A) 12 and 33 can be divided by 3 so 12:33 = 4:11
B= 20 and 5 can be divided by 5 so 20mm:5mm = 4mm:1mm
Answer:
A. 4: 11
B. 4: 1
Step-by-step explanation:
What are these? These are ratios, which show proportion. For example, for every two dogs, there is one cat. They can be written as words, fractions, or with colons, such as in these problems.
How to simplify: To simplify, think of the highest common factor. If you can't think of the highest, just think of a factor both numbers have in common and keep going until the numbers don't have any factors in common.
In this case, for A, the common factor was 3. 12/3=4 and 33/3=11. This cannot be simplified further because 11 is prime, which means it has no factors besides 1 and 11.
For B, the common factor was 4, so it is 4:1.

Pythagoras lived over 2500 years ago. What is his theorem and why do we still use it today?
Answer:
The Pythagorean Theorem is helpful for two-dimensional navigation. You can use it along with two lengths to calculate the shortest path. The lengths north and west will be the triangle's two wings, and the diagonal will be the shortest line separating them. The same principles can be used for air navigation. He is best known in the modern day for the Pythagorean Theorem, a mathematical formula which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.

Bill has 29 more apps on his phone than Sherri, and they have a total of 99 apps. How many apps does each person have?
Sherri has 35 apps on her phone and Bill has 64 apps on his phone.
Let's represent Sherri’s apps with x.
Then, the number of Bill's apps will be x+29 (since he has 29 more apps than Sherri).
Their total number of apps is 99.Thus, the mathematical equation is:x + (x+29) = 99
Simplifying this equation gives:2x + 29 = 99
Subtracting 29 from both sides of the equation gives:2x = 70
Dividing both sides by 2 gives:x = 35
This means Sherri has 35 apps on her phone.
Substituting that into x+29 gives:35+29 = 64
Therefore, Bill has 64 apps on his phone.
Hence, each person has Sherri has 35 apps on her phone and Bill has 64 apps on his phone. The total number of apps between the two of them is 99 apps.

In a simple random sample of 170 households, the sample mean number of personal computers was1.71. Assume the population standard deviation is σ=0.86.
(a) Construct a 90% confidence interval for the mean number of personal computers. Round the answer to at least two decimal places.
A 90% confidence interval for the mean number of personal computers is _______
(b) If the sample size were 120 rather that 170, would the margin of error be larger or smaller than the result in part (a)? Explain.
The margin of error would be _______, since __________in the sample size will _______ the standard error.
(c) If the confidence levels were 95% rather than 90%, would the margin of error be larger or smaller than the result in part (a)? Explain.
The margin of error would be _______, since __________ in the confidence level will ___________the critical value za/2.
(d) Based on the confidence interval constructed in part (a), is it likely that the mean number of personal computers is greater than 1?
It ________ likely that the mean number of personal computers is greater than1.
The confidence interval using a 90% confidence level is (1.601, 1.819)
Confidence IntervalConfidence Interval = Sample Mean ± Margin of Error
Given the parameters:
Sample Mean (x) = 1.71
Population Standard Deviation (σ) = 0.86
Sample Size (n) = 170
Confidence Level = 90%
The standard Error(SE) is given by:
SE = σ / √n
SE = 0.86 / √170 ≈ 0.0663
The margin of Error is related to standard error by the relation:
ME = Z × SE
ME = 1.645 × 0.0663 ≈ 0.109
Confidence Interval = Sample Mean ± Margin of Error
Confidence Interval = 1.71 ± 0.109
Confidence Interval= (1.601, 1.819)
Part B:A decrease in sample size from 170 to 120 would lead to increase in error margin , since decrease in sample size will increase the standard error.
Part C:If confidence interval were raised from 90% to 95% , the error margin would be larger since increase in confidence interval would increase the critical value
Part D :Based on the confidence interval , it is very likely that the mean number of personal computers is greater than 1.

2. Find the inverse Laplace transform. ( 3pts each) 2 1 4 a. F(s) b. F(s) - 52 -28-3 S S
Inverse Laplace transform of f(s) = s³ / (s² + 6s + 13) is
[tex]f(t) = [(-3 + 2i)^{13} / (2i)] e^{(-3 + 2i)t} + [(-3 - 2i)^{13} / (-2i)] e^{(-3 - 2i)t[/tex]
The inverse Laplace transform of f(s) = s¹³ / (s² + 6s + 13) needs to be found.
To find the inverse Laplace transform, we first need to factor the denominator of f(s) using the quadratic formula:
s² + 6s + 13 = 0
s = [-6 ± √(6² - 4(1)(13))] / 2(1)
s = -3 ± 2i
Now we can rewrite f(s) as:
f(s) = s¹³ / [(s + 3 - 2i)(s + 3 + 2i)]
Using partial fraction decomposition, we can write:
f(s) = A / (s + 3 - 2i) + B / (s + 3 + 2i)
where A and B are constants to be determined. Multiplying both sides by the denominator, we get:
s¹³ = A(s + 3 + 2i) + B(s + 3 - 2i)
Substituting s = -3 + 2i, we get:
(-3 + 2i)¹³ = A(2i)
Solving for A, we get:
A = (-3 + 2i)¹³ / (2i)
Similarly, substituting s = -3 - 2i, we can solve for B:
B = (-3 - 2i)¹³ / (-2i)
Now we can write f(s) as:
f(s) = [(-3 + 2i)¹³ / (2i)] / (s + 3 - 2i) + [(-3 - 2i)¹³ / (-2i)] / (s + 3 + 2i)
Taking the inverse Laplace transform of each term separately using the table of Laplace transforms, we get the final answer:
[tex]f(t) = [(-3 + 2i)^{13} / (2i)] e^{(-3 + 2i)t} + [(-3 - 2i)^{13} / (-2i)] e^{(-3 - 2i)t[/tex]

Step-by-step explanation:
Use the distance formula to find the radius of the circle with the two coordinates given. The radius of this circle is about 37.2. Plug 37.2 into the formula 2(pi)r to find the Circumference. The answer is 233.7 rounded to the nearest tenth.
there may be several different min-cut sets in a graph. using the analysis of the randomized min-cut algorithm, argue that there can be at most n(n − 1)/2 distinct min-cut sets.
The randomized min-cut algorithm, such as the Karger's algorithm, is an iterative algorithm that repeatedly contracts edges in a graph until only two nodes (or a small number of nodes) remain. At that point, the remaining edges represent a cut in the graph.
In each iteration of the algorithm, an edge is chosen uniformly at random to be contracted. This contraction merges the two nodes connected by the chosen edge into a single super-node. The process continues until only two nodes remain, representing the cut in the graph.
To analyze the algorithm, let's consider a graph with n vertices. At each iteration, the number of vertices decreases by one since two vertices are merged into one. Therefore, after k iterations, there are n - k vertices remaining in the graph.
Now, let's consider the number of distinct cuts that can be formed by the remaining vertices. For n vertices, the total number of possible cuts is [tex]2^(n-1)[/tex]since each vertex can be on one side of the cut or the other. However, some of these cuts may be identical because the order in which the vertices are contracted can change the representation of the cut.
To see why, suppose we have a set of vertices A and a set of vertices B. The order in which the vertices are contracted can result in different representations of the cut. For example, if we contract vertex A before vertex B, the cut might be represented as (A, B). However, if we contract vertex B before vertex A, the cut might be represented as (B, A). Both cuts are essentially the same, but the order of the vertices determines the representation.
Since there are (n-1) edges that need to be contracted to reach the final cut of two vertices, there are (n-1)! possible orders in which the vertices can be contracted. However, each order produces the same cut, so we need to divide by (n-1)! to account for the different representations.
Therefore, the number of distinct cuts that can be formed by the remaining vertices is [tex]2^(n-1)[/tex]/ (n-1)!. Simplifying this expression, we get:
[tex]2^(n-1) / (n-1)! = n(n-1)(n-2)...(2)(1) / (n-1)(n-2)...(2)(1) = n[/tex]
So, there can be at most n distinct min-cut sets in the graph.
In summary, using the analysis of the randomized min-cut algorithm, we can argue that there can be at most n(n - 1)/2 distinct min-cut sets.

An object located at the point (4, 55) on a distance time graph is later located at the point (9, 45). If distance is in metres and time is in seconds, the average speed is: a) -2 m/s b) 5 m/s c) -5 m/s d) 2 m/s
An object located at the point (4, 55) on a distance time graph is later located at the point (9, 45). If distance is in metres and time is in seconds, the average speed is -2 m/s.
To calculate the average speed of an object, we need to find the total distance traveled divided by the total time taken.
Given that the object is located at the point (4, 55) initially and later located at the point (9, 45), we can determine the total distance traveled and the total time taken.
Total distance traveled = Difference in distance = 45 - 55 = -10 meters (negative because the object moved from a higher distance to a lower distance)
Total time taken = Difference in time = 9 - 4 = 5 seconds
Average speed = Total distance traveled / Total time taken = -10 meters / 5 seconds = -2 meters/second
Therefore, the average speed of the object is -2 m/s.
Option (a) -2 m/s is the correct answer.

Step-by-step explanation:
With the teachers starting salary being $40,000, we can rightfully assume that it their salary would not increase with Choice A, $40,000 * 0.2 = $800.
2% otherwise known as 0.02, would make the teachers yearly salary $40,000 * 1 + 0.02, or $40,000 * 1.02. Making the correct answer, Choice B - (1.02). (This would also give the teacher an additional $800 per year!)

The sequence continues as follows:2, 5, 11, 21, 36, 67, ...
Given sequence2 5 11 21 36...
First differences 3 6 10 15...
Second differences 3 4 5...
Third differences 1 1...
The third differences are constant, which means that we can use a cubic polynomial for the fitting.
The formula for a cubic polynomial is
an³ + b
n² + c
n + d
Let us denote the nth term of the sequence by fn. Then, we have
f1 = 2, f2 = 5, f3 = 11, f4 = 21, f5 = 36...
We can write a system of equations using the first four terms of the sequence.
2 = a + b + c + d
5 = 8a + 4b + 2c + d
11 = 27a + 9b + 3c + d
21 = 64a + 16b + 4c + d
Solving this system, we get a = 1/3, b = 1, c = 11/3, and d = 0.
Thus, the closed-form expression for the nth term of the sequence isf(n) = (1/3)n³ + n² + (11/3)n
The next term in the sequence is f(6) = (1/3)(6)³ + (6)² + (11/3)(6) = 67.

Transition: (ε, ε, ε) -> Accepting state
State 2: Secondary state
