A card is drawn from a standard 52-card deck. If the card is a king, you win $20; otherwise, you lose $1. What is the expected value of the game?
Let X be the random variable for the amount won on a single play of this game.
Answers
If X is a radom variable for amount you win, Then the excepted value of game or expected income i.e E(X) is 8/13.
What is Expected Income ?Expected Income is the result of multiplying your income by the probability of earning it. This expected revenue can be subtracted by the expected cost to get the expected profit.
Mathematically, E(X) = X₁p₁ + X₂p₂ + ---+ Xₙpₙ
where Xᵢ are observation and pᵢ probability of Xᵢ.
We have given that,
Total number of cards in standard card deck = 52
i.e total possible outcomes = 52
One card is drawn from deck.
Total number of king cards in 52-card deck = 4
Favourable outcomes that drawn card is king = 4
Probability of getting a king card , p = 4/52 = 1/13
Probability of not getting a king ,q = 1 - p
= 1 - 1/13 = 12/13
let X be the amount you win . You win $20 if a king is drawn and lose $1 if king is not drawn . So, probability distribution is
Xᵢ pᵢ
$20 1/13
-$1 12/13
So, E(X) = ∑ Xᵢpᵢ = 20× 1/13 + (-1)× 12/13 = 20/13 - 1/13 = 8/13
Hence, required excepted value is 8/13.

Recall the binomial theorem.
\((a+b)^n = \displaystyle \sum_{k=0}^n \binom nk a^{n-k} b^k\)
1. The binomial expansion of \(\left(1+\frac x3\right)^7\) is
\(\left(1 + \dfrac x3\right)^7 = \displaystyle\sum_{k=0}^7 \binom 7k 1^{7-k} \left(\frac x3\right)^k = \sum_{k=0}^7 \binom 7k \frac{x^k}{3^k}\)
Observe that
\(k = 1 \implies \dbinom 71 \left(\dfrac x3\right)^1 = \dfrac73 x\)
\(k = 2 \implies \dbinom 72 \left(\dfrac x3\right)^2 = \dfrac73 x^2\)
When we multiply these by \(8-9x\),
• \(8\) and \(\frac73 x^2\) combine to make \(\frac{56}3 x^2\)
• \(-9x\) and \(\frac73 x\) combine to make \(-\frac{63}3 x^2 = -21x^2\)
and the sum of these terms is
\(\dfrac{56}3 x^2 - 21x^2 = \boxed{-\dfrac73 x^2}\)
2. The binomial expansion is
\(\left(2a - \dfrac b2\right)^8 = \displaystyle \sum_{k=0}^8 \binom 8k (2a)^{8-k} \left(-\frac b2\right)^k = \sum_{k=0}^8 \binom 8k 2^{8-2k} a^{8-k} b^k\)
We get the \(a^6b^2\) term when \(k=2\) :
\(k=2 \implies \dbinom 82 2^{8-2\cdot2} a^{8-2} b^2 = 28 \cdot2^4 a^6 b^2 = \boxed{448} \, a^6b^2\)
These are large nets used for fishing kept upright by weights at the bottom and floats and the top and allowed to move with the tide.
Answers
The large nets you're referring to are called "drift nets." Drift nets are kept upright by weights at the bottom and floats at the top, allowing them to move with the tide and efficiently catch fish in the process.
They are designed to float at the surface of the water and drift along with the tide, capturing fish as they pass through the netting. Drift nets are kept upright by weights at the bottom and floats at the top, which allows them to move with the current and cover a large area of water. These types of nets are often used in commercial fishing operations, but they have also been criticized for being environmentally destructive, as they can catch unintended species and result in large amounts of bycatch. Overall, drift nets are a complicated fishing technique with a long history, and their use is still debated by fishermen, environmentalists, and policymakers.

Answers
The largest interval on which the solution is defined is (-∞, -1) ∪ (-1, ∞). The interval notation for the largest interval is (-∞, -1) U (-1, ∞).
What is the initial-value problem?An initial-value problem is a type of boundary-value problem in mathematics, particularly in the field of differential equations.
The given initial-value problem is a separable differential equation, which can be written as:
dy/dt = -2(t + 1)y²
Integrating both sides, we get:
(1/y) = t² + 2t + C
where C is the constant of integration.
Since we have an initial condition, we can use it to find the value of C:
y(0) = -1/15
C = -1/15
Solving for C, we get:
C = -1/15
So, the solution to the differential equation is:
(1/y) = t² + 2t -1/15
y = 1 / (t² + 2t -1/15)
The solution is defined for all t ≠ -1, since y = 0 is not defined. So, the largest interval on which the solution is defined is (-∞, -1) ∪ (-1, ∞). The interval notation for the largest interval is (-∞, -1) U (-1, ∞).

Don Swiffer earns $9.75 per hour as a clerk. He starts work Mondaythrough Friday morning at 8:00 AM. He takes a half hour lunch break everyday. If he finishes work at 3:00 PM Monday through Thursday and leaveswork at 4:00 PM on Friday. What was his total pay for the week?
Answers
Answer: $326.625
Explanation:
The infromation that we have is:
Payment per hour: p = $9.75 (I will identify the payment per hour as "p").
He worls from 8:00 am until 3 pm from monday through thursday, this means that he works 7 hours on those days. But since he takes a half hour lunch break, we take half an hour from the 7 hours:
\(7-0.5=6.5\)Each from monday trough thursday that he works, he does it for 6.5 hours.
Thus, the total amount of hours for this four days of the week is:
\(4\times6.5=26\)On Friday he works from 8:00 am to 4:00pm, that is 8 hours, as in the previus days, we substract half hour for his break:
\(8-0.5=7.5\)So the total amount of hours that he works in the week is the sum of the 26 hours that he works from monday through thursday, plus the 7.5 hours that he works on friday:
\(h=26+7.5=33.5\)h represents the amount of hours that he works in a week.
His total pay for the week "T" is:
\(T=h\times p\)The product between the number of hours and the payment per hour:

form a quadratic polynomial whose zeroes are 3+√5/2 nd 3-√5/2?
Answers
The quadratic polynomial is x² - 6x + 31/4
What is a quadratic polynomial?A quadratic polynomial is a polynomial in which the highest power of the unknown is 2.
To form a quadratic polynomial whose zeroes are 3 + √5/2 and 3 - √5/2, we proceed as follows.
Since the zeroes are
x = 3 + √5/2 and x = 3 - √5/2,Then its factors are
x - (3 + √5/2) = (x - 3) - √5/2 and x - (3 - √5/2) = (x - 3) + √5/2So, to get the quadratic polynomial p(x), we multiply the factors together.
So, we have that
p(x) = [(x - 3) - √5/2][(x - 3) + √5/2]
= (x - 3)² - (√5/2)²
= x² - 6x + 9 - 5/4
= x² - 6x + (36 - 5)/4
= x² - 6x + 31/4
So, the polynomial is x² - 6x + 31/4

Answers
The population standard deviation is known to be $11. construct the 98% confidence interval, then the 98% confidence interval for mean (a , b) = ( $16.8 , $16.3 )
A confidence interval is a range of values that describes the uncertainty surrounding an estimate.
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
CI = \(x\) ± z \(\frac{r}{\sqrt{n} }\) (Equation-1)
Where,
CI = Confidence interval
x = sample mean
z = Confidence level value
r = sample standard deviation
n = sample size
Given that,
Mean x = $16.6
Standard deviation r = $11
Number of samples n = 7472
Confidence interval = 98%
z(at 98% confidence) = 2.33
Substituting the values we have equation-1,
= $16.6 ± 2.33 ( \(\frac{11}{\sqrt{7472} }\) )
= $16.6 ± 2.33 ( $\(\frac{11}{86.44}\) )
= $16.6 ± 2.33 ( $ 0.127 )
= $16.6 ± $0.295
= $16.6 + $0.295 , $16.6 - $0.295
= ( $16.8 , $16.3 )
Therefore,
The population standard deviation is known to be $11. construct the 98% confidence interval, then the 98% confidence interval for mean (a , b) = ( $16.8 , $16.3 )
