Answer:
y = 0, 3
Step-by-step explanation:
1) Add 1 to both sides.
4 ∣ 2y −3 ∣ = 11 + 1
2) Simplify 11+1 to 12.
4 ∣ 2y − 3∣ = 12
3) Divide both sides by 4.
∣ 2y − 3∣ = 12 / 4
4) Simplify 12/4 to 3.
∣ 2y − 3 ∣ = 3
5) Break down the problem into these 2 equations.
2y − 3 = 3
-(2y - 3 ) - 3
6) Solve the 1st equation: 2y − 3 = 3
y = 3
7) Solve the 2nd equation: -(2y - 3 ) - 3
y = 0
8) Collect all solutions.
y = 0, 3
What is the probability that a registered voter voted in the election?
Answer:
0.4714
Step-by-step explanation:
The diagram shows:
3,371,556 registered voters which did not vote;3,006,202 registered voters which voted in the election.Then the total number of registered voters is
[tex]3,371,556+3,006,202=6,377,758[/tex]
Thus, the probability that a registered voter voted in the election is
[tex]\dfrac{3,006,202}{6,377,758}\approx 0.4714[/tex]
The probability that a registered voter participated in the election can vary significantly. In the U.S. 2020 Presidential Election, 77 percent of registered voters voted. However, it's vital to consider the full context, including the total and voting-age populations, and understand that turnout rates can vary by factors like age.
Explanation:The probability that a registered voter voted in the election depends on various factors such as the year, voters' ages and other socioeconomic factors. In the U.S., for instance, in the 2020 Presidential Election, 77 percent of registered voters cast their vote. However, it's vital to keep in mind that while this data is significant, it doesn't give full context without considering factors such as the eligible voting-age population or the total population.
Furthermore, it's useful to understand the concept of a 90 percent confidence level when interpreting statistics related to voter turnout. In this context, the statement 'We estimate with 90 percent confidence that between 56.4 percent and 63.6 percent of all students are registered voters.' suggests that there's a 90 percent probability that the actual percentage of registered voters among all students falls between the specified range.
On a related note, the age group also influences voter turnout. For instance, in 2016, 51 percent of eligible voters between the ages of eighteen and twenty-four registered, but only 39 percent of them voted. Conversely, 75 percent of eligible voters aged from sixty-five to seventy-four registered, and of these, 68 percent voted. Hence, the probability of a registered voter voting in the election can vary quite a bit based on age, among other factors.

There are 20 cars in my building's parking lot. All of the cars are red or white. Also, all the cars are either 2-door or 4-door. 12 of them are red, 15 of them are 4-door, and 4 of them are 2-door and white. How many of the cars are 4-door and red?
Answer:
11 cars
Step-by-step explanation:
There are 20 cars in my building's parking lot, 15 cars are 4-door, then
[tex]20-15=5[/tex] cars are 2-door.
5 cars are 2-door, 4 of them are 2-door and white, then
[tex]5-4=1[/tex] car is 2-door and red.
12 cars are red, 1 car is 2-door and red, then
[tex]12-1=11[/tex] cars are 4-door and red.
(1/3) are red = 30 *1/3 = 10 are red
So...20 are white
50% are 4 door = 15 are 4 door
So....15 are 2 door
8 are 2 door and white.....so 12 are 4 door and white since we have 20 white total
And since 15 are 4 door and 12 of these are white...then 3 must be 4 door and red
ORRRRMake a two-way table as follows:
RED WHITE
2-DOOR 7 8
4-DOOR 3 12
TOTALS 10 20
So, it looks like you have 3 cars that are red and have 4 doors.

The force F needed to stop a car varies directly as its weight W and the square root of velocity V are inversely as the distance d travelled. When F=36 Newtons, W=120kg,V=100km/h and d=50km. Calculate the force required for V=256km/h,W=200kg and d =800km. This is the question pls answer it dont by pass it pls
Final answer:
To calculate the force required, we use the formula F = k * (W / sqrt(V)) * (1 / d), where F is the force, W is the weight, V is the velocity, and d is the distance. We can find the constant of variation k by substituting the given values of F, W, V, and d into the formula. After finding k, we can plug in the new values of W, V, and d to calculate the force required.
Explanation:
To solve this problem, we can use the formula F = k * (W / sqrt(V)) * (1 / d), where F is the force, W is the weight, V is the velocity, and d is the distance.
First, we can calculate the constant of variation k by substituting the given values of F, W, V, and d into the formula. This gives us: 36 = k * (120 / sqrt(100)) * (1 / 50).
Solving for k, we get k = 36 * 100 * 50 / 120 = 1500.
Next, we can plug in the new values of W, V, and d into the formula and solve for F. Substituting W = 200, V = 256, and d = 800, we have: F = 1500 * (200 / sqrt(256)) * (1 / 800).
Simplifying further, we get F = 1500 * 200 / (16 * 800) = 18.75 Newtons.

How can you express 5 1/3 + (-7 2/3) as the sum of its integer and fractional parts
Answer:
-7/3
Step-by-step explanation:
-7 2/3=-23/3
5 1/3=16/3
-----------------
16/3+(-23/3)
16/3-23/3
-7/3
Final answer:
To express 5 1/3 plus (-7 2/3), separate and add the integers to get -2, then add the fractions to find -1/3, resulting in the final expression -2 1/3.
Explanation:
To express the sum of 5 1/3 and (-7 2/3) as the sum of its integer and fractional parts, we need to perform the following steps:
First, separate the integers from the fractions: 5 + 1/3 and -7 + (-2/3).Now, add the integers: 5 + -7 = -2.Next, add the fractions: 1/3 + (-2/3). Recall that subtracting a negative is the same as adding a positive, so this becomes 1/3 - 2/3 = -1/3.Combine the integer and fractional results to get the final expression: -2 1/3.Our intuition about addition and subtraction of fractions can be helpful in visualizing the mixing of different pie pieces to form a whole, and understanding how changing the sign affects the direction of the operation.

The solutions for x are -2, 0, 2
Solution:
Given that,

pls answer ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
[tex]A'(-0.25,0.75)\\\\B'(1.75,-0.25)\\\\C'(-1,-0.25)[/tex]
Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case you know that the triangle ABC was dilated by this scale factor:
[tex]scale\ factor=\frac{1}{4}[/tex]
With the origin as the center of dilation.
Since:
[tex]0<\frac{1}{4}<1[/tex]
It is a Reduction.
You can identify that the vertices of the triangle ABC are:
[tex]A(-1,3)\\\\B(7,-1)\\\\C(-4,-1)[/tex]
So you need to multiply the coordinates of each vertex of the triangle ABC by [tex]\frac{1}{4}[/tex], in order to get the coordinates of the triangle A'B'C. Then, you get:
[tex]A'=(\frac{1}{4}(-1),\frac{1}{4}(3))=(-0.25,0.75)\\\\B'(\frac{1}{4}(7),\frac{1}{4}(-1))=(1.75,-0.25)\\\\C'(\frac{1}{4}(-4),\frac{1}{4}(-1))=(-1,-0.25)[/tex]
The coordinates of the vertices of triangle A'B'C' include the following;
A' (-1/4, 3/4).
B' (7/4, -1/4).
C' (-1, -1/4).
What is dilation?In Mathematics and Euclidean Geometry, dilation is a type of transformation that is used for altering the dimensions of a geometric figure, but not its shape.
In this scenario and exercise, we would have to dilate the coordinates of the pre-image by using a scale factor of 1/4 centered at the origin as follows:
Ordered pair A (-1, 3) → (-1 × 1/4, 3 × 1/4) = Ordered pair A' (-1/4, 3/4).
Ordered pair B (7, -1) → (7 × 1/4, -1 × 1/4) = Ordered pair B' (7/4, -1/4).
Ordered pair C (-4, -1) → (-4 × 1/4, -1 × 1/4) = Ordered pair C' (-1, -1/4).

Which shows a difference of squares? 10 y squared minus 4 x squared 16 y squared minus x squared 8 x squared minus 40 x + 25 64 x squared minus 48 x + 9
Answer:
16y² - x² shows a correct difference of squares.
Step-by-step explanation:
Following are the given options from which we have to chose which represents the difference of squares.
A) 10y² - 4x²
B) 16y² - x²
C) 8x² - 40x+25
D) 64x² - 48x+9
Difference of square is given by:
a² - b² = (a + b) (a - b)
If we analyze the expressions from the choices given in the question. We should figure out that option B) should be the right answer that shows a difference of squares. i.e. 16y² - x² shows a correct difference of squares. All other options do not represent the difference of perfect squares.
As in option A) 10y² - 4x²
10y² is not a complete square of any number. Hence, option A) is incorrect.
As in option C) 8x² - 40x+25
Neither of the terms in the expression as shown in option C can be a perfect square. Hence, option C) is incorrect.
As in option D) 64x² - 48x+9
The term 48x+9 in the expression as shown in option D can not be a perfect square. Hence, option D) is incorrect.
Lets take the expression 16y² - x² of option B) and solve it.
First simplify the terms separately to associate them as perfect squares as shown below:
⇒ 16y² = (4y)² Equation (1)
⇒ x² = (1x)² Equation (2)
Now, take the difference of Equation (1) and Equation (2).
⇒ 16y² - x²
⇒ (4y)² - (1x)² Equation (3)
So,
Equation (3 )shows a difference of squares. It can also be represented as factorizing the difference of two perfect squares such as (4y - x) (4y + x).
Which is
(4y - x) (4y + x) = 16y² - x²
= (4y)² - (1x)²
So, option B) i.e. 16y² - x² shows a correct difference of squares.

Solve the system of equations by substitution
substitute equation A in equation B
[tex]0.25x+0.10(8-x)=1.70[/tex]
solve for x
[tex]0.25x+0.80-0.10x=1.70[/tex]
[tex]0.25x-0.10x=1.70-0.80[/tex]
[tex]0.15x=0.90[/tex]
[tex]x=6[/tex]
Find the value of y
[tex]y=8-x[/tex] ----> [tex]y=8-6=2[/tex]
therefore
Karen has 6 quarters and 2 dimes

In addition, her benefits include health insurance, paid holidays, retirement contributions, and a 2-week paid vacation, as well as saving $2,500 on clothing costs. Let's calculate the value of these benefits:
Health insurance: This benefit is not given a specific value, so we will assume a typical cost of $5,000 per year. (Note: This is an assumption and may vary depending on the specific circumstances).Paid holidays: Assuming 10 paid holidays per year, at an average daily rate of $100, the value of this benefit is $1,000.Retirement contributions: Assuming a 5% contribution from Michelle's salary, the value of this benefit is $1,600.2-week paid vacation: Assuming Michelle's base salary is $32,000 per year, the value of a 2-week paid vacation is $1,230 (($32,000/52)*2).Savings on clothing costs: As given, Michelle saves $2,500 on clothing costs per year.Now let's add up the base salary and the value of the benefits:
Base salary: $32,000
Health insurance: $5,000
Paid holidays: $1,000
Retirement contributions: $1,600
2-week paid vacation: $1,230
Savings on clothing costs: $2,500

Answer:
The length of A'C' will also be 5 units.
Step-by-step explanation:
If a reflection takes triangle CAT to C'A'T', what is A'C'?
Starting with ΔCAT triangle as shown in figure (a).
Reflections are said to be Isometries as it does preserve the distances.
If the shape or triangle ΔCAT reflected it will remain the same size. As a result, the reflected image would be 'congruent' to the original object.
Lets suppose, ΔCAT is reflected across y axis.
The rule for reflection of the point (x,y) across the y-axis is actually the point (-x,y).
Reflect a point across the y-axis, the y-coordinate will remain the same, but the x-coordinate will be transformed into its opposite (the sign of x-coordinate will be changed).
C(0, 0) → C'(0, 0)
A(-2, 1) → A'(2, 1)
T(-1, 4) → T(1, 4)
length of Side AT = 3 units
length of Side TC = 4 units
length of Side AC = 5 units
As reflections are said to be Isometries as it does preserve the distances.
So, if ΔCAT reflected is reflected across y axis. ΔC'A'T' preserves the distances. The length of each segment of the preimage would be equal to its corresponding side in the image as shown in figure (a).
So, the length of A'C' will also be 5 units.

The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below.
Write the formula to calculate the height, h.
The formula to calculate the height (h) of a cone, given its volume (V) and radius (r), is [tex]\(h = \frac{3V}{\pi r^2}\)[/tex]. This formula isolates the height by multiplying both sides of the volume formula by [tex]\(3/\pi r^2\).[/tex]
To isolate the height (h) in the volume formula of a cone ([tex]\(V = \frac{1}{3}\pi r^2 h\)[/tex]), we can rearrange the formula to solve for h.
Starting with the given formula:
[tex]\[ V = \frac{1}{3}\pi r^2 h \][/tex]
To find h, we can multiply both sides of the equation by [tex]\(3/\pi r^2\)[/tex] to isolate h:
[tex]\[ h = \frac{3V}{\pi r^2} \][/tex]
Therefore, the formula to calculate the height (h) of a cone, given its volume (V), radius (r), is:
[tex]\[ h = \frac{3V}{\pi r^2} \][/tex]
This formula allows you to determine the height of a cone when you know its volume and radius.
Jim went to a carnival with $25.00. He bought some food for $3.75. Jim wants to spend the rest of his money on tickets for rides, r, which cost $1.25 each. Which represents, r, the number of tickets Jim can purchase?
(A) r is < than equal to 17
(B) r is > greater than equal to 17
(C) r is < less than equal to 20
(D) r is > greater than equal to 20
Answer:
(A) [tex]r[/tex] is < than equal to 17
Step-by-step explanation:
Total amount Jim had for the carnival =$25.00
Amount spent on food = $3.75
Amount left with him = [tex]\$25.00-\$3.75=\$21.25[/tex]
Jim plans to sped rest on tickets for rides.
Cost of each ride ticket = $1.25
Given: [tex]r[/tex] represents the number of ride tickets bought.
Using unitary method
If 1 ride ticket cost = $1.25
Cost of [tex]r[/tex] ride tickets in dollars will be = [tex]1.25r[/tex]
Amount spent on rides must be less than or equal to the total amount left with Jim which is =$21.25.
So, we have:
⇒ [tex]1.25r\leq 21.25[/tex]
Dividing both sides by 1.25.
⇒ [tex]\frac{1.25r}{1.25}\leq \frac{21.25}{1.25}[/tex]
∴ [tex]r\leq 17[/tex]
Thus, the inequality representing te number of tickets Jim can purchase is given by:
[tex]r\leq 17[/tex]

- The perimeter (P) of a rectangle is the total distance around its boundary, which is calculated by adding together twice the length (L) and twice the width (W): `P = 2L + 2W`.
- We have two pieces of information to work with:
1. The length is 6 yards longer than the width, which we can express as `L = W + 6`.
2. The perimeter is 72 yards, so `P = 72`.
With these equations, we can set up our system to solve for the length and width:
1. Substitute the expression for L from the first piece of information into the perimeter formula:
`P = 2(W + 6) + 2W`
2. Plug in the value for the perimeter:
`72 = 2(W + 6) + 2W`
3. Distribute the 2 through the parentheses:
`72 = 2W + 12 + 2W`
4. Combine the W terms:
`72 = 4W + 12`
5. Isolate the W term by subtracting 12 from each side:
`72 - 12 = 4W`
`60 = 4W`
6. Divide by 4 to solve for W:
`W = 60 / 4`
`W = 15`
Now that we have the width, we can use the first equation to solve for the length:
`L = W + 6`
`L = 15 + 6`
`L = 21`
So, the width (W) is 15 yards and the length (L) is 21 yards.
What is the reason for each step in the solution of the equation? 18x-2x=4x. Match the reasons with each step in the equation
The correct answer is:
The equation simplifies to [tex]\(x = 0\)[/tex] after combining like terms and isolating [tex](x\), resulting in \(x\)[/tex] being zero.
the equation [tex]\(18x - 2x = 4x\)[/tex] step by step:
1. Original equation:
[tex]\[ 18x - 2x = 4x \][/tex]
2. Combine like terms on the left side:
[tex]\[ 16x = 4x \][/tex]
Explanation: We add or subtract coefficients of like terms. Here,[tex]\(18x - 2x\) simplifies to \(16x\).[/tex]
3. Subtract [tex]\(4x\)[/tex] from both sides:
[tex]\[ 16x - 4x = 0 \][/tex]
Explanation: We want to isolate [tex]\(x\)[/tex] on one side. Subtracting [tex]\(4x\)[/tex] from both sides ensures the equation remains balanced.
4. Simplify:
[tex]\[ 12x = 0 \][/tex]
Explanation: After subtracting, we simplify the expression [tex]\(16x - 4x\) to \(12x\).[/tex]
5. Divide both sides by [tex]\(12\)[/tex]:
[tex]\[ \frac{12x}{12} = \frac{0}{12} \] \[ x = 0 \][/tex]
Explanation: To solve for [tex]\(x\), we divide both sides by the coefficient of \(x\), which is \(12\).[/tex]
Therefore, the solution to the equation [tex]\(18x - 2x = 4x\) is \(x = 0\)[/tex]. This means [tex]\(x\)[/tex] is zero, satisfying the equation.

Is -x+4y=-2 a direct variation?
Answer:
No
Step-by-step explanation:
Direct variation: two variables, one variable is a constant multiple of another variable
y = k x .... k constant
-x+4y=-2
4y = x - 2
y = 1/4 x -1/2 ..... y = k x + b y is not a simple multiple of x
Solve the equation.
9x + 33 = -30
Answer:
x=-7
Step-by-step explanation:
Subtract 33 from -30 (because subtraction is the opposite of addition.
that's leaves 9x=-63
you want to isolate the variable so divide -63 by 9 (since division is the opposite of multiplication)
x=-7
