Answer: Option D (0.833)
Step-by-step explanation:
There are 6 possible outcomes when the arrow is spun, and 5 of those outcomes correspond to the arrow landing on a number greater than 10 (the numbers 11, 12, 13, 14, and 15).
Therefore, the probability of the arrow landing on a number greater than 10 is 5/6, or about 0.833

. Which of the following equations
represents an identity? Justify your
choice.
1) 2x+1=3x+4
2) 4x-3=2(2x+7)
3) 6x+3=2x+10
4) 4(5x+2) = 20x+8
The correct equation which represent an identity will be;
⇒ 4(5x+2) = 20x+8
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
All the equations are,
1) 2x + 1 = 3x + 4
2) 4x - 3 = 2(2x + 7)
3) 6x + 3 = 2x + 10
4) 4(5x + 2) = 20x + 8
Now,
Solve each equation and find an identity as;
1) 2x + 1 = 3x + 4
⇒ 1 - 4 = 3x - 2x
⇒ - 3 = x
⇒ x = -3
Thus, It is not represent an identity.
2) 4x - 3 = 2(2x + 7)
⇒ 4x - 3 = 4x + 14
⇒ - 3 ≠ 14
Thus, It shows no solution.
3) 6x + 3 = 2x + 10
⇒ 6x - 2x = 10 - 3
⇒ 4x = 7
⇒ x = 7/4
Thus, It is not represent an identity.
4) 4(5x + 2) = 20x + 8
⇒ 20x + 8 = 20x + 8
⇒ 20x - 20x = 8 - 8
⇒ 0 = 0
Clearly, '0' is an additive identity.
Thus, This equation shows an identity.

Ms. Michaels surveyed her class on whether they preferred free time at the beginning of class or at the end of class. If the ratio of students who prefer free time at the beginning of class to students who prefer free time at the end of class is 13 over 17, what does the ratio 13 over 17 represent?
Answer:
Step-by-step explanation:
Based on the fact that Ms. Michaels surveyed her class on whether they preferred free time at the beginning of class or at the end of class and found that students who prefer free time at the end of class are 12 over 19, the thing which the ratio 12 over 19 represents is C. 12 students prefer free time at the beginning of class, and 19 students prefer free time at the end of class.
What is a Ratio?
This refers to the quantitative relation that is used to show the relation between two variables, which shows the number of times one is contained in the other.
Hence, it can be seen that based on the result of the survey by Ms. Michaels about the preference of the students about free time at the beginning of class or at the end of class, the meaning of the ratio is that 12 students prefer free time at the beginning of class, and 19 students prefer free time at the end of class.
Answer:
Step-by-step explanation:
the ratio 13 over 17 represents how many students preferred free time at the beginning of class to how many students preferred free time at the end of class.a little extra: more people want free time at the end of class than at the beginning
Mr Espinoza randomly chooses one of five toll booths when entering a toll road when driving to work. What is the probability he will select the middle toll booth on Monday and Tuesday
The probability that Mr. Espinoza will select the middle toll booth on Monday and Tuesday is 8%.
What is the probability?Probability refers to the odds of Mr. Espinoza selecting the middle toll booth on Monday and Tuesday when he could have selected toll booths 1, 2, 4, or 5.
The chances of selecting one out of five toll booths = 1/5 or 0.2
The likelihood of Monday and Tuesday out of the five working days = 2/5 or 0.4

By solving the given factorial question we get a+b=2538.
How does factorial work?In mathematics, the term "factorial" refers to the sum of all positive integers that are less than or equal to a specific positive integer, which is followed by an exclamation point. Thus, factorial seven is denoted by the symbol 7!, which stands for 1 2 3 4 5 6 7. Factorial 0 is equal to 1 by definition.
Solution:-
We can factor each of these numbers.1! + 2! = 1! ( 1 + 2 )
2! + 3! = 2! ( 1+ 3 )
3! + 4! = 3! ( 1 + 4 )
4! + 5! = 4! ( 1 + 5 )
5! + 6! = 5! ( 1 + 6 )
6! + 7! = 6! ( 1 + 7 )
7! + 8! = 7! ( 1 + 8 )
8! + 9! = 8! ( 1 + 9 )
Once again:
1! + 2! = 1! ( 3 )
2! + 3! = 2! ( 4 )
3! + 4! = 3! ( 5 )
4! + 5! = 4! ( 6 )
5! + 6! = 5! ( 7 )
6! + 7! = 6! ( 8 )
7! + 8! = 7! ( 9 )
8! + 9! = 8! ( 10 )
We can split the number into two parts, a! * bThe LCM of 1!, 2!, 3!, ... , 8! is 8!
The LCM of 3, 4, 5, ... , 10 is 2520
The LCM is 2520 * 8!
a = 2520
b = 8
a + b = 2528

Answer: So the positive solution is:
ANSWER: X = 5
(x = 5 ), (x = - 2 )
Step-by-step explanation:
when 10 is subtracted from the square of a number the result is 3 times the number.
Find the positive solution.
Let: x = number
Let x^2 = square of a number.
x^2 - 10x = 3x transpose
x^2 - 3x - 10 = 0
Apply Factoring: Fractions of 10 are 5 and 2
( - 5)(2) = - 10
- 5 + 2 = - 3
( x - 5 )(x + 2) = 0
x - 5 = 0 x + 2 = 0
x = 5 x = - 2

Y =. 444 (8. 5) minus 21. 29. 2. Y = 3. 774 minus 21. 29. 3. Y = negative 17. 52. Ramona determined that her answer was incorrect because a man who is –17. 52 inches tall does not make any sense. What was Ramona’s mistake? She substituted the 8. 5 for the wrong variable. She should have added. 444 and 8. 5. The value for y should be positive. The solution of –17. 52 should be the shoe size
Ramona’s mistake was she just substituted the 8.5 for the wrong variable.
From given conditions:
Ramona used the regression equation y = 444x - 21.29,
where x represents height and y represents shoe size,
According to Romana her answer is incorrect as a man who is -17.52 inches tall does not predict the approximate height of a man.
The 8.5 refer to shoes size, not height.
So substituting 8.5 for the x-variable is wrong, because x refers to height and y represents shoe size.
Therefore, Ramon just substituted the 8.5 for the wrong variable. She must replace 8.5 for y-variable, because that's the right one for shoe size.

What is velocity?Simply said, velocity is the rate of movement in a certain direction. such as the speed of a car driving north on a highway or the pace at which a rocket takes off.
Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. Since acceleration is only the rate at which velocity changes, acceleration is likewise a vector quantity.
Given that,
initial velocity (u) = 30 m/s
acceleration (a) = - 6 m/s²
As we know,
v² = u² + 2as

A traffic study has shown that the probability that 5 cars will pass over a small bridge in a 4-minute period is 0.16.
What are the odds against exactly 5 cars passing over the bridge in that time?
Answer: The odds against an event occurring are the ratio of the probability that the event will not occur to the probability that the event will occur. To find the odds against an event, you can use the formula:
Odds against = (1 - probability of event occurring) / probability of event occurring
In this case, the event is that exactly 5 cars will pass over the bridge in a 4-minute period. The probability that this event will occur is 0.16. Therefore, the odds against this event occurring are:
Odds against = (1 - 0.16) / 0.16
= 0.84 / 0.16
= 5.25
So, the odds against exactly 5 cars passing over the bridge in a 4-minute period are 5.25 to 1.
It means that there are 5.25 times more likely that it will not happen compare to happen.

In the given pairs of polygons the scale factor of figure A to figure B is 2:4.
How is scale factor calculated?The scale factor is calculated using the following fundamental formula: Scale factor = Dimension of the new shape Dimension of the old shape. The formula for calculating the scale factor is expressed as Scale factor = Larger figure dimensions Smaller figure dimensions in the event that the original figure is magnified.
The ratio of a smaller figure's side to its corresponding side in the bigger figure is the scale factor between the two figures.
As a result, the smaller figure's side length of 4 units and its side length of 10 units are equivalent.
Therefore:
Scale factor = 4:10
i.e. 2:5
Simplify
Scale of the smaller figure to the larger is equal to 2:4.
