1] (a) The probability that both chosen students are women is 0.3025 or 30.25%.
To find the probability, we can use a probability tree. Let's represent the first student as A and the second student as B.
(a) To find the probability that both chosen students are women, we start with the probability of selecting a woman as the first student, which is 55%. This probability is represented by P(A=W) = 0.55. Then, for the second student, given that the first student is a woman, the probability of selecting another woman is 54% (since there is one less woman in the remaining sample). This probability is represented by P(B=W|A=W) = 0.54.
To find the probability of both events occurring, we multiply the probabilities:
P(A=W and B=W) = P(A=W) * P(B=W|A=W) = 0.55 * 0.54 = 0.297.
Therefore, the probability that both chosen students are women is 0.297 or 29.7%.
(b) To find the probability that at least one of the two students is a woman, we can calculate the complement of the probability that both students are men.
The probability that both students are men is found by multiplying the probabilities of selecting a man for each student:
P(A=M and B=M) = P(A=M) * P(B=M|A=M) = 0.45 * 0.46 = 0.207.
Then, the probability that at least one of the two students is a woman is the complement of this probability:
P(at least one woman) = 1 - P(both men) = 1 - 0.207 = 0.793.
Therefore, the probability that at least one of the two students is a woman is 0.793 or 79.3%.

The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
x + x + 120 + 90 = 360
2x + 210 = 360 ( subtract 210 from both sides )

Step-by-step explanation:
A word processing system selling firm records track of the number of customers who call on any one day and the number of orders placed on any one day. Let X, denote the number of calls, Xz denote the number of orders placed, and p( x1,x2) the joint probability function for (X1,X2); records indicate that P(0,0)= 0.06 P (2,0)= 0.20 P(1,0)= 0.14 P(2,1)= 0.30 P(1,1)= 0.10 P(2,2) = 0.20 For any given day, the probability of say, two calls and one order is 0.30. Find the correlation coefficient and interpret your results.
The correlation coefficient is:r = -0.332 / (0.683 × 0.566) = -0.994
Correlation Coefficient The correlation coefficient, denoted by r, is a statistical measure of the strength of the relationship between two quantitative variables.
It is always between -1 and 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation at all.
In this problem, we have the joint probability function for X1 and X2 as follows:
P(0,0) = 0.06P(2,0) = 0.20P(1,0) = 0.14P(2,1) = 0.30P(1,1) = 0.10P(2,2) = 0.20
The probability of two calls and one order is given as 0.30. Thus:P(2,1) = 0.30
Now, let us find the marginal probabilities of X1 and X2.P(X1 = 0) = P(0, 0) + P(0, 1) + P(0, 2) = 0.06 + 0 + 0 = 0.06P(X1 = 1) = P(1, 0) + P(1, 1) + P(1, 2) = 0.14 + 0.10 + 0 = 0.24P(X1 = 2) = P(2, 0) + P(2, 1) + P(2, 2) = 0.20 + 0.30 + 0.20 = 0.70Similarly,P(X2 = 0) = P(0, 0) + P(1, 0) + P(2, 0) = 0.06 + 0.14 + 0.20 = 0.40P(X2 = 1) = P(0, 1) + P(1, 1) + P(2, 1) = 0 + 0.10 + 0.30 = 0.40P(X2 = 2) = P(0, 2) + P(1, 2) + P(2, 2) = 0 + 0 + 0.20 = 0.20
The expected values of X1 and X2 are:
E(X1) = 0 × 0.06 + 1 × 0.24 + 2 × 0.70 = 1.64
E(X2) = 0 × 0.40 + 1 × 0.40 + 2 × 0.20 = 0.80
Let us now find the expected value of X1X2:
E(X1X2) = 0 × 0.06 + 1 × 0.00 + 2 × 0.30 + 0 × 0.14 + 1 × 0.10 + 2 × 0.20 = 1.14
Thus, the covariance of X1 and X2 is:Cov(X1, X2) = E(X1X2) - E(X1)E(X2) = 1.14 - 1.64(0.80) = -0.332
Finally, the correlation coefficient is given as
r = Cov(X1, X2) / (σ(X1)σ(X2))
Where σ(X1) is the standard deviation of X1 and σ(X2) is the standard deviation of X2.
Let us find the standard deviations of X1 and X2:
Variance of X1:Var(X1) = E(X1^2) - [E(X1)]^2 = 0^2(0.06) + 1^2(0.24) + 2^2(0.70) - (1.64)^2 = 0.4676
Standard deviation of X1:σ(X1) = √Var(X1) = √0.4676 = 0.683
Variance of X2:Var(X2) = E(X2^2) - [E(X2)]^2 = 0^2(0.40) + 1^2(0.40) + 2^2(0.20) - (0.80)^2 = 0.3200
Standard deviation of X2:σ(X2) = √Var(X2) = √0.3200 = 0.566
Thus, the correlation coefficient is:r = -0.332 / (0.683 × 0.566) = -0.994
Therefore, the correlation coefficient is very close to -1.
This means that there is a very strong negative correlation between the number of calls and the number of orders placed. This can be interpreted as follows: As the number of calls increases, the number of orders placed decreases, and vice versa.

Given the disk of the radius r = 1, i.e., = {(x₁, x₂) € R² | x² + x² <1} find the smallest and largest values that the function f(x₁, x₂) = x₁ + x₂ achieves on the set D. a) Formulate the problem as an optimization problem and write down the optimality conditions. b) Find the point(s) in which the function f achieves maximum and minimum on the set D What is the largest and smallest value of f ? Comments: Make sure that you properly justify that you find a minimizer and maximizer. c) Denote the smallest value fin. What is the relative change of fin expressed in percents if the radius of the disk decreases and it is given as D {(1,₂) € R²|x²+x≤0.99}
The smallest value of the function f(x₁, x₂) = x₁ + x₂ on the disk D with a radius of 1 is -√2, and the largest value is √2. The relative change in the smallest value, expressed in percent, can be calculated if the radius of the disk decreases to 0.99.
a) The problem can be formulated as an optimization problem with constraints. We want to find the smallest and largest values that the function f(x₁, x₂) = x₁ + x₂ achieves on the set D, which is defined as the disk with radius r = 1, i.e., D = {(x₁, x₂) ∈ ℝ² | x₁² + x₂² < 1}.
To find the smallest value, we can minimize the function f subject to the constraint that (x₁, x₂) is within the disk D. Mathematically, this can be written as:
Minimize: f(x₁, x₂) = x₁ + x₂
Subject to: x₁² + x₂² < 1
To find the largest value, we can maximize the function f subject to the same constraint. Mathematically, this can be written as:
Maximize: f(x₁, x₂) = x₁ + x₂
Subject to: x₁² + x₂² < 1
b) To find the points at which the function f achieves the maximum and minimum on the set D, we can analyze the problem. The function f(x₁, x₂) = x₁ + x₂ represents a plane with a slope of 1.
Considering the constraint x₁² + x₂² < 1, we observe that it represents a circle with radius 1 centered at the origin.
Since the function f represents a plane with a slope of 1, the maximum and minimum values occur at the points on the boundary of the disk D where the plane is tangent to the disk. In other words, the maximum and minimum values occur at the points where the plane f(x₁, x₂) = x₁ + x₂ is perpendicular to the boundary of the disk.
Considering the disk D: x₁² + x₂² < 1, we can see that the boundary of the disk is x₁² + x₂² = 1 (the equation of a circle).
At the boundary, the gradient of the function f(x₁, x₂) = x₁ + x₂ is parallel to the normal vector of the boundary circle. The gradient of f is (∂f/∂x₁, ∂f/∂x₂) = (1, 1), which represents the direction of steepest ascent of the function.
Thus, at the points where the plane f(x₁, x₂) = x₁ + x₂ is tangent to the boundary circle, the gradient of f is parallel to the normal vector of the circle. Therefore, the gradient of f at these points is proportional to the vector pointing from the origin to the tangent point.
To find the tangent points, we can use the fact that the tangent line to a circle is perpendicular to the radius at the point of tangency. The radius of the circle D is the vector from the origin to any point (x₁, x₂) on the boundary, which is (x₁, x₂).
So, the tangent points occur when the gradient vector (1, 1) is proportional to the radius vector (x₁, x₂), which means:
1/1 = x₁/1 = x₂/1
Simplifying, we get:
x₁ = x₂
Substituting this back into the equation of the boundary circle, we have:
x₁² + x₂² = 1
x₁² + x₁² = 1
2x₁² = 1
x₁² = 1/2
Taking the positive square root, we get:
x₁ = √(1/2)
Since x₁ = x₂, the corresponding values are:
x₂ = √(1/2)
Thus, the points where the function f achieves the maximum and minimum on the set D are (x₁, x₂) = (√(1/2), √(1/2)) and (x₁, x₂) = (-√(1/2), -√(1/2)).
Plugging these values into the function f(x₁, x₂) = x₁ + x₂, we get:
f(√(1/2), √(1/2)) = √(1/2) + √(1/2) = 2√(1/2) = √2
f(-√(1/2), -√(1/2)) = -√(1/2) - √(1/2) = -2√(1/2) = -√2
Therefore, the largest value of f is √2, and the smallest value of f is -√2.
c) Denoting the smallest value as fin = -√2, we can find the relative change in fin expressed in percent if the radius of the disk decreases to D = {(x₁, x₂) ∈ ℝ² | x₁² + x₂² ≤ 0.99}.
To calculate the relative change, we can use the formula:
Relative Change = (New Value - Old Value) / Old Value * 100
The new value of fin, denoted as fin', can be found by minimizing the function f subject to the constraint x₁² + x₂² ≤ 0.99.
Solving the minimization problem, we find the new smallest value fin' on the set D with a radius of 0.99.
Comparing fin' to fin, we can calculate the relative change:
Relative Change = (fin' - fin) / fin * 100
By solving the new minimization problem, you can find the new smallest value fin' and calculate the relative change using the formula provided.

Suppose you have 10 black, 10 white, 10 blue, and 10 brown socks. The minimum number of socks to pick that all 3 brothers wear the same color socks is 4 of the same color.
You are required to determine how many socks to pick blindly since there is no light in the room so all three brothers wear the same color socks. In this question, we have 4 types of socks. Therefore, we can apply Pigeonhole Principle here. Pigeonhole Principle states that If n+1 items are put into n boxes, then at least one box must contain two or more items.
Assuming that a brother needs to wear 3 socks of the same color. Therefore, for all 3 brothers to wear the same color socks, we must pick 4 socks of the same color. Therefore, the minimum number of socks that needs to be picked = 4.

The base of a right prism is a hexagon with one side 6 cm long. If the volume of the prism is 450 cc, how far apart are the bases?
Let the height of the prism be h and the apothem of the hexagonal base be a, and let the distance between the bases be d. The volume of the prism is given by the formula: V = (1/2) × 6a × h × 2 + 6 × (1/2) × 6 × a × h
[Note: The hexagon has 6 equilateral triangles as its sides. Each triangle has base 6 cm and height a. The volume of the prism is equal to the sum of the volumes of the 12 equal triangular prisms that are formed by the 12 triangular faces of the hexagonal prism]
V = 6ah + 18ah = 24ahGiven that the volume of the prism is 450 cc, we can equate this expression to 450 to obtain:450 = 24ahDividing both sides by 24a, we obtain:450 / 24a = h
The bases of the prism are parallel to each other, and each is a regular hexagon. To obtain the distance between them, we can add twice the apothem to the height of the prism: Distance between bases = 2a + h We can substitute h with the expression we derived earlier: Distance between bases = 2a + 450 / 24aFor the volume of the prism to be positive, the height and the apothem must be positive.
Therefore, the distance between the bases is also positive. We can now use calculus to minimize this expression for the distance between the bases. However, we can also use the arithmetic mean-geometric mean inequality as follows:(2a) + (450 / 24a) ≥ 2 √(2a × 450 / 24a) = √(2 × 450) = 3√50
Therefore, the distance between the bases is at least 3√50 cm. The equality holds when 2a = 450 / 24a. To show that this is indeed the minimum value of the distance between the bases, we need to demonstrate that the value is achievable. We can solve this equation for a to obtain:a² = 75/4a = √(75/4) = (5/2)√3
Therefore, the minimum value of the distance between the bases is 3√50 cm, and it is achieved when a = (5/2)√3.

Show that if c > 0, then lim Xc-Cx/Xx-Cc=1 - Inc/1+ Inc
If c > 0, then lim_(x->c) (x^c - c^x) / (x - c) = 1 - inc/1+inc.
To show that if c > 0, then lim Xc - Cx / Xx - Cc = 1, we need to make use of L'Hopital's Rule and some algebraic manipulations. Here's how to do it:
Given that c > 0, let f(x) = x^c - c^x and g(x) = x - c.
Then, the given limit is equivalent to: lim_(x->c) f'(x) / g'(x)
By differentiating f(x) and g(x), we get: f'(x) = c * x^(c-1) - c^x * ln(c) and g'(x) = 1.
So, the limit becomes: lim_(x->c) [c * x^(c-1) - c^x * ln(c)] / 1
Now, let's rewrite the numerator: [c * x^(c-1) - c^x * ln(c)] = c * (x^(c-1) - c^(x-1) * ln(c))
Therefore, the limit becomes: lim_(x->c) [c * (x^(c-1) - c^(x-1) * ln(c))] / 1
Now, we can use L'Hopital's Rule to evaluate the limit:
lim_(x->c) [c * (x^(c-1) - c^(x-1) * ln(c))] / 1
= lim_(x->c) [c * ((c-1) * x^(c-2) - (x-1) * c^(x-2) * ln(c))] / 0
= -c * ln(c) * lim_(x->c) (x-1) * c^(x-2) / ((c-1) * x^(c-2))
Now, let's evaluate the limit inside the parentheses:
lim_(x->c) (x-1) * c^(x-2) / ((c-1) * x^(c-2))
= lim_(x->c) (x/c)^(c-2) * (x-1)/(c-1)
We can simplify the above expression as follows:
(x-1)/(c-1)
= (x-c+c-1)/(c-1)
= (x-c)/(c-1) + (c-1)/(c-1)
= (x-c)/(c-1) + 1
Therefore, the limit becomes:
lim_(x->c) -c * ln(c) * [(x-c)/(c-1) + 1]
= lim_(x->c) -c * ln(c) * (x-c)/(c-1) - c * ln(c)
= 1 - inc/1+inc
Hence, we have shown that if c > 0, then lim_(x->c) (x^c - c^x) / (x - c) = 1 - inc/1+inc.

If they make payments of $3,000 every four months for the first five years how does this change your answer to part d?
If they make additional payments of $3,000 every four months for the first five years, it will reduce the outstanding balance on the mortgage.
What is their monthly rate to be applied to the mortgage?To calculate the values requested, we'll need to perform various calculations based on the given information. Let's go step by step:
Monthly Interest Rate:
The mortgage rate provided is 4.9% compounded semi-annually. To calculate the monthly interest rate, we need to convert the semi-annual rate to a monthly rate. Since there are two compounding periods per year, we divide the annual interest rate by two and then convert it to a decimal:
Monthly interest rate = (4.9% / 2) / 100 = 0.0245
Monthly Payments:
To calculate the monthly payments, we can use the formula for the monthly payment of a mortgage:
Monthly Payment = (Loan Amount - Down Payment) * (Monthly Interest Rate / (1 - (1 + Monthly Interest Rate)^(-Number of Months)))
Loan Amount = $460,000 - (10% * $460,000) = $414,000
Number of Months = 25 years * 12 months/year = 300 months
Substituting these values into the formula, we can calculate the monthly payments:
Monthly Payment = ($414,000) * (0.0245 / (1 - (1 + 0.0245)^(-300)))
Amount Owed after 5 Years:
After five years, the number of months remaining on the mortgage is 25 years - 5 years = 20 years = 240 months. To find out how much they owe after the first five years, we need to calculate the remaining balance on the mortgage:
Remaining Balance = Loan Amount * (1 + Monthly Interest Rate)^Number of Months - Total Payments
In this case, the Loan Amount is $414,000, the Monthly Interest Rate is 0.0245, and the Number of Months is 240. To calculate the Total Payments, we can multiply the Monthly Payment by the number of months paid during the first five years (5 years * 12 months/year = 60 months).
Interest Paid in the First Five Years:
To determine the interest paid in the first five years, we can subtract the remaining balance after five years from the initial loan amount:
Interest Paid = Loan Amount - Remaining Balance
New Semi-Monthly Payments after Renegotiation:
If they renegotiate the mortgage at a new rate of 5.9%, compounded semi-annually, and plan to pay off the remaining balance from part c, we need to recalculate the monthly payments.
We can use a similar formula as in part b, substituting the remaining balance (from part c) as the new loan amount, and the semi-monthly interest rate based on the new mortgage rate.
Payments of $3,000 every Four Months in the First Five Years:
To calculate the new interest paid in the first five years, we need to consider the reduced balance resulting from the additional payments and then subtract this balance from the initial loan amount.
Now, let's perform the calculations and find the values for each part.

Slice of a cake
Answer:
The correct answer in each case is:
Surface area = 60 [tex]cm^{2}[/tex]Surface area = 6000 [tex]mm^{2}[/tex]Surface area = 0.006 [tex]m^{2}[/tex] Volume = 1200 [tex]cm^{3}[/tex]Step-by-step explanation:
First, to calculate the surface area or the volume you must have all the measures in the same units, for the exercise we're gonna use centimeters and after we can replace the units in the answer if we need, then:
300 mm = 30 cm 40 cm 50 cm 2 dm = 20 cmNow, to obtain the surface area of the triangle we're gonna use the next formula:
Surface area = (base * height) / 2And we replace the values in centimeters:
Surface area = (30 cm * 40 cm) / 2Surface area = (120 [tex]cm^{2}[/tex]) / 2Surface area = 60 [tex]cm^{2}[/tex]To obtain this same value now in square milimeters, you must know:
1 [tex]cm^{2}[/tex] = 100 [tex]mm^{2}[/tex]Now, you must multiply:
60 [tex]cm^{2}[/tex] * 100 = 6000 [tex]mm^{2}[/tex]60 [tex]cm^{2}[/tex] = 6000 [tex]mm^{2}[/tex]To obtain this value now in [tex]m^{2}[/tex], you must know:
1 [tex]m^{2}[/tex] = 10000 [tex]cm^{2}[/tex]You must divide:
60 [tex]cm^{2}[/tex] / 10000 = 0.006 60 [tex]cm^{2}[/tex] = 0.006 [tex]m^{2}[/tex]By last, to obtain the volume of the piece of cake, you can use the next formula:
Volume of the piece of cake: surface area * depthAnd we replace the surface area in [tex]cm^{2}[/tex] because the answer must be in [tex]cm^{3}[/tex]:
Volume of the piece of cake: 60 [tex]cm^{2}[/tex] * 20 cmVolume of the piece of cake: 1200 [tex]cm^{3}[/tex]Can you help me please thank you
