A bag contains 12 counters numbered from 1 to 12. If a counter is picked at random, find
the probability that is: even, a cube number, prime or odd?
Answer:
Step-by-step explanation:
even (2, 4, 6, 8, 10, 12) = 6/12 = 1/2
cube (1, 8) = 2/12 = 1/6 (although all numbers are a cube of something, just not a whole, or even rational, number)
prime (1, 2, 3, 5, 7, 11) = 6/12 = 1/2
odd (1, 3, 5, 7, 9, 11) = 6/12 = 1/2

The total revenue for Fred's Estates LLC is given as the function R(x) = 200x -0.25x2, where x is the number of villas booked. What number of villas booked
produces the maximum revenue?
Answer:
400 villas
Step-by-step explanation:
Since R(x)=200x−0.25x2 is a quadratic function with a negative leading coefficient, it represents a parabola opening downward. So its vertex will be the maximum of the function. If the coefficients are labeled, we have a=−0.25, b=200, and c=0. Then the vertex is found as follows.
x=−b/2a=−200/2(−0.25)=400
Therefore, maximum revenue will be attained when 400 villas are booked.
The required number of villas booked that produce the maximum revenue is 400.
Given that,
The total revenue for Fred's Estates LLC is given as the function R(x) = 200x -0.25x2, where x is the number of villas booked, what number of villas booked produces the maximum revenue is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Given the equation for the villas,
R(x) = 200x -0.25x²
The above equation gives its maximum, where the slope of the function is zero,
So differentiate the function.
d/dx{200x -0.25x²} = 0
200 - 0.5x = 0
x = 400
Thus, the required number of villas booked that produce the maximum revenue is 400.

Find the slope of a line parallel
to 2y= 6x+8
The slope of a line parallel to 2y= 6x+8 is 3.
How to calculate or determine the slope of a line?In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
In Mathematics and Geometry, parallel lines are two (2) lines that are always the same (equal) distance apart and never meet. Therefore, two (2) lines are parallel under the following conditions:
m₁ = m₂
By making y the subject of formula, we have:
2y = 6x + 8
y = 3x + 4
Therefore, the slope is 3.

For what value of A is the function, (x), continuous at x=0?
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = -1
(iii) h(0) = 1/7
The value of λ must be 7, for h(x) to be continuous at x = 0.
The given function is,
h(x) = 1/7, when x = 0
= 1 - 2 cos 2x, when x < π/2
= 1 + 2 cos 2x, when x > π/2
= x cos x/sin λx, when x < 0
Now,
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^-}{2}}\) (1 - 2 cos 2x) = 1 - 2 cos π = 1 + 2 = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^+}{2}}\) (1 + 2 cos 2x) = 1 + 2 cos π = 1 - 2 = -1
(iii) h(0) = 1/7
Since the function is continuous at x = 0, so
\(\lim_{x \to 0}\) h(x) = h(0)
\(\lim_{x \to 0}\) x cos x/sin λx = 1/7
\(\lim_{x \to 0}\) cos x.\(\lim_{x \to 0}\) 1/λ(sinλx/λx) = 1/7
1/λ = 1/7
λ = 7
Hence the value of λ must be 7.

Sunset Lake is stocked with 2800 rainbow trout and after 1 year the population has grown to 7000. Assuming logistic growth with a carrying capacity of 28000, find the growth constant kk, and determine when the population will increase to 14600.
The growth constant is 1.0986 and the trout population will increase to 14600 after 2.1 years. The result is obtained by using the logistic equation.
How to find the increase of population?The increase of population can be found by using the logistic equation. It is
\(P(t) = \frac{K}{1 + Ae^{-kt} }\)
Where
P(t) = population at time t (in years)K = carrying capacityA = (K- P₀)/P₀k = growth constant of proportionalityt = time (in years)Sunset Lake is stocked with the rainbow trout. We have
P₀ = 2800P(1) = 7000K = 28000Find the growth constant k and time t when P(t) = 14600!
A = (K - P₀)/P₀
A = (28000 - 2800)/2800
A = 25200/2800
A = 9
After 1 year, we have 7000 rainbow trout. The growth constant is
\(7000 = \frac{28000}{1 + 9e^{-k(1)} }\)
\(1 + 9e^{-k} = 4\)
\(9e^{-k} = 3\)
\(e^{-k} = \frac{1}{3}\)
k = - ln (1/3)
k = 1.0986
Use k value to find the time when the population will increase to 14600!
\(14600 = \frac{28000}{1 + 9e^{-1.0986t} }\)
\(1.9178 = 1 + 9e^{-1.0986t}\)
\(0.9178 = 9e^{-1.0986t}\)
\(\frac{0.9178 }{9} = e^{-1.0986t}\)
\(t = \frac{ln \: 0.10198}{-1.0986}\)
t = 2.078
t ≈ 2.1 years
It is in another 1.1 years after t = 1.
Hence, the growth constant k is 1.0986 the population will increase to 14600 when t is 2.1 years.

P=x-2 ÷ x+1 for what value of x is P undefined
Answer:
x = - 1
Step-by-step explanation:
P = \(\frac{x-2}{x+1}\)
the denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x + 1 = 0 ( subtract 1 from both sides )
x = - 1

What is the meaning of "the cancellation laws"?
Each step of this theorem is proved below.
Given that,
S is finite,
Now enumerate all of its elements as x₁, x₂,..., x\(_{n}\).
According to the cancellation rule,
This product is independent of the order of the factors.
As a result, we can define the identity element e as this product.
It is simple to demonstrate that e meets the criteria of an identity element.
Now, let's show that every element of S has an inverse.
Let a be any element of S. Consider the set {a, a, a, ...}.
Since S is finite,
There exist positive integers m and n such that
am = an for some m > n.
By the cancellation law,
We can cancel a power of a from both sides to get a\({(m-n)}\) = e.
This means that a has an inverse, and we can conclude that S is a group.
Consider the set of all positive integers under addition, except 1, as an example of an infinite semigroup in which the cancellation laws hold but which is not a group.
This set clearly meets the cancellation laws, but it does not have an inverse for every element, because the inverse of 2, for example, is not an integer.
As a result, this is not a group.

The line given by
−11x=4y+4 is dilated by a scale factor centered at the origin. The image of the line after dilation is given by
−11x−4y=16. What is the scale factor of the dilation?
The scale factor of the dilation is 4.
We are given that;
The equation of line −11x=4y+4
Now,
The center of dilation is the origin (0, 0). The line given by −11x = 4y + 4 can be rewritten as y = −11/4 x − 1. This means that it passes through the points (0, −1) and (−4, 0). The image of the line after dilation is given by −11x − 4y = 16, which can be rewritten as y = −11/4 x − 4. This means that it passes through the points (0, −4) and (−16, 0).
To find the scale factor, we can use any pair of corresponding points. For example, let’s use (0, −1) and (0, −4). The distance from the center of dilation to (0, −1) is 1 unit. The distance from the center of dilation to (0, −4) is 4 units. Therefore, the scale factor is 4/1 = 4.

. Assume that you are considering the purchase of a 80-year, noncallable bond with an annual coupon rate of 9.5%. The bond has a face value of $1,000, and it makes semiannual interest payments. If you require an 9.7% nominal yield to maturity on this investment, what is the maximum price you should be willing to pay for the bond?
Answer: $982.48
Step-by-step explanation:
The maximum price you should pay would be the present value of the bond including its cash flows. That is how the price of a bond is computed.
The formula to calculate the price of a bond is;
\(Price = Coupon payment * \frac{1 - (1 + yield)^{-n} }{yield} + \frac{Future value}{( 1 + r) ^n}\)
The payments are semi annual so the variables will need to be converted to semi annual variables.
Coupon payment = 9.5% * 1,000 * 1/2
= $47.50
Number of periods = 20 years * 2 = 40 semi annual periods
Yield = 9.7%/2 = 4.85%
\(Price = 47.50 * \frac{1 - (1 + 0.0485)^{-40} }{0.0485} + \frac{1,000}{( 1 + 0.0485)^{40} }\\Price = 832.077 * 150.405\\Price = 982.48\)
Price = $982.48
$982.48 should be the maximum price you should pay.
Alternatively, use a financial calculator and input the variables as;
Future Value = $1,000
Payment = $47.50
Number of Periods = 40
Rate = 4.85%
