Calculate the perimeter of the parallelogram. Round to the nearest tenth, if necessary. Enter the perimeter, in units, using numbers only (decimal point is ok, if needed).
Answer:
28 units
Step-by-step explanation:
Firstly, we can see that the vertical sides are 9 units each.
To get the diagonal sides, we can turn the ends into right triangles, which we can then use with the Pythagorean Theorum.
To make the top side into a triangle, we would draw a horizontal line connecting points (-1, 3) and (3, 3). This creates a right angle which is essential when using the Pythagorean Theorum.
A^2 + B^2 = C^2
We can plug in values for the Pythagorean Theorum because we can see that going across horizontally from point (-1, 3) to (3, 3), there are 4 units in between the two points. This will be our A value. We will do the same but vertically from points (3, 6) to (3, 3). The 3 units between the two points will be our B value. Now, we can plug in our values into the Pythagorean Theorum to find side C, the hypotenuse.
4^2 + 3^2 = C^2
16 + 9 = C^2
25 = C^2
√25 = C
C = 5
Now that we know the diagonal value of the side, we also know the same diagonal value of the bottom side. When you add all four sides together,
9 + 5 + 9 + 5 = 28
you get 28, which is the perimeter of the parallelogram.

(Find the expected value of the winnings from a game that has the following payout probability)
I have all the answers with work shown and how to solve on the second image
Hope this help you guys :)
Answer:
The expected value is $2.1
Step-by-step explanation:
If we have an event with some given outcomes:
x₁, x₂, ..., xₙ
Such that each one of these outcomes has the correspondent probability:
p₁, p₂, ..., pₙ
The expected value is:
EV = p₁*x₁ + ... + pₙ*xₙ
In this case we have a table with the events (the payouts) and the probability for each one, so we have:
x₁ = $0
p₁ = 0.5
x₂ = $2
p₂ = 0.2
x₃ = $4
p₃ = 0.15
x₄ = $6
p₄ = 0.1
x₅ = $10
p₅ = 0.05
Now we can just replace these in the expected value equation, so we get:
EV = $0*0.5 + $2*0.2 + $4*0.15 + $6*0.1 + $10*0.05 = $2.1

Sabiendo que lo ancho de un terreno rectangular mide 24.7 m y que su perímetro es de 131.8 m. ¿Cuánto mide cada uno de sus lados largos?
Answer:
El perímetro de un terreno rectangular mide 48 m . Calcula sus dimensiones si el largo es el doble que el ancho.
Respuesta:
De largo mide 16m
De ancho mide 8m
Explicación paso a paso:
Perímetro = número de lados multiplicado por longitud del lado.
Formula: P = 2(a + b) o P = 2b + 2h
Donde: P = Rectángulo del perímetro
a y b = Longitudes de lados
Asignamos las variables:
Largo = 2x
Ancho = x
Utilizamos la formula:
2(x) + 2(2x) = 48
2x + 4x = 48
6x = 48
x = 48/6
x = 8m (ancho)
2x
2(8)
16m (largo)

If the solution to a linear system of equations is x=6 and y= 2 and you graphed the two equations, where would the two lines intersect? How do you know?
Answer:
(6,2)
Step-by-step explanation:
Combine them
Answer:
Step-by-step explanation:
A system of equations is a set of two or more equations that represent a relationship between two or more variables. A solution of this system is an ordered pair that satisfies each equation in the system. Finding the set of all solutions is called solving the system of equations. Solving a system of equations by graphing is exactly what the name implies – graph both equations, and their point(s) of intersection is the solution. A system of linear equations only have one solution because each equation is a straight line, they will only have one point of intersection (unless, of course, they are the same line).
THE TWO LINES WOULD INTERSECT (6, 2). BECAUSE THE SOLUTION IS THE INTERSECTION..
The right triangle represents a sketch of a wheelchair ramp that meets safety requirements. What is the horizontal distance required for the ramp? Round your answer the nearest tenth
The horizontal distance required for the ramp is 143.5 inches
Consider the following figure.
In right triangle ACB, CB is the horizontal distance,
hypotenuse AB = 144 in.
and the vertical distance AC = 12 in.
We need to find the measure of side CB
Let m be the measure of the horizontal distance CB
Using Pythagoras theorem for right triangle ACB,
(AB)² = (AC)² + (CB)²
Substitute given values in above equation.
(144)² = (12)² + (m)²
20736 = 144 + m^2
20736 - 144 = 144 + m^2 - 144
20592 = m^2
m^2 = 20592
m = 143.5 in.
Therefore, the horizontal distance is 143.5 in.

Which statement regarding the region of rejection for a 5%
significance level is TRUE?
A z-score higher than 2 is part of the region of rejection
The region of rejection lies between the z-scores -2 and
2.
If a z-score falls within the region of rejection, it indicates
that the alternative hypothesis may be valid.
The region of rejection indicates that the null hypothesis
is true.
The statement regarding the region of rejection for a 5% significance level would be true is the region of rejection lies between the z-scores -2 and 2.Option B is correct.
What is region of rejection?A collection of values for the test statistic for which the null hypothesis is rejected constitutes a critical zone, sometimes referred to as the region of rejection. For example, if the observed test statistic is in the critical range, the null hypothesis is rejected and the alternative hypothesis is accepted.
Further the rejection zone is the area in which we have sufficient data to reject the null hypothesis if our test statistic falls within it. The rejection area, for the right-tailed test, for instance, is any value bigger than the critical value, or c 1 .
Therefore, the interval that causes the null hypothesis H 0 to be rejected in a hypothesis test is known as the region of rejection and is measured in the sampling distribution of the statistic under examination.

Answer:
X=8
Step-by-step explanation:
Combine like terms: 5x + 2x = 7x
-15 + 7x = 41
Solving
-15 + 7x = 41
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7x = 41 + 15
Combine like terms: -15 + 15 = 0

You and 3 friends go out for lunch and the total bill was $36. You decide to split the bill evenly. You also decide to leave a 12% tip on your part. How much are you responsible for paying?
When you and your 3 friends decide to split the bill of $36 evenly and you leaving a 12% tip on your part, you pay a total of $13.32.
Therefore the answer is 13.32 dollars.
When you and your 3 friends decide to split the bill evenly, each person is responsible for paying 1/4 of the total bill. The total bill is $36, so each person is responsible for paying
$36 / 4 = $9
You also decided to leave a 12% tip on your part, so you need to calculate 12% of $36. To do this, you can multiply $9 by 0.12
$36 × 0.12 = $4.32
So, you are responsible for paying $9 + $4.32 = $13.32
So you are responsible for paying $13.32 in total.

VW = 9 ft
Step-by-step explanation:
Since the tangent lines connect both circles, we know that the line VU and VX are congruent (equal). Thus, we can set them equal to each other and solve for a:
a + 4 = a² + 0.25 Set equal
a² - a = 3.75 Isolate a values
a² - a + 0.25 = 3.75 + 0.25 Complete the square
(a + 0.5)² = 4 Factor
a + 0.5 = 2 Simplify
a = 1.5
Now we need to calculate VW, but thats easy because its equal to TV, and since we know a, we can just plug it in:
((1.5) + 7.5) ft
