An algebraic representation which best describes this transformation is: C. (x, y) → (5x/2, 5y/2).
What is dilation?In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
By critically observing the graph, we can logically deduce the following vertices:
Coordinate P = (-1, 1)Coordinate Q = (2, 0)Coordinate R = (-1, -2)Coordinate P' = (-5/2, 5/2)Coordinate Q' = (5, 0)Coordinate R' = (--5/2, -5)In this scenario, the transformation rule is given by this algebraic representation:
Q (x, y) → Q' (x, y)
Coordinate Q = (2, 0) → Coordinate Q' = ((5/2 × 2), (5/2 × 0)) = Coordinate Q' = (5, 0).

If you are tossing a six-sided die, what is the probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss?.
Answers
A six sided dice is tossed twice. The probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9 .
A dice has six faces or sides and it is throws twice . When a dice is toss first time,
Total possible outcomes on toss = 6 ={ 1,2,3,4,5,6}
In our first toss we want to get 1 or 2
So, favourable outcomes of getting 1 or 2 = 2
Probability of getting 1 or 2 on first toss= favourable cases /total outcomes = 2/6 = 1/3
For second toss, we want to get a1 or a2 again.
Total possible outcomes = 6
Probability of getting a1 or a2 on second toss= 2/6= 1/3
Now, Multiply these probsbilites togethers and chance of getting 1 or 2 on first and second which is 1/3× 1/3 = 1/9
Hence , probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9.

A telecommunications company will be laying new fiber optic cables underground. One cable will be perpendicular to the road shown, passing through the point ( 7, 2 . At what point will the cable pass through the road?
Answers
The point at which this cable would pass through the road shown is at the y-intercept of (0, -17/2).
How to determine an equation and the point on this perpendicular line?Mathematically, the slope of a straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
By critically observing the road shown in the graph above, the points on the line include the following:
Points (x, y) = (0, -2)
Points (x, y) = (-3, 0)
Substituting the given points into the formula, we have;
Slope, m = (0 + 2)/(-3 - 0)
Slope, m = 2/-3
Slope, m = -2/3.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
-2/3 × m₂ = -1
-2m₂ = -3
m₂ = 3/2
At point (7, 2), a linear equation for the line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represent the points.c represents the y-intercept.Substituting the given points into the formula, we have;
y - 2 = 3/2(x - 7)
y - 2 = 3x/2 - 21/2
y = 3x/2 - 21/2 + 2
y = 3x/2 - 17/2
At the y-intercept of (0, -17/2), the cable pass through the road.

In one day, the bakery made 719 bagels. The bagels were divided into 9 equal shipments. A few bagels
were left over and given to the baker. How many bagels did the baker get?
Answers
719 bagels / 9 crates = 79 bagels per crate.
now that we know that there are 79 bagels per crate, we can multiply by the number of crates to see how many bagels were shipped out in total
9 crates * 79 bagels per crate = 711 bagels
now, we subtract how many bagels were made by how many were shipped to see how many are left.
719-711 = 8 bagels. this value makes sense because there is not enough bagels left to add an equal amount to each crate.
hope this helps!
Answer:
8 bagels
Step-by-step explanation:
This is a remainder division problem. We need to divide 719 by 9 and find the remainder.
First off, 9 is bigger than 7, so we need to move to the next digit. How many times does 9 go into 71? 9 times 7 is 63! That's the closest smaller number we can get, so I will write a 7 in the long division problem above the 1. I will subtract 63 from 71 to get 8.
7
9 | 719
-63
8
Now, the 9 can be brought down, making our 8 into an 89. How many times does 9 go into 89? 9 times 9 is 81! That's the closest we can get! I will write a 9 by the 7 above the 9 in 719, and write 81 below the 89. Subtracting these leaves us with a remainder of 8.
79
9 | 719
-63 ↓
89
-81
8
This means that the bagels were sent in 9 equal shipments of 79 bagels each, and the baker was left with 8 bagels!
it takes an airplane 1 hour 30 minutes to fly 600 km against the wind. the return trip with the wind takes only 1 hour. find the total flying time for the round trip if there was no wind.
Answers
The total flying time for the round trip if there was no wind would be 2 hours 24 minutes. The result is obtained by using the elimination method.
What is elimination method?The elimination method is a method for solving system of linear equations where we eliminate one variable so that we can get an equation in one variable. In doing that, we can either add or subtract the equations.
Given the case that an airplane takes 1 hour 30 minutes to fly 600 km against the wind. It takes only 1 hour in the return trip.
What would be the total flying time for the round trip if there was no wind?
Let's say:
v = the speed of the airplanew = the speed of the windWhen the airplane leaves,
v - w = 600 km / 1.5 hour
v - w = 400 kph ... (equation 1)
When the airplane returns,
v + w = 600 km / 1 hour
v + w = 600 kph ... (equation 2)
We eliminate the equation 2 and 1 to get the speed of the airplane.
v - w = 400 kph
v + w = 600 kph +
2v = 1000 kph
v = 1000 ÷ 2
v = 500 kph
For the round trip, the airplane would fly 600 × 2 = 1200 km.
The total flying time if there was no wind would be
t = s/v
t = 1200/500
t = 2.4 hour
t = 2 hours 24 minutes
Hence, the total flying time for the round trip if there was no wind is 2 hours 24 minutes.

Area using sine formulaA = 1/2ab·sin(C)
A = 1/2(12 cm)(8 cm)·sin(26.4°) ≈ 21.34 . . . . square units
Area using Heron's formulaThe semiperimeter is ...
s = (6 +8 +12)/2 = 13
The area is ...
A = √(s(s -a)(s -b)(s -c))
A = √(13·(13 -12)(13 -8)(13 -6)) = √(13·1·5·7) = √455
A ≈ 21.33 . . . . square centimeters
The area of the triangle is about 21.3 cm².

The problem with over specifying the dimensions of a geometry problem is that it is often difficult to make them consistent. Here, the area values agree to three significant figures. That is about all we can expect, given the angle precision is 3 significant figures.

Lets solve for x.
Simplify the right side of the equation.
Cancel the common factor of 2 and 6 .
Factor 2 out of 2 .
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2(1)}{2(3)}[/tex]
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{1}{3}[/tex]
Combine the numerators over the common denominator.
[tex]x-\frac{2}{5}=-3x-\frac{2-1}{3}[/tex]
[tex]x-\frac{2}{5}=-3x-\frac{1}{3}[/tex]
Move all terms containing x to the left side of the equation.
Add [tex]3x[/tex] to both sides of the equation.
[tex]x-\frac{2}{5}+3x=\frac{1}{3}[/tex]
Add [tex]x[/tex] and [tex]3x[/tex].
[tex]4x-\frac{2}{5}=\frac{1}{3}[/tex]
Move all terms not containing x to the right side of the equation.
Add [tex]\frac{2}{5}[/tex] to both sides of the equation.
[tex]4x=\frac{1}{3}+\frac{2}{5}[/tex]
To write [tex]\frac{1}{3}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{5}{5}[/tex] .
[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}[/tex]
To write [tex]\frac{2}{5}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{3}{3}[/tex]
[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}*\frac{3}{3}[/tex]
Simplify.
Write each expression with a common denominator of 15 , by multiplying each by an appropriate factor of 1 .

The scale of a map is 1:20 000. What area does 8 cm² represent?
Answers
The 8 cm² area on a map represent the actual area = 3200000000 cm² .
Scale factor of a map
S = 1/20000
The scale factor for area is found by squaring the scale factor for length. Thus the scale factor for area is S^2
When applied to the area we consider S^2 as a scale factor.
The area on the map = 8 cm²
So The actual area = 8 × (20000)^2 = 8× 20000×20000
=3200000000 cm² = 320000 m² =32 hectare.

Simplify your answer as much as possible.
Answers
Solving the inequality -6.6 < 1.7 + u for u, the solution is simplified as: u > -8.3 or -8.3 < u.
What is an Inequality?In maths, an inequality is defined as a statement that is used to compare two quantities that are unequal. For example, we can state that 5 is greater than 3 + 1, or 5x is less than 4x + 3x. We can equally state that a given value of a variable can be equal to or greater than a number, and so on.
Basically, we are comparing two unequal quantities when we state inequalities.
Given the inequality, -6.6 < 1.7 + u, we are asked to solve the inequality for u. That is, we need to find the possible value that u represents in the inequality or that would make the inequality true.
Therefore:
-6.6 < 1.7 + u
Subtract 1.7 from both sides

A fruit seller bought oranges at rs 48 per dozen. At what price should he sell 30 oranges so as make 10%profit
Answers
Answer:
132 rs
Step-by-step explanation:
Cost of one orange = 48 : 12 = 4 rs
cost of 30 orange = 4 * 30 = 120 rs
10 : 100 = x : 120
x = (120 * 10)/100
x = 12 rs
final price = 120 + 12 = 132 rs
the 3 conditions for sampling distributions must be met in order to calculate p-hat. group of answer choices true false
Answers
The correct answer is False because, If the sample size is large enough (n greater than or equal to 30) the sampling distribution is approximately normal regardless of the shape of the population.
The sample fraction, often called the "p-hat", is the ratio of the number of sample successes to the size of the sample. The standard deviation of (p) decreases as the sample size n increases. This is because n is included in the denominator of the standard deviation formula. That is, (p has) has fewer variables for larger samples. The P-hat (must be a lowercase p with a caret (^) circumflex) indicates the percentage of the sample (this is the x-bar, the average of the samples).
A p-hat (proportion) sampling distribution is a collection of equal-sized repeated sample proportions drawn from the same population to represent it. According to the central limit theorem, the sampling distribution of p-hat is approximately normally distributed for large sample sizes.

f(x) = 2x; translate up 5 units, reflect in x-axis.
Answers
After f(x) = 2x translated up 5 units, then it reflect in x-axis is g(x) = f(2x)+5.
What does a graphing translation mean?
A graph can be vertically translated by moving the base graph up or down in the y-axis direction. Each point on a graph is moved k units vertically to translate the graph by that many units.The rules for transforming a function f(x) into g(x):
g(x) = a·f(b(x-c)) + d
a = vertical dilation (stretch); reflects across x-axis if negativeb = horizontal dilation (stretch); reflects across y-axis if negativec = horizontal translation (shift); shift right if c is positive, left if c is negatived = vertical translation; up if d is positive, down if d is negativeHence, After f(x) = 2x translated up 5 units, then it reflect in x-axis is g(x) = f(2x) + 5.

The graph of the function, f(x) = x2 - 5x - 7 opens
and has a
value.
Answers
The parabola has a positive leading coefficient, which means that it opens upwards.
The graph opens up or down?We want to find the leading coefficient and see how the parabola opens.
A general quadratic equation is written as:
y = A*X^2 +b*X+ c
Where a is the leading coefficient.
If a is positive, then the parabola opens upwards, and if a is negative, the parabola opens downwards.
In this case, the equation is:
y = x^2 - 5x - 7
The leading coefficient is a = 1, it is positive, so the parabola opens upwards.
