Brian is expected to roll a number greater than 4, 4 times
How to determine the expected row?In a fair die, we have:
Faces = 6
Faces greater than 4 = 2 i.e. 5 and 6
So, the probability to roll a number greater than 4 is:
p = 2/6
When the dice is rolled 12 times, the expected value is:
Expected = 2/6 * 12
Evaluate
Expected = 4
Hence, Brian is expected to roll a number greater than 4, 4 times

Answer:
1). g(x) = \(5^{3x}\)
2). g(x) = \(\frac{1}{3}5^{x}\)
3). g(x) = \(3(5)^{x}\)
4). g(x) = \(5^{\frac{1}{3}x}\)
Step-by-step explanation:
Parent function f(x) = \(a^{x}\) when transformed in the form of \(g(x)=h(a^{\frac{x}{k} })\)
1). If h > 1, function is vertically stretched.
2). If 0 < h < 1, function is vertically compressed.
3). If k > 1, function is horizontally compressed.
4). If 0 < k < 1, function is horizontally stretched.
Parent function of the given functions in the question is f(x) = \(5^{x}\)
g(x)= \(\frac{1}{3}(5^{x})\), parent function is vertically compressed by a factor of \(\frac{1}{3}\).
g(x) = \(5^{3x}\), parent function 'f' is horizontally stretched by a factor of 3.
g(x) = \(5^{\frac{x}{3}}\), parent function 'f' is horizontally compressed by a factor of \(\frac{1}{3}\).
g(x) = \(3(5^{x})\), parent function 'f' is vertically stretched by a factor of 3.
Jonathan is rolling to dice and needs to roll and 11 to win the game he is playing what is the probability that Jonathan wins the game
Answer:
1 / 18
Step-by-step explanation:
In a roll of two dice :
Number of faces on a dice = 6
Total sample space for 2 6-sided dice = (number of faces)^Number of dice = 6^2 = 36
Total possible outcomes = 36
Required outcome = sum of 11
11 = {(5,6) ; (6, 5)}) = 2 possibilities
Probability = required outcome / Total possible outcomes
P(obtaining a sum of 11) = 2 / 36 = 1/18

The number of lightning strikes in a year at the top of a particular mountain has a Poisson distribution with a mean of 2.1. Find the probability that in a randomly selected year, the number of lightning strikes is 4
The probability that in a randomly selected year, the number of lightning strikes is 4, is 0.098.
What is Poisson distribution?
The Poisson distribution refers to a probability distribution expressing the probability of a specific number of events occurring in a fixed interval of time, if these events occur with a known constant mean rate and independent of the occurrence of the last event.
P(E) = Probability of occurrence of E in a fixed interval 'x', with constant mean = \(\frac{e^{-mean}. mean^{x}}{x!}\)
Step-by-step explanation:
Let A be the number of lightning strikes in a year at the top of particular mountain. Here, A follows Poisson distribution with mean = 2.1.
According to the question, x = 4, mean = 2.1
Thus, putting it in the formula for Poisson distribution, we get:
P(A) = \(\frac{e^{-2.1}(2.1)^{4} }{4!}\) = \(\frac{0.122(19.44)}{24}\) = 0.098
=> P(A) = 0.098
Hence, the probability that in a randomly selected year, the number of lightning strikes is 4, is 0.098.

A vase contains 60 marbles, all of which are red or orange. if the ratio of red marbles to orange ones is 1:5, what is the total number of red marbles in the vase?
The total number of red marbles in the vase are 10.
What is the ratio?A ratio is described as a comparison between two amounts with the same unit to determine the amount of 1 quantity is contained in the other. Ratios are divided into two sorts.
The first is a part-to-part ratio, and the second is a part-to-whole ratio. The part-to-part ratio expresses the relationship between 2 separate entities or groupings.
Now, according to the question;
Let 'x' be the red marbles in the vase.
Let 'y' be the orange marbles in the vase.
The total number of marbles in the vase are 60
x + y = 60 (equation 1)
The ratio of red marbles to orange ones is 1:5.
Thus, x/y = 1/5
cross multiplying;
5x = y
or y = 5x
substitute the value of y in equation 1;
x + y = 60 (equation 1)
x + 5x = 60
6x = 60
x = 10 (red marbles)
Thus, the number of red marbles in the vase are 10.

Consider the following functions. f₁(x) = x, f₂(x) = x², f3(x) = 2x - 7x² g(x) = c₁f₁(x) + C₂F₂(x) + C3f3(x) Solve for C₁, C₂, and c3 so that g(x) = 0 on the interval (-[infinity], [infinity]). If a nontrivial solution exists, enter the trivial solution (0, 0, 0}.) {C₁₁ C₁₁ C3} = { ______ }
To solve for C₁, C₂, and C₃ such that g(x) = 0 on the interval (-∞, ∞), we need to find the coefficients that make the linear combination of the functions f₁(x), f₂(x), and f₃(x) equal to zero.
We have the following functions:
f₁(x) = x
f₂(x) = x²
f₃(x) = 2x - 7x²
And we need to find C₁, C₂, and C₃ such that:
g(x) = C₁f₁(x) + C₂f₂(x) + C₃f₃(x) = 0
Substituting the given functions, we have:
C₁x + C₂x² + C₃(2x - 7x²) = 0
To solve for C₁, C₂, and C₃, we can equate the coefficients of like terms. Let's match the coefficients of x, x², and the constant term separately:
For the coefficient of x:
C₁ + 2C₃ = 0 ...(1)
For the coefficient of x²:
C₂ - 7C₃ = 0 ...(2)
For the constant term:
0 = 0 ...(3)
From equation (3), we can see that the constant term doesn't impose any constraints on the coefficients.
Now, we solve equations (1) and (2) simultaneously to find the values of C₁, C₂, and C₃:
From equation (2), we have:
C₂ = 7C₃
Substituting this into equation (1), we get:
C₁ + 2C₃ = 0
Since we have two variables and one equation, we can't determine unique values for C₁, C₂, and C₃. Instead, we can express them in terms of a single parameter, let's say C₃:
C₁ = -2C₃
C₂ = 7C₃
So, the solution for C₁, C₂, and C₃ in terms of C₃ is:
C₁ = -2C₃
C₂ = 7C₃
C₃ = C₃
In summary, the solution for C₁, C₂, and C₃ such that g(x) = 0 on the interval (-∞, ∞) is given by:
C₁ = -2C₃
C₂ = 7C₃
C₃ = C₃
Note that the parameter C₃ can take any real value, including zero, resulting in the trivial solution (0, 0, 0).

To find:
The cost of each puzzle.
Solution:
Let x be the cost of a puzzle and y be the cost of piece of candy.
Kendra charges $8.00 for two puzzles and a piece of candy.
\(2x+y=8\) ...(i)
She charges $4.50 for one puzzle and a piece of candy.
\(x+y=4.50\) ...(ii)
Subtracting (ii) from (i), we get
\(2x+y-(x+y)=8-4.50\)
\(2x+y-x-y=3.50\)
\(x=3.50\)
The cost of puzzle is $3.50. Therefore, the correct option is A.
1 points You have purchased a put option on ABC common stock for 53 per contract. The option has an exerche price of 558 What is your net produce this options stock price is $46 at expiration?
If an investor bought a put option on ABC common stock for $53 per contract with an exercise price of $558 and the stock price at expiration is $46, the net profit would be $459.
To calculate the net profit on a put option, we need to consider the initial cost of the option and the difference between the exercise price and the stock price at expiration.
Given:
Put option purchase price: $53 per contract
Exercise price: $558
Stock price at expiration: $46
Since the stock price at expiration ($46) is lower than the exercise price ($558) in the case of a put option, the option is in the money. The option holder has the right to sell the stock at a higher price than its market value.
To calculate the net profit, we need to consider the initial cost and the difference in stock price:
Net Profit = [(Exercise Price - Stock Price) - Option Cost] * Number of Contracts
In this case:
Net Profit = [(558 - 46) - 53] * 1 (assuming one contract)
= (512 - 53) * 1
= $459
Therefore, the net profit from this put option, assuming one contract, would be $459.
Conclusion: If the stock price at expiration is $46 and an investor purchased a put option on ABC common stock for $53 per contract with an exercise price of $558, the net profit would be $459. This implies that the investor would have a positive return on their investment, as the option is in the money.

You perform a Chi-Square test and obtain a p-value lower than 0.01. What does that mean?
Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.
If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.
The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.
In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.
