What is the probability that X1 is less than 2 and X2 is greater than 1?To find P(X1 < 2, X2 > 1), we need to evaluate the probability density function within the given range. The function indicates that the joint behavior of X1 and X2 follows a specific pattern. Understanding this probability helps in analyzing customer waiting and service times at the fast-food outlet.
The marginal density function for X can be obtained by integrating the joint probability density function with respect to X2.

TRUE/FALSE. in a poisson distribution, the probability of success may vary from trial to trial.
Answers
The statement is false because in a Poisson distribution, the probability of success does not vary from trial to trial.
The Poisson distribution is a discrete probability distribution that describes the number of times an event occurs in a fixed time interval or spatial region, given the average rate of occurrence and assuming that the events are independent and random.
The Poisson distribution has only one parameter, λ, which represents the average rate of occurrence of the event.
The probability of observing k events in the interval is given by the Poisson probability mass function:
P(k) = (e^(-λ) * λ^k) / k!
where e is the base of the natural logarithm, and k is a non-negative integer.
The Poisson distribution assumes that the probability of observing an event at any given point in time or space is constant, and that the events are independent of each other.

Answers
In order to calculate the z-scores for the given Confidence Interval (CI) levels, we need to use the Z-table. It is also known as the standard normal distribution table. Here are the z-scores for the given Confidence Interval levels:1. 68% CI: The confidence interval corresponds to 1 standard deviation on each side of the mean.
Thus, the z-score for the 68% \(CI is ±1.00.2. 85% CI\): The confidence interval corresponds to 1.44 standard deviations on each side of the mean.
We can calculate the z-score using the following formula:\(z = invNorm((1 + 0.85)/2)z = invNorm(0.925)z ≈ ±1.44\)Note that invNorm is the inverse normal cumulative distribution function (CDF) which tells us the z-score given a certain area under the curve.3. 99% CI: The confidence interval corresponds to 2.58 standard deviations on each side of the mean. We can calculate the z-score using the following formula:\(z = invNorm((1 + 0.99)/2)z = invNorm(0.995)z ≈ ±2.58\)
Note that in general, to calculate the z-score for a CI level of (100 - α)% where α is the level of significance, we can use the following formula:\(z = invNorm((1 + α/100)/2)\) Hope this helps!

B. Critical value
C. Level of significance
D. Sample proportion
Answers
The p-value is the probability of getting a test statistic at least as extreme as the one representing the sample data, assuming that the null hypothesis is true.
The p-value is the probability of obtaining a test statistic that is as extreme as, or more extreme than, the one observed from the sample data, assuming that the null hypothesis is true. It is a measure of the evidence against the null hypothesis provided by the data. The p-value is used in hypothesis testing to make decisions about the null hypothesis. If the p-value is less than the predetermined level of significance (alpha), typically 0.05, it suggests that the observed data is unlikely to occur by chance alone under the null hypothesis. This leads to rejecting the null hypothesis in favor of the alternative hypothesis. On the other hand, if the p-value is greater than the significance level, there is insufficient evidence to reject the null hypothesis.For more questions on probability :

You have a choice to invest in one of three different college funds to save up for college. You need to save at least $14,000 for your first year. In which of the three accounts do you choose to invest your money given that you have $10,000 to invest and you would like to accrue as much interest as possible?
Answers
Answer: C) You choose account #2
===================================================
Explanation:
Let's compute the final balance for account 1.
We'll use the compound interest formula
A = P*(1+r/n)^(n*t)
where,
P = principal or amount depositedr = decimal form of the annual interest raten = number of times we compound the interest per yeart = number of yearswhere in this case
P = 10,000r = 0.035 n = 4 t = 10So with all that in mind, we get
A = P*(1+r/n)^(n*t)
A = 10,000*(1+0.035/4)^(4*10)
A = 14,169.0883793113
A = 14,169.09
Account #1 gets us $14,169.09 which is over our goal of $14,000
--------------------------
Let's repeat this idea for account 3. I'll get back to account 2 in the next section.
For account 3, we have these inputs
P = 10,000r = 0.032n = 1t = 10leading to...
A = P*(1+r/n)^(n*t)
A = 10,000*(1+0.032/1)^(1*10)
A = 13,702.4104633564
A = 13,702.41
This isn't larger than 14,000. So we cannot use account 3. The interest rate is too small and needs to be bumped up.
--------------------------
Now let's compute account 2. We'll use the continuously compounded interest formula which is
A = P*e^(rt)
The P, r and t are the same as before. The 'e' is a constant and it's roughly e = 2.718... similar to how pi = 3.14... approximately.
I recommend using the calculator's stored value of 'e' to get as much accuracy as possible.
So,
A = P*e^(rt)
A = 10,000*e^(0.036*10)
A = 14,333.2941456052
A = 14,333.29
This exceeds 14,000 so we can use this account.
Comparing this to account 1's value (14,169.09), we can see that account 2 gets us the most money over the 10 year time period. Not only does account 2 have the higher interest rate, but it also has an infinitely higher compounding frequency as well. These two factors help contribute as to why account 2 beats out account 1.
This is why we should go for account 2.

How to Convert Decimal to Octal?
Answers
Answer:
Step-by-step explanation:
We divide the number by 8 and write the remainder in reverse order to get the equivalent octal number.
Answer:
Let's write down the base of each one:
- Decimal is base 10 (0 to 9)
- Octal is base 8 (0 to 7)
So, if we want to convert decimal to octal, we need to divide the decimal number by 8 and hold onto the remainder.
Then once your quotient becomes 0, from the last remainder to the first, write your numbers.
For example here is 437 base 10.
437 / 8 = 54 R 5
54 / 8 = 6 R 6
6 / 8 = 0 R 6
So, the answer is 665 base 8.

It should be noted that z^4 will be -32 in rectangular form.
How to calculate the valueBased on the information, z = r(cos θ + i sin θ), and provided positive integer n, then it is implied that:
z^n = r^n (cos nθ + i sin nθ)
In this instance, we need to solve for z^4 in rectangular form when z = -2 - 2i. Firstly, we must calculate |z| and arg(z):
|z| = √((-2)^2 + (-2)^2) = 2√2
arg(z) = arctan(-2/-2) = π/4
Leveraging De Moivre's theorem, we can effectively deduce the value of z^4 as:
z^4 = (2√2)^4 (cos (4π/4) + i sin (4π/4))
= 32 (cos π + i sin π)
= -32
