How to complete the table?

To do so, we just need to evaluate the functions in the given values. The functions are:

g(x) = 5^x

f(x) = 2 + 3x + 2x^2

Evaluating them we will get.

when x = 1

g(1) = 5^1 = 5

f(1) = 2 + 3*1 + 2*1^2 = 7

when x = 2

g(2) = 5^2 = 25

f(2) = 2 + 3*2 + 2*2^2 = 16

when x = 3

g(3) = 5^3 = 125

f(1) = 2 + 3*3 + 2*3^2 = 29

when x = 4

g(4) = 5^4 = 625

f(4) = 2 + 3*4 + 2*4^2 = 46

when x = 5

g(5) = 5^5 = 3,125

f(5) = 2 + 3*5 + 2*5^2 = 67

__________ refer to the probabilities of the states of nature after revising the prior probabilities based on sample information.

Answers

The probabilities of the states of nature after revising the prior probabilities based on sample information are called posterior probabilities.

The concept of posterior probabilities is fundamental in Bayesian statistics, which is a branch of statistics that deals with probability distributions of parameters based on prior knowledge and observed data. In Bayesian statistics, the prior probability represents the degree of belief in a hypothesis before new data is collected. The posterior probability, on the other hand, represents the updated degree of belief in the hypothesis after new data is collected.

The posterior probability is calculated using Bayes' theorem, which relates the conditional probabilities of the hypothesis and the data. The formula for Bayes' theorem is:

posterior probability = (prior probability x likelihood) / evid

The likelihood represents the probability of observing the data given the hypothesis, while the evidence is a normalizing constant that ensures the posterior probability integrates to one.

To run a one-proportion hypothesis test for Jerry using the One Proportion applet, we would need to enter sample size, hypothesized proportion and number of successes.

To run a one-proportion hypothesis test for Jerry using the One Proportion applet, we would need to enter the following values:

-The sample size (n) - the number of participants in Jerry's study.

-The number of successes (x) - the number of participants who showed a preference for the new product in Jerry's study.

-The hypothesized proportion (p0) - the proportion of participants who are expected to show a preference for the new product based on the null hypothesis. This value is typically set to the proportion stated in the null hypothesis.

The significance level (alpha) - the level of significance used to determine the critical value and p-value for the test. This value is typically set to 0.05.

Once these values are entered into the One Proportion applet, we can run the analysis and obtain the test statistic (z-score), the critical value, and the p-value. We can then compare the p-value to the significance level to determine whether to reject or fail to reject the null hypothesis.

An insurance company is insuring a person's coin collection worth $20,000 for an annual premium of $300. If the company figures that the probability of the collection being stolen is 0.002, what will be the insurance company's expected profit

Answers

The insurance company's expected profit from insuring this person's coin collection is $260.

The insurance company's expected profit can be calculated using the terms: coin collection value, annual premium, and probability of theft. In this case, the coin collection is worth $20,000, the annual premium is $300, and the probability of theft is 0.002.

To find the expected profit, we first need to determine the expected loss, which is the product of the coin collection value and the probability of theft: $20,000 x 0.002 = $40. This means that, on average, the company expects to pay out $40 per year for potential theft claims.

Next, we compare the expected loss to the annual premium. The insurance company collects $300 from the policyholder each year as the annual premium. To find the expected profit, we subtract the expected loss from the annual premium: $300 - $40 = $260.

Therefore, the insurance company's expected profit for insuring the coin collection is $260 per year. This calculation assumes that the probability of theft remains constant and does not account for other factors, such as administrative expenses or changes in the collection's value.

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the
line y = 14,
y=x, y = 13,x=0

Answers

Note that the volume of the solid is 5,132.32unit³

What is the justification for the above?

To find the volume of the solid generated by revolving the region about the line y=14, we can use the method of cylindrical shells.

 We integrate the surface area of each shell from 0 to 13, then multiply by the thickness of ech shell (d x), and finally add up all the shells.

The radius of each shell is given by the distance from the axis of rotation (y =14) to the function y = x, which is r  = 14 - x. The height of each shell is given by the function   y = 13 - x.

Therefore, the volume of the solid is stated as

V = ∫[0,13] 2πrh dx

V = ∫[0,13] 2π(14-x)(13-x) dx

V = 2π ∫[0,13] (182 - 27x + x²) dx

V = 2π [182x - (27/2)x² + (1/3)x³] [0,13]

V = 2π [(182(13) - (27/2)(13)² + (1/3)(13)³) - 0]

199. Binary Tree Right Side View
Given a binary tree, imagine yourself standing on the right side of it, return the values of the nodes you can see ordered from top to bottom.
For example:
Given the following binary tree,
1 <---
/ \
2 3 <---
\ \
5 4 <---
You should return [1, 3, 4].

Answers

The problem requires finding the values of the nodes on the right side of a binary tree, ordered from top to bottom. We can solve this problem by performing a level-order traversal of the binary tree and keeping track of the rightmost node at each level. We only add the rightmost node to the result list for each level.

To solve this problem, we can perform a level-order traversal of the binary tree and keep track of the rightmost node at each level. We can use a queue to traverse the tree level by level, starting with the root node. For each level, we only add the rightmost node to the result.

Here's the Python code to implement this approach:

```
from collections import deque

def rightSideView(root):
   if not root:
       return []
   
   result = []
   queue = deque([root])
   
   while queue:
       level_size = len(queue)
       
       for i in range(level_size):
           node = queue.popleft()
           
           # Only add the rightmost node to the result
           if i == level_size - 1:
               result.append(node.val)
           
           # Add the child nodes to the queue
           if node.left:
               queue.append(node.left)
           if node.right:
               queue.append(node.right)
   
   return result
```

We first handle the case where the root is None, in which case we return an empty list. We then initialize an empty list `result` to store the values of the rightmost nodes and a queue `queue` to perform the level-order traversal.

We begin by adding the root node to the queue. We then enter a loop that continues until the queue is empty. In each iteration of the loop, we first get the number of nodes in the current level by taking the length of the queue. We then iterate through the nodes in the current level and remove them from the queue using `popleft()`.

For each node, we check if it is the rightmost node in the current level (i.e., its index is equal to the level size minus one). If it is, we add its value to the result list. We then add the child nodes of the current node to the queue if they exist.

Finally, we return the result list containing the values of the rightmost nodes in the binary tree.

For example, for the binary tree given in the prompt, the function `rightSideView(root)` will return [1, 3, 4].

A sample contains 2/3 oz. of liquid. How many milliliters (mL) is this?

Answers

A sample containing 2/3 oz. of liquid is approximately 19.72 milliliters (mL).

To convert 2/3 oz. of liquid to milliliters (mL):
1. Identify the conversion factor: There are approximately 29.5735 mL in 1 ounce (oz).
2. Set up a proportion: To convert 2/3 oz. to mL, we need to multiply the given amount by the conversion factor.
  (2/3 oz.) x (29.5735 mL/1 oz.)
3. Cancel out the units: The "oz" units will cancel out, leaving us with mL.
  (2/3) x (29.5735 mL)


4. Multiply the fraction by the conversion factor: Now, multiply 2/3 by 29.5735.
  (2/3) x 29.5735 = 19.7157
5. Round the result: We'll round the result to two decimal places to make it easier to understand.
  19.7157 mL = 19.72 mL
So, a sample containing 2/3 oz. of liquid is approximately 19.72 milliliters.

Car A went 60 km in 5/6 of an hour, while car B went 54 km in 2/3 of an hour.Which car was faster? How many times faster?

Answers

Car B travels faster than Car A.

We have,

Car A went 60 km in 5/6 of an hour, while car B went 54 km in 2/3 of an hour.

Car A:

Speed = Distance/ time

speed = 60/ (5/6)

speed = 60x 6/5

speed = 72 Km/h

Car B:

Speed = Distance/ time

speed = 54/ (2/3)

speed = 54 x 3/2

speed = 81 Km/h

Thus, Car B travels faster than Car A.
