If A is an n x n matrix and Ax = λx for some scalar λ, then x is an eigenvector of A. T/F
Answers
The definition of an eigenvector of A with eigenvalue λ.
If A is an n x n matrix and Ax = λx for some scalar λ, then x is an eigenvector of A. True or False?True.
By definition, an eigenvector of a matrix A is a non-zero vector x that satisfies the equation Ax = λx, where λ is a scalar called the eigenvalue corresponding to x.
So if Ax = λx for some scalar λ, then x is a non-zero vector that satisfies the definition of an eigenvector of A with eigenvalue λ.

Large-scale integrated (LSI) circuit chips are made in one department of an electronics firm. These chips are incorporated into analog devices that are then encased in epoxy. The yield is not particularly good for LSI manufacture, so the AQL specified by that department is 6% while the LTPD acceptable by the assembly department is 39%. Assume the company is willing to accept a consumer's risk of 10
percent and a producer's risk of 5 percent. Use Exhibit 10.16.
Find the sample size.
Answers
The sample size required is 29.
To find the sample size, we need to use the concept of Acceptable Quality Level (AQL) and Lot Tolerance Percent Defective (LTPD) along with the consumer's risk and producer's risk.
The AQL is the maximum percentage of defective items that the company is willing to accept from the LSI manufacture department, which is specified as 6%. On the other hand, the LTPD is the maximum percentage of defective items that the assembly department is willing to accept, which is specified as 39%.
To calculate the sample size, we can use the formula for the sample size in attribute sampling plans:
n = (\(Z^{2}\) * p * q) / \(E^{2}\)
Where:
n = sample size
Z = Z-value corresponding to the desired level of confidence (for consumer's risk of 10% and producer's risk of 5%, we can use Z = 1.65)
p = expected proportion of defective items (maximum between AQL and LTPD)
q = 1 - p
E = precision or tolerable error (difference between AQL and LTPD)
In this case, we want to determine the sample size, assuming the worst-case scenario. Therefore, we choose p as the maximum between AQL and LTPD, which is 39%. Hence, q is 1 - p, which is 61%. The precision or tolerable error (E) is the difference between AQL and LTPD, which is 39% - 6% = 33%.
Substituting these values into the formula, we have:
n = (\(1.65^{2}\) * 0.39 * 0.61) / (\(0.33^{2}\))
n ≈ 28.74
Since the sample size should be a whole number, we round up to the nearest whole number.
Therefore, the sample size required is approximately 29.

You would start by going backward. If 13 is 8 less, then you would first add 8. You would have 21. Now all you have to do is divide by three. So your answer would be 7. If you would want to check you could plug it back in. 7 multiplied by 3 is 21. 21 - 8=13

In a perfectly symmetrical bell-shaped "normal" distribution
a) the arithmetic mean equals the median.
b) the median equals the mode.
c) the arithmetic mean equals the mode.
d) All the above.
Answers
The correct response is d) All the above. The arithmetic mean is equal to the median, the median is equal to the mode, and the mode is equal to the arithmetic mean.
If the data are graphed symmetrically, the distribution demonstrates 0% skewness regardless of how long or fat the tails are. When the median of a data set is utilized, 50% of the data points in the collection have values lower than or equal to the median, and 50% of them have values greater than or equal to the median. The middle score in the set is known as the median. The first step in calculating the median is to order the data points from smallest to greatest. The median in an odd-numbered set will be the value that falls exactly in the middle of the list. You must determine the average of the two middle numbers in a set of even numbers. The average is determined by summing up each value individually and dividing that sum by the total number of observations.

Answer:
Step-by-step explanation:
This is an isosceles triangle because side AC and side AB are congruent (they are both marked with single slash marks). That means that angle B and angle C are also congruent. Angle B also measures 2x. To find the measure of each angle we will use the Triangle Angle-Sum Theorem:
x + 2x + 2x = 180 and
5x = 180 so
x = 36
Angle A = 36, B = 72 and C = 72
Answer:
x = 36 degrees
Step-by-step explanation:
This is an isosceles triangle, because two legs are equal. The angles opposite these legs are therefore also equal: <B = <C = 2x. The sum of the interior angles must be 180 degrees. Therefore,
x + 2x + 2x = 180 degrees, and 5x = 180 degrees. Thus, x = 36 degrees.
What are all the values of x that make the inequality 8 - 3x < 20 true?
Answers
Let's solve this inequality.
First of all, subtract 8 from both sides:-
\(\sf{-3x < 20-8}\)
\(\sf{-3x < 12}\)
Divide both sides by -3:-
\(\sf{x > -4}\)
Notice that the inequality sign changed...
Here's the rule:-
When you multiply/divide both sides by a negative number, you flip the inequality sign; so if we have "less than" it becomes "greater than" and so on...
So these are the values of x that will make the inequality true:-
\(\bigstar{\boxed{\pmb{The~numbers~greater~than~-4}}}\)
Well, -3 is greater than 4 :)
Let's plug it in and see if it makes the inequality true:-
-3>-4
Yes, it does make the inequality true :)

solve by iteration: (10) (i)t(n) = t(n-2) 2n t (1) = 1, t (0) = 0. (ii)t(n) = t(n-1) n/2 t (1) = 1.
Answers
By iteration, g(10) = 60 for (i) and g(10) = 14 for (ii)
Given information: The recursive formula are(i) t(n) = t(n - 2) + 2n, t(1) = 1, t(0) = 0(ii) t(n) = t(n - 1) + n/2, t(1) = 1.Solve by iteration:
1. The recursive formula is t(n) = t(n - 2) + 2n, t(1)
= 1, t(0)
= 0.
This can be written as, t(n) = t(n - 2) + 2nOr, t(n + 2) = t(n) + 2(n + 2) (Add 2(n + 2) to both sides)
Let, the initial value of t(n) be g(n)
Therefore, t(n + 2) = g(n + 2)g(n) + 2(n + 2)
This iteration will be used until the value converges to the answer.
2. The recursive formula is t(n) = t(n - 1) + n/2, t(1) = 1.
This can be written as, t(n) = t(n - 1) + n/2Or, t(n + 1) = t(n) + (n + 1)/2
Let, the initial value of t(n) be g(n)
Therefore, t(n + 1) = g(n + 1)g(n) + (n + 1)/2
This iteration will be used until the value converges to the answer.
3. t(0) = 0 and t(1) = 1.This is given.
The iterative method is used when no exact formula can be found that will provide the n-th term of the sequence directly.
The iteration for
(i) becomes, g(0) = 0,
g(1) = 1.g(2)
= g(0) + 2(2)
= 4g(3)
= g(1) + 2(3)
= 7g(4)
= g(2) + 2(4)
= 12g(5)
= g(3) + 2(5)
= 17g(6)
= g(4) + 2(6)
= 24g(7)
= g(5) + 2(7)
= 31g(8)
= g(6) + 2(8)
= 40g(9)
= g(7) + 2(9)
= 49g(10)
= g(8) + 2(10)
= 60
The iteration for
(ii) becomes, g(1) = 1.g(2)
= g(1) + (2)/2
= 2g(3)
= g(2) + (3)/2
= 3.5g(4)
= g(3) + (4)/2
= 5g(5)
= g(4) + (5)/2
= 6.5g(6)
= g(5) + (6)/2
= 8g(7)
= g(6) + (7)/2
= 9.5g(8)
= g(7) + (8)/2
= 11g(9)
= g(8) + (9)/2
= 12.5g(10)
= g(9) + (10)/2
= 14.
The values of g(n) converge to the corresponding values of t(n).
Therefore, the required answers are: g(10) = 60 for (i) and g(10) = 14 for (ii).

The expected value for a student to spend on lunch each day from the survey of 50 students is $5.18.
The expected value for a student to spend on lunch each day is derived from the survey of 50 students. This value is calculated by taking the total number of dollars spent by all of the surveyed students and dividing it by the total number of students surveyed. In this particular survey, the total number of dollars spent was $247, and the total number of students surveyed was 50. Dividing $247 by 50 gives us a value of $4.94. This value is then rounded up to the nearest cent to give us the expected value of $5.18. This expected value is the average amount of money that a student can expect to spend on lunch each day from the survey. It is important to note that this value is an estimate, as individual student spending habits may vary greatly.

\(y=\frac{1}{k}f(x-a)+b\)The required graph in the choices is that of the function:
\(y=\frac{1}{3}f(x+5)-3\)This equation shows that the new function translates the previous one vertically down by 3 units (b=-3).
Horizontally to the left by 5 units (a=-5), and a horizontal stretch by a factor of 3 (k=3).
Hence, the new graph will be the one that gives the old graph translated vertically downwards by 3 units, horizontally to the left by 5 units, and a horizontal stretch away from the y-axis by a factor of 3.
