For merging two sorted lists of sizes m and n into a sorted list of size m+n, we required comparisons of
A O(m+n)
B O(m)
C O(n)
D O(logm + logn)
The merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons.
The merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons. This is because we must compare each element in both lists in order to sort them. So a total of m+n comparisons are required in the worst case scenario.
This can be visualized by using a formula: n + m = m+n. This formula can be used to calculate the total number of comparisons required.
For example, if m = 10 and n = 15, then 10 + 15 = 25. This means that 25 comparisons would be required in order to sort the two lists.
Thus, the merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons. This is because we must compare each element in both lists in order to sort them.
The merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons.

Solve each of the linear systems in Problems 13 through 20 to determine whether the critical point (0, 0) is stable, asymptotically stable, or unstable. Use a computer system or graphing calculator to construct a phase portrait and direction field for the given system. Thereby ascertain the stability or instability of each critical point, and identify it visually as a node, a saddle point, a center, or a spiral point. dx/dt = -2x, dy/dt = -2y
Solve linear system: dx/dt = -2x, dy/dt = -2y. Analyze stability using phase portrait & direction field, identify type of critical point.
The given linear system is:
dx/dt = -2x
dy/dt = -2y
To find the stability or instability of the critical point (0, 0), we need to analyze the behavior of the solutions near that point. To do so, we can linearize the system around (0,0), which means we approximate the system with its tangent line at (0,0). The linearized system is given by:
dx/dt = -2x
dy/dt = -2y
The eigen values of the linearized system are -2 and -2. Since both eigenvalues are negative, the critical point (0,0) is a stable node, which means that any solution that starts close to (0,0) will converge to (0,0) as t approaches infinity. The phase portrait of the system is a set of arrows pointing towards the origin, indicating that all solutions converge to (0,0) as time goes on.

The value of n is 8.
What is Binomial Theorem?Binomial theorem is the method of expanding an expression consisting of two terms raised to any power.
Using the expansion of Binomial theorem, we can write,
(2 + 3x)ⁿ = ⁿC₀ (2)ⁿ (3x)⁰ + ⁿC₁ (2)ⁿ⁻¹ (3x)¹ + ⁿC₂ (2)ⁿ⁻² (3x)² + ⁿC₃ (2)ⁿ⁻³ (3x)³ + ⁿC₄ (2)ⁿ⁻⁴ (3x)⁴ + .............
Coefficient of x³ is ⁿC₃ (2)ⁿ⁻³ (3)³ and the coefficient of x⁴ is ⁿC₄ (2)ⁿ⁻⁴ (3)⁴.
Ratio of these coefficients is 8 : 15.
[ⁿC₃ (2)ⁿ⁻³ (3)³] / [ⁿC₄ (2)ⁿ⁻⁴ (3)⁴] = 8 / 15
Simplifying,
(4 × 2) / [(n - 3) 3] = 8/15

Which ordered pair is included in the solution to this system?
A (−6, 3.5)
B (−6, −3)
C (−4, 3)
D (−4, 4)
Answer:
Option B)
Step-by-step explanation:
The inequalities are y ≥ (2/3)x + 1 and y < (-1/4)x + 2 and (−6, −3) satisfied the inequality.
What is inequality?
A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given phrase,
y is greater than or equal to two-thirds times x plus 1 ⇒ y ≥ (2/3)x + 1
y is less than negative one-fourth times x plus 2 ⇒ y < (-1/4)x + 2
Substitute, point (−6, −3)
-3 ≥ (2/3)(-6) + 1
-3 ≥ -3
Substitute in second inequality,
-3 < (-1/4)(-6) + 2
-3 < 7/2
Hence "The inequalities are y ≥ (2/3)x + 1 and y < (-1/4)x + 2 and (−6, −3) satisfied the inequality".

If x must be a number. The same outcome is obtained by increasing x by 20% as well as by decreasing that product of four with x by 5. x has the value of 25/14.
Explain about the inequalities of the equation?According to the issue, if we decreased that product of four with x by five, we would obtain the same result as increasing x by 20%. Finding equations for these two scenarios will allow us to set them equal and then solve for x.Let's look up an expression for raising x by 20%. This might be shown as x + 20%. x = x + 0.2x = 1.2x = 6x/5.
Let's come up with a formula to reduce that product of four with x by five. The first step is to determine the 4x, or the product of 4 and x.Then, since we need to reduce this by 5, we must remove 5 from 4x, which is equal to 4x - 5.The two expressions must now be set to be equal to each other.
6x/5 = 4x - 5
Add 6x/5 to both sides and subtract. To make 4x and 6x/5 have a similar denominator, we can rephrase 4x as 20x/5.
0 = 20x/5 - 6x/5 - 5 = 14x/5 - 5
0 = 14x/5 - 5
We can now increase both sides by five.
5 = 14x/5
Now that we have the reciprocal of 14/5, 5/14, we may multiply either sides by this number.
5(5/14) = (14x/5)(5/14) = x
25/14 = x
Thus, the solution is 25/14.

What is Inequality?Using the terms greater than, larger than or equal to, less than, or less than or equal to as a declaration of the order connection between two integers or algebraic expressions is known as inequality. Economic inequality comes in many forms, most notably wealth inequality measured by the distribution of wealth and income inequality measured by the distribution of income (the amount of money people are paid) (the amount of wealth people own). There are significant forms of economic inequality amongst various groups of people in addition to economic disparity between nations or states.
Given:
We know that she first descends 22 feet, and then she descends at a rate of 22 feet per minute. Basically, we have 22 feet which have to me summed with 22x, which expresses the ratio per minute, where x is minutes, and these terms cannot be more than 93 feet, so there are equal or less than 93 feet.
The expression would be
22 + 22x ≤ 93
If we solve this, we have,
22 + 22x ≤ 93
22x ≤ 93 - 22
22x ≤ 71

how many square units are in the area of the enclosed region in the diagram? all angles pictured are right angles.
The area of the enclosed region in the diagram is 20 square units.
The area of the enclosed region in the diagram can be calculated using the formula A = lw, where A is the area, l is the length, and w is the width. The length is 5 units and the width is 4 units, so A = lw = 5 X 4 = 20 square units.
To calculate the area, we first need to find the length and width of the enclosed region. The length can be found by measuring the longest side, which is the bottom side. This side has a length of 5 units. The width can be found by measuring the shorter side, which is the left side. This side has a width of 4 units.
Once we have the length and width, we can use the formula A = lw to calculate the area. In this case, A = 5 X 4 = 20 square units. Therefore, the area of the enclosed region in the diagram is 20 square units.

What is the power of a power rule?The power of a power rule is used when a single base is elevated to multiple exponents.
Then the simplified expression is obtained keeping the base, while the exponents are multiplied.
The numerator is simplified as follows:
25^(-4) = 5²^(-4) = 5^(2 x -4) = 5^(-8).
The denominator is given as follows:
5²^(-2) = 5^(-4).
When two terms have the same base and different exponents and are divided, we keep the base and subtract the exponents, hence:

Thirty students in the School of Business were asked what their majors were. The following represents their responses (M = Management; A = Accounting; E = Economics; O = Others). Construct a frequency distribution and a bar chart. Construct a relative frequency distribution and a pie chart.
To construct frequency and relative frequency distributions, count number of students for each major and divide by total number of students (30) to find the relative frequency.
Use the frequency and relative frequency data to create a bar chart and a pie chart to visualize the data. To construct a frequency distribution and bar chart for the thirty students in the School of Business, we need to count the number of occurrences of each major and create a table. For example, if 9 students chose Management as their major, 9 would be the frequency for Management. We can then plot the frequencies on a bar chart, with each major on the x-axis and its frequency on the y-axis. The bar chart visually represents the distribution of the data.
A relative frequency distribution is a frequency distribution expressed as a proportion or percentage of the total number of observations. To create a relative frequency distribution, we divide each frequency by the total number of students (30 in this case) and multiply by 100%. The relative frequencies can then be used to construct a pie chart, where each major is represented as a wedge or slice of the pie, proportional to its relative frequency. The pie chart visually represents the distribution of the data as a whole.

Solve the following equation algebraically: 3 x squared = 48
Answer:
x=16/squared
Step-by-step explanation:
divide each term in 3xsquared = 48 by 3squared and simplify.
Answer:
If squaring a number means multiplying it by itself, according to this rule, you multiply 3 by "x" and then multiply "x" by itself to get 48. In this scenario, you divide 3 by blank squared to get blank. In this case, you set up this problem with division, so we are dividing 3 times blank squared by 3. Whatever the blank value is, we know this equation equals 48, so you must create a mirrored equation of 48 divided by 3. Now that you've divided 48 by 3, that is 16, right? So 16 will be the equivalent of blank squared, or "x" squared. For blank squared, since we are dealing with algebra, the next step is to use square roots using what we know. We know that 16 is composed of 4 squared, right? So turn 4 squared into a radical of √4². This radical is equal to 4, because "radical" = "number" as long as that number is more than or equal to 0. So, in conclusion, x is 4.

it is true in practice, we frequently use a continuous distribution to approximate a discrete one when the number of values the variable can assume is countable but large.
The continuous category of random variables refers to those whose spaces are unions of intervals or intervals rather than a countable number of points. When the sample size is too big to treat each individual event discretely or when a variable does not occur in discrete intervals, continuous distributions are employed as probability models (please see Discrete Distributions for more details on discrete distributions). The main distinction between continuous and discrete distributions is that, while discrete distributions deal with smaller sample populations and cannot be treated as if their random variable values are on a continuum (from negative infinity to positive infinity), continuous distributions deal with a sample size so large that its random variable values are treated on a continuum (from negative infinity to positive infinity).
