The major assumption in factor analysis (but not PCA) is that the observed variables are caused by a smaller number of underlying, unobserved (latent) variables, which are called factors.

Factor analysis and principal component analysis (PCA) are both techniques used for data reduction and dimensionality reduction. However, they differ in their assumptions and goals.

In factor analysis, the focus is on identifying the underlying latent variables (called factors) that explain the observed correlations among a set of variables. The major assumption in factor analysis is that the observed variables are caused by a smaller number of underlying factors. These factors cannot be directly measured, but are inferred from patterns of correlations among the observed variables. The goal of factor analysis is to extract these factors and to estimate how much each factor contributes to each observed variable.

In contrast, PCA is a technique that focuses on finding a linear combination of the original variables that explain the maximum amount of variance in the data. The major assumption in PCA is that the observed variables are not caused by any underlying factors, but are simply linearly related to each other. The goal of PCA is to find a set of orthogonal (uncorrelated) principal components that capture the maximum amount of variance in the data.

Therefore, the major assumption in factor analysis (but not PCA) is that there are underlying latent variables (factors) that cause the observed correlations among the variables.

Step-by-step explanation:

Thus, the correct answer is: C. The Stafford loan will have a lower balance of $431.17 at the time of repayment.

In order to evaluate the Unsubsidized Stafford Loan against the PLUS Loan, a comparison of their balances upon repayment after 6 months of graduation is necessary.

Having taken out a loan of $9,529 with an annual interest rate of 5.95% compounded monthly, and after an interest accumulation period of 18 months, the Stafford Loan balance at this point in time stands roughly around $10,365.86.

On the other hand, the PLUS Loan's equilibrium at graduation is recorded at $10,172.23, but including a 6-month interest accumulation period along with an annual incrementation percentage of 6.55% that is compounded monthly equals to approximately $10,797.03 when due for repayment.

To summarize, based on the balance comparisons, it is concluded that the Stafford loan owes a lower amount at repayment which is different by $431.17 compared to the PLUS Loan.

Step-by-step explanation:

The equation of the line is y = mx+b where m represents the slope.

Since x has no coefficent, m must equal to 1.

Answer:

The answer is B!

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 63000 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 63000, so we can write it down as 100%=63000.

4. We know, that x% equals 17000 of the output value, so we can write it down as x%=17000.

5. Now we have two simple equations:

1) 100%=63000

2) x%=17000

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=63000/17000

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17000 is what percent of 63000

100%/x%=63000/17000

(100/x)*x=(63000/17000)*x       - we multiply both sides of the equation by x

100=3.7058823529412*x       - we divide both sides of the equation by (3.7058823529412) to get x

100/3.7058823529412=x

26.984126984127=x

x=26.984126984127

The money owed by the cashier after selling three shirts and two sweatshirts for $203.75 and 6% clothing tax is $215.975.

The percentage tax is the tax amount charged for the item. The tax amount is given by dividing the per cent by 100 and multiplying it by the total amount of the item.

The total cost of three shirts and two sweatshirts is $203.75 and the tax is 6%.

The tax amount will be,

Tax amount = \(\frac{6}{100}\times203.75\)

\(=12.225\)

So, the total money owed by the cashier will be,

Total money owed by cashier \(=203.75+12.225\)

= $215.975

Therefore, the money owed by the cashier after selling three shirts and two sweatshirts is $215.975.

The solution for the given problem is (a) P(X ≥ 20,000) = 0.4493, P(X ≤ 30,000) = 0.7769, P(20,000 ≤ X ≤ 30,000) = 0.3276. (b) P(X > 75,000) = 0.0821, P(X > 100,000) = 0.0183.

Solution: a) To find the probability that a randomly selected fan will last at least 20,000 hours. P(X ≥ 20,000). Now, Mean time until failure is 25,000 hours which is given and is represented by µ. Hence, µ = 25,000 hrs. The parameter used for the Exponential distribution is λ.λ = 1 / µλ = 1 / 25,000 hrs. λ = 0.00004. Therefore, the probability that a randomly selected fan will last at least 20,000 hours. P(X ≥ 20,000) =  e -λt = e -0.00004 × 20,000 ≈ 0.4493The probability that a randomly selected fan will last at least 20,000 hours is 0.4493.

To find the probability that a randomly selected fan will last at most 30,000 hours. P(X ≤ 30,000) = 1 - e -λt = 1 - e -0.00004 × 30,000 ≈ 0.7769. The probability that a randomly selected fan will last at most 30,000 hours is 0.7769.

To find the probability that a randomly selected fan will last between 20,000 and 30,000 hours. P(20,000 ≤ X ≤ 30,000) = P(X ≤ 30,000) - P(X ≤ 20,000)P(20,000 ≤ X ≤ 30,000) = (1 - e -λt) - (1 - e -λt)P(20,000 ≤ X ≤ 30,000) = e -0.00004 × 20,000 - e -0.00004 × 30,000 ≈ 0.3276. The probability that a randomly selected fan will last between 20,000 and 30,000 hours is 0.3276.

b) To find the probability that the lifetime of a fan exceeds the mean value by more than 2 standard deviations.

z = (X - µ) / σZ = (X - µ) / σ = (X - 25,000) / (25,000)λ = 1 / µλ = 1 / 25,000 hrs. λ = 0.00004

The formula for z is z = (X - µ) / σ => X = z σ + µ

The standard deviation of the Exponential distribution is σ = 1 / λσ = 1 / 0.00004 = 25,000 hrs

Z = (X - µ) / σ = (X - 25,000) / (25,000)Z > 2z > 2 => (X - 25,000) / (25,000) > 2 => X > 75,000 hrs.

Now, the probability that the lifetime of a fan exceeds the mean value by more than 2 standard deviations.

P(X > 75,000) = e -λt = e -0.00004 × 75,000 ≈ 0.0821

The probability that the lifetime of a fan exceeds the mean value by more than 2 standard deviations is 0.0821

To find the probability that the lifetime of a fan exceeds the mean value by more than 3 standard deviations.

Z > 3z > 3 => (X - 25,000) / (25,000) > 3 => X > 100,000 hrs.

Now, the probability that the lifetime of a fan exceeds the mean value by more than 3 standard deviations P(X > 100,000) = e -λt = e -0.00004 × 100,000 ≈ 0.0183

The probability that the lifetime of a fan exceeds the mean value by more than 3 standard deviations is 0.0183.

Answer:

We know that:

She makes $19 per hour of lifeguarding.

She makes $8 per hour walking dogs.

She can work at most 7 hours per week.

She must earn a minimum of $80 per week.

If x represents the number of hours lifeguarding and y represents the number of hours walking dogs, the inequalities will be:

x + y ≥ 7 hours.

(this says that she can work at most 7 hours per week)

x*$19 + y*$8 ≥ $80

(this says that she can earn a minimum of $80)

Then the system of inequalities is:

x + y ≥ 7 hours.

x*$19 + y*$8 ≥ $80

To graph these two we can write them as lines in standard form and simply graph both inequalities, the solution of the system will be the intersection between the solutions of each inequality.

Here we also should add the inequalities:

x ≥ 0

y ≥ 0

So we only look at the first quadrant.

Answer:

2.537 x 10¹⁵ miles

Step-by-step explanation:

We are given the following:

1 light year = 5.9 x 10¹² miles

Distance of the star = 4.3 x 10² light years

To get this we just convert the distance of the star in light years into miles.

We cancel out the light years and then we are left with:

In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.

Coefficients:

4.3 x 5.9 = 25.37

Exponents of 10:

10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴

Then we combine them again to form a scientific notation:

25.37 x 10¹⁴

But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.

The answer will then be:

2.537 x 10¹⁵ miles

It is memoryless because the output at a given time index n does not depend on any past or future inputs. The system is linear because the output is a product of the input signal and a constant. It is also time-invariant because the system's behavior remains unchanged over time.

c) The system y[n] = |x[n]| is causal since the output at any time index n only depends on the current and past input values.

Step-by-step explanation:

but if the y intercept is 0 then it’ll show like: y= 3x which is equal to y=3x plus or minus 0

No, a piecewise function does not always have an x and y intercept.

A piecewise function is a function that is defined by multiple sub-functions, each of which applies to a certain interval of the main function's domain.

An x-intercept is the point where the function crosses the x-axis, and a y-intercept is the point where the function crosses the y-axis.

It is possible for a piecewise function to not have an x or y intercept if none of the sub-functions cross the x or y axis. For example, the piecewise function f(x) = {2x + 1 for x < 0, -2x + 1 for x > 0} does not have an x or y intercept because neither of the sub-functions cross the x or y axis.

In conclusion, a piecewise function does not always have an x and y intercept. It depends on the sub-functions that make up the piecewise function.

Answer:

Bus 18 is more consistent than Bus 47 based on the IQR, which is smaller for Bus 18 (16) compared to Bus 47 (24), indicating less spread of data between the 25th and 75th percentiles.

Step-by-step explanation:

Answer: The correct option regarding which bus has the least spread among the travel times is given as follows:

Bus 14, with an IQR of 6.

How to obtain the measures of spread?

First, we consider the dot plot, which shows the number of times that each observation appears in the data set.

Then we consider the interquartile range, which gives the difference between the third quartile and the first quartile of the data set.

The interquartile range is a better measure of spread compared to the range of a data set, as it does not consider outliers.

For groups of 15 students, we have that:

The first half is composed of the first seven students, hence the first quartile is the fourth dot, which is the median of the first half.

The second half is composed of the last seven students, hence the first quartile is the eleventh dot, which is the median of the first half.

The quartiles for Bus 14 are given as follows:

Q1 = 12.

Q3 = 18.

Hence the IQR is of:

IQR = Q3 - Q1 = 18 - 12 = 6.

The quartiles for Bus 18 are given as follows:

Q1 = 9.

Q3 = 16.

Hence the IQR is of:

IQR = Q3 - Q1 = 16 - 9 = 7.

The limit of f(x) as x approaches 0 exists and is equal to -47/50 where

\(h(x)=−14 {x}^{3} −32{x}^{2}−94{x}^{3}\)

Since g(x) ≤ f(x) ≤ h(x) for -2 ≤ x ≤ 2, we will utilize the squeeze theorem, to discover the constraint of f(x) as x approaches 0.

Agreeing with the press hypothesis, in the event that g(x) ≤ f(x) ≤ h(x) for all x in a few interims containing a constrain point c.

and in case the limits of g(x) and h(x) as x approaches c rise to, at that point, the constrain of f(x) as x approaches c moreover exists and is rise to the common constrain of g(x) and h(x).

In this case, we have:

\( - 1 \leqslant \sin( \frac{\pi}{2} {(x)}^{2} ))^{3} \leqslant \frac{ - 1}{4 {x}^{3} } - \frac{3}{2 {x}^{2} } - \frac{47}{50} \\ for - 2\)

Taking the limit as x approaches 0 on both sides of the above inequality, we get:

\( - 1 \leqslant lim(x = 0) \sin( \frac{\pi}{2} {(x)}^{2} )^{3} ) \leqslant lim(x = 0)( \frac{ - 1}{4x^{3} - \frac{3}{2 {x}^{3} } }) - \frac{47}{50} \)

The limit on the right-hand side can be found by evaluating each term separately:

\(lim(x = 0) \frac{ - 1}{4 {x}^{3} } = 0 \\ lim(x = 0) \frac{ - 3}{2 {x}^{2} } = 0\)

lim (x→0) -47/50 = -47/50

Therefore, the limit of f(x) as x approaches 0 exists and is equal to -47/50:

\(lim(x = 0)f(x) = lim(x = 0) \sin( \frac{\pi}{2} ( {x}^{2})^{3} = \frac{ - 47}{50} ) \)

hence, we have shown that the function f(x) defined by g(x) ≤ f(x) ≤ h(x) for -2 ≤ x ≤ 2 approaches a limit of -47/50 as x approaches 0.

No, events a and b are not disjoint if if the p(a) = 0.25 and the p(b) = 0.5.

Two events are considered disjoint if they cannot occur at the same time, meaning their intersection is equal to zero. Mathematically, if A and B are disjoint events, then P(A ∩ B) = 0.

In this case, we do not know whether events a and b are independent or dependent. Therefore, we cannot determine whether they are disjoint based on the given probabilities alone.

To determine whether events a and b are disjoint, we need to know whether they share any common outcomes. If there are any outcomes that belong to both events, then the events are not disjoint.
