Does an X or y-axis scale have to always start at zero?.
Answers
No, X or y-axis scale does not have to always start at zero. In a line chart, it's OK to start the axis at a number other than zero
Define axis.A line that is used to take or mark measurements is known as an axis in mathematics. Two crucial axes of the coordinate plane are the x and y axes. A horizontal number line is the x-axis, while a vertical number line is the y-axis. The coordinate plane is created by the perpendicular intersection of these two axes.

Answers
Let f be a function such that lim h->0 ( f(2+h)-f(2) / h ) = 5. Which of the following are true?
I) f is continuous at x=2
II) f is differentiable at x=2
III) The derivative of f is coninuous at x=2
Answers
I) f is continuous at x=2
II) f is differentiable at x=2
These both f (function ) are true
The given limit can be recognized as the definition of the derivative of f at x=2. Specifically, it states that the derivative of f at x=2 is equal to 5.
Using this information, we can make the following conclusions:
I) We cannot say for sure whether f is continuous at x=2 based on the given limit alone. While a function being differentiable at a point implies that it is also continuous at that point, the converse is not necessarily true. Therefore, we would need additional information to determine whether f is continuous at x=2.
II) The given limit implies that f is differentiable at x=2, since the limit exists and is finite. Specifically, we can say that the derivative of f at x=2 exists and is equal to 5.
III) The given limit also implies that the derivative of f is continuous at x=2. This is because the limit defines a continuous function at x=2, and it is well-known that if a function is differentiable at a point, then it is also continuous at that point.
Therefore, the correct answers are II and III.

Linear Classifier of the Generative Multinomial Model
1 point possible (graded)
Consider the prediction classifier for the two classes + and introduced in the above video. For this problem, let 0 and 1 represent the classes + and -, respectively.
Let W = {Thor, Loki, Hulk}. Let p (Thor 0) = p (Loki(0) = p (Hulk|0) = 1/3 and let p (Thor 1) = p(Loki 1) = 1/4 and p (Hulk 1) = 1/2.
We see the following document D= Thor Thor Hulk Loki Loki. To what class would you classify the document to using the linear classifier for the generative multinomial model? (Type "O" for class 0 (+) and "1" for class 1 (-)).
Answers
We classify the document to class 1, which represents the "-" class. Therefore, the answer is 1.
Linear Classifier of the Generative Multinomial Model Let us first calculate the values of ω_jk and ω_0k.
For this purpose, we use the following formulas:ω_jk = log(P(tkj)/P(tkj)),
where tjk is the number of times the word k occurs in the class j documents.ω_0k = log(P(k/1)/P(k/0)),
where k is the number of times the word k occurs in all documents.
In this case, we have three words, so we need to calculate three values of ω_jk for each of the two classes, and three values of ω_0k.ω_0Thor
= log(1/5)/log(2/10)
= -0.301ω_1Thor
= log(1/4)/log(4/10)
= 0.223ω_0Loki = log(0/5)/log(2/10)
= -infω_1Loki = log(2/4)/log(4/10) = 0.182ω_0Hulk
= log(1/5)/log(2/10) = -0.301ω_1Hulk
= log(2/4)/log(4/10) = 0.182
Next, we calculate the score for each class: score(0) = ω_00 + ω_0Thor*2 + ω_0Hulk*1 + ω_0Loki*2
= -0.301 + (-0.301)*2 + (-0.301)*1 + (-inf)*2
= -inf score(1) = ω_10 + ω_1Thor*2 + ω_1Hulk*1 + ω_1Loki*2 = 0.0 + (0.223)*2 + (0.182)*1 + (0.182)*2
= 0.992Since score(1) > score(0),

Determine whether the origin is included in the shaded region and whether the shaded region is above or below the line for the graph of the following: y < 1/3x + 4
Answers
Answer:
The origin is included in the shaded region and the shaded region is below the line.
Explanation:
First, let's graph the line that separates the region: y = 1/3 x + 4
So, to graph the line, we need to find two points in the line as follows:
If x = 0, then y is equal to:
y = 1/3 (0) + 4
y = 4
If x = 3, then y is equal to:
y = 1/3 (3) + 4
y = 1 + 4
y = 5
So, using the points (0, 4) and (3, 5), we get:
Now, we can determine whether the origin is included or not replacing x and y by the coordinates of the origin (0, 0) and determine if this point satisfies the inequality. So:
y < 1/3x + 4
0 < 1/3(0) + 4
0 < 0 + 4
0 < 4
Since 0 is less than 4, the origin is included in the shaded region, so the shaded region is below the line.

according to chebyshev's theorem, at least what percent of any set of observations will be within 1.8 standard deviations of the mean? (round your answer to the nearest whole percent.)
Answers
According to Chebyshev's theorem, at least 69 percent of any set of observations will be within 1.8 standard deviations of the mean.
Standard deviations of the mean = 1.8 s
According to Chebyshev's theorem at least (1 - 1/k^2)×100% observations will lie within k standard deviation from the mean.
The proportion of observations that will be within 1.8 standard deviations of the mean = (1 - 1/(1.8)^2)×100%
The proportion of observations that will be within 1.8 standard deviations of the mean = (1 - 1/3.24)×100%
The proportion of observations that will be within 1.8 standard deviations of the mean = (1 - 0.31)×100%
The proportion of observations that will be within 1.8 standard deviations of the mean = 0.69 × 100%
The proportion of observations that will be within 1.8 standard deviations of the mean = 69%

A random sample of 100 men is chosen from a population * Uh mean height 70 inch and standard deviation 2.5 inch. What is the probability that the average height of the sample men is greater than 69.5
Answers
The probability that the average height of the sample men is greater than 69.5 inches is approximately 0.9772 or 97.72%.
To find the probability that the average height of the sample men is greater than 69.5 inches, we will use the Central Limit Theorem and the z-score formula.
Identify the given values:
- Population mean (μ) = 70 inches
- Population standard deviation (σ) = 2.5 inches
- Sample size (n) = 100
- Sample mean (\(\bar{x}\)) = 69.5 inches.
According to the Central Limit Theorem, the distribution of sample means will be approximately normally distributed with mean μ and standard deviation σ/√n.
Calculate the standard deviation of the sample means \((\sigma \bar{x} )\)
\((\sigma \bar{x} ) = \sigma /\sqrt{n }\)
= 2.5/√100
= 2.5/10
= 0.25
Calculate the z-score using the formula:
\(z = ([\bar{x}- \mu )/\sigma\bar{x}\)
= (69.5 - 70)/0.25 = -0.5/0.25
= -2
Use a z-table or calculator to find the probability that a z-score is greater than -2:
P(z > -2) = 1 - P(z ≤ -2) = 1 - 0.0228 = 0.9772.

Which of the following parametric curves trace out the unit circle (possibly more than once)? (a) (cost, sin t) (b) (sin2t, cos t) (c) (sin(), cos()) (d) (sin 2t, cos 2t) 0sts 2元
Answers
The parametric curves that trace out the unit circle are (a) (cost, sin t) and (c) (sin t, cos t).
(a) In the parametric curve (cost, sin t), the x-coordinate is given by cost and the y-coordinate is given by sin t. By using the trigonometric identity cos^2 t + sin^2 t = 1, we can see that the x-coordinate squared plus the y-coordinate squared equals 1, which represents the equation of the unit circle. Therefore, this curve traces out the unit circle.
(c) Similarly, in the parametric curve (sin t, cos t), the x-coordinate is given by sin t and the y-coordinate is given by cos t. Again, by applying the trigonometric identity sin^2 t + cos^2 t = 1, we find that the equation of the unit circle is satisfied. Hence, this curve also traces out the unit circle.
(b) The parametric curve (sin 2t, cos t) does not trace out the unit circle. The x-coordinate is given by sin 2t, which has a period of π. As a result, the curve does not cover the entire unit circle.
(d) Similarly, the parametric curve (sin 2t, cos 2t) also does not trace out the unit circle. The x-coordinate is given by sin 2t, which has a period of π. Hence, the curve only covers half of the unit circle.

After answering the presented question, we can conclude that As a inequality result, the total of the next two numbers in the pattern is roughly 4.793 1011 + 9841.5 = 4.793 1011.
What is inequality?In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. Many simple inequalities can be solved by altering the two sides until just the variables remain. Yet, a lot of factors contribute to inequality: Negative values are divided or added on both sides. Exchange left and right.
Each succeeding number appears to be the cube of the previous number divided by 2. The next two numbers in the pattern, using this pattern, are:
\((27^3)/2 = 19683/2 = 9841.5\)
and
\((9841.5^3)/2 = 4.793 × 10^11\)
As a result, the total of the next two numbers in the pattern is roughly 4.793 1011 + 9841.5 = 4.793 1011.

For an economy the following functions have been given: C = 100 + 0.8Y S = -100 + 0.2Y I = 120 – 5r Ms = 120 Md = 0.2Y – 5r Calculate the following: (a). IS equation (5) (b). LM equation (5) (c). equilibrium level of income (5) (d) equilibrium level of interest rate.
Answers
To solve for the IS-LM equilibrium in an economy, we need to calculate the IS equation, LM equation, equilibrium level of income, and equilibrium level of interest rate. Given the functions for consumption (C), saving (S), investment (I), money supply (Ms), and money demand (Md), we can derive these values.
(a) IS equation:
The IS equation represents the equilibrium condition in the goods market. It is derived by equating national income (Y) with aggregate demand (C + I + G), where G represents government spending. In this case, the equation is:
Y = C + I
Substituting the given consumption and investment functions, we have:
Y = (100 + 0.8Y) + (120 - 5r)
Simplifying the equation, we get:
Y = 220 + 0.8Y - 5r
(b) LM equation:
The LM equation represents the equilibrium condition in the money market. It is derived by equating money supply (Ms) with money demand (Md). In this case, the equation is:
Ms = Md
Substituting the given money supply and money demand functions, we have:
120 = 0.2Y - 5r
(c) Equilibrium level of income:
To find the equilibrium level of income, we solve the IS equation for Y. Rearranging the IS equation from part (a), we get:
0.2Y = 220 - 5r
Y = (220 - 5r) / 0.2
(d) Equilibrium level of interest rate:
To find the equilibrium level of interest rate, we solve the LM equation for r. Rearranging the LM equation from part (b), we get:
5r = 0.2Y - 120
r = (0.2Y - 120) / 5
By substituting the equilibrium level of income (Y) into the LM equation, we can find the corresponding equilibrium level of interest rate (r). Similarly, by substituting the equilibrium level of interest rate (r) into the IS equation, we can find the corresponding equilibrium level of income (Y). These values represent the IS-LM equilibrium in the economy.

Answers
If ten workers are randomly selected, the probability exactly nine of them say that their jobs were sometimes or always stressful is 0.268 or 26.8%
The result of the recent poll is
80% of respondents said that their jobs were sometimes or always stressful
The 10 workers are randomly selected
Then we have to find the probability exactly nine of them say that their jobs were sometimes or always stressful
The equation
P(X) = nCx × P^x × (1-P)^n-x
Here n = 10
r = 9
P = 0.80
Substitute the values in the equation
P(9) = 10C9 × 0.80^9 × (1-0.80)^(10-9)
= 10 × 0.134 × 0.20
= 0.268
= 26.8%
Therefore, the probability exactly nine of them say that their jobs were sometimes or always stressful is 26.8%

a critical value, z subscript alphazα, denotes the _______.
Answers
A critical value, z subscript alpha (zα), denotes the boundary or cutoff point for a statistical test where the level of significance, also known as alpha (α), is set.
A critical value, z subscript alpha (zα), denotes the value at which the probability of observing a test statistic in the tail(s) of the sampling distribution equals the pre-determined significance level (alpha).
The critical value can be defined as the value that is compared with the parameter value in the hypothesis test to determine whether the null hypothesis will be rejected. If the value of the parameter is less than the critical value, the null hypothesis is rejected.
However, if the measured value is higher than the critical value, reject the null hypothesis and accept the alternative hypothesis. In other words, cropping divides the image into acceptable and unacceptable areas. If the value of the index falls within the rejection range, the rejection of the fact is rejected, otherwise the negative hypothesis is rejected.

suppose that the radius of convergence of the power series cn xn is r. what is the radius of convergence of the power series cn x9n ?
Answers
The radius of convergence of the power series $\sum_{n=0}^\infty c_n x^n$ is $r$. To find the radius of convergence of the power series $\sum_{n=0}^\infty c_n x^{9n}$, we can rewrite the series as $\sum_{n=0}^\infty c_n (x^9)^n$.
Letting $y = x^9$, we obtain the power series $\sum_{n=0}^\infty c_n y^n$, which has the same coefficients as the original series. By the ratio test, the series $\sum_{n=0}^\infty c_n y^n$ has radius of convergence $R' = r^9$. Therefore, the radius of convergence of the power series $\sum_{n=0}^\infty c_n x^{9n}$ is $r^9$.
