The probability of picking a green jelly bean with the first pick is 4/14 = 2/7, because there are 14 jelly bean in total (6 red + 4 green + 4 blue) and 4 of them are green.
If you pick a green jelly bean at the beginning, you have 13 jelly beans remaining, of which 6 are red. So, the probability of picking a red jelly bean is now 6/13.
You want these two events to happen one after the other, to be more precise you want to pick a green jelly bean with the first pick AND a red jelly bean with the second pick. We know the probabilities of the two events, so we have to multiply them to get the probability of them happening both:
[tex]\dfrac{2}{7}\cdot\dfrac{6}{13}=\dfrac{12}{91}[/tex]

Do you think that a 270° clockwise rotation is the same as a 90° counterclockwise rotation? Explain why or why not.
Answer: This would equal the same distance
Explanation: Think of a clock if it rotates 90 degrees counter clockwise it would stop at the number 9. If it rotates 90 clockwise it would stop at 3, then rotate that hand clockwise by 90 degrees one more time it will stop at 6, then 9 at 270 degrees.
Answer:
sorry if im late but this is the answer:
Step-by-step explanation:
Yes, I think they are the same. One revolution is 360 degrees. A 180-degree clockwise rotation is the same as a 180-degree counterclockwise rotation. The sum of the measures is 360. So, moving in a clockwise direction for 270 degrees would end at the same place as moving 90 degrees in a counterclockwise direction.

Kelly paid $54.60 for a bike helmet that was 20% off the original price. What was the original price
The original price of the bike helmet was $68.25, calculated by understanding that the $54.60 Kelly paid represented 80% of the original price after a 20% discount.
Explanation:Kelly paid $54.60 for a bike helmet that was 20% off the original price. To find the original price of the helmet, we need to understand that the price Kelly paid is 80% of the original price, after the discount was applied. Therefore, the equation to find the original price (OP) is:
54.60 = 0.80 × OP
To solve for OP, we divide both sides of the equation by 0.80:
OP = 54.60 / 0.80
OP = $68.25
Thus, the original price of the bike helmet was $68.25.

El área de una propiedad en metros cuadrados, mide 704/5. Se construye una casa que ocupa 5/6 del área total. La mitad del área restante se utiliza para construir una terraza, cuanta área falta por construir?
Answer:
The area left to build is [tex]\frac{704}{60}\ m^{2}[/tex]
Step-by-step explanation:
The question in English is
The area of a property in square meters, measures 704/5. A house is built that occupies 5/6 of the total area. Half of the remaining area is used to build a terrace, how much area is left to build?
we know that
The total area represent the fraction 6/6
A house represent the fraction 5/6 of the total area
The remaining area represent the fraction (6/6)-(5/6)=1/6 of the total area
If half of the remaining area is used to build a terrace
then
the area of the terrace represent the fraction (1/6)/2=1/12 of the total area
therefore
The area left to build represent the fraction 1/12 of the total area
so
[tex](\frac{1}{12})\frac{704}{5} =\frac{704}{60}\ m^{2}[/tex]

Answer:
c. 105 yd^2.
Step-by-step explanation:
First find the slant height (h) of each of the triangular walls:
tan 60 = h / 3.1
h = 3.1 tan 60
= 5.369 yds.
Area of each side = 3.1* 5.369

Liam is a tyre fitter it takes him 56 minutes to fit 4 tyres to a van how long would it take to fit 12 tyres to 3 vans
Answer:
168 minutes, or 2 hours, 48 minutes
Step-by-step explanation:
Set up a proportion and solve.
56 minutes is to 4 tires as 'x' minutes are to 12 tires
becomes
56/4 = x/12 solve for x...
[56(12)]/4 = x (multiply both sides by 12 to get rid of the fraction)
672/4 = x (simplify 52(12) = 672)
168 = x (simplify 672/4 = 168)
Identify the graph of 9X^2+4xy+5y^2-40=0 and find theta to the nearest degree.
Answer:
The answer is ellipse; 23° to the nearest degree ⇒ answer (d)
Step-by-step explanation:
* At first lets talk about the general form of the conic equation
- Ax² + Bxy + Cy² + Dx + Ey + F = 0
∵ B² - 4AC < 0 , if a conic exists, it will be either a circle or an ellipse.
∵ B² - 4AC = 0 , if a conic exists, it will be a parabola.
∵ B² - 4AC > 0 , if a conic exists, it will be a hyperbola.
* Now we will study our equation:
- 9x² + 4xy + 5y² - 40 = 0
∵ A = 9 , B = 4 , 5 = 5
∴ B² - 4 AC = (4)² - 4(9)(5) = -164 < 0
∴ B² - 4AC < 0
∴ If a conic exists, it will be either a circle or an ellipse.
* To find the type of the graph lets check;
- If A and C are nonzero, have the same sign, and are not
equal to each other, then the graph is an ellipse.
- If A and C are equal and nonzero and have the same
sign, then the graph is a circle.
∵ A and C have same signs and are not equal
∴ The graph is an ellipse
* If we have term xy ⇒ B ≠ 0
∴ The graph is rotate by angle Ф
* To find the angle of rotation use the rule:
- cot(2Ф) = (A - C)/B
∵ A = 9 , B = 4 , C = 5
∴ cot(2Ф) = (9 - 5)/4 = 4/4 = 1
∴ tan(2Ф) = 1
∴ 2Ф = 45°
∴ Ф = 22.5° ≅ 23° to the nearest degree
* The answer is ellipse; with angle of rotation = 23°
Identify the equation of the translated graph in general form x^2-y^2=8 for T(4,3)
Answer:
B
Step-by-step explanation:
A transformation of T(a,b) in the equation would give this form:
[tex](x-a)^2+(y-b)^2=8[/tex]
So, T(4,3) means translation of 4 units in x and 3 units in y. Thus, we can write:
[tex](x-4)^2+(y-3)^2=8[/tex]
Expanding and rearranging, we get:
[tex](x-4)^2-(y-3)^2-8=0\\x^2-8y+16-y^2+6y-9-8=0\\x^2-y^2-8x+6y-1=0[/tex]
Answer choice B is right.

Alex doesn't remember what the Zero Product Property is used for. Explain to Alex what the property is and how it is used.
The Zero Product Property in mathematics states that if the product of two numbers is zero, then at least one of the numbers must be zero. You typically use this property when solving quadratic equations by setting each factored term equal to zero and then solving for every variable.
Explanation:The Zero Product Property is an essential concept in algebra, particularly when it comes to solving quadratic equations. The Zero Product Property states that if the product of two numbers, terms, or factors is zero, then at least one of the factors must be zero. In simple terms, if a * b = 0, then a has to be zero, or b has to be zero, or both.
To use the Zero Product Property, you usually start by setting an equation equal to zero. For example, let's solve the quadratic equation x^2 - 5x = 0. First, you would factor the equation to (x)(x-5) = 0. Now, using the Zero Product Property, we can set each factor equal to zero and solve for x. This gives us x = 0 and x = 5.
