Answer
Answers
Answer:
Legon fo)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Dataset 1 (in increasing order)
{1, 4, x, 8}
Dataset 2 (in increasing order)
{2, 5, y, 9}
Median of dataset 1
[4 + x] / [2]
Median of dataset 2
[5 + y] / [2]
since the medians of the two given sets of data are the same,
=> [4 + x] / [2] = [5 + y] / [2]
=> 2(5 + y) = 2(4 + x)
=> 10 + 2y = 8 + 2x
=> 2y - 2x = 8 - 10
=> 2y - 2x = - 2
=> 2(y - x) = - 2
=> [2(y - x)] / [2] = [- 2] / [2]
denominators and numerators cancel out
=> (y - x) = - 1
Therefore, (y - x) ² = (-1)²
=> (y - x) ² = 1
Suppose that a scarf company estimates that its monthly cost is
C(a)=500x2 + 300 and its monthly revenue is
R(x) = -0.523 +6002-200+300, where x is in thousands of
scarves sold. The profit is the difference between the revenue and the cost.
What is the profit function, P(x)?
Answers
The profit function is P(x) = -500.523x^2 + 600x - 200.
To find the profit function, P(x), we need to subtract the cost function, C(a), from the revenue function, R(x).
Given:
Cost function: C(a) = 500x^2 + 300
Revenue function: R(x) = -0.523x^2 + 600x - 200 + 300
Profit function, P(x), is obtained by subtracting the cost function from the revenue function:
P(x) = R(x) - C(a)
P(x) = (-0.523x^2 + 600x - 200 + 300) - (500x^2 + 300)
Simplifying the expression:
P(x) = -0.523x^2 + 600x - 200 + 300 - 500x^2 - 300
P(x) = -500x^2 - 0.523x^2 + 600x + 300 - 200 - 300
P(x) = -500x^2 - 0.523x^2 + 600x - 200
Combining like terms:
P(x) = (-500 - 0.523)x^2 + 600x - 200
Simplifying further:
P(x) = -500.523x^2 + 600x - 200

If $5.00 were invested at 3% interest 600 years ago, how much would that investment be worth today?
Answers
A = P * (1 + r/n)^(n*t)
Where:
A = the future value of the investment
P = the principal amount (initial investment)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years
In this case, the principal amount (P) is $5.00, the annual interest rate (r) is 3% (or 0.03 as a decimal), the investment has been held for 600 years (t), and the interest is compounded annually (n = 1).
Plugging these values into the formula, we get:
A = 5 * (1 + 0.03/1)^(1*600)
Calculating this expression:
A = 5 * (1.03)^600
A ≈ 5 * 37.282
A ≈ 186.41
Therefore, the $5.00 investment would be worth approximately $186.41 today after 600 years at a 3% interest rate.

60ft by 60ft wall and a mirror that’s 60ft by 20ft the mirror covers wat percent of the wall?
Answers
Answer:
okay, so we have a wall that is 60 ft. The area of the wall because the wall is a square is just side squared. So the area of the wall is \(60^{2}\), which is 30 600 square feet. The mirror is 20 ft by 60 ft. So the area of the mirror, because its a rectangle is length times width, so that's 20 a 60 so 20 x 60 is gonna give me 1200 square feet. So if we take the area of the mirror and put that over the area, the wall we get 1200 over 30 600, which reduces to one over three. So the mirror is one third the area of the wall.

\(f(1.999) = 0.499875\)
\(f(1.9999) = 0.499987\)
Step-by-step explanation:
Given
\(f(x) = \frac{x^2 - 2x}{x^2 - 4}\)
Solve for f(x) for all given values of x
First, we need to simplify f(x)
\(f(x) = \frac{x^2 - 2x}{x^2 - 4}\)
\(f(x) = \frac{x(x - 2)}{x^2 - 2^2}\)
\(f(x) = \frac{x(x - 2)}{(x- 2)(x + 2)}\)
\(f(x) = \frac{x}{x + 2}\)
When \(x = 2.1\)
\(f(x) = \frac{x}{x + 2}\)
\(f(2.1) = \frac{2.1}{2.1 + 2}\)
\(f(2.1) = \frac{2.1}{4.1}\)
\(f(2.1) = 0.512195\)
When \(x = 2.05\)
\(f(x) = \frac{x}{x + 2}\)
\(f(2.05) = \frac{2.05}{2 + 2.05}\)
\(f(2.05) = \frac{2.05}{4.05}\)
\(f(2.05) = 0.506173\)
When \(x = 2.01\)
\(f(x) = \frac{x}{x + 2}\)
\(f(2.01)=\frac{2.01}{2.01 +2}\)
\(f(2.01)=\frac{2.01}{4.01}\)
\(f(2.01)=0.501247\)
When \(x = 2.001\)
\(f(x) = \frac{x}{x + 2}\)
\(f(2.001) = \frac{2.001}{2.001 +2}\)
\(f(2.001) = \frac{2.001}{4.001}\)
\(f(2.001) = 0.500125\)
When \(x = 2.0001\)
\(f(x) = \frac{x}{x + 2}\)
\(f(2.0001) = \frac{2.0001}{2.0001 + 2}\)
\(f(2.0001) = \frac{2.0001}{4.0001}\)
\(f(2.0001) = 0.500012\)
When \(x = 1.9\)
\(f(x) = \frac{x}{x + 2}\)
\(f(1.9) = \frac{1.9}{1.9 + 2}\)
\(f(1.9) = \frac{1.9}{3.9}\)
\(f(1.9) = 0.487179\)
When \(x = 1.95\)
\(f(x) = \frac{x}{x + 2}\)
\(f(1.95) = \frac{1.95}{1.95 + 2}\)
\(f(1.95) = \frac{1.95}{3.95}\)
\(f(1.95) = 0.493671\)

\(f(x) = \frac{x}{x + 2}\)
\(f(1.99) = \frac{1.99}{1.99 + 2}\)
\(f(1.99) = \frac{1.99}{3.99}\)
\(f(1.99) = 0.498747\)
\(f(x) = \frac{x}{x + 2}\)
When \(x = 1.999\)
\(f(x) = \frac{x}{x + 2}\)
\(f(1.999) = \frac{1.999}{1.999 + 2}\)

Find the 66th
term in the following
arithmetic sequence
-92, -85, -78, -71, ...
Answers
Answer:
The \(66\)th term is \(363\).
Step-by-step explanation:
To find the \(n\)th term, the formula is \(7n - 99\). Since we want to find the \(66\)th term, we can plug \(n\) for \(66\). So our expression is now \(7 \cdot 66 - 99 =\) \(66\)th term. Solving this we have
\(462 - 99 = 66\text{th term}\\363 = 66\text{th term}\\\). Therefore, the \(66\)th term is \(\boxed{363}\).
Answer:
a₆₆ = 363
Step-by-step explanation:
the nth term of an arithmetic sequence is
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 92 and d = a₂ - a₁ = - 85 - (- 92) = - 85 + 92 = 7 , then
a₆₆ = - 92 + (65 × 7)
= - 92 + 455

The best interpretation of the probability that the number landing face up will be less than 3 is \(\frac{1}{3}\).
For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is \(\frac{1}{3}\).
As per the given question a fair die with its faces numbered from 1 to 6 will be rolled.
Here we have to calculate the probability that the number landing face up will be less than 3.
The event of the number landing face up will be less than 3 is exhaustive, mutually exclusive, and independent face of a die = 6
(1, 2, 3, 4, 5, 6)
Favorable number of faces of a die = 2
(1, 2)
Since the number landing faces up will be less than 3.
Therefore the probability that the number landing face up will be less than 3

The long-run relative frequency of a number less than 3 landing face up is 2/3.
The best interpretation of the probability that the number landing face up will be less than 3 is that for many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 2/3. This can be expressed mathematically as P(x<3) = 2/3, where P(x) is the probability of the number landing face up being less than 3.
For a single roll of the die, the probability of a number less than 3 landing face up is 1/2. This is because there are three numbers (1,2,3) which are less than 3, and 6 possible outcomes. Therefore, the probability of any one of those three numbers landing face up is 3/6, or 1/2.
For multiple rolls of the die, the probability of a number less than 3 landing face up is the sum of the probabilities of each of those three numbers landing face up. This can be expressed mathematically as P(x<3) = (1/2) + (1/2) + (1/2), or 2/3.
Therefore, for many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 2/3.

To calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n, we will use several natural numbers to represent n.
For n= 1,
2n - 1 = 2(1) - 1 = 2 - 1 = 1
Hence, 1 = 1
For n = 2,
2n - 1 = 2(2) - 1 = 4 - 1 = 3
Hence, 1 + 3 = 4
For n = 3,
2n - 1 = 2(3) - 1 = 6 - 1 = 5
Hence, 1 + 3 + 5 = 9
For n = 4,
2n - 1 = 2(4) - 1 = 8 - 1 = 7
Hence, 1 + 3 + 5 + 7 = 16
For n = 5,
2n - 1 = 2(5) - 1 = 10 - 1 = 9
Hence, 1 + 3 + 5 + 7 + 9 = 25
For n = 6,
2n - 1 = 2(6) - 1 = 12 - 1 = 11
Hence, 1 + 3 + 5 + 7 + 9 + 11 = 36
For n = 7,
2n - 1 = 2(7) - 1 = 14 - 1 = 13
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49
For n = 8,
2n - 1 = 2(8) - 1 = 16 - 1 = 15
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
For n = 9,
2n - 1 = 2(9) - 1 = 18 - 1 = 17
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
For n = 10,
2n - 1 = 2(10) - 1 = 20 - 1 = 19
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100

Answer:
11Step-by-step explanation:
Use the triangle in the middle. It has interior angles:
F = 180 - 147 = 33E = 180 - 4xxUse the sum of the three interior angles and find the value of x:
33 + 180 - 4x + x = 18033 - 3x = 03x = 33x = 11Angle F and G are Colinear pairs
<F=180-147=33°Now we know
Sum of two interior angles=Exterior angle
\(\\ \sf\longmapsto 33+x=4x\)
\(\\ \sf\longmapsto 4x-x=33\)
\(\\ \sf\longmapsto 3x=33\)
\(\\ \sf\longmapsto x=\dfrac{33}{3}\)
\(\\ \sf\longmapsto x=11\)
What would the image below look like after a rotation of 909, centered 6. at the origin? D с C. 1 A A D. В. e A
Answers
during the rotaion with 90 degrees the coordinates are transform into
(x,y) change to (-y,x)
In the given graph:
The coordinates of A is (-3,0), T(-1,-1), C(-4,-3)
So, after the rotaion to 90 degree
\(\begin{gathered} (x,y)\rightarrow(-y,x) \\ A(-3,0)\rightarrow A^{\prime}(0,-3) \\ B(-1,-1)\rightarrow B^{\prime}(1,-1) \\ C(-4,-3)\rightarrow C^{\prime}(3,-4) \end{gathered}\)Plot them on the graph:
This graph is similar to the graph C
so, the image after rotaion to 90 degree is C
Answer: C)
