Use the method of your choice to determine the probability below. Being dealt three threes off the top of a standard deck of well-shuffled cards. The probability is____
The probability of being dealt three threes off the top of a standard deck of well-shuffled cards can be calculated using the following method:
Method 1: The probability of drawing the first three from a deck of 52 cards is 4/52 or 1/13, since there are four threes in a deck of 52 cards.
The probability of drawing the second three is now 3/51, as there are only three threes left in the deck of 51 cards.The probability of drawing the third three is now 2/50, since there are only two threes left in the deck of 50 cards.
So, the probability of being dealt three threes off the top of a standard deck of well-shuffled cards is:
Probability = (1/13) × (3/51) × (2/50) = 6/132600 = 1/22100
Therefore, the probability of being dealt three threes off the top of a standard deck of well-shuffled cards is 1/22100.
Method 2: Another method to calculate the probability of being dealt three threes off the top of a standard deck of well-shuffled cards is using combinations. There are a total of 52C3 ways to draw three cards from a deck of 52 cards without replacement.
Out of these, there is only one combination that has three threes. Therefore, the probability of being dealt three threes off the top of a standard deck of well-shuffled cards is:
Probability = 1/52C3 = 1/22100
Hence, the probability of being dealt three threes off the top of a standard deck of well-shuffled cards is 1/22100.

14. Solve the following equations. Give your answers in the
interval 0º < x < 360°.
d) 1 + 3 sin x=0
Answer:
x ≈ 199.5°, x ≈ 340.5°
Step-by-step explanation:
Given
1 + 3sinx = 0 ( subtract 1 from both sides )
3sinx = - 1 ( divide both sides by 3 )
sinx = - [tex]\frac{1}{3}[/tex]
Since sinx < 0 then x is in the third/ fourth quadrants, thus
x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{3}[/tex] ) ≈ 19.5° ← related acute angle, then
x = 180° + 19.5° = 199.5°
x = 360° - 19.5° = 340.5°
Solution is x = 199.5°, x = 340.5° for 0° < x < 360°
A dumpster in the shape of a rectangular prism has a volume of 240 cubic feet. The length of the dumpster is 4 feet less than twice the width w, and the height is 1 foot less than the width.
Find the equation, in terms of w, that could be used to find the dimensions of the dumpster in feet. Your answer should be in the form of a polynomial equals a constant.
Answer:
Step-by-step explanation:
v=240
l= 2(w)-4
h=(w-1)
v= l*w*h
240=(2w-4)(w-1)w
we then foil
(2w^2 - 6w + 4) w
lastly multiply the w in
ANSWER: 2w^3 - 6w^2 + 4w = 240
Consider the following statement: If 4x = 8, then x = 2. What is the inverse of the statement? If 4x ≠ 8, then x ≠ 2. If x = 2, then 4x = 8. If 4x = 8, then x = 2. If x ≠ 2, then 4x ≠ 8.
Answer:
If x = 2, then 4x = 8
Step-by-step explanation:
In mathematics, an inverse function or statement can be described as a function or statement which reverses another function or statement.
In the question, we are given:
If 4x = 8, then x = 2
That is, x = 2 is obtained by solving fo x from 4x = 8 as follows:
4x = 8
x = 8 / 4
x = 2
From the options given, on the statement "if x = 2, then 4x = 8" reverses the statement "if 4x = 8, then x = 2". This is because x = 2 now comes first before 4x = 8 as against what obtained initially where 4x = 8 comes first before x = 2.
Therefore, the correct option is "If x = 2, then 4x = 8".
Answer:
So if x would equil 2, then (4x) = 8

Write a delta-epsilon proof that shows that the function f(x) = px , pER is continuous on its
domain.
The function f(x) = px, where p is a real number, is continuous on its domain by the definition of continuity, as for any ε > 0, there exists a δ > 0 such that |f(x) - f(a)| < ε whenever |x - a| < δ.
To prove that the function f(x) = px, where p is a real number, is continuous on its domain, we need to show that for any ε > 0, there exists a δ > 0 such that |f(x) - f(a)| < ε whenever |x - a| < δ.
Let's proceed with the delta-epsilon proof:
Given a value of ε > 0, we need to find a corresponding δ > 0. Let's choose δ = ε/|p|. Note that δ will be positive as ε and |p| are both positive.
Now, consider any two points x and a such that |x - a| < δ. We want to show that |f(x) - f(a)| < ε.
Using the definition of f(x) = px, we can calculate:
|f(x) - f(a)| = |px - pa| = |p(x - a)|
Since |x - a| < δ, we know that |x - a| < ε/|p|. Multiplying both sides by |p| gives:
|p(x - a)| < |p| * (ε/|p|)
The |p| terms cancel out:
|p(x - a)| < ε
Since ε > 0, |p(x - a)| < ε implies that |f(x) - f(a)| < ε.
Therefore, for any ε > 0, we have found a δ = ε/|p| such that |f(x) - f(a)| < ε whenever |x - a| < δ. This satisfies the definition of continuity.
Hence, we have proven that the function f(x) = px, where p is a real number, is continuous on its domain.

For the given quadratic we have:
Axis of symmetry: x = -2Vertex: (-2, -4)Y-intercept: y = 0Minimum: y = -4x-intercepts: x = -2 ± 2 Domain --> (-∞, ∞)Rrange --> [-4, ∞)How to describe the quadratic equation?We have a quadratic equation in vertex form, it is:
y = (x+2)²-4
We can see that the vertex is at (-2, -4)
Then tha axis of symmetry must be at the same x-value than the vertex, so it is at:
x = -2
Now, our quadratic equation has a positive leading coefficient, then in opens upwards, thus, we have a minimum at the vertex, and it is:
minimum: y = -4
y-intercept:
Here just evaluate in x = 0.
y = (0+2)²-4 = 0
The x-intercepts, we need to solve:
0 = (x + 2)² - 4
4 = (x + 2)²
±2 = x + 2
-2 ± 2 = x
These are the x-intercepts.
Finally, the domain is the set of all real numbers and the range is the set of all real numbers larger than the minimum, so:
D --> (-∞, ∞)
R --> [-4, ∞)

Write the coordinates of the vertices after a reflection over the line y=3?
The coordinates of the vertices after a reflection as follows:A → (2, 2)B → (5, 2)C → (4, 5).
Given that we are to reflect the coordinates of vertices over the line y = 3, we can conclude that the reflection will be on the x-axis.
Therefore, for a reflection in the line y = 3, the coordinates of the vertices after reflection are obtained by replacing y with 6 − y.
We are given the following triangle, therefore:
vertices coordinates for ABC: A(2, 4), B(5, 4) and C(4, 1)
For vertex A, its new coordinates after reflection will be (2, 2)
For vertex B, its new coordinates after reflection will be (5, 2)
For vertex C, its new coordinates after reflection will be (4, 5)
Hence, the coordinates of the vertices after a reflection over the line y = 3 are as follows:A → (2, 2)B → (5, 2)C → (4, 5).

Solve and find the value of X : a=0.697,b=0.6, (a)∧2=(b)∧2∗(x)∧2 [enter your answer with 3 decimals]
We are given the values of a and b and an equation involving exponents. We need to solve for the value of x.
The given equation is [tex](a)^2[/tex] =[tex](b)^2[/tex] * [tex](x)^2[/tex].
We can solve for x by isolating it on one side of the equation. Let's rewrite the equation: [tex](a)^2[/tex] = [tex](b)^2[/tex] * [tex](x)^2[/tex]
Taking the square root of both sides, we have: [tex]\sqrt{a^2}[/tex]= [tex]\sqrt{b^2}[/tex] * [tex](x)^2[/tex]
Simplifying further, we get: a = b * x
Now we can solve for x by dividing both sides of the equation by b: x = a / b.
Substituting the given values of a and b into the equation, we have: x = 0.697 / 0.6
Evaluating this expression, we find: x ≈ 1.162
