Based on the given ratio scale, the distance between these two buildings in feet is 72,000 feet.

Given that the distance between two buildings on campus using a map which has a ratio scale of 1:24,000 as three inches in map units. We have to find the distance between these two buildings in feet.

Conversion formula: 1 inch = 12 feet

Therefore, 3 inches = 3 × 12 = 36 feet.

Now we can find the distance between these two buildings by using the scale factor of the map.The scale factor is the ratio of the real distance to the measured distance. Since we have the ratio scale of the map, we can use it to find the scale factor.

Ratio Scale = 1:24,000

This means that 1 unit on the map is equivalent to 24,000 units in real life. Let x be the distance between the two buildings in real life.

Distance on map / Actual Distance = Ratio Scale

3 inches / x = 1 / 24000

We know that the distance on the map is equal to 3 inches, so we can substitute that value into the equation and solve for x.

3 inches / x = 1 / 24000

Simplifying, we get:

x = 24000 * 3

x = 72,000 feet

Therefore, the distance between these two buildings in feet is 72,000 feet.

The probability that the mean weight of the sample babies would be less than 4068 grams is 0.8666.

We have mean weight as 4022grams,and standard deviation as 266 grams.

We need to check mean weight of the sample will be less than 4068 grams.

It means that on left side mean range is=4022-4068=-46,and

right side mean range =4022+4068=8090

So, we need to find the probability if mean range varies in between from -46 to 8090.

So, we use z-score table to find the z-score for -46 and 8090,we get

We use Z-formula which is given by

Z = (X-μ)/SE

where X is the standard mean.

Using the Z-score table, we get

Z = 0.16917 and -0.161917

Using z-score table, we get that P(0.16917)=0.4333.

Since, both of the probability occupies same space area, due to that total probability =0.4333×2=0.8666

Hence, the probability will be 0.8666.

Given an AR(1) process with drift X = α + βX_{t-1} + ε_t, where α = 2, β = 0.7, and ε_t ~ N(0, 1).To find the mean of the process, we note that the AR(1) process has a mean of μ = α / (1 - β).

So, the mean is 6.67, the variance is 5.41, the first three ACF are 0.68, 0.326, and 0.161, and the first three PACF are 0.7, -0.131, and 0.003.

So, substituting α = 2 and β = 0.7,

we have:μ = α / (1 - β)

= 2 / (1 - 0.7)

= 6.67

To find the variance, we note that the AR(1) process has a variance of σ^2 = (1 / (1 - β^2)).

So, substituting β = 0.7,

we have:σ^2 = (1 / (1 - β^2))

= (1 / (1 - 0.7^2))

= 5.41

To find the first three autocorrelation functions (ACF) and the first 3 partial autocorrelation functions (PACF), we can use the formulas:ρ(k) = β^kρ(1)and

ϕ(k) = β^k for k ≥ 1 and

ρ(0) = 1andϕ(0) = 1

To find the first three ACF, we can substitute k = 1, k = 2, and k = 3 into the formula:

ρ(k) = β^kρ(1) and use the fact that

ρ(1) = β / (1 - β^2).

So, we have:ρ(1) = β / (1 - β^2)

= 0.68ρ(2) = β^2ρ(1)

= (0.7)^2(0.68) = 0.326ρ(3)

= β^3ρ(1) = (0.7)^3(0.68)

= 0.161

To find the first three PACF, we can use the Durbin-Levinson algorithm: ϕ(1) = β = 0.7

ϕ(2) = (ρ(2) - ϕ(1)ρ(1)) / (1 - ϕ(1)^2)

= (0.326 - 0.7(0.68)) / (1 - 0.7^2) = -0.131

ϕ(3) = (ρ(3) - ϕ(1)ρ(2) - ϕ(2)ρ(1)) / (1 - ϕ(1)^2 - ϕ(2)^2)

= (0.161 - 0.7(0.326) - (-0.131)(0.68)) / (1 - 0.7^2 - (-0.131)^2) = 0.003

The number of additions, multiplications, and divisions required to solve an LPP using the two-phase method depends on the specific problem and algorithmic steps, making it difficult to provide a precise count.

We have,

The two-phase method is a technique used to solve linear programming problems (LPP) that involve artificial variables to handle constraints.

It involves two phases:

Phase 1, which finds an initial feasible solution, and Phase 2, which improves the solution to optimize the objective function.

In terms of counting the number of additions, multiplications, and divisions required in the two-phase method, it depends on the specific LPP and the operations performed during the algorithm.

The number of operations can vary depending on the size of the problem (the dimensions of the matrix A and the number of variables) and the specific constraints and objective function.

In general, the two-phase method involves performing matrix operations, such as matrix multiplication, addition, and inversion, as well as solving systems of linear equations and performing arithmetic operations.

The number of operations required will depend on the specific algorithmic steps and the operations involved in each iteration.

Thus,

First, let's list all the possible arrangements of the digits 2, 4, and 6 with a decimal point between two digits: - 2.4.6
- 2.6.4
- 4.2.6
- 4.6.2
- 6.2.4
- 6.4.2

Now, we need to find the sum of every number less than 4.4 than grogg writes. This means we need to add up all the numbers that are less than 4.4 and are also less than each of the six numbers on our list.

Let's start with the first number on our list, 2.4.6. The numbers that are less than 4.4 and less than 2.4.6 are:

- 2.4
- 2.6

So we add those two numbers together:  2.4 + 2.6 = 5, That's the sum for the first number on our list. Now we can repeat this process for each of the other five numbers on our list, and add up all the sums at the end. For 2.6.4, the numbers less than 4.4 and less than 2.6.4 are: - 2.6 .

So the sum for 2.6.4 is:  2.6, For 4.2.6, the numbers less than 4.4 and less than 4.2.6 are:
- 4.2
- 4.6, So the sum for 4.2.6 is: 4.2 + 4.6 = 8.8, For 4.6.2, the numbers less than 4.4 and less than 4.6.2 are:
- 4.2
- 4.6

So the sum for 4.6.2 is:
4.2 + 4.6 = 8.8

For 6.2.4, the numbers less than 4.4 and less than 6.2.4 are:

- None

There are no numbers less than 4.4 and less than 6.2.4, so the sum for 6.2.4 is 0.
Finally, for 6.4.2, the numbers less than 4.4 and less than 6.4.2 are:
- None

Again, there are no numbers less than 4.4 and less than 6.4.2, so the sum for 6.4.2 is 0.
Now we can add up all the sums:  5 + 2.6 + 8.8 + 8.8 + 0 + 0 = 25.2

So the sum of every number less than 4.4 than grogg writes is 25.2.

To compute the median of these fourteen patients' lengths of stay, we need to arrange them in ascending order first: 1, 1, 2, 2, 3, 3, 4, 4, 4, 4, 5, 6, 16. Then, we can find the middle value, which is 4, since there are an even number of values. Therefore, the median length of stay for these fourteen patients is 4.

The median is a measure of central tendency that represents the middle value of a dataset. In this case, we have fourteen patients' lengths of stay, which we need to arrange in ascending order before finding the middle value. Once we have arranged them, we can easily find the median, which is 4. This means that half of the patients stayed for less than 4 days, and half stayed for more than 4 days. The median is a useful measure when the dataset has outliers or extreme values that could affect the mean. In this case, we have one patient who stayed for 16 days, which is much longer than the other patients' lengths of stay. The median is not affected by this extreme value, making it a robust measure of central tendency.

In conclusion, the median length of stay for these fourteen patients is 4. By arranging the lengths of stay in ascending order and finding the middle value, we can determine the central tendency of this dataset. The median is a useful measure when dealing with datasets that have outliers or extreme values, as it is not affected by them. In this case, we have one patient who stayed for much longer than the others, but the median is still a reliable measure of the typical length of stay for these fourteen patients.

Answer:

A

Step-by-step explanation:

a. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores. b. The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.

(a) To find the probability that the sample mean will be within ±5 of the population mean, we can use the Central Limit Theorem (CLT) and the properties of a normal distribution.

The sample mean, is an unbiased estimator of the population mean, μ. According to the CLT, the distribution of sample means approaches a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

     = 200 / √400

     = 200 / 20

     = 10

To find the probability that the sample mean will be within ±5 of the population mean, we can standardize the interval using the z-score:

For the lower bound (-5), the z-score is (-5 - 0) / 10 = -0.5.

For the upper bound (+5), the z-score is (5 - 0) / 10 = 0.5.

We can now use a standard normal distribution table or technology (such as a calculator or statistical software) to find the probability associated with the z-scores -0.5 and 0.5. The probability that the sample mean will be within ±5 of the population mean is the area under the normal curve between these two z-scores.

(b) To find the probability that the sample mean will be within ±10 of the population mean, we follow the same steps as in part (a).

The lower bound z-score is (-10 - 0) / 10 = -1, and the upper bound z-score is (10 - 0) / 10 = 1. We can use the same normal distribution table or technology to find the probability associated with these z-scores.
