Answer:
To find the values of the other three angles in a pentagon given that the sum of all angles is 450 degrees and one angle is 150 degrees, we can use the fact that the sum of the angles in any polygon with n sides is (n-2) * 180 degrees.
Let's denote the other three angles as A, B, and C.
The sum of the angles in a pentagon is given as 450 degrees, so we have:
150 + A + B + C = 450
We know that the sum of the angles in a pentagon is (5-2) * 180 = 540 degrees, so we have another equation:
A + B + C = 540
Now we have a system of two equations with two variables. We can solve this system to find the values of A, B, and C.
The correct subtraction should be:
(150 + A + B + C) - (A + B + C) = 540 - 450
Simplifying the equation, we have:
150 = 90This equation is not valid, which means that the values given for the sum of angles and one angle are inconsistent with a pentagon. The sum of the angles in a pentagon should be 540 degrees. Please ensure the accuracy of the provided values.
how much money deposited now will provide payment of Rs. 15000 at the end of each half year for 10 years, if interest is 16% compounded six-monthly
The interest is 16% compounded semi-annually, is Rs. 121,179.10.
To determine how much money needs to be deposited now to provide a payment of Rs. 15,000 at the end of each half year for 10 years, we will use the formula for the present value of an annuity.
Present value of an annuity = (Payment amount x (1 - (1 + r)^-n))/rWhere:r = interest rate per compounding periodn = number of compounding periodsPayment amount = Rs. 15,000n = 10 x 2 = 20 (since there are 2 half years in a year and the payments are made for 10 years)
So, we have:r = 16%/2 = 8% (since the interest is compounded semi-annually)Payment amount = Rs. 15,000Using the above formula, we can calculate the present value of the annuity as follows:
Present value of annuity = (15000 x (1 - (1 + 0.08)^-20))/0.08 = Rs. 121,179.10Therefore, the amount that needs to be deposited now to provide payment of Rs. 15,000 at the end of each half year for 10 years, if the interest is 16% compounded semi-annually, is Rs. 121,179.10.

A triangle LMN with ln = 12 cm,Nm= x cm, Nk = 6cm and Km 8cm
Calculate the value of
(i) x
(ii) o
The value of x is 9 cm, and angle O is 0 degrees.
To solve the triangle LMN and find the values of x and angle O, we can use the Law of Cosines and the Law of Sines. Let's go step by step:
(i) To find the value of x, we can use the Law of Cosines. According to the Law of Cosines, in a triangle with sides a, b, and c, and angle C opposite to side c, the following equation holds:
c^2 = a^2 + b^2 - 2ab * cos(C)
In our case, we want to find side NM (x), which is opposite to angle N. The given sides and angles are:
LN = 12 cm
NK = 6 cm
KM = 8 cm
Let's denote angle N as angle C, side LN as side a, side NK as side b, and side KM as side c.
Using the Law of Cosines, we can write the equation for side NM (x):
x^2 = 12^2 + 6^2 - 2 * 12 * 6 * cos(N)
We don't know the value of angle N yet, so we need to find it using the Law of Sines.
(ii) To find angle O, we can use the Law of Sines. According to the Law of Sines, in a triangle with sides a, b, and c, and angles A, B, and C, the following equation holds:
sin(A) / a = sin(B) / b = sin(C) / c
In our case, we know angle N and side NK, and we want to find angle O. Let's denote angle O as angle A and side KM as side b.
We can write the equation for angle O:
sin(O) / 8 = sin(N) / 6
Now, let's solve these equations step by step to find the values of x and angle O.
To find angle N, we can use the Law of Sines:
sin(N) / 12 = sin(180 - N - O) / x
Since we know that the angles in a triangle add up to 180 degrees, we can rewrite the equation:
sin(N) / 12 = sin(O) / x
Now, we can substitute the equation for sin(O) from the Law of Sines into the equation for sin(N):
sin(N) / 12 = (6 / 8) * sin(N) / x
Now, we can solve this equation for x:
x = (12 * 6) / 8 = 9 cm
So, the value of x is 9 cm.
To find angle O, we can substitute the value of x into the equation for sin(O) from the Law of Sines:
sin(O) / 8 = sin(N) / 6
sin(O) / 8 = sin(O) / 9
9 * sin(O) = 8 * sin(O)
sin(O) = 0
This implies that angle O is 0 degrees.
Therefore, the value of x is 9 cm, and angle O is 0 degrees.

The figure for the given question is provided here :
y = x²
y = 1,002x - 2,000
If (x₁, y₁) and (x2, y2) are distinct
solutions to the system of equations
shown, what is the sum of ₁ and ₂?
X1
Answer:
To find the sum of x₁ and x₂, we need to solve the system of equations:
y = x² ...(1)
y = 1,002x - 2,000 ...(2)
Since both equations are equal to y, we can set them equal to each other:
x² = 1,002x - 2,000
To solve this quadratic equation, we can rearrange it into standard form:
x² - 1,002x + 2,000 = 0
Now, we can factorize the equation:
(x - 2)(x - 1,000) = 0
Setting each factor equal to zero, we get two solutions:
x - 2 = 0 => x = 2
x - 1,000 = 0 => x = 1,000
Therefore, the values of x₁ and x₂ are 2 and 1,000, respectively.Therefore, the values of x₁ and x₂ are 2 and 1,000, respectively.The sum of x₁ and x₂ is:Therefore, the values of x₁ and x₂ are 2 and 1,000, respectively.The sum of x₁ and x₂ is:x₁ + x₂ = 2 + 1,000 = 1,002The sum of distinct solutions x₁ and x₂ to the system of equations y = x² and y = 1,002x - 2,000 is 1,002.
Explanation:The problem here involves finding the solutions to the system of equations. Those equations are y = x² and y = 1,002x - 2,000. To solve this system of equations, we can set the two equations equal to each other, because they both equal y.
So, we have: x² = 1,002x - 2,000. Rearranging, we get x² - 1,002x + 2,000 = 0. This is a quadratic equation, and we can solve for x using the quadratic formula: x = [1,002 ± sqrt((1,002)² - 4*1*2,000)] / (2*1). This will yield 2 solutions for x, let's call them x₁ and x₂.
The question asks for the sum of x₁ and x₂. In a quadratic equation ax² + bx + c = 0, the sum of solutions is given by -b/a. Here, a = 1 and b = -1,002, so the sum of solutions x₁ and x₂ is -(-1,002)/1 = 1,002.

At a certain college, 49% of the students are male and 51% are female. In addition, 20% of the men and
10% of the women are taking Japanese classes. The student is selected at random. If the selected student
attends Japanese lessons, what is the probability that the student is female?
Answer:
0.339, or approximately 33.9%
Step-by-step explanation:
We can solve this problem using Bayes' theorem. Let F denote the event that the selected student is female, and J denote the event that the selected student is taking Japanese classes. We want to find the probability of F given J, which we can write as P(F|J).
Using the law of total probability, we can decompose the probability of J as follows:
P(J) = P(J|F)P(F) + P(J|M)P(M)
where M denotes the event that the selected student is male. We can calculate the probabilities on the right-hand side of this equation as follows:
P(J|F) = 0.1 (from the problem statement)
P(F) = 0.51 (from the problem statement)
P(J|M) = 0.2 (from the problem statement)
P(M) = 0.49 (from the problem statement)
Plugging in these values, we get:
P(J) = 0.10.51 + 0.20.49 = 0.149
Now we can use Bayes' theorem to find P(F|J):
P(F|J) = P(J|F)P(F) / P(J)
Plugging in the values we calculated earlier, we get:
P(F|J) = 0.1*0.51 / 0.149 = 0.339
Therefore, the probability that the selected student is female given that they attend Japanese classes is 0.339, or approximately 33.9%.

Given a circle of radius 21cm correct to the nearest cm. What is the possible maximum error when calculating its area?
Answer:
:)
Step-by-step explanation:
This is a calculus problem that involves using differentials to estimate the maximum error in the area of a circle given the error in its radius. According to 1, the errors are related by ΔA=drdAΔr=2πrΔr
Therefore, Δr=2πrΔA
If the radius is 21 cm correct to the nearest cm, then the possible error in the radius is ±0.5 cm. Using this value in the formula above, we get ΔA=2π(21)(0.5)≈65.97 cm2
This is the possible maximum error when calculating the area of a circle with radius 21 cm correct to the nearest cm.

A party is attended by n > 2 people. Prove that there will always be two people in attendance who have
the same number of friends at the party.
(The relation “is a friend of” is symmetric.)
It should be noted that there will always be two people in attendance who have the same number of friends at the party using the pigeonhole principle.
How to explain the informationThe pigeonhole principle states that if you have n pigeons and m pigeonholes, and n > m, then at least one pigeonhole must contain more than one pigeon.
In this case, we have n people at the party, and there are m = n - 1 possible numbers of friends that a person can have. This is because a person can either know 0, 1, 2, ..., or n - 1 other people.
Since n > m, the pigeonhole principle tells us that at least two people at the party must have the same number of friends.
