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).

At a wedding reception, the bride and groom and five attendants will form a receiving line. How many ways can they be arranged in each of following cases? a) Any order will do. b) The bride and groom must be the last two in line. c) The groom must be last in line with the bride next to him.
A. In this case, they can be arranged at any order. Since there are 7 people all in all, therefore the number of arrangements is:
number of arrangements = 7P7 = 5040 ways
B. In this case, only the 5 people can be arranged in any order therefore 5P5. However the groom and bride can be interchanged on 2 places, therefore:
number of arrangements = 5P5 * 2 = 240 ways
C. In this case, only the 5 people can be arranged in any order while the groom and bride can no longer be interchanged, therefore:
number of arrangements = 5P5 = 120 ways
Final answer:
The arrangements for the wedding reception receiving line can be calculated using permutations: a) Any order will do, giving 7!, b) The bride and groom must be the last two in line, giving 5!, c) The groom must be last in line with the bride next to him, giving 6! x 2.
Explanation:
The question asks about the number of ways a bride and groom along with five attendants can be arranged in a receiving line at a wedding reception under different conditions. This is a permutations problem where we calculate the arrangements using factorial notation.
Case a: Any order will do.
In this case, we have a total of 7 people (bride, groom, and five attendants) who can be arranged in any order. The number of arrangements is the factorial of 7, which is calculated as 7! (7 factorial). So, the number of ways they can be arranged is 7! (which is 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5,040 ways).
Case b: The bride and groom must be the last two in line.
Since the bride and groom's positions are fixed at the end of the line, we only need to arrange the five attendants. This is equivalent to 5! arrangements for the attendants. Thus, the number of ways they can be arranged is 5! (which is 5 x 4 x 3 x 2 x 1 = 120 ways).
Case c: The groom must be last in line with the bride next to him.
Here, the bride and groom are fixed in the last two positions, but the bride must be next to the groom. We consider the bride and groom as a single unit in addition to the five attendants. This gives us 6! arrangements for the attendants and the bride-groom unit, multiplied by 2 because the bride and groom can switch places within their unit. So, the number of ways they can be arranged is 6! x 2 (which is 6 x 5 x 4 x 3 x 2 x 1 x 2 = 1,440 ways).

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.

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.
[tex]P(x)\geq 0[/tex]
[tex]-0.1 x^2 + 92 x - 2750\geq 0[/tex]

The value of x can not be more than 500.
31 ≤ x ≤ 500
31 to 500 Gymnast Clothing are manufactured 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

solve the system by elimination -2x+2y+3z=0
-2x-y+z=-3
2x+3y+3z=5
The solution of the given system of linear equation would be x = 1, y = 1, and z = 0.
What is a linear equation?A linear equation is one in which the greatest power of the variable is always one.
The given system of linear equation as:
-2x+2y+3z=0 ...(i)
-2x-y+z=-3 ...(ii)
2x+3y+3z=5 ...(iii)
Adding the third equation to the (i) and (ii), we get
5y+6z=5
2y+4z=2
Multiplying the equation(ii) by -6/4 and after adding to get
⇒2y=2
Dividing both sides by 2.
⇒y=1
Substitute the value of y=1 into 2y+4z=2, and we get
⇒2+4z=2
Subtracting 2 from both sides, we get
⇒ z = 0
Substitute the values of y=1 and z=0 into -2x-y+z=-3, we get -2x-1+0=-3
By adding 1 to both sides, we get -2x=-2
By dividing both sides by -2, we get x=1
Therefore, the solution of the given system of linear equation would be x = 1, y = 1, and z = 0.

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.Find the derivative of f (x)=(x^2+1)^3 (x^2+2)^6 using chain rule.
