Let consider a biased coin that has a probability í = 3/4 of coming up heads. If I pay you $1 if it comes up heads and $2 if it comes up tails. Let í be the number of dollars I pay you, which is a random variable. What is the expected value of í when the biased is flipped once?
The probability of heads is 3/4, and the probability of tails is 1/4. Let í be the number of dollars that you receive, which is a random variable. If it comes up heads, you will receive $1, and if it comes up tails, you will receive $2.
Thus, the possible values of í are 1 and 2.The expected value of í is given by the formula below:
\(E(i) = \sum_{i=1}^n x_i P_i\)
Where xi is the ith possible value of í, and Pi is the probability of xi. The expected value of í is given by the formula below:
\(E(i) = \sum_{i=1}^n x_i P_i\)
For this example, the possible values of í are 1 and 2. The probability of heads is 3/4, and the probability of tails is 1/4. Therefore, we can calculate the expected value of í as follows:
\(E(i) = (1) \cdot \frac{3}{4} + (2) \cdot \frac{1}{4}\)
\(= \frac{3}{4} + \frac{2}{4}\)
\(= \frac{5}{4}\)
Thus, the expected value of í when the biased coin is flipped once is $1.25.

right rectangular prism calc: find w, l=n/a, h=n/a, v=n/a
The value of width 'w' of rectangular prism with l = n/a, h = n/a, v = n/a is given by, w = a/n.
We know that the volume of rectangular prism with length L and width W and Height H is given by,
V = L*W*H
Given that the Height of the rectangular prism, h = n/a
Length of the rectangular prism, l = n/a
Volume of the rectangular prism, v = n/a
let the width of the rectangular prism be 'w'.
So from the volume formula we get,
v = lwh
n/a = (n/a)*w*(n/a)
n/a = (n/a)²*w
w = (n/a)/(n/a)² = (n/a)*(a/n)² = a/n
Hence the value of w is a/n.

Alicia and sarah are at the supermarket. Alicia wants to get peanuts from the bulk food bins and Sarah wants to get almonds. The almonds cost $5.50 per pound and the peanuts cost $2.50 per pound. Together they buy 1.6 pounds of nuts. If the total cost is $6.75, how much did each girl get?
Answer:
Alicia gets $2.50*0.91= $2.275 Sarah gets $5.50 *0.68=$3.74Step-by-step explanation:
let the almond be x pounds
and the peanuts be y pounds
so
x+y=1.6--------1
5.5x+2.5y=6.75---2
let us multiply both eqn 1 by 5.5 to to eleminate x
and subtract eqn 2 from the new eqn
5.5x+5.5y=8.8-----3
-5.5x+2.5y=6.75---2
0+3x=2.05
divide both sides by 3 we have
x=2.05/3
x=0.68 pound
put x=0.68 in eqn 1 we have
0.68+y=1.6
y=1.6-0.68
y=0.91 pounds
Alicia gets $2.50*0.91= $2.275
Sarah gets $5.50 *0.68=$3.74
The measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle. Find the measure of each acute angle.
The measure of each of the acute angles of the right triangle is 32° and 58°.
A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).
Let x = measure of one of the acute angles
If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then
measure of the other acute angle = 2x - 6
The sum of all the angles of any triangle is equal to 180°. Hence,
90° + x + 2x - 6 = 180°
Solve for the value of x.
3x = 96
x = 32
Solve for the measure of the other acute angle.
2x - 6 = 2(32) - 6 = 58
Hence, the two angles are 32° and 58°.

Aster corporation accepted a $20,000, 9 percent 120-day note dated august 25 from lee company in settlement of a past bill. On October 25, Aster Corporation decided to discount the note at a discount of 8 percent. The proceeds to Aster Corporation are (blank)
Answer:
$20, 533.33
Step-by-step explanation:
From the question, we are given the following values
Principal = $20000
Rate = 8% = 0.08
Time( in years) = 120days = 4 months = 4/12 years = 1/3 years
Interest = Principal × Rate × Time
Interest = 20,000 × 0.08× (1/4)
Interest = $533.33
Hence, the proceeds to Aster Corporation are
$20000 + $533.33
= $20,533.33

Manewering the Middle 110
The sum will be 46 which is the nearest combinational value that could be deduced from the digits 1, 2, 3, and 4.
Let's check all the combinations which can be possibly used,
34 + 21 = 46, which is 4 numbers less than 50 so far the nearest.
43 + 12 = 55, which is 5 numbers more than 50.
32 + 41 = 73, which is 23 numbers more than 50.
32 + 14 = 46, which is 4 numbers less than 50 so far the nearest.
23 + 41 = 64, which is 14 numbers more than 50.
So the two combinations are deduced after permutation and a combination of numbers that are 3 and 4 + 2 and 1 and another is 3 and 2 + 1 and 4.

dx 8. Find the Maclaurin series for the function f(x)=ln(1+x) using the definition of a "Maclaurin series" and find the associated radius of convergence.
The radius of convergence for the Maclaurin series of f(x) is determined by the convergence of the logarithm function. In this case, the radius of convergence is 1, as ln(1+x) is defined for x within the interval (-1, 1].
To find a series representation for the definite integral ∫₀¹ x * \(e^{(x-1)}\) dx, we can make use of the fact that \(e^x\) = ∑(n=0 to ∞) (x^n / n!) and integrate the series term by term.
Let's start by rewriting the integral with the series representation:
∫₀¹ x * \(e^{(x-1)}\) dx
= ∫₀¹ x * \(e^x * e^{(-1)}\) dx
= e^(-1) ∫₀¹ x *\(e^x\) dx
Now, we substitute \(e^x\) with its series representation:
e^(-1) ∫₀¹ x * ∑(n=0 to ∞) (\(x^n\) / n!) dx
We can interchange the order of summation and integration since the series converges uniformly on the interval [0, 1]:
\(e^{(-1)}\) * ∑(n=0 to ∞) ∫₀¹ \((x^{(n+1)}\) / n!) dx
Now, let's evaluate the integral:
\(e^{(-1)}\) * ∑(n=0 to ∞) [x^(n+2) / ((n+1) * n!)] | from 0 to 1
Evaluating the definite integral at the limits gives us:
e^(-1) * ∑(n=0 to ∞) [1 / ((n+1) * n!)]
= e^(-1) * ∑(n=0 to ∞) [1 / (n+1)!]
This series representation for the definite integral ∫₀¹ x * e^(x-1) dx is e^(-1) times the series ∑(n=0 to ∞) [1 / (n+1)!].
Now, let's move on to finding the Maclaurin series for the function f(x) = ln(1+x) using the definition of a Maclaurin series and determining the associated radius of convergence.
The Maclaurin series for f(x) = ln(1+x) can be obtained by repeatedly taking derivatives of f(x) and evaluating them at x = 0.
Let's start by finding the first few derivatives of f(x):
f(x) = ln(1+x)
f'(x) = 1 / (1+x)
f''(x) = -1 / (1+x)^2
f'''(x) = 2 / (1+x)^3
f''''(x) = -6 / (1+x)^4
We can observe a pattern in the derivatives:
\(f^{(n)}(x) = (-1)^(n-1) * (n-1)! / (1+x)^n\)
Now, let's evaluate these derivatives at x = 0:
f(0) = ln(1+0) = ln(1) = 0
f'(0) = 1 / (1+0) = 1
f''(0) = -1 / (\(1+0)^2\) = -1
f'''(0) = 2 /\((1+0)^3\) = 2
f''''(0) = -6 / \((1+0)^4\) = -6
We can see that the terms with odd powers of x evaluate to 0 at x = 0, so we can ignore them.
The Maclaurin series for f(x) = ln(1+x) becomes:
\(f(x) = 0 + 1*x - 1*x^2/2! + 2*x^3/3! - 6*x^4/\)4! + ...
Simplifying, we get:
\(f(x) = x - x^2/2 + x^3/3 - x^4/4 + ...\)

On a recent trip, Jan traveled 260 miles using 8 gallons of gas. What was the car's miles per gallon for this trip? Kilometers per liter? (show all of your calculations and work.)
To calculate the car's miles per gallon (mpg) for this trip, we divide the number of miles traveled by the number of gallons of gas used:
mpg = miles traveled / gallons of gas used mpg = 260 miles / 8 gallons = 32.5 mpg
We have to convert the miles per kilometer in order find the kilometer per litre. One mile is nealry equal to 1.609 kilometers, so,260 miles * 1.609 km/mile = 420.94 km
Next, the number of liters of gas is devided by the number of kilometers kpl = kilometers traveled / liters of gas used kpl = 420.94 km / 8 liters = 52.62 kpl
So, the car's miles per gallon for the trip is 32.5 mpg, and the equivalent kilometers per liter is 52.62 kpl.

how many odd numbers are there with middle digit 5 and no digit repeated between 20,000 and 69,999?
There are 252 odd numbers with the middle digit as 5 and no repeated digits between 20,000 and 69,999.
To determine the number of odd numbers with the middle digit as 5 and no repeated digits between 20,000 and 69,999, we need to consider the possible combinations for the remaining digits.
Since the middle digit is fixed as 5, we have three remaining digits to consider: the thousands digit, hundreds digit, and units digit.
Thousands Digit:
The thousands digit cannot be 0, 5 (as it is the middle digit), or 6 (to stay within the given range). So, we have 7 possible options: 2, 3, 4, 7, 8, and 9.
Hundreds Digit:
The hundreds digit can be any digit from 0 to 9, excluding the already used digits in the thousands and middle positions. So, we have 9 possible options.
Units Digit:
The units digit must be an odd number, excluding 5 (as it is the middle digit) and any digit already used in the thousands and hundreds positions. So, we have 4 possible options: 1, 3, 7, and 9.
By multiplying the number of options for each digit, we obtain the total number of odd numbers meeting the given conditions:
7 (thousands) * 9 (hundreds) * 4 (units) = 252

To simplify 3(w+11) /6w, we can first simplify the numerator by distributing the 3:
3(w+11) = 3w + 33
Now we have:
(3w + 33) / 6w
We can further simplify by factoring out a 3 from the numerator:
3(w + 11) = 3 * 1(w + 11)
So we have:
(3 * 1(w + 11)) / 6w
The 3's cancel out, leaving:
(w + 11) / 2w
Therefore, the fully simplified expression is (w + 11) / 2w.
