16.2 is 13% of what? Rounded to the nearest tenth place
Answers
Answer:
124.6
Explanation:
Let the number be x.
Thus, we have that: 13% of x =16.2
\(\frac{13}{100}x=16.2\)Next, solve for x by cross-multiplying.
\(\begin{gathered} 13x=16.2\times100 \\ 13x=1620 \end{gathered}\)Divide both sides by 13.
\(\begin{gathered} \frac{13x}{13}=\frac{1620}{13} \\ x=124\frac{8}{13} \\ x\approx124.6\text{ (to the nearest tenth)} \end{gathered}\)Thus, 16.2 is 13% of 124.6 (rounded to the nearest tenth).

d. When the population standard deviation is much greater than 5
Answers
The circumstance that the score is located 5 points above the mean a central value, relatively close to the mean is when the population standard deviation is much greater than 5.
What is the standard deviation?Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.
Here, we have
The circumstance is a score that is 5 points above the mean considered a central value.We have to find under what circumstances is a score that is 5 points above the mean considered a central value--meaning it is relatively close to the mean.
We concluded from the above statement that when the population standard deviation is much greater than 5.
Hence, when the population standard deviation is much greater than 5 then, the score that is 5 points above the mean is considered a central value.
Therefore, the correct option is D.

Answer:
\(36\)
Step-by-step explanation:
The expression \(_nC_k\) is used to denote the number of ways you can choose \(k\) things from a set of \(n\) things. It is equal to:
\(_nC_k=\binom{n}{k}=\frac{n!}{k!(n-k)!}\)
In this case, \(n=9\) and \(k=2\), so:
\(\implies \frac{9!}{2!(9-2)!}=\frac{9!}{2!7!}=\boxed{36}\)
You can also think of it like this:
\(_9C_2\) is saying 9 choose 2. We are choosing 2 things from a set of 9 things, where order doesn't matter. For the first thing we choose, there are 9 options. Then 8 options, 7, and so on. Since we're only choosing two things, there are \(9\cdot 8=72\) permutations. However, the order of which we choose each thing does not affect what we've chosen overall (e.g. If we're choosing two donut flavors original and strawberry, it doesn't matter which flavor I choose first, because I'm still getting the same two flavors). Therefore, we must divide this by the number of ways we can arrange two distinct values, which is \(2!\). Our answer is thus \(\frac{72}{2!}=\frac{72}{2}=\boxed{36}\)
=========================================================
Explanation:
We have 9*8 = 72 different permutations. This is if we used the nPr formula with n = 9 and r = 2.
Notice the countdown from 9 to 8. This is because we don't reuse the same element twice.
Since order doesn't matter with nCr, we will divide by 2. This is because something like AB is the same as BA. So we go from 72 to 72/2 = 36
The value 36 is found in Pascal's Triangle in the row that has 1,9,... at the start of it. Start at the left hand side and count exactly 3 spaces to the right, and you should land on 36.

Yes, the figure shown in the xy-coordinate plane is a parallelogram because side OP is parallel to side TS and side OT is parallel to side PS
How to determine whether the quadrilateral is a parallelogram by using slope?In order for any quadrilateral to be considered a parallelogram, two pairs of its parallel sides must be equal (congruent). Therefore, we would determine the slope of each side by using this mathematical equation:
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
For side OP, the slope is given by:
Slope (m) = (b - 0)/(a - 0)
Slope (m) = b/a.
For side TS, the slope is given by:
Slope (m) = (0 - )/(c - (a + c))
Slope (m) = -b/-a = b/a
Therefore, side OP is parallel to side TS.
For side OT, the slope is given by:
Slope (m) = (0 - 0)/(c - 0)
Slope (m) = 0.
For side PS, the slope is given by:
Slope (m) = (b - b)/((a + c) - c)
Slope (m) = 0
In conclusion, the figure shown above is a parallelogram because side OT is parallel to side PS and side OP is parallel to side TS.

if we define our population as all the households in the city of chicago, and we use the chicago telephone directory from which to draw our sample units, we would likely have: a. a survey with sample frame error. b. a representative survey. c. a survey containing error. d. a census.
Answers
If we define our population as all the households in the city of Chicago and use the Chicago telephone directory to draw our sample units, we would likely have a survey with sample frame error. Correct option is A.
Sample frame error occurs when the sampling frame, in this case, the Chicago telephone directory, does not accurately represent the population of interest.
In this case, the telephone directory would exclude households without a landline phone or those who choose not to have their phone number listed. This means that the sample would not include all households in the population, leading to biased results.
A representative survey (option B) would be one in which the sample accurately represents the population in terms of relevant characteristics such as age, gender, income, education, and other important demographic factors.
In contrast, a survey containing error (option C) is a general term that includes both sampling error and non-sampling error, such as measurement error or response bias.
Finally, a census (option D) is a study in which data is collected from all individuals or units in a population, not just a sample. Therefore, using a telephone directory to draw a sample from the population does not constitute a census.
In conclusion, using the Chicago telephone directory to draw a sample of households would likely result in a survey with sample frame error, which can lead to biased results and limit the generalizability of the findings to the entire population.

2. C. point C.

Step-by-step explanation:
1. In order to find the graph's y-intercept, we need to locate the point where the line crosses the y-axis. This will always happen at x=0, therefore, the y-intercept is located at point B (0,-4)
2. In order to find the x-intercept, we need to find the point where the line crosses the x-axis. This will generally happen when y=0, so that will be point C (2,0)
3. In order to find the graph's zero, we need to find the point where y=0. In other words, the graph's zero is the point where the function is equal to zero (the x-intercept) so this will br point C again (2,0)
The polynomial (x – 2)(x^2 + 1) – x(x – 3) can be written in the form: ax^3 + bx^2 + cx + d where a, b, c, and d are constants. What are the values of a, b, c, and d? Show your work.
Answers
Therefore the polynomial (x – 2)(x^2 + 1) – x(x – 3) can be written in the form: ax^3 + bx^2 + cx + d = x^3 - 2x^2 + 4x - 6 where a = 1, b = -2, c = 4, and d = -2
What is the polynomial after simplificationThe polynomial (x – 2)(x^2 + 1) – x(x – 3) can be written as:
ax^3 + bx^2 + cx + d = (x - 2)(x^2 + 1) - x(x - 3)
To find the values of a, b, c, and d, we need to multiply out the binomials and combine like terms. Using the distributive property, we get:
ax^3 + bx^2 + cx + d = x^3 - 2x^2 + x^2 + x - x^2 + 3x - 2
Now we can combine like terms:
ax^3 + bx^2 + cx + d = x^3 - 2x^2 + 4x - 2
So we can see that:
a = 1, b = -2, c = 4, and d = -2

D.2 How many times larger is the amount of blood your heart has pumped in the last day than the amount of food and drink you took in? D.3 How much error do you expect in your answer to 4 b ? You should give an quantitative response to this, but not one generated by a formula. Instead, estimate the error by examining how closely you think you know the values you estimated for food intake and blood flow. You don't need to use advanced error propagation; an approximate response is fine. D.4 What is the relevance of this calculation to the theory that all the blood that flows through your veins is generated in the liver?
Answers
An estimate for the total volume of food and water you've ingested in the last day is 3000-5000 milliliters. On average, the heart pumps about 5 liters of blood per minute. 10-20% or more error I'm expecting. Calculating heart blood volume compared to food and drink consumption is crucial for understanding circulation and liver function.
D.1 Estimating the amount of food and water consumed in a day can be difficult without specific measurements, but a rough estimate can be made based on typical intake amounts. On average, a person may consume 2-3 liters of water and 1000-2000 calories per day, resulting in an estimated total volume of 3000-5000 milliliters.
D.2 The amount of blood pumped by the heart varies from person to person and depends on factors such as heart rate and overall health. On average, the heart pumps about 5 liters of blood per minute, which is much larger than the estimated volume of food and water intake.
D.3 Estimating food and water intake and blood flow is prone to error due to variability and uncertainties in personal measurements. Individuals' habits, health, and physical activity levels can affect these estimates, potentially resulting in a significant error of 10-20% or more.
D.4 The calculation of the heart's blood volume compared to food and drink consumption is crucial for understanding the circulation system and liver role.
The liver processes nutrients, detoxifies, and produces blood components, while the heart is responsible for circulating blood throughout the body. The vast difference in volume between the two is emphasized, emphasizing the heart's crucial role in maintaining circulation.
