Answer:
[tex]-3m^{12}{n^{6} }[/tex]
Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:
[tex]\frac{-3m^{5}n^{4} }{m^{-7} n^{-2} }[/tex]
We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:
[tex]\frac{-3m^{5+7} n^{4+2} }{1}[/tex]
Now, simplifying this gets:
[tex]-3m^{12}{n^{6} }[/tex]

The requried mean absolute deviation is given as 1.625.
What is Statistic?The statistic is the study of mathematics which deal with relations between comprehensive data.
Here,
Average of the given number = 25 + 23 + 23 + 24 + 25 + 26 + 27 +27 / 8
= 197 / 8
Average = 24.625
mean absolute deviation (MAD) = 1/n ∑[xi - average]
mean absolute deviation (MAD) = [|22 - 24.625| + |23 - 24.625|+|23 - 24.625|+|24 - 24.625|+|25 - 24.625|+|26 - 24.625|+|27 - 24.625|+|27 - 24.625|]/8
mean absolute deviation (MAD) = [2.625+1.625+1.625+0.625+0.375+1.375+2.375+2.375]/8
mean absolute deviation (MAD) = 13 / 8 = 1.625
Thus, the requried mean absolute deviation is given as 1.625.

At a carnival, $2,914.25 in receipts were taken at the end of the day. The cost of a child’s ticket was $20.50, an adult ticket was $29.75, and a senior citizen ticket was $15.25. There were twice as many senior citizens as adults in attendance, and 20 more children than senior citizens. How many children, adult, and senior citizen tickets were sold?
Answers
Answer:
"x" children tickets are 70, "y" adult tickets 50 and "z" senior citizen tickets 25
Step-by-step explanation:
With the information of the statement we can pose the following equations:
we have to "x" children tickets, "y" adult tickets and "z" senior citizen tickets.
20.5*x + 29.75*y + 15.25*z = 2914.25
we also have to:
z = 2*y
plus that:
x = z + 20, replacing, we have left:
x = 2*y + 20
now, we replace each other in the main equation:
20.5*( 2*y + 20) + 29.75*y + 15.25*(2*y) = 2914.25
41*y + 410 + 29.75*y + 30.5*y = 2914.25
101.25*y = 2504.25
y = 2504.25/101.25
y = 24.73
z= 2*24.73 = 49.46
x = 2*24.73 + 20
x = 69.46
"x" children tickets are 70, "y" adult tickets 50 and "z" senior citizen tickets 25
Answer:
Children tickets = 69.4667
Adult tickets = 24.7333
Senior tickets = 49.4667
(The decimal does not make sense as we cannot have a fractional amount of tickets, but with the information given, this is the correct answer)
Step-by-step explanation:
Let's call the amount of children C, the amount of adults A and the amount of seniors S. Then, we can write the following system of equations:
C*20.5 + A*29.75 + S*15.25 = 2914.25 (eq1)
S = 2*A (eq2)
C = S + 20 (eq3)
Using eq2 in eq3, we have:
C = 2*A + 20 (eq4)
Using eq2 and eq4 in eq1, we have:
(2*A + 20)*20.5 + A*29.75 + 2*A*15.25 = 2914.25
41*A + 410 + 29.75*A + 30.5*A= 2914.25
101.25*A = 2504.25
A = 2504.25 / 101.25 = 24.7333
Now using eq2, we have:
S = 2*A = 49.4667
And using eq4, we have:
C = 2*A + 20 = 69.4667
(The decimal does not make sense as we cannot have a fractional amount of tickets, but with the information given, this is the correct answer)
What is the value of x?
A;108
B;72
C;18
D;36
Answers
The value of x is 36°.
Given Information:
- The angle at the top of the star is labeled [tex]\(72^\circ\).[/tex]
- There is an angle labeled BFC on line AFC.
Angle Sum Property:
- The sum of the angles formed on a line is [tex]\(180^\circ\).[/tex]
Equation Setup:
- The angles BFC and [tex]\(72^\circ\)[/tex] are part of the line AFC.
- So, [tex]\(BFC + 72^\circ = 180^\circ\).[/tex]
Isolate the Unknown Angle:
- Subtract [tex]\(72^\circ\)[/tex] from both sides of the equation:
[tex]\[BFC = 180^\circ - 72^\circ\].[/tex]
Expression for BFC:
- Simplify the expression to find the measure of BFC:
[tex]\[BFC = 108^\circ\].[/tex]
6. Variable x:
- The angle BFC is expressed in terms of x: BFC = 3x.
Equation Setup for x:
- Set 3x equal to the known value of BFC:
[tex]\[3x = 108^\circ\].[/tex]
Solve for x:
- Divide both sides by 3:
[tex]\[x = \frac{108^\circ}{3} = 36^\circ\].[/tex]
Therefore, the value of [tex]\(x\) is \(36^\circ\).[/tex]

Cone and cylinder are two of the objects shown below could we slice diagonal to their bases/faces to create an ellipse cross-section.
What is an ellipse?The asymmetrical oval shape is drawn by a spot advancing along a plane so that the sum of its distance from foci is kept the same, known as an ellipse.
A circle is created by cutting at a right angle to the axis. An ellipse is created by cutting at an angle that is more than the angle created by the side of the cone but less than the right angle to the axis.
Every plane that a circular cylinder cross is at a straight angle to its axis. The cylinder is intersected in a curve that resembles an ellipse by a plane that is neither parallel to nor at right angles to the axis.

Find the percent of the number.

Explain your method.
Answers
Answer:
The answer would be 9
Step-by-step explanation:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$30=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore, 30% of 30 is 9
Answer:
30%of 30 is 9
Step-by-step explanation:
first you change 30% into a decimal (.30) by moving the decimal over to the left two times.
next you multiply 30* .30 ( i recommend you multiply it like this 30.00)
.30
next your first answer should be 900.00 . when you get this answer move the decimal over to the left two time again and your answer look like 9.0000
which is 9 as your final answer :).
Find the surface area of the pyramid
Answers
Answer:

Surface area is the area of all the sides
The area of the rectangular base is W x L = 30 x 30 = 900
Then to find the area of the triangles its [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex] 30 x 20
A = [tex]\frac{1}{2}[/tex] 600

How many x-intercepts will the graph of y = 3x2 + 6x + 3 have? (Use the discriminant to

A. 3 x-intercepts
B. 1 x-intercept
C. 2 x-intercepts
D. no x-intercepts
Answers
Answer:
i think D or B is the answer
Step-by-step explanation:
Answer:
B. 1 x-intercept
Step-by-step explanation:
We can use the discriminant expression, b²- 4ac, to answer this question.
In the equation y = 3x² + 6x + 3 we know that,
3 = a-value
6 = b-value
3 = c-value
Using this information, we can plug these numbers into the discriminant expression to find the discriminant.
6² - 4(3)(3) = 0
Because the value is equal to 0, we know there is 1 real solution and therefore there is 1 x-intercept.
HELP PLEASE!!!Describe the change in the graph of the parabola f(x) when it transforms into g(x) =1/2f(x)

The parabola g(x) will open in the opposite direction of f(x), and the parabola will be wider than f(x).
The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).
Answers
Answer:
D
Step-by-step explanation:
These are transformations. One thing to remember is that only a sign change (like a negative sign on the new function) will change the direction in which the parabola opens.
Here, going from f(x) to 1/2 * f(x) has no sign change, so the parabola will open in the same direction as before. Eliminate A and C.
Vertical transformations are those that are done to the entire function, as opposed to horizontal transformations which are done only on the x. Here, since we're multiplying 1/2 to f(x), we have a vertical transformation.
There are different transformations. The one here would be a vertical shrink by a factor of 1/2. Vertically shrinking a function is basically the same as compressing it, which would make it wider.
The answer is thus D.
Answer:
Last one:
The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).
Step-by-step explanation:
g(x) = ½f(x)
g(x) is obtained by a vertical stretch of f(x) by factor ½ (compression)
g(x) would look like f(x), would just be wider

2. A museum has an admission fee of $14 and averages 300 visitors per day. The museum board
decides to raise the fee. Research indicates that for every $1 increase, there would be 10 fewer
visitors per day. Keeping this in mind, the museum committee has found an equation that
represents revenue compared to the number of $1 increases. This relationship can be modeled by
the function: R= -10x2 + 160x + 4200, where R represents total revenue and x represents the
number of $1 increases above the starting fee of $14.
a) What is the maximum revenue possible for the museum?
b) How many $1 ticket increases will give the museum this maximum revenue?
c) What is the museum's revenue if they do not increase their fee?
Answers
Answer:
The answer to the questions asked is:
a) The maximum possible income for the museum is $4,840 per day.
b) The increase you must make to obtain the maximum income is $8 per ticket.
c) The income of the museum without increasing the fee is $4200.
Step-by-step explanation:
To solve all the questions asked, we must take into account the provided equation:
R = -10x2 + 160x + 4200The first question asks for the maximum income, that is, the maximum amount of money that can be obtained by making increases in the rate, despite the loss of people, so you must replace the X in the equation with values until instead of increase decrease:
R = -10 (1) 2 + 160 (1) + 4200 = 4350 R = -10 (2) 2 + 160 (2) + 4200 = 4480 R = -10 (3) 2 + 160 (3) + 4200 = 4590 R = -10 (4) 2 + 160 (4) + 4200 = 4680 R = -10 (5) 2 + 160 (5) + 4200 = 4750 R = -10 (6) 2 + 160 (6) + 4200 = 4800 R = -10 (7) 2 + 160 (7) + 4200 = 4830 R = -10 (8) 2 + 160 (8) + 4200 = 4840 R = -10 (9) 2 + 160 (9) + 4200 = 4830As you can see, when the increase is $9, the income falls, so the maximum income is $4,840, while it can be seen that it occurs with an increase of $8, which answers the second question.
For the third question, that is, the income of the museum without increasing the fee, you must remember that the variable X is the increase in the fee, therefore, if you want to obtain the income without an increase, it must be given a value of zero to the variable inside the equation, with which we obtain:
R = -10 (0) 2 + 160 (0) + 4200 = 4200Which is the equation of an ellipse centered at the origin with endpoints of Major and minor axes at: (0,-7), (0,7), (-3,0), (3,0)

Round to one decimal place
please help me
Answers
To calculate the length of CD, additional information about the geometric figure is necessary. Meanwhile, for operations like addition or subtraction, results should be rounded to the same number of decimal places as the number with the least decimal places.
Explanation:The student's question seems to refer to the relationship between angles in a geometric figure and determining the length of a side, specifically the length of CD, within that figure. However, to provide a correct and precise length of CD, more information from the geometric figure or additional conditions are required, such as side lengths or other angle measurements. As the question stands, it lacks sufficient data to calculate the length of CD.
Regarding rounding, in general when you are performing mathematical operations like addition or subtraction, the result should be rounded to the same number of decimal places as the number with the least number of decimal places. For example, if you were to add 5.123 to 2.5, the result should be rounded to one decimal place, since 2.5 has only one decimal place. The correct sum would be 7.6.

A dart hits the board. What is the probability that it will hit in Region II, as a decimal to the nearest tenth?
A) type in your fraction from step 3
B) p(region ll)= _____ (decimal to the nearest tenth)
Answers
We have been given a graph of a board. We are asked to find the probability that dart will hit in region II.
The probability that dart will hit the region II will area of region II over area of board.
Let us find area of region II. We can see that one side of region II is 35 and other is 20.
[tex]\text{Area of Region II}=35\times 20[/tex]
[tex]\text{Area of Region II}=700[/tex]
Length of board would be [tex]35+15=50[/tex]
Width of board would be [tex]20+8=28[/tex]
[tex]\text{Area of board}=50\times 28[/tex]
[tex]\text{Area of board}=1400[/tex]
[tex]\text{Probability that dart will land in region II}=\frac{700}{1400}[/tex]
[tex]\text{Probability that dart will land in region II}=\frac{1}{2}[/tex]
[tex]\text{Probability that dart will land in region II}=0.5[/tex]
Therefore, the probability that dart will land in region II is 0.5.
