The probability of drawing a green card on both the first and second draw, with replacement, is 25/64, as each draw is an independent event with the same probability of 5/8 for drawing a green card.
Explanation:The problem is asking us to compute the probability of drawing two green cards in succession, with replacement, from a deck that contains eight cards of which five are green and three are yellow. Since the draws are independent and with replacement, the probability of an event occurring on the first draw is not affected by the second draw, and vice versa.
To calculate the probability of drawing a green card on the first draw, denoted as P(G₁), we look at the number of green cards and the total number of cards. There are 5 green cards out of 8 total cards, so P(G₁) = 5/8.
Because we are replacing the drawn card before the second draw, the probability of drawing a green card on the second draw, denoted as P(G₂), remains the same as for the first draw, thus P(G₂) = 5/8.
The probability of both events happening, denoted as P(G₁ and G₂), is the product of the individual probabilities since the draws are independent. Therefore, we have:
P(G₁ and G₂) = P(G₁) * P(G₂) = (5/8) * (5/8) = 25/64.

Identify the percent of change as an increase or a decrease. 68 miles to 42.5 miles
Final answer:
The distance changing from 68 miles to 42.5 miles represents a 37.5% decrease, calculated using the percent change formula.
Explanation:
The question involves calculating the percent of change when the distance changes from 68 miles to 42.5 miles. To find the percent of change, we use the formula: Percent Change = ((New Value - Original Value) / Original Value) x 100%. Here, the original value is 68 miles and the new value is 42.5 miles.
Plugging in the values, we get: Percent Change = ((42.5 - 68) / 68) x 100% = (-25.5 / 68) x 100% ≈ -37.5%. Because the result is negative, this indicates a decrease in the distance traveled.
Therefore, the distance changing from 68 miles to 42.5 miles represents a 37.5% decrease.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Model Equation : t – 3.5 = 22.5
where t is Terrance’s age.
Now, solving the equation for t we get
t - 3.5 = 22.5
Add 3.5 on both side
t -3.5+ 3.5 = 22.5 + 3.5
t = 26
Hence, Terrance age is 26 years.

If x denotes the length of a side of an equilateral triangle, express the area of the triangle as a function of x.
Using the concept of an equilateral triangle, it is found that it's area is given by:
[tex]A = \frac{\sqrt{3}}{4}x^2[/tex]
In an equilateral triangle, all sides have the same length.The area of a triangle is one half of the base multiplied by the height.For the equilateral triangle in this problem, the base is x, that is, [tex]b = x[/tex]The height is one side of a right triangle, in which the other side is half the base and the other is the base, thus, applying the Pythagorean Theorem:
[tex]h^2 + (\frac{x}{2})^2 = x^2[/tex]
[tex]h^2 + \frac{x^2}{4} = x^2[/tex]
[tex]h^2 = \frac{3x^2}{4}[/tex]
[tex]h = \sqrt{\frac{3x^2}{4}}[/tex]
[tex]h = \frac{\sqrt{3}}{2}x[/tex]
Then, the area is:
[tex]A = \frac{bh}{2} = \frac{1}{2} \times x \times \frac{\sqrt{3}}{2}x = \frac{\sqrt{3}}{4}x^2[/tex]

Given that (-2,-5) is on the graph of f(x), find the corresponding point for the function f(-2/3x).
The corresponding point for the function f(-2/3x) given the point (-2,-5) on the graph of f(x) is (3,-5), where the x-coordinate is transformed by multiplying -2 by -3/2 and the y-coordinate remains unchanged.
The question asks about finding a corresponding point for the function f(-2/3x) given that the point (-2,-5) is on the graph of the original function f(x). To find the corresponding point, we need to apply the transformation to the x-coordinate of the given point. Since the function is f(-2/3x), this represents a horizontal stretch by the reciprocal of -2/3, which is -3/2. Therefore, we multiply the x-coordinate of the given point by -3/2.
Let's calculate this step by step:
Start with the original point (-2,-5).Apply the transformation to the x-coordinate: -2 multiplied by -3/2 equals 3.The y-coordinate remains unchanged because the transformation applies only to the x-coordinate.C. what is the probability that the flight will be more than 10 minutes late (to 2 decimals)?

At a recent boat show, Boater's Paradis sold five more boats than Pelican Marine sold. If together they sold 33 boats, how many were sold by each company?
In this mathematics problem about boat sales, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats. This conclusion was achieved by forming and solving a simple algebraic equation based on the provided problem information.
Explanation:To solve this problem, let's visualize it first. Pelican Marine sold a certain number of boats, and Boater's Paradis sold 5 more than that. If we call the number of boats sold by Pelican Marine as x, and adding Boater's Paradis' sales (x + 5), together they sold 33 boats. So we form the equation as x + (x+5) = 33.
Solving that equation, we will get 2x + 5 = 33, then simplify it to 2x = 28 after subtracting 5 from both sides. Finally, we divide both sides by 2 we get x = 14.
So, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats (14 boats Pelican Marine sold plus an additional 5 Boater's Paradis sold).

Gymnast Clothing manufactures expensive soccer cleats for sale to college bookstores in runs of up to 500. Its cost (in dollars) for a run of x pairs of cleats is C(x) = 2750 + 8x + 0.1x2 (0 ≤ x ≤ 500). Gymnast Clothing sells the cleats at $100 per pair. Find the revenue and profit functions. How many should Gymnast Clothing manufacture to make a profit?
Answer:

Step-by-step explanation:
The cost (in dollars) for a run of x pairs of cleats.
[tex]C(x)=2750 + 8x + 0.1x^2[/tex]
Gymnast Clothing sells the cleats at $100 per pair.
The Revenue (in dollars) for a run of x pairs of cleats.
[tex]R(x)=100x[/tex]
Profit = Revenue - Cost
[tex]P(x)=R(x)-C(x)[/tex]
[tex]P(x)=100x-(2750 + 8x + 0.1x^2)[/tex]
[tex]P(x)=-0.1 x^2 + 92 x - 2750[/tex]
We need to find how many should Gymnast Clothing manufacture to make a profit.

A 3x3x4 cuboid is painted blue and cut into 1x1 cubes. what is the expected value for the painted sides of a randomly selected cube?
A 3 x 3 x 4 cuboid can be cut into 3(3) (4) = 36 pieces of 1 x 1 cubes.
Out of the 36 pieces of 1 x 1 cubes, there are no 1 x 1 cube with the four
sides painted, there are eight 1 x 1 cubes with simply 3 sides painted, there
are twenty 1 x 1 cubes with only 2 sides tinted, there are 6 cubes with only 1
side painted and there are 2 cubes with no side painted.
The chance that the four sides of a randomly selected cube is painted is 0.
The likelihood that only 3 sides of a randomly selected cube is painted is 8 / 36 = 2 / 9.
The chance that only 2 sides of a randomly selected cube is painted is 20 / 36 = 5 / 9.
The likelihood that only 1 side of a randomly selected cube is painted is 6 / 36 = 1 / 6.
The probability that no side of a randomly selected cube is
painted is 2 / 36 = 1 / 18.
Thus, the expected value for the painted sides of a randomly selected cube is
given by 4(0) + 3(2 / 9) + 2(5 / 9) + 1(1 / 6) + 0( 1 / 18) = 2 / 3 + 10 / 9 +
1 / 6 = 35 / 18 = 1.94
