Option B) 1,390,072 is correct. The population of the city after 12 years can be calculated using the formula for compound interest.

To calculate the population of a city after 12 years using the formula for compound interest, we first need to identify the initial population (P0), the annual interest rate (r), and the number of years (n). We can then plug these values into the formula P = P0(1 + r/100)ⁿ. In this case, the initial population is given as 909327, the annual interest rate is 3.6%, and the number of years is 12. By substituting these values into the formula, we get P = 909327 * (1 + 3.6/100)¹² ≈ 1390072, which represents the population of the city after 12 years. Therefore, option B) 1,390,072 is the correct answer.

Step-by-step explanation:

The estimated percentage of idle time for air-express cargo loaders is approximately 9.09%.

To calculate the estimated percentage of idle time, we need to divide the number of observations in which the loaders were idle by the total number of observations and multiply by 100.

In this case, the loaders were idle in 5 out of 55 observations. Dividing 5 by 55 gives us 0.0909. Multiplying this by 100, we find that the estimated percentage of idle time is approximately 9.09%.

This means that, based on the initial survey, it is estimated that the loaders are idle approximately 9.09% of the time. This information provides an insight into the frequency or occurrence of idle periods for the air-express cargo loaders and can be used to evaluate their efficiency or productivity.

The probability of choosing sausage and onion by Rosa's mom from the given 8 different toppings as per given condition is equal to

(1/ ⁸C₂).

As given in the question,

Total number of different toppings = 8

Number of different toppings choose by Rosa's mom randomly = 2

Possibility of choosing sausage and onion (any one) = 1

Total number of outcomes = ⁸C₂

Number of favorable outcomes = 1

Probability of choosing sausage and onion ( exactly ) one topping

= ( Number of favorable outcomes ) / ( Total number of outcomes )

= ( 1/⁸C₂ )

Therefore, the probability when Rosa's mom chooses sausage and onion out of 8 toppings is equal to ( 1/⁸C₂ ).

To prove that 3 divides n^3 + 2n for any positive integer n, we need to show that there exists an integer k such that n^3 + 2n = 3k.

Let's proceed with the proof using mathematical induction:

Base case:

For n = 1, we have 1^3 + 2(1) = 1 + 2 = 3, which is divisible by 3. So the statement holds true for n = 1.

Inductive hypothesis:

Assume that the statement holds true for some positive integer k, i.e., k^3 + 2k = 3m, where m is an integer.

Inductive step:

We need to prove that the statement holds true for k + 1, i.e., (k + 1)^3 + 2(k + 1) = 3p, where p is an integer.

Expanding the expression (k + 1)^3 + 2(k + 1):

= k^3 + 3k^2 + 3k + 1 + 2k + 2

= (k^3 + 2k) + 3k^2 + 3k + 3

= 3m + 3k^2 + 3k + 3

= 3(m + k^2 + k + 1)

From the inductive hypothesis, we know that k^3 + 2k = 3m. Substituting this in the above expression:

= 3m + 3k^2 + 3k + 3

= 3(m + k^2 + k + 1)

We can see that the expression is a multiple of 3, with (m + k^2 + k + 1) as the coefficient.

Since m, k, and 1 are integers, (m + k^2 + k + 1) is also an integer. Therefore, (k + 1)^3 + 2(k + 1) is divisible by 3.

By using mathematical induction, we have proved that for any positive integer n, 3 divides n^3 + 2n.

The domain would only include positive numbers.

Explanation:

The domain of a function represents the set of all possible input values for which the function is defined. In this case, the function represents the miles per gallon your car gets, which is a ratio of distance (miles) to fuel consumption (gallons).

Since distance and fuel consumption can both be expressed as positive real numbers, the domain of the function should include only positive real numbers. Integers and positive integers are too restrictive for the domain since it is possible to get non-integer values for miles per gallon, such as 24.5 miles per gallon. Therefore, the correct answer is that the domain would only include positive numbers.

The method you are referring to is called "stepwise regression." Stepwise regression is a useful technique in identifying the most important predictors of a response variable.

Stepwise regression is a statistical technique used in linear regression analysis to identify the set of predictor variables that best explain the variability in the response variable. The technique involves sequentially removing variables that have the least impact on the model's explanatory power until a set of useful predictor variables is identified.

Stepwise regression can be performed in either a forward or backward manner. In forward stepwise regression, variables are added to the model one at a time until no more significant variables can be added. In backward stepwise regression, all variables are included in the model initially, and then variables are removed one at a time until no more significant variables can be removed. A variation of stepwise regression is the bidirectional stepwise regression, which involves both forward and backward elimination of variables. The selection of variables is usually based on their statistical significance in predicting the response variable. This can be determined by comparing the p-values of each variable's coefficient estimate against a chosen significance level (e.g., 0.05). Variables with p-values below the significance level are considered significant and are retained in the model, while variables with p-values above the significance level are removed.

The linear model that represents the cost of any number of candy bars can be written as: C = $1.90B + $0.95

To write the linear model that models the cost of any number of candy bars, we need to find the equation of a line that best fits the given data points. We'll use the variables B for the number of candy bars purchased and C for the total cost of the candy bars.

Looking at the given data, we can see that there is a linear relationship between the number of candy bars and the total cost. As the number of candy bars increases, the total cost also increases.

To find the equation of the line, we need to determine the slope and the y-intercept. We can use the formula for the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope (m) using two points from the given data, for example, (3, $6.65) and (25, $48.45):

m = (C2 - C1) / (B2 - B1)

 = ($48.45 - $6.65) / (25 - 3)

 = $41.80 / 22

 ≈ $1.90

Now, let's find the y-intercept (b) using one of the data points, for example, (3, $6.65):

b = C - mB

 = $6.65 - ($1.90 * 3)

 = $6.65 - $5.70

 ≈ $0.95

Therefore, the linear model that represents the cost of any number of candy bars can be written as:

C = $1.90B + $0.95

This equation represents a linear relationship between the number of candy bars (B) and the total cost (C). For any given value of B, you can substitute it into the equation to find the corresponding estimated total cost of the candy bars.

Answer:

17.9 degrees

Step-by-step explanation:

Relative to the unknown angle, angle P, we have 3.2 is the opposite side and 9.9 is the adjacent side.

We have o for opposite and a for adjacent.

Thus we should use TOA, as the o and the a can both be found in TOA.

TOA tells us to use tangent (T for tangent)

So we have tangent x= opposite/adjacent

So we have tangent x= 3.2/9.9

tangent^-1 (3.2/9.9)=x

x=17.9 degrees

The Variance is the anticipated squared deviation of a scattered variable from its population or sample mean. The difference is 36.

Since the standard deviation is defined as the square root of the friction, the friction is the forecourt of the standard deviation.

Since the variance is a square unit, this would produce strange results if you were measuring altitude in measures, for illustration.

Given

standard divagation = 6

Var = SD²

Var = 6² = 36

The deviation would also be in square measures( and it is). We thus take the square root of the friction to be attained, which thus has the same units as the mean.

The friction is the mean of the squared diversions from the mean, while the standard divagation is the square root of that number. Both measures reflect the variability of the distribution, but their units are different the standard divagation is expressed in the same units as the original values(e.g. minutes or measures).

Probability Distributions for Discrete Random Variables are

a. P(X = 3) = 0.2

b. P(X < 3) = 0.3

c. P(2 < X < 5) = 0.5

To solve the given problems, we need to determine the missing probability value for X = 3. Let's calculate it and then proceed with the rest of the questions.

Given:

X 1 2 3 4 5

P(x) 0.1 0.2 ? 0.3 0.2

To find the missing probability value:

0.1 + 0.2 + P(X = 3) + 0.3 + 0.2 = 1

0.8 + P(X = 3) = 1

P(X = 3) = 1 - 0.8

P(X = 3) = 0.2

Now, we can answer the questions:

a. P(X = 3) = 0.2

b. P(X < 3) = P(X = 1) + P(X = 2)

= 0.1 + 0.2

= 0.3

c. P(2 < X < 5) = P(X = 3) + P(X = 4)

= 0.2 + 0.3

= 0.5

Therefore,  Probability Distributions for Discrete Random Variables are

a. P(X = 3) = 0.2

b. P(X < 3) = 0.3

c. P(2 < X < 5) = 0.5
