Answer:
Step-by-step explanation:
Y=2
Reflection of a rectangle over the x-axis (y = 0) will generally cause it to map onto itself. The other given lines (y = 2, y = x, and y = 2x) will not typically have this result, unless the rectangle is specifically located on the plane.
Explanation:In geometry, a shape maps onto itself under reflection when it is reflected over a line that bisects it symmetrically. With a rectangle, this can occur when it is reflected over the x-axis or y-axis, assuming the rectangle's sides are parallel to the axes. From the given options, only y = 0 (x-axis) could create this type of reflection.
Reflection over the line y = 0 will leave a rectangle in the same position if its height is evenly distributed above and below the x-axis. For lines like y = 2, y = x, and y = 2x, they would not bisect a rectangle symmetrically unless the rectangle is specifically positioned, so they will not generally result in the rectangle mapping onto itself.

Answer:
Question1: 58660
Question 3: 7244
Step-by-step explanation:
Question 1: My 5 is worth 50,000 means the number will start with 5 and will be between 50,000 and 60,000, thus will have 5 digits in total
My 8 is worth 8,000 means the next number is 8
One of my 6s is worth 60 means there is more than one 6. One 6 is worth 60 and the other is 10times as much so 600. The other digit is a 0. So those 3 together are 660.
The entire number is 58660
Question 3: The number has 4 digits:
My 7 is worth 7000 so the number will be between 7,000 and 8,000.
My 2 is worth 200 so.
One of my 4s is worth 40. So this means there is another 4.
The other number is 1/10 of 40, which is 4.
The total is 7244

the mean decreases by 1.9
the mean decreases by 2.4
the mean decreases by 1.9
there are no outliers
Answer: The mean increases by 2.1
Step-by-step explanation:
According to the given description (dots are denoting the frequency for each value), the given data is :-
50 , 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82
[Note - We take 79 as the value between 78 and 80, 81 as between 80 and 82 ]
Mean = [tex]\overline{x}_1=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex] (1)
[tex]=\dfrac{1066}{14}=76.1428571429\approx76.1[/tex]
First Quartile: [tex]Q_1=[/tex] Median of the lower half ( 50 , 72, 72 , 74, 76 , 78 , 79 )
= 74
Third Quartile: [tex]Q_3=[/tex] Median of the upper half ( 79 , 79 80, 81, 82, 82, 82 )
= 81
Interquartile range (IQR)=[tex]Q_3-Q_1=81-74=7[/tex]
According to the IQR rule,
Upper limit = [tex]1.5\times IQR+Q_3=1.5\times7+81=91.5[/tex]
Lower limit = [tex]Q_1-1.5\times IQR=74-1.5\times7=63.5[/tex]
Since 50 < 63.2 , so 50 is outlier .
When 50 is removed from the data , the new data will be 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82
Mean = [tex]\overline{x}_2=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex]
[tex]=\dfrac{1016}{13}=78.1538461538\approx78.2[/tex] (2)
Change in mean from (1) and (2)
[tex]\overline{x}_2-\overline{x}_1\\\\=78.2-76.1=2.1[/tex]
Hence, the mean increases by 2.1.

and a y-intercept of -1.
Answer:
y = [tex]\frac{1}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (0, - 1) ← coordinates of intercepts
m = [tex]\frac{-1-0}{0=2}[/tex] = [tex]\frac{-1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]
The y- intercept is - 1 ⇒ c = - 1
y = [tex]\frac{1}{2}[/tex] x - 1

A car can travel 120 miles on 30 litres of petrol .work out how far the same car can travel on 35 litres of petrol
Answer:
140 miles.
Step-by-step explanation:
The distance the car travels on 1 litre= 120/30 = 4 miles.
So the distance for 35 litres = 4 * 35 = 140 miles.
The car's fuel efficiency is calculated as 4 miles per liter based on the given data. Using this, it is determined that the car can travel 140 miles on 35 liters of petrol.
Explanation:To calculate how far a car can travel on 35 liters of petrol, we need to determine its fuel efficiency, which is the distance it can cover per unit volume of fuel. Based on the given that the car can travel 120 miles on 30 liters of petrol, we can write an equation to represent the car's fuel efficiency:
Fuel efficiency = Distance/Volume of fuel = 120 miles / 30 liters = 4 miles per liter
Now that we have the car's fuel efficiency, we can find out how far it can travel on 35 liters of petrol:
Distance on 35 liters = Fuel efficiency × Volume of fuel = 4 miles/liter × 35 liters
Distance on 35 liters = 140 miles
Therefore, the car can travel 140 miles on 35 liters of petrol.

The length of one side of the cube is 4 feet.
What is a cube?In Geometry, a Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.
The given volume of the cube is,
V = 64 cubic feet
Let a be the length of each side of the cube.
Therefore volume V of the cube is given as,
V = (side)³
or, V = a³
Since, V = 64 cubic feet
Therefore,
a³ = 64 cubic feet
Taking cube root both the side we get,
∛a³ = ∛64 cubic feet
or, a = ∛64 cubic feet
Since, ∛64 = 4
Therefore,
a = 4 feet
which is the length of one side.

2(4-8x)+6=-1 interpreting experiessions
Answer:
X = [tex]\frac{13}{16}[/tex]
Step-by-step explanation:
2 (4-8x) + 6 = 1
Multiply parentheses by 2
8 - 16x + 6 = 1
add (8 + 6)
14 - 16x = 1
Move constant to right and change its sign
-16x = 1 -14
Calcualte te difference
-16x = -13
divide bot sides by -16
x = [tex]\frac{13}{16}[/tex]
The given equation 2(4-8x)+6=-1, distribute the 2, combine like terms, and then isolate x to find that x = 15/16.
The student has provided an equation 2(4-8x)+6=-1 and requires help solving for x. To solve this equation, we first distribute the 2 across the terms in the parenthesis:
8 - 16x + 6 = -1.
Combine like terms:
14 - 16x = -1.
Subtract 14 from both sides:
-16x = -15.
Divide both sides by -16:
x = 15/16.
Therefore, the solution is 15/16.
Complete Question: Solve the equation 2(4-8x)+6=-1 using Method 2 (interpreting expressions as a single quantity).

How many times does 27 go into 70?
Answer: 27 can go in completely to 70 twice, or, if you want an exact decimal, 2.5925 (...it goes on and on) times
Step-by-step explanation: what you have to do is divide, 70 divided by 27. What “go into” means is to divide, always. What division does is show how much a number can fit inside another one. For example, 4 divided by two. If four is split into two equal parts, you get two. So four divided by two is two.
The exact same thing is happening in this situation; except with bigger numbers that don’t go into each other evenly.
So, the answer is approximately two or exactly 2.59..
The number 27 goes into 70 a total of 2 whole times when only considering whole numbers. The result of dividing 70 by 27 gives approximately 2.59 if we take decimals into account.
Explanation:The question is asking how many times does 27 go into 70. In other words, this is a division problem where 70 is the dividend (the number being divided) and 27 is the divisor (the number we are dividing by).
To find the answer, we simply divide 70 by 27. Using a calculator, we find that 70 divided by 27 equals approximately 2.59.
However, if we're only counting whole times, we only count the number before the decimal point. Therefore, 27 goes into 70 a total of 2 whole times.

One car travels 25 km/h faster than another. In the same time that one goes 120 km, the other goes
220 km. Find their speeds.
Answer:
Speed of first car = 30 km/h and speed of second car = 55 km/h
Step-by-step explanation:
Speed = distance/time
Given: distance travelled by one car = 120 km
Distance travelled by second car = 220 km
Now let speed of first car be x km/h.
∴ Speed of second car = (x + 25) km/h (∵ One car travels 25 km\h faster than another)
Now, if the time is constant, then ratio of distance to speed of first car will be equal to the ratio of distance to speed of another car. e.g.,
[tex]\frac{distance\ travelled\ by\ first\ car}{speed\ of\ first\ car} = \frac{distance\ travelled\ by\ second\ car}{speed\ of\ second\ car}[/tex]
[tex]\frac{120}{x} = \frac{220}{x+25}[/tex]
[tex]220x = 120 (x +25)[/tex]
[tex]220x = 120x + 3000[/tex]
[tex]100x = 3000[/tex]

∴ Speed of first car = 30 km/h
Speed of second car = (30 + 25) = 55 km/h.
