(1) The signs of coefficients for travel times and costs in each utility function can provide insights into the relationship between these variables and the mode choice. In the utility function for transit service (UT), the coefficient for travel time using transit (tt) is -5.4. This negative sign indicates that as travel time using transit increases, the utility of choosing transit decreases. Similarly, in the utility function for driving alone (UD), the coefficient for travel time using driving (td) is 5.4. This positive sign suggests that as travel time using driving increases, the utility of choosing driving alone also increases.

For costs, the coefficient for cost using transit service (CT) in the utility function for transit service (UT) is 0.75. This positive sign indicates that as the cost of using transit service increases, the utility of choosing transit decreases. In the utility function for driving alone (UD), the coefficient for cost using driving (CD) is -0.95. This negative sign suggests that as the cost of driving alone increases, the utility of choosing driving alone decreases.

(2) The signs of the coefficients of frequency of transit service (ft) and average delays due to congestion in the downtown area (dp) can also provide insights into their impact on mode choice. In the utility function for transit service (UT), the coefficient for frequency of transit service (ft) is 1.11. This positive sign indicates that as the frequency of transit service increases, the utility of choosing transit also increases. It suggests that individuals are more likely to choose transit when it is more readily available.

In the utility function for driving alone (UD), the coefficient for average delays due to congestion in the downtown area (dp) is not mentioned in the given information. Therefore, we cannot determine its impact or sign. It is important to note that the utility function for driving alone (UD) should be checked for this coefficient to assess its impact on mode choice.

(3) Two additional attributes that may impact mode choice in the described scenario could be environmental friendliness and parking availability. These attributes should be placed in the utility function for driving alone (UD).

For the attribute of environmental friendliness, a negative sign should be assigned to its coefficient. This indicates that as the environmental friendliness of driving alone increases, the utility of choosing driving alone decreases. This reflects a preference for modes that have less negative impact on the environment.

For the attribute of parking availability, a positive sign should be assigned to its coefficient. This suggests that as parking availability increases, the utility of choosing driving alone also increases. This reflects the convenience of finding parking spaces, which enhances the attractiveness of driving alone.

The two cases weigh 102,100 decigrams together.

First, we need to convert dekagrams to decigrams, since the question asks for the weight in decigrams.

1 dekagram = 10 grams

1 gram = 10 decigrams

Therefore, 1 dekagram = 100 decigrams

Now, let's calculate the weight of the two cases in decigrams:

Weight of tomato cans case = 563 dekagrams x 100 decigrams/dekagram = 56,300 decigrams

Weight of soup cans case = 458 dekagrams x 100 decigrams/dekagram = 45,800 decigrams

The weight of the two cases together is the sum of the two weights:

Total weight = 56,300 decigrams + 45,800 decigrams = 102,100 decigrams

Therefore, the two cases together weigh 102,100 decigrams.

To solve this problem, we need to first convert the weight of the two cases from dekagrams to decigrams so we can add them together.

1 dekagram = 10 grams

1 gram = 10 decigrams

So,

563 dekagrams = 5630 grams

5630 grams = 56300 decigrams

and

458 dekagrams = 4580 grams

4580 grams = 45800 decigrams

Now we can add the weights of the two cases in decigrams:

56300 decigrams + 45800 decigrams = 102,100 decigrams

Therefore, the two cases weigh 102,100 decigrams together.

30.5

Step-by-step explanation:

the answer is 30.5

The sample indicates that the data does not provide sufficient evidence to support the claim that 20% of plants are infected.

This given test is a test for single sample proportion

The test hypothesis are:

\(H_{o} :p=0.20\), null hypothesis

\(H_{1} :p\neq 0.20\), alternative hypothesis

The test statistic fallows a standard normal distribution and is given by:

\(Z=\frac{x-p}{{\sqrt{p(1-p)/n} } }\)

p=0.20

X=47 plants

Sample size, n=500

x, is the sample mean:

x=X/n=47/500

x=0.094

So, test statistic is calculated as:

\(Z=\frac{0.094-0.20}{\sqrt{0.20(1-0.20)/500} }\)

Z=-5.93

From the z-table, the p-value associated with Z=-5.93 is approximately 0

The decision rule based on p-vale, is to reject the null hypothesis if p-value is less than confidence level

In this case, the p-value is very small and less than confidence level of 0.20, we therefore reject the null hypothesis or the claim

So we conclude that the data does not provide sufficient evidence to support the claim that 20% of plants are infected.

The function represented by the red graph is -

g(x) = 4 - x⁴

A translation is a movement of the graph either horizontally (parallel to the

x - axis) or vertically (parallel to the y -axis).

Given is the graph of the function -

f(x) = 3 - x⁴

In order to shift the graph upwards by one unit upwards, we will make a new function g(x) such that -

g(x) = f(x) + 1

Therefore -

g(x) = 3 - x⁴ + 1

g(x) = 4 - x⁴

Therefore, the function represented by the red graph is -

The 90th percentile of x is 70.

What is standard deviation?

A set of values' variance or dispersion is measured by the standard deviation. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.

Given:  Mean = 80, s = 5.

Computing values to standard deviation from mean,

Lower limit = mean - 2s

                  = 80 - 2(5)

                  = 80 - 10

Lower limit = 70

Hence, if x has a normal distribution with mean 80 and standard deviation 5 then the 90th percentile of x is 70.

c+9/24=32/24 so c=23/24

Answer:

C = 23/24

Step-by-step explanation:

Step 1: Convert 1 1/3 to an improper fraction.

Step 2: Change the denominator of 3/8 and 4/3 to a common denominator: 24.

Step 3: Subtract 9/24 from both sides.

Therefore, C = 23/24.

The function f(x) = x^2 - 9 is a continuous and strictly increasing function for x > 3.

To determine the largest interval on which f has an inverse, we need to find the interval where f(x) is one-to-one (injective).

Since f(x) = x^2 - 9 is strictly increasing, its inverse function will also be strictly increasing. This means that the largest interval on which f has an inverse is the interval where f(x) is strictly increasing, which is x > 3.

Therefore, the largest interval on which f has an inverse is (3, ∞).

To find (f^(-1))'(0), we need to evaluate the derivative of the inverse function at x = 0.

(f^(-1))'(0) = (d/dx)(√(x + 9))|_(x=0)

Using the chain rule, we have:

(f^(-1))'(x) = 1 / (2√(x + 9))

Substituting x = 0:

(f^(-1))'(0) = 1 / (2√(0 + 9))

= 1 / (2√9)

= 1 / (2 * 3)

= 1 / 6

Therefore, (f^(-1))'(0) = 1/6.

The expected value of a ticket in the given lottery game is -$0.60, indicating that, on average, a person can expect to lose $0.60 per ticket.

To calculate the expected value of a ticket, we need to multiply the value of each prize by its respective probability and sum them up.

For the grand prize of $4 million, the probability of winning is 1 divided by the total number of tickets sold, which is 1/3.5 million. Therefore, the contribution to the expected value from the grand prize is (1/3.5 million) * $4 million.

For the second prize of $30, there are 10,000 winners out of 3.5 million tickets sold, giving a probability of 10,000/3.5 million. The contribution from the second prize is (10,000/3.5 million) * $30.

Similarly, for the third prize of $5, there are 50,000 winners out of 3.5 million tickets sold, giving a probability of 50,000/3.5 million. The contribution from the third prize is (50,000/3.5 million) * $5.

To calculate the expected value, we sum up the contributions from each prize and subtract the cost of the ticket, which is $2.

The result is the expected value of -$0.60, indicating an average loss of $0.60 per ticket.

Step-by-step explanation:

The domain of a function g(x) is a subset of the domain of other function f(x).

Function are,

f(x) = -log(x-2)-3

g(x) = -log(x) - 3

The domain of the function f(x) is all real numbers greater than 2 since the argument of the logarithmic function (x-2) must be positive.

The domain of the function g(x) is all real numbers greater than 0 since the argument of the logarithmic function x must be positive.

Comparing the domains of these functions,

The domain of g(x) is a subset of the domain of f(x) .

Since every value in the domain of g(x) all real numbers greater than 0 is also in the domain of f(x) all real numbers greater than 2.

Therefore, the function g(x) has a domain that is contained within the domain of the function f(x).
