How to find if second order polynomials are real and rational
For second order polynomials of the form \(a\cdot x^{2} + b\cdot x + c = 0\), where \(a, b,c \in \mathbb{R}\). roots are real if \(b^{2}-4\cdot a\cdot c \ge 0\). In addition, roots are rational if \(b^{2}-4\cdot a \cdot c = 0\).
If we know that \(a = 3\), \(b = 20\) and \(c < 100\), then the discriminant must be \(400-12\cdot c \ge 0\). We must consider the following case:
Discriminant is 0\(400 - 12\cdot c = 0\)

b²-1 (1-be™™)(be™ −1) 12/17 | X X(e) cos(w)dw 2π X(e): (a) Find x[n] (b) Find |b|<1
The correct answer is any value of b satisfying -1 < b < 1, the condition |b| < 1 is true.
(b) Assuming we are only interested in finding the absolute value of b, we can disregard the expression x[n] and focus on |b| < 1.
To find the absolute value of b, we can consider two cases:
Case 1: b > 0
If b > 0, then |b| = b. In this case, we have 0 < b < 1 to satisfy |b| < 1.
Case 2: b < 0
If b < 0, then |b| = -b. In this case, we have -1 < b < 0 to satisfy |b| < 1.
b) To find |b| < 1, we need to compare the absolute value of b to 1 and check if it is less than 1. Without the specific value of b provided in the expression, we cannot determine whether |b| < 1.

TRUE or FALSE
(a) In a scatterplot, the response is shown on the horizontal axis with the explanatory variable
on the vertical axis.
(b) If all of the data lie along a single line with nonzero slope, then the r
2 of the regression is
1. (Assume the values of the explanatory variable are not identical).
(c) If the correlation between the explanatory variable and the response is zero, then the slope
will also be zero.
(d) The use of a linear equation to describe the assocation between price and sales implies
that we expect equal differences in sales when comparing periods with prices $10 and $11
and periods with prices $20 and $21.
(e) The linear equation (estimated from a sequence of daily observerations):
Estimated shipments = b0 + 0.9*(Orders Processed) implies that we expect twice as many
shipments when the number of orders processed doubles only if b0 = 0.
(f) The intercept estimates how much the response changes on average with changes in the
predictor.
I'll do parts (a) through (c) to get you started
(a) False. The explanatory variable is always along the x axis, and the response variable is along the y axis. The response variable reacts to whatever the input explanatory variable is, hence the name "response".
---------
(b) True. If all data lie along a single straight line with nonzero slope, then either r = -1 or r = 1. If we have all data points on a line with some negative slope, then r = -1. If the regression slope is positive, then r = 1. Either way, it will lead to r^2 = 1 because (1)^2 = 1 and (-1)^2 = 1. In other words, there are two solutions to r^2 = 1 and they are r = -1 or r = 1. In the case of r = -1, we say the data has perfect negative linear correlation. With r = 1, the data has perfect positive linear correlation.
---------
(c) True. If r > 0, then we have some level of positive correlation which means the regression slope is positive in some way. If r < 0, then the regression slope is negative in some way. That must mean r = 0 leads to the regression slope having a flat horizontal line. This could mean one of two things: i) The points are all on or near the same curve such as a parabola, ii) The points are completely randomly scattered about. If case (i) happens, then it's better to use nonlinear regression instead of linear regression.

The number of cases they should order is 14 cases, because it is the maximum number of cases that can accommodate the 7,000 sheets.
What is the number of cases to be ordered?
The number of cases that will accommodate the number of sheets needed is calculated by applying simple proportion method.
Dimension of the package of sheets = 216 mm x 279 mm x 45 mm
The dimension of the package of a case = 216 mm x 279 mm x 270 mm
The only thing that changes here is thickness (270 mm for a case).
if 500 sheets requires = 270 mm thickness case
7000 sheets will require = ?
? = (7000 x 270) / 500
? = 3,780 mm
total of 3,780 thickness cases
1 case = 270 mm
? = 3,780 mm
? = 3,780/270
? = 14 cases

A sociologist is conducting a study on unmarried partners living together in the Pacific Northwest. She finds that 4.5% of all households are made up of unmarried partners from a prior year's census. To further her study, she takes a simple random sample of 400 people. With a 40% chance, the sociologist's sample proportion will be no greater than what value of p? Use Excel to find your answer and round it to the nearest hundredth. Provide your answer below:
σp = ____
p = ____
The standard deviation and proportion value is obtained as 0.02 and 0.05 respectively.
What is standard deviation?
The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.
To find the standard deviation of the sample proportion, we can use the formula -
σp = √(p(1-p)/n)
where p is the population proportion (0.045) and n is the sample size (400).
σp = √(0.045(1-0.045)/400) ≈ 0.0208
To find the value of p that corresponds to a 40% chance of the sample proportion being no greater than that value, we can use the z-score formula -
z = (\(\hat{\rho}\) - p) / σp
where \(\hat{\rho}\) is the sample proportion and p is the population proportion.
For a 40% chance, the corresponding z-score is 0.25 (since 0.40 is halfway between 0.25 and 0.50 on the standard normal distribution).
So we have -
0.25 = (\(\hat{\rho}\) - 0.045) / 0.0208
\(\hat{\rho}\) - 0.045 = 0.0208 × 0.25
\(\hat{\rho}\) ≈ 0.0517
Therefore, the value of p is 0.05, and the value of σp is 0.02.

an environmental protection agency study of 12 automobiles revealed a correlation of 0.47 between engine size and emissions. at the .01 significance level, they want to test whether or not the population correlation is positive. what is the computed value of the test statistic? 0.47 0.22 2.94 1.68
The computed value of the test statistic is 2.94.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We have a sample size of n = 12, engine size (x) and emissions (y) are the two variables being correlated, and the sample correlation coefficient is r = 0.47.
The null hypothesis is that the population correlation is zero (H0: ρ = 0) and the alternative hypothesis is that the population correlation is positive (Ha: ρ > 0).
To compute the test statistic, we need to first calculate the degrees of freedom (df), which is (n-2) = 10 in this case.
We can then use the formula for the test statistic, which is:
t = (r√(df)) / √1 - r²
Substituting the values we have, we get:
t = (0.47 √10) / √(1 - 0.47²)
t = 2.94
Therefore, the computed value of the test statistic is 2.94.

The heart rate increases gradually during the initial stages of exercise and then it increases sharply.
The graph represents a person’s heart rate in beats per minute during 30 minutes of exercise.
The best statement that describes the relationship between heart rate and time during exercise is that the heart rate increases gradually during the initial stages of exercise and then it increases sharply.
Heart rate (HR) is the number of heartbeats per unit of time, generally expressed as beats per minute (BPM), that an individual's heart pumps per minute (bpm).
The pulse is usually determined by evaluating arterial blood flow in any blood vessel that can be palpated near the surface of the skin at various points on the body (peripheral pulse).
Exercise is any physical activity that improves or sustains physical health, overall well-being, and/or athletic ability while also providing entertainment.
Exercise may be done on a regular basis, such as daily, or at a specific time, such as when athletes participate in athletic activities.
Exercise may be performed in a variety of settings, including health clubs, the outdoors, or one's own home.

Select the set that is equivalent to (B∩C)∪∅. ∅ B C B∩C
The set equivalent to (B∩C)∪∅ is B∩C from the intersection of two sets B and C, denoted as B∩C.
In set theory, the intersection of two sets B and C, denoted as B∩C, refers to the set of elements that are common to both B and C. When we take the intersection of two sets, we consider only the elements that appear in both sets and disregard any elements that are unique to either set. The intersection operation results in a new set that contains the common elements.
In this case, we have the intersection of sets B and C, represented as B∩C. The symbol ∪ denotes the union operation, which combines multiple sets to create a new set that contains all the elements from the combined sets, without duplication. However, in this specific scenario, we are taking the union of the intersection (B∩C) with an empty set (∅).
When we take the union of any set with an empty set, the result remains the same as the original set. This is because the empty set has no elements, so adding it to any set does not change the set's contents. Therefore, (B∩C)∪∅ is equivalent to just B∩C.
