Mr. A sold his land to Mr.B at a profit of 10%. Mr.B. sold it to Mr.C at a gain of 5%. Mr.C.paid N1240 more for the house than Mr. A paid. What did Mr. A paid.
Answers
Answer:
Mr. A initially paid approximately N8000 for the land.
Step-by-step explanation:
Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.
Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.
Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.
Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240
Step 5: Simplifying the equation: 1.155x - x = N1240
Step 6: Solving for x: 0.155x = N1240
x = N1240 / 0.155
x ≈ N8000
Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.
A system of linear equations is shown below, where A and B are real numbers.
3x + 4y = A
Bx – 6y = 15
What values could A and B be for this system to have no solutions?
Answers
Answer:
A = 0; B = -9/2
Step-by-step explanation:
To have no solutions, you need parallel lines with equal slopes and different y-intercepts.
3x + 4y = A Eq. 1
Bx - 6y = 15 Eq. 2
In Eq. 1, notice that the coefficient of x is 3/4 of the coefficient of y.
We must have the same ratio for the coefficients in Eq. 2.
B/(-6) = 3/4
4B = -6(3)
4B = -18
B = -9/2
Now we have
3x + 4y = A Eq. 1
-9/2 x - 6y = 15 Eq. 2
How do we change the left side of the second equation into the left side of the first equation? -6/4 = -3/2 and also -9/2 ÷ 3 = -3/2
To change the left side of the second equation into the left side of the first equation, divide the left side by -3/2.
If we divide 15 by -3/2 we get -10.
The equation -9/2 x - 6y = -10 is the same as Eq. 1, so that would create a system of equations with only one equation and an infinite number of answers.
To have no equations, the y-intercepts must be different, so A can be any number other that -10.
Answer: A = 0; B = -9/2

Suppose 50% of recent college graduate plan on pursuing a graduate degree. 14 recent college graduates are randomly selected
Answers
The probability that not more than 5 graduates plan to pursue a graduate degree is 0.0191.
Given Information
Percentage of college graduates that plan on pursuing a graduate degree=50%
Number of graduates selected=14
Let us consider the event that a college graduate plans on pursuing a graduate degree as a success.
The probability of getting success is p = 0.50
Let X denotes the event of success.
We have, n = 14.
Then,
X∼Bin(14,0.50).
The pmf of X is given as,
\(P(X)= ^nC_xP^x(1-P)^n^-^x\\\\P(X)= ^1^4C_x(0.50)^x(0.50)^1^4^-^x\)
The probability that not more than 5 graduates plan to pursue a graduate degree can be computed as,
P(X≤5)=5∑¹⁴Cₓ(0.50)x(0.50)¹⁴⁻ˣ
=0+0.00001+0.00012+0.00081+0.00396+0.01425
P(X≤5)=0.01914
Hence, the probability that not more than 5 graduates plan to pursue a graduate degree is 0.0191.
The probability that exactly 7 of the college graduates plan to pursue a graduate degree can be computed as,
P(X=7)=¹⁴C₇(0.5)⁷(0.5)⁹
P(X=7)=0.08395
Therefore, the probability that exactly 7 of the college graduates plan to pursue a graduate degree is 0.0840.
The probability that at least 9 but not more than 14 of the college graduates plan to pursue a graduate degree can be computed as,
P(9≤X≤14)=14∑x=9 ¹⁴Cₓ(0.50)x(0.50)¹⁴⁻ˣ
P(9≤X≤14)=0.18889+0.19833+0.16227+0.10142+0.04681+0.01505
P(9≤X≤14)=0.71277

"If you plotted the points in the table and connected them in order with a smooth curve, what shape would it be?'' a U shape
Step-by-step explanation: just took it :)
The table to complete will have values of the function f(x) at x = 0, 2, 3, with f(0) = x, f(2) = y, and f(3) = z. Values of x, y, and z are given as follows:
x = 6
y = -2
z = 0
What are functions?A function(say f(x)) is an expression in x, which for all possible values of x, in a given domain, gives a single value f(x).
How do we solve the given question?In the question, we are asked to complete a table, with the first column containing values of x and the second column a function f(x) = 2x² - 8x + 6.
Column 2 has missing values x, y, and z, when x = 0, 2, 3 respectively.
To complete the table, we find the values of f(0), f(2), and f(3).
f(0) = 2(0)² -8(0) + 6 = 0 - 0 + 6 = 0.
f(2) = 2(2)² - 8(2) + 6 = 2(4) - 16 + 6 = 8 -16 + 6 = -2.
f(3) = 2(3)² - 8(3) + 6 = 2(9) - 24 + 6 = 18 -24 + 6 = 0.
So, the table completes by putting the values of x, y, and z as:
x = 6, y = -2, and z = 0.

use mathematical induction to prove n< 2^n
Answers
**Base Case:**
When n=1, the statement becomes 1 < 2^1, which is true.
**Inductive Hypothesis:**
Assume that for some integer k, k < 2^k.
**Inductive Step:**
We need to show that k+1 < 2^(k+1).
We know that k < 2^k by our inductive hypothesis. Also, we know that 2^k < 2^k+1 because multiplying a number by 2 is equivalent to shifting its binary representation to the left by one position.
Therefore,
k < 2^k < 2^k+1
Adding 1 to both sides of the inequality chain, we get:
k+1 < 2^k+1
Multiplying both sides by 2, we get:
2(k+1) < 2^(k+1)
Since 2^(k+1) = 2*2^k, we get:
2(k+1) < 2*2^k
k+1 < 2^k
This completes the inductive step.
Therefore, by mathematical induction, the statement n < 2^n is true for all positive integers n.

The correct option is (d). The solid obtained by rotating the region in the first quadrant bounded by the curves x = y and x = y2 around the y axis
The difference between the areas beneath the two curves that form a boundary is the area between the curves. You will then have the area between the two curves, or the difference, between them.

A child pulls a wagon with a force of pounds. the handle of the wagon makes an angle of with the ground. express the force vector f in terms of i and j .
Answers
To express the force vector F in terms of the unit vectors i and j, we can use trigonometric functions to decompose the force into its horizontal and vertical components.
The force vector F can be decomposed into its horizontal and vertical components using trigonometry. Let's assume the force magnitude is represented by the value "pounds" and the angle made by the handle with the ground is represented by θ. The horizontal component of the force, denoted as Fx, can be calculated by multiplying the force magnitude by the cosine of the angle: Fx = pounds * cos(θ). The horizontal component represents the force in the x-direction.
The vertical component of the force, denoted as Fy, can be calculated by multiplying the force magnitude by the sine of the angle: Fy = pounds * sin(θ). The vertical component represents the force in the y-direction.
Therefore, the force vector F can be expressed in terms of the unit vectors i and j as F = Fx * i + Fy * j. The i and j unit vectors represent the horizontal and vertical directions, respectively. By multiplying the components of the force vector by their respective unit vectors, we obtain the force vector expressed in terms of i and j.

r = rate (as a decimal fraction).
So we have:
7160.06 = P(1 + 0.026/4)^16
7160.06 = P * 1.109227
P = 7160.06 / 1.109227

what is the answer to using the foil method (2x - 1/2) 2
Answers
Answer:
To use the FOIL method to simplify the expression (2x - 1/2)^2, follow these steps:
F: Multiply the first terms in each set of parentheses:
(2x) * (2x) = 4x^2
O: Multiply the outer terms in each set of parentheses:
(2x) * (-1/2) = -x
I: Multiply the inner terms in each set of parentheses:
(-1/2) * (2x) = -x
L: Multiply the last terms in each set of parentheses:
(-1/2) * (-1/2) = 1/4
Now, combine the like terms:
4x^2 - x - x + 1/4
Simplify by combining like terms:
4x^2 - 2x + 1/4
Therefore, (2x - 1/2)^2 = 4x^2 - 2x + 1/4.
