False.

if A - λI has linearly dependent columns, then λ is an eigenvalue of A.

The statement is not true. In fact, the opposite is true: if A - λI has linearly dependent columns, then λ is an eigenvalue of A.

To see why, let's assume that A - λI has linearly dependent columns. This means that there exist non-zero constants c1, c2, ..., cn such that:

c1(A - λI)[:,1] + c2(A - λI)[:,2] + ... + cn(A - λI)[:,n] = 0

where [:,i] denotes the ith column of the matrix. We can rewrite this as:

(A(c1,e1) + A(c2,e2) + ... + A(cn,en)) - λ(c1,e1) - λ(c2,e2) - ... - λ(cn,en) = 0

where ei is the ith standard basis vector. This can be simplified to:

A(c1,e1) + A(c2,e2) + ... + A(cn,en) = λ(c1,e1) + λ(c2,e2) + ... + λ(cn,en)

or

A(c1,e1) + A(c2,e2) + ... + A(cn,en) - λ(c1,e1) - λ(c2,e2) - ... - λ(cn,en) = 0

which shows that λ is an eigenvalue of A, with corresponding eigenvector v = [c1, c2, ..., cn]^T.

Therefore, if A - λI has linearly dependent columns, then λ is an eigenvalue of A.

Answer:

The 3rd option

Step-by-step explanation:

The pattern is every 2 hours is $15 so 4 hours would be equal to $30

Since 4 hours would equal 30 and we need 12 hours multiplying both numbers by 3 would get you the answer

4x3=12

30x3=90

Making it equal

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

A situation in which conclusions based upon aggregated crosstabulation are different from unaggregated crosstabulation is known as Simpson's paradox.

Simpson’s Paradox is an example of statistics that can be wrong. The paradox is defined as averages that can be silly and misleading. Sometimes they can be just plain baffling.

It is also called the Yule-Simpson effect which is an effect that occurs when the marginal association between two categorical variables is qualitatively different from the partial association between the same two variables after controlling for one or more other variables.

This result is often encountered in social science and medical science statistics and is particularly problematic when frequency data are unduly given causal interpretations.

It is a statistical phenomenon where an association between two variables in a population emerges or reverses when the population is divided into subpopulations.

When words are strung together in speech, deviations from ideal pronunciation can occur due to various factors such as coarticulation, assimilation, elision, and reduced vowel sounds.

When words are spoken in rapid succession, coarticulation plays a significant role in shaping the pronunciation of individual words. Coarticulation refers to the influence of neighboring sounds on the production of a particular sound. For example, in the phrase "black cat," the /k/ sound in "black" may be influenced by the following /k/ sound in "cat," resulting in a slight modification or assimilation of the sound.

Assimilation occurs when sounds become more similar to nearby sounds. For instance, in the phrase "handbag," the /n/ sound in "hand" may assimilate to the /b/ sound in "bag," making it nasal (as in "hambag") or even causing complete elision of the /n/ sound. Elision refers to the omission or deletion of sounds, often in unstressed or weak positions, such as the reduction of the /ə/ vowel sound in "a" or "the" to a schwa sound, as in "uh" or "thuh."  

Additionally, when words are strung together, certain vowel sounds may be reduced or shortened to accommodate the natural rhythm of speech. This reduction can result in changes to the stress patterns and lengths of vowels within words. Overall, these deviations from ideal pronunciation in connected speech are a natural part of spoken language and contribute to the fluidity and efficiency of communication.

Answer:

Let's use the equation:

Total earnings = Base pay + Commission

Xavier's base pay is $150 per day, and his commission is x percent of his daily sales, which is $1250 in this case. Therefore, we can write the equation as:

$200 = $150 + (x/100) * $1250

Simplifying the equation:

$200 - $150 = (x/100) * $1250

$50 = (x/100) * $1250

Dividing both sides by 1250:

0.04 = x/100

Multiplying both sides by 100:

x = 4

Therefore, the commission percentage for Xavier on that day was 4%.

The given difference equation is Yt = 2Yt-1 + 1, with the initial condition Y0 = 9. To analyze the time path of the variable, we can calculate the values of Yt for different time periods.

Using the given equation and initial condition, we can find the value of Y1:\(Y1 = 2Y0 + 1 = 2(9) + 1 = 19\)Next, we can find the value of Y2:
\(Y2 = 2Y1 + 1 = 2(19) + 1 = 39\) Continuing this pattern, we can find the values of Y3, Y4, and so on. However, instead of calculating all the values manually, we can observe a pattern: Yt = 2Yt-1 + 1 .

By substituting Yt-1 into the equation repeatedly, we can see that the value of Yt will keep increasing as t increases. This means that the time path of the variable Yt diverges, meaning it does not converge to a specific value.

In this case, the

coefficient

of Yt−1​ is 2, which is greater than 1. Therefore, the time path of the variable Y diverges.

In summary, the time path of the variable Y, given by the difference

equation

Yt​=2Yt−1​+1 with the initial condition Y0​=9, diverges. The coefficient of Yt−1​ in the difference equation allows us to determine whether the path will diverge or converge.

The given difference equation is Yt​=2Yt−1​+1, with the initial condition Y0​=9.

To analyze the time

path

of the variable, we can use this equation to calculate the value of Y at different time points.

Let's calculate the value of Y at different time points:

Y1​=2Y0​+1=2(9)+1=19
Y2​=2Y1​+1=2(19)+1=39
Y3​=2Y2​+1=2(39)+1=79

Continuing this pattern, we can calculate Y4​, Y5​, and so on. As we can see, the values of Y are increasing at each time point.

This suggests that the variable is diverging, or growing without bound.

In general, the time path of a

variable

in a difference equation can be determined by examining the coefficients in the equation.

If the coefficient of Yt−1​ is greater than 1, the variable will diverge.

If it is less than 1, the variable will converge towards a certain value.

If it is equal to 1, the variable will neither diverge nor converge, but oscillate.

Step-by-step explanation:

Given that Lisa earns a salary of $11.40 per hour at the video rental store and she is paid weekly. Occasionally, she has to work overtime for more than 50 hours but less than 60 hours. For working overtime she is paid at 1.5 times the hourly rate.

When Lisa works overtime, she is paid at 1.5 times her hourly rate for each hour of overtime she works. Since she earns $11.40 per hour, her overtime rate will be:$11.40 x 1.5 = $17.10

Therefore, for each overtime hour, Lisa will be paid $17.10 per hour. Since Lisa works more than 50 hours but less than 60 hours,

we can calculate her overtime pay by using the following formula:

Total overtime pay = (Total overtime hours) x (Overtime pay rate)Total overtime hours = Number of overtime hours worked - 50Total overtime pay = ((Number of overtime hours worked - 50) x $17.10)Let's say Lisa works 55 hours in a week. This means she worked 5 hours of overtime.

Therefore, her overtime pay will be:Total overtime pay = ((55 - 50) x $17.10)Total overtime pay = (5 x $17.10)Total overtime pay = $85.50Hence, Lisa earns $85.50 in overtime pay when she works 55 hours a week.
