jar a has exactly four red buttons and eight blue buttons. carla then removes the same number of red buttons as blue buttons from jar a and places them in an empty jar b. jar a now has $\frac{2}{3}$ of its original number of buttons. if carla were now to randomly choose a button from jar a and a button from jar b, what is the probability that the two chosen buttons will both be red? express your answer as a common fraction.
Answers
Probability of choosing two buttons each from the Jar a and Jar b is equal to ( 3/ 4).
As given in the question,
Number of red buttons in Jar a = 4
Number of blue buttons in Jar a = 8
Total buttons in Jar a = 12
After removing equal number of red and blue buttons from Jar a
Number of buttons left in Jar a = ( 2/ 3) × 12
= 8 buttons
total number of buttons in Jar b = 4
Both the buttons are equal
Number of red buttons in Jar b = 2
Number of blue buttons in Jar b = 2
Probability of choosing a red button from each Jar
= (²C₁ / ⁸C₁) + ( ²C₁ / ⁴C₁ )
= ( 2 / 8) + ( 2 / 4)
= ( 1/ 4) + ( 1/ 2)
= 3 / 4
Therefore, the probability of getting total two red buttons one from each Jar is equal to ( 3 /4).

Alvin can jog 9 km in 0. 75 hr. And bicycle 12 km in 0. 5 hr. What is p? select the hint button to view a hint.
Answers
The value of p is 2 , when Alan’s jogging speed is 0.02% of his cycling speed.
Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
According to the question,
Alvin can jog 9 kilometers in 0.75 hours, and he can cycle 12 kilometers in 0.5 hour.
Let the jogging speed be "x" and cycling speed be "y"
=> Average Speed = distance/time
jogging Speed : x = 9 kilometers / 0.75 hours
=> x = 9/0.75
=> x = 12
Therefore, Jogging speed = 12 kilometers per hour
Now,
Cycling speed : y = 12 kilometers / 0.5 hour
=> y = 24 kilometers per hour
Let " p" be the percent
=> 12p = 24
=> p = 24/12
Apply the division operation,
=> p = 2
Convert 2 to a percent.
x = 0.02%
Therefore, Alan’s running speed is 0.02% of his cycling speed.

What is the solution to the equation 5 (x minus 6) = 2 (x 3)? x =
Answers
the solution to the equation is x=12
The distributive property is defined as
Let us now solve the equation.
5(x - 6) = 2(x + 3)
Using the distributive property, simplify the parentheses on both sides.
5(x - 6) = 2(x + 3)
5x - 30 = 2x + 6
The parenthesis was simplified. However, we have one x term on one side and another x term on the other.
5x - 30 - 2x = 2x + 6 - 2x
3x - 30 = 6
We only have an x term on one side of the equation now.
To begin, reverse the subtraction by adding 30 to either side of the equation.
To keep an equation balanced or true, we do the identical operation on both sides.
3x - 30 + 30 = 6 + 30
3x = 36
We're getting close to an answer. Only one more step.
The x term is multiplied by 3.
We can undo the multiplication operation by dividing both sides by 3.
3x / 3 = 36 / 3
x = 12
So, x is equal to 12.

What is the vertex of a curve?The vertex of a parabola is a point at which the parabola makes its sharpest turn. A parabolic function has either a maximum value (if it is of the shape '∩') or a minimum value (if it is of the shape 'U"). The vertex of a parabola is also the point of intersection of the parabola and its axis of symmetry.
y = x^2 + 10x +15
making x^2 + 10x +15 a perfect square expression we square the half of the coefficient of x on both sides which is (5)^2
y + (5)^2 = x^2 + 10x + (5)^2 + 15
y + 25 = x^2 + 10x + (5)^2 + 15
x^2 + 10x + (5)^2 can be written as (x+5)^2 since iti is now a perfect square expression
y + 25 = (x+5)^2 + 15
y = (x+5)^2 + 15 - 25
y = (x+5)^2 -10
Equation of parabola in vertex form is y = a (x - h)2 + k
where k is the minimum or maximum point of vertex and h is the x coordinate of vertex.
comparing both equations, the coordinate of vertex (h, k) is (-5, -10) which is a minimum point.

Answers
The rule of reflection for the triangle △JKL to △J'K'L' is x = -4.
What is a triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
Given that the vertices of △JKL are J(1, 0), K(-5, 2), L(4, -4).
The vertices of △J'K'L' are J'(-9, 0), K'(-3, 2), L'(-12, -4).
The formula of midpoint of (x₁, y₁) and (x₂, y₂) is
((x₁+x₂)/2, (y₁+y₂)/2)
The midpoint of J(1, 0) and J'(-9, 0) is ((1+(-9)/2,(0+0)/2) = (-8/2,0) = (-4,0)
The midpoint of K(-5, 2) and K'(-3, 2) is ((-5+(-3)/2,(2+2)/2) = (-8/2,4/2) = (-4,2)
The midpoint of L(4, -4) and L'(-12, -4) is ((4+(-12)/2,(-4+(-4))/2) = (-8/2,-8/2) = (-4,-4)
Thus the x-coordinate of the midpoint is the same.
Thus the line of reflection is x = -4.

The length is 16 yards greater than 3 times x

f(x) = (3x+16)(x) = 3x^2 + 16x
Answer:
f(x) = 3x² + 16xStep-by-step explanation:
We have been given that -- The length of a rectangular parking lot is 16 yards greater than 3 times its width, x, in yards
Length of parking lot is 16 + 3x
Width of parking lot is x
We have to write the function f(x) that describes the area, in square yards, as a function of the width, x
Area of rectangle is Length × width
[tex] \sf Area = f(x) [/tex]
put value of length and width here,
[tex] \sf f(x) = (16 + 3x)(x )[/tex]
[tex] \sf f(x) = 3x^2 + 16x [/tex]
Therefore, f(x) = 3x² + 16x

If Jesus borrowed $1,000 for 1 week at an APR of 350%, the interest he has to pay at the end of the week is B. $67.31.
What is the interest?The interest represents the cost of borrowing.
The interest is computed as the principal multiplied by the annual percentage rate (APR) and time (period).
The interest formula used here is the simple interest instead of the compound interest, which charges interest on accumulated interest and the principal every period.
Principal borrowed for 1 week = $1,000
Annual percentage rate (APR) = 350%
Loan period = 1 week
52 weeks = 1 year
Interest = Principal x APR x Time
= $1,000 x 350% x 1/52
= $67.31.
Thus, the interest that the borrower pays for $1,000 for 1 week at 350% APR is not $52.70, $78.42, or $86.21, but $67.31.

What exactly are linear equations with two variables?
Therefore, a linear equation in two variables is any equation that can be written in the form ax + by + c = 0, where a, b, and c are real values, and a and b are not equal to zero. This implies that you can come up with a ton of these equations. Solution: It is possible to write 2x + 3y = 4.37 as 2x + 3y - 4.37 = 0.
Write the following two equations first, setting c = children and a = adults:
c + a = 2200
1.50 ( c ) + 4.00 ( a ) = 5050
Use substitution now, explains the explanation
c = 2200 − a \s 1.50 ( 2200 − a ) + 4.00 ( a ) = 5050
Reduce complexity: 2.5 a = 1750 a = 700
Using the first formula, c = 2200 a = 2200 700 = 1500
In conclusion, there were 1500 kids and 700 adults.
