The value of m =  87 kg

The magnitude of force = 978.87 N

use Newton's second law (F = ma) to determine the mass of the man.

Then Tension force

= 192 kg.wt * 9.81 N/kg

≈ 1883.52 N

Net force = (Mass of lift + Mass of man) * Acceleration

Net force = (98 kg + m) * 1.4 m/s²

Net force = Tension force - Gravitational force

(98 kg + m) * 1.4 m/s²

= 1883.52 N - (98 kg + m) * 9.81 m/s²

Now, we can solve for m:

137.2 kg + 1.4m = 1883.52 N - 960.18 kg - 9.81m

10.61m = 923.34

m ≈ 87 kg

The mass of the man is approximately 87 kg

Force exerted by man = (87 kg * 9.81 m/s²) + (87 kg * 1.4 m/s²)

≈ 857.07 N + 121.8 N

≈ 978.87 N

a. Decision rule: Reject the null hypothesis if the calculated z-value is less than or equal to -1.28. b. Calculated z-value: -1.8892. c. Conclusion: Reject the null hypothesis, indicating evidence that the population mean is less than 128.

To complete parts (a) through (c), we need to perform a hypothesis test for the given hypotheses

H0: μ = 128 (null hypothesis)

HA: μ ≤ 128 (alternative hypothesis)

Given: X= 119 (sample mean)

σ = 27 (population standard deviation)

n = 46 (sample size)

α = 0.10 (significance level)

a. The decision rule is to reject the null hypothesis if the calculated value of the test statistic is less than or equal to the critical value(s) of the test statistic. Since the alternative hypothesis is one-sided (μ ≤ 128), we will use a one-sample z-test and compare the calculated z-value with the critical z-value.

To find the critical z-value, we need to determine the z-value corresponding to the significance level α = 0.10. Looking up the critical value in the standard normal distribution table, we find that the critical z-value is -1.28 (rounded to two decimal places).

b. The calculated value of the test statistic, in this case, is the z-value. We can calculate the z-value using the formula

z = (X - μ) / (σ / √n)

Substituting the given values:

z = (119 - 128) / (27 / √46) ≈ -1.8892 (rounded to two decimal places)

c. The conclusion is based on comparing the calculated value of the test statistic with the critical value. Since the calculated z-value of -1.8892 is less than the critical z-value of -1.28, we have enough evidence to reject the null hypothesis. Therefore, we conclude that the population mean is less than 128.

The conclusion statement in part (c) is inconsistent with the given alternative hypothesis and should be revised accordingly.

The sample size used in the analysis was 300 sales calls for the given standard error.

The standard error (SE) is a statistical sample population's approximate standard deviation. The difference between the population's computed mean and one that is widely regarded as correct is described by the standard error. The standard error tends to be reduced the more data points included in the mean computations.

Given that, Lori obtains a book adoption on 20%, and the proportion of 0.400.

The Standard error is given as:

SE = √[p(1-p)/n]

Rearranging for n we have:

n = p(1-p)/(SE²)

n = 0.20(1-0.20)/(0.0400)²

n = 300.25

Let p be the proportion of residents in the town who are unemployed. The null hypothesis \($H_0$\) is that the proportion of unemployed residents in the town is the same as the national unemployment rate of 8%. The alternative hypothesis \($H_a$\) is that the proportion of unemployed residents in the town is significantly lower than the national unemployment rate.

Using the appropriate notation, the hypotheses can be expressed as:

$H_0: p = 0.08$

Answer:

THe number of freezers that can be shipped along with 50 ovens is 40

Step-by-step explanation:

total weight of ovens being shipped is 18000 lb. and in order to find the excess weight we have to subtract the ovens weight and the total carrier weight.

equation is:

42,000 - 18000= 24000 lbs.

you then divide the left over pounds by the weight of the freezers to get the total amount of freezers that can be put into a railcar.

24000/600=40

So 40 freezers and 90 ovens can fit within one railcar.

Raoult's law equation, p1 = χ1 x p°1, relates the vapor pressure of a component in a solution to its mole fraction and the vapor pressure of the pure component.

In the equation p1 = χ1 x p°1, each term has a specific meaning:

p1 represents the vapor pressure of the component in the solution. Vapor pressure is the pressure exerted by the vapor phase when a substance is in equilibrium with its liquid phase at a given temperature.

χ1 is the mole fraction of the component in the solution. Mole fraction is a way to express the relative amount of a component in a mixture, defined as the ratio of the moles of the component to the total moles in the mixture.

p°1 refers to the vapor pressure of the pure component. It is the vapor pressure of the component when it is in its pure, undiluted state at the same temperature as the solution.

Raoult's law states that for an ideal solution, the vapor pressure of a component in a solution is directly proportional to its mole fraction in the solution and the vapor pressure of the pure component.

In other words, the partial pressure of a component in the vapor phase is equal to the mole fraction of that component multiplied by its vapor pressure in the pure state. This relationship assumes ideal behavior and is applicable for solutions where the intermolecular interactions between the components are similar.

Researchers try to gain insight into the characteristics of a sample population by examining a sample of the population.

A sample is a subset of individuals or units taken from a larger population. Researchers use sampling methods to select a representative group of individuals from the population they are interested in studying. By studying the sample, researchers can make inferences and draw conclusions about the characteristics, behaviors, or trends that may exist within the entire population.

The goal of sampling is to obtain a sample that accurately represents the population in terms of its relevant characteristics. Researchers carefully select their samples to ensure that they are representative and minimize bias. This allows them to generalize the findings from the sample to the larger population with a certain level of confidence.

By examining a sample, researchers can collect data, analyze patterns, and draw conclusions about the population as a whole. This approach is more feasible and practical than attempting to study the entire population, especially when the population is large or geographically dispersed.

The proportion of carrying loads in the sample that are less than or equal to 880 pounds per square foot is 0.12.

To find the proportion of carrying loads in the sample that are less than NM pounds per square foot, we need to sum up the frequencies of all the bins that have carrying loads less than NM.

Given the histogram data:

Carrying Load (in pounds per sq. ft) | Frequency

860-880 3

880-900 6

900-920 9

920-940 4

940-960 3

Let's assume NM is the upper limit of the desired range for the carrying load. To calculate the proportion of carrying loads less than NM, we need to add up the frequencies of all the bins with carrying loads below NM.

For example, if NM is less than or equal to 880, then all the frequencies of the first bin (860-880) will be included in the calculation. If NM is between 880 and 900, the frequencies of both the first and second bins will be included, and so on.

To find the proportion, we sum up the frequencies of the relevant bins and divide it by the total sample size.

For the given histogram data, the total sample size is:

Total sample size = 3 + 6 + 9 + 4 + 3 = 25

Let's calculate the proportion for NM values less than or equal to 880:

Proportion = (Frequency of bin 1) / (Total sample size) = 3 / 25 = 0.12

Therefore, the proportion of carrying loads in the sample that are less than or equal to 880 pounds per square foot is 0.12.

Note: The exact value of NM was not provided, so we calculated the proportion for NM values less than or equal to 880 as an example. The calculation can be done for any specific NM value by summing up the frequencies of the relevant bins and dividing by the total sample size.

Now, According to the question:

"Information available from the question"

s/a = 4; l/a = 0.20; i/e = 0.10; a = l e and a = 100.

We have to find the i/s

We can first find the value of e, using the equation a = l + e, where l/a = 0.20 and a = 100:

e = a - (l/a) * a = 100 - (0.20 * 100) = 100 - 20 = 80

Next, we can find the value of i using the given information i/e = 0.10:

i = i/e * e = 0.10 * 80 = 8

Finally, we can find the value of i/S using the equation i/S = i / (S/a) * a = 8 / (4 * 100) = 8 / 400 = 0.02.

The mean absolute deviation for the given dataset of 3, 6, 3.8, 3.2, and 3.4 is approximately 0.996. This means that, on average, each data point in the dataset deviates from the mean by approximately 0.996.

The mean absolute deviation (MAD) measures the average distance between each data point and the mean of the dataset. To find the MAD, you need to follow these steps:

1. Calculate the mean of the dataset by adding up all the numbers and dividing the sum by the total number of data points. In this case, the dataset consists of the following numbers: 3, 6, 3.8, 3.2, and 3.4. Adding them up gives us a sum of 19.4. Dividing this sum by 5 (since there are 5 data points) gives us a mean of 3.88.

2. Find the absolute deviation for each data point by subtracting the mean from each data point and taking the absolute value. For example, for the first data point, 3, the absolute deviation would be |3 - 3.88| = 0.88. Repeat this step for all the data points.

3. Calculate the mean of the absolute deviations by adding up all the absolute deviations and dividing the sum by the total number of data points. In this case, the absolute deviations are: 0.88, 2.12, 0.72, 0.68, and 0.58. Adding them up gives us a sum of 4.98. Dividing this sum by 5 gives us a mean of 0.996.

So, the mean absolute deviation for the given dataset is approximately 0.996.


The mean absolute deviation helps us understand how much each data point varies from the mean of the dataset. By calculating the absolute deviation for each data point and finding the average, we can determine the typical amount of variation in the dataset.


The mean absolute deviation for the given dataset of 3, 6, 3.8, 3.2, and 3.4 is approximately 0.996. This means that, on average, each data point in the dataset deviates from the mean by approximately 0.996.

The correct answer is the average speed for the entire trip is 34.5 miles per hour and The integral that represents this information is as follows: f(x)dx = ∫23 dx + ∫69 dx Where x represents the distance travelled in miles.

To find out the average speed for the entire trip, we will use the formula for average speed which is given as follows: Average speed = Total distance/Total time

Let's calculate the time taken to travel 138 miles at 23 mi/h

Speed = 23 mi/h

Distance = 138 mi

Time taken = Distance/Speed = 138/23 = 6 hours

Now, let's calculate the time taken to return back to the starting point, which is again 138 miles away but this time at 69 mi/h.

Speed = 69 mi/h

Distance = 138 mi

Time taken = Distance/Speed = 138/69 = 2 hours

Now, the total time taken for the entire trip is 6 + 2 = 8 hours.

The total distance travelled for the entire trip is 2 x 138 = 276 miles.

Now we can use the formula for average speed to calculate the average speed of the entire trip.

Average speed = Total distance/Total time = 276/8 = 34.5 miles per hour

Therefore, the average speed for the entire trip is 34.5 miles per hour.

The integral that represents this information is as follows: f(x)dx = ∫23 dx + ∫69 dx Where x represents the distance travelled in miles.

The limits of integration are from 0 to 138 for both integrals, representing the forward and backward journeys.

The equation of the absolute value function with the given vertex at (1, 3), passing from (-1, 5) and (3, 5) is f(x) = |x - 1| + 3.

Hence, the correct option 3rd.

Given is a graph of an absolute value function, having a vertex at (1, 3), passing from (-1, 5) and (3, 5).

We need to find the equation of the function.

To find the equation of the absolute value function, we need to consider its general form:

f(x) = a |x - h| + k

where (h, k) represents the vertex of the absolute value function.

In this case, the vertex is given as (1, 3), so h = 1 and k = 3.

Additionally, we are given two other points on the graph: descending at (-1, 5) and ascending at (3, 5).

Since absolute value functions are symmetrical around their vertex, the distances from the vertex to these two points are the same.

Therefore, the "a" value will be the slope of the line connecting the vertex to either of the given points.

Step 1: Find the slope "a."

The slope is given by (change in y) / (change in x). We can choose either of the given points to calculate the slope:

Slope =

\(\frac {(5 - 3)}{(3 - 1)}\\\\ = \frac{2}{2}\\\\ = 1\)

Step 2: Write the equation using the vertex and slope:

Now, we have the values of a, h, and k:

a = 1

h = 1

k = 3

The equation of the absolute value function is:

f(x) = 1 × |x - 1| + 3

Simplifying further:

f(x) = |x - 1| + 3

This is the required equation.

Hence the correct option 3rd.

where P is the monthly payment, r is the monthly interest rate (which is the nominal annual rate divided by 12), PV is the present value of the loan (which is $50,000), and n is the total number of monthly payments (which is 6 years times 12 months per year, or 72).

First, we need to calculate the monthly interest rate:

r = 0.10/12 = 0.0083333
