate of the vertex is -b/2a. In this equation, a = -1 and b = 2, so the x-coordinate is -2/-2 = 1. Substituting x = 1 into the equation gives us y = -12 + 2 * 1 + 48 = 49. So, the vertex is (1, 49). Find the roots. The roots are the x-values when y = 0. We solve -x2 + 2x + 48 = 0. Factoring the quadratic can give us the roots, but this equation doesn't factor nicely. We use the quadratic formula instead: x = [-b ± sqrt(b2 - 4ac)] / 2a = [-2 ± sqrt((2)2 - 4*(-1)*48)] / 2*(-1). This gives us two roots, -6 and 8. Choose two other points. Let's choose x = 0 and x = 2. When x = 0, y = 48. When x = 2, y = -22 + 2 * 2 + 48 = 48. So, the two other points are (0, 48) and (2, 48). Plot these points on a coordinate grid and draw the parabola.Learn more about Plotting Parabola here:

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.

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.

Answer:
-1/14
Step-by-step explanation:
To simplify the expression, you should first divide up the parts to make it easier. Multiply 1/5 by -5/7 first. When you multiply the two fractions, the fives cancel out since there is a five in both the numerator and the denominator. This leaves us with just -1/7.
[tex]\frac{1}{5} *\frac{-5}{7} =\frac{-1}{7}[/tex]
Now, multiply -1/7 by 2/4. Notice that you can simplify 2/4 to 1/2. You can't cancel out anything in this expression so simply multiply the two fractions.
[tex]\frac{-1}{7} *\frac{1}{2} =-\frac{1}{14}[/tex]

Step-by-step explanation:
The phrase 'ten less than 40% of a number is -4' can be translated into a mathematical equation as 0.4x - 10 = -4. By using the rules of algebra, we can simplify this equation to find that the unknown number x equals 15.
Explanation:The question deals with an equation involving the term 'ten less than 40% of a number'. This phrase can be translated into a mathematical equation as follows: 0.4x - 10 = -4, where x is the unknown number we're trying to find.
Following the rules of algebra, you would want to simplify this equation as much as possible. Let's add 10 to both sides of the equation, which gives us 0.4x = 6. To isolate 'x', we divide both sides of the equation by 0.4, which gives us x = 6 / 0.4. When you perform this division, you find that x = 15.
Thus, the number that 'ten less than 40% of' equals -4 is 15.

Square root of -3
find the square root of -3
Answer:
i times the square root of 3
Step-by-step explanation:
Whenever you take a square root of a number, look for anything that you could take out! Like if you have the square root of 40, that’s 4 * 10, so you could take out a 2 from the square root and leave the 10.
In this, we see that it’s the square root of 3 times the square root of -1, which we can simplify to the square root of 3 times “i.” We use i to represent the square root of -1.
I NEED HELP IMMEDIATELY!!! Allen has four times as many cards as Bob, and Jane has twice as many cards as Allen. Together, Allen and Jane have 468 cards. How many cards do Allen, Jane, and Bob each have?
Answer:
Allen- 144 cards
Jane- 288 cards
Bob- 36 cards
Step-by-step explanation:
Here's what we know:
a = 4b (Allen has 4 times Bob's cards)
j = 2a (Jane has twice Allen's)
a + j = 432 (Allen and Jane have 432 cards all together)
Start with substituting:
4b + 2a = 432
4b + 2(4b) = 432
Distribute:
4b + 8b = 432
Simplify:
12b = 432
Divide both sides by 12:
b = 36
To find how much Allen has just multiply 36 times 4.
a= 144 cards
To find how much Jane has multiply 144 times 2.
j= 288 cards
Answer:
156
312 and
39
Step-by-step explanation:
Let Allen be A , Jane be J and Bob be B
Allen has 4 times as Bob
So
A = 4B
Jane has twice as Allen
So
J = 2A
Together, Allen and Jane has 468 cards
A + J = 468
Substitute 2A for J in the third equation.
We have
A + J = 468
A + 2A = 468
3A = 468
Divide both sides by 3
3A/3 = 468/3
A = 156
Recall
A = 4B
Therefore
156 = 4B
Divide both sides by 4
156/4 = 4B/4
39 = B
B = 39
Also,
J = 2A
J =2 x 156
J = 312
Allen has 156 cards
Jane has 312 cards and
Bob has 39 cards

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.
