Use the given vertices to graph quadrilateral TUVW and its image after a dilation centered at the origin with scale factor
k=2/3
T(9,-3), U(6,0), V(3,9), w(0,0)
Answers
Answer:We know that the dilation transformation of a figure either shrink or expand the original figure depending on the scale factor of the dilation.
As here we have scale factor=3>1.
Hence, the dilation changes the original will expand the original figure.
Hence, each of the coordinate of a figure get multiplied by 3.
Hence, the co
ordinates of the image are given as:
i.e. A(0,0) → A'(0,0)
B(2,3) → B'(6,9)
C(1,-2) → C'(3,-6)

Find the initial population size
Answers
The numeric values for the population function are given as follows:
Initial population: 49 individuals.Population after eight years: 292 individuals.How to find the numeric value of a function or of an expression?To obtain the numeric value of a function or of an expression, each instance of the input variable in the function or in the expression is replaced by the value at which we want to find the numeric value.
The function giving the population after t years is defined as follows:
[tex]P(t) = \frac{340}{1 + 6e^{-0.45t}}[/tex]
The initial population is the numeric value at t = 0, that is, the lone instance of t is replaced by zero, hence:
[tex]P(0) = \frac{340}{1 + 6e^{-0.45(0)}} = \frac{340}{7} = 49[/tex]
After eight years, the population is given by the numeric value at t = 8, hence:

A rectangle with dimensions 60 units * 40 units is drawn on a grid paper that has a 1 unit * 1 unit grid. Each vertex of the rectangle is on a node, and each side of the rectangle is on a gridline. Then a diagonal of the rectangle is drawn. How many cells are cut into two(not necessarily equal) parts? PLEASE ANSWER ASAP!!!!!!!
Answers
The number of cells cut into two by the diagonal of the rectangle, found by using Pythagorean theorem, are approximately 51 cells
What is Pythagorean theorem?Pythagorean theorem can be expressed as the square of the hypotenuse side of a right triangle is equal to the sum of the square of the legs of the triangle.
The dimensions of the rectangle = 60 units by 40 units
The dimensions of each grid = 1 unit by 1 unit
The vertices of the rectangle are (0, 0), (60, 0), (60, 40), (0, 40)
The slope of the diagonal is therefore;
m = 40/(60) = 2/3
The equation of the line is; y - 0 = 2/3·(x - 0) = 2/3·x
y = 2/3·x
The number of cells in the diagonal is found using Pythagorean theorem as follows as follows;
Length the diagonal, l = √(60² + 40²) ≈ 72.1
Length of the diagonal of a unit = √(1 + 1) =√2
Number of units in the diagonal, n = 72.1/√(2) ≈ 51 units
The number of cells cut into two ≈ 51 cells

Here is a correlation, does it also represent causation? Explain you answer.
The miles driven and the amount of gasoline used.
Answers
Yes the miles driven and the amount of gasoline used can be said to have a causation as well as a correlation.
What is causation in statistics?The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number. However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.
There is a causal relationship between the two occurrences, which means that causation shows that one event is the outcome of the occurrence of the other event. This concept is also known as cause and effect.
When the amount of gasoline is small, it would cause the miles covered to be just a few miles. Or if there is no gas, then no mile would be covered.

Answers
Considering the definition of an inequality, the maximum number of people who can go to the amusement park is 4.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that:
A group of friends have no more than $110 to spend on parking and admission. Parking is $10.50, and tickets cost $23.50 per person, including tax.Being "x" the maximum number of people who can go to the amusement park, the inequality that expresses the previous relationship is
10.50 + 23.50x ≤ 110
Solving:
23.50x ≤ 110 - 10.50
23.50x ≤ 99.50
x ≤ 99.50÷ 23.50
x ≤ 4.23

Answers
Option D is the right choice.
It is discovered through the use of conditional probability that there is a 0.4 = 40% chance that it will stop working in less than 2 years.
Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
Conditional Probability:
P (B / A) = P (A∩B) / P (A)
Here:
P(B / A) is the likelihood that event B will occur in the absence of event A.
P (A∩B) is the likelihood that both A and B will occur.
P(A) denotes the likelihood that A will occur.
As per the question:
Event A: Delivery was harmed.
Event B: Fails to function after less than two years.
P (A) = 0.1 due to the probability of being damaged during delivery being 0.1.
P (A∩B) = 0.04 because there is a 0.04 likelihood that it will be damaged during the delivery and stop working.
The likelihood under the condition is:
P (B / A) = P (A∩B) / P (A) = 0.04 / 0.1 = 0.4
0.4 = 40% chance that it will stop working in under two years.
Therefore, option D is correct.

We can figure this out by going down each option and checking if it works and is arranged from least to greatest.
The first option provides the numbers -3.5, -1/4, 2, 1/3 in that order.
This does not work because 1/3 is less than 1 which is less than 2. 1/3 should come before 2.
The second option provides the numbers -3.5, -1/4, 1/3, 2.
This option does work, because -3.5 is less than -1/4, -1/4 is less than 1/3 because it is negative, and 1/3 is less than 2.
If we look at this on a number line, the numbers that are smaller will appear farther to the left on the number line.
A fence is to be built to enclose a rectangular area of square feet. The fence along three sides is to be made of material that costs $ per foot. The material for the fourth side costs $ per foot. Find the dimensions of the rectangle that will allow for the most economical fence to be built.
Answers
The dimensions of the rectangle that will allow for the most economical fence to be built is 50 feet and 25 feet in length and width respectively.
Given in the question,
Area = 1250 ft²
The three sides cost $3 per foot, and the fourth side costs $9 per foot.
Let x and y be the length and width of the rectangle.
Because the area is 1250 ft², therefore
xy = 1250, or
y = 1250/x
Case 1: Three sides are (x,y,x) and the 4-th side is y.
The cost is
C = 3(2x +y) + 9y
= 6x + 12y
= 6x + 12(1250/x)
= 6x + 15000/x
For C to be minimum, C' = 0. That is
6 - 15000/x² = 0
x² = 15000/6
x = 50 ft, y = 1250/50 = 25 ft
C = 6(50) + 15000/(50²) = $600
Case 2: Three sides are (y,x,y) and the 4-th side is x.
The cost is
C = 3(x + 2y) + 9x
= 12x + 6y
= 12x + 6(1250/x)
= 12x + 7500/x
For C to be minimum, C' = 0.
12 - 7500/x² = 0
x² = 7500/12 = 625
x = 25 ft, y = 50ft
C = 12(25) + 7500/25 = $600
Thus, the Dimensions will be 25 feet and 50 feet.

. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answers
The correct selling price of the item has being solved as $20.04 The error that the manager has made is $12.04
How to solve for the markupGiven that there is a markup, the item that is being sold for 12 dollars would be affected by the percentage of the mark up.
This mark up is a 67% markup
This would be solved as
12$ + 67% of 12$
= $12 + 8.04
= $20.04
Hence the correct selling price is $20.04
Next we would have to find the likely error that the manager has made
= $20.04- $8
= $12.04

Using the exterior angles theorem, the measures of the named angles are:
m∠PQR = 51°
m∠PRQ = 96°
What is the Exterior Angles Theorem?Based on the exterior angles theorem, the measure of the exterior angle of a triangle has an angle degree that is equal to sum of the interior angles of the triangle.
Therefore, the following equation would be set to find the value of x:
33 + 10x + 1 = 17x - 1
34 + 10x = 17x - 1
Combine like terms
34 + 1 = 17x - 10x
35 = 7x
35/7 = 7x/7
5 = x
x = 5
m∠PQR = 10x + 1 = 10(5) + 1 = 51°
m∠PRQ = 180 - (17x - 1) = 180 - (17(5) - 1) = 96°

(round your answer to four decimal places.)
Answers
The Probability that someone holds b.s. degree if it is known that he or she earns more than $100,000 is 0.75.
Considering the values given in the question,
P(earns more than $100000 without college education) = 0.2
P(earns more than $100000 with a B.S. or higher degree) = 0.6
P(Has a B.S. degree) = 0.5
P(earns more than $100000) = P(earns more than $100000 | without college education) × P(without college education) + P(earns more than $100000 | with a B.S. or higher degree) × P(has a B.S. degree)
= 0.2 × (1 - 0.5) + 0.6 × 0.5
= 0.4
P(at least a B.S. degree | earns more than $100,000) = P(earns more than $100000 | with a B.S. or higher degree) × P(has a B.S. degree) / P(earns more than $100000)
= 0.6 × 0.5 / 0.4
