B) Quick Sort is algorithms sorts data by recursively splitting the array into smaller sub-arrays, until eventually reaching single-element sections, and then joins the sub-arrays back together in sorted order
What is Merge Sort Algorithm?Merge Sort is an effective algorithm for sorting the data items of a list or an array. This algorithm's fundamental idea is to break the unsorted list into many sub-lists until every sub-list contains only one item.
The merging procedure then recombines all of the sublists, resulting in a sorted list. Divide-and-conquer is the name given to this merging process. Merge Sort divides the original list into N sublists, each of which contains one element.
The Merge Sort algorithm is faster than other sorting algorithms when it comes to time complexity. The time complexity of Merge Sort is O (n log n), which is better than Bubble Sort and Insertion Sort.
It is a more efficient sorting algorithm than other algorithms, such as bubble sort, which has a higher time complexity of O (n²).
Therefore, we can say that Merge Sort is the most efficient algorithm to sort an array in ascending or descending order.

Find the expected value of the winnings
from a game that has the following
payout probability distribution:
The expected probability distribution is $4.35
We must multiply each supplied chance by the respective payout value in order to determine the expected value.
As a result, we have the payout probability distribution shown below:
0.35(1) + 2(0.2) + 5(0.1) + 8(0.2) + 10(0.15) (0.15)
= 0.35 + 0.4 + 0.5 + 1.6 + 1.5

In Rosettenville, a suburb of Johannesburg, South Africa, Robert Brozin and Fernando Duarte acquired the Chicken Land restaurant in 1987, launching Nando's.
The eatery was renamed Nando's in honor of Fernando. The restaurant incorporated influences from former Mozambican Portuguese colonists, many of whom had relocated to Johannesburg's southeast after their country gained independence in 1975. Expansion was an essential component of their vision from the beginning. Nando's had already grown from one restaurant in 1987 to four by 1990. It became increasingly difficult to implement a common strategy and decision-making became inefficient as new outlets were maintained as separate businesses.
In 1995, Nando's International Holdings (NIH) was established as a new international holding because managing this growingly complex global structure had become extremely challenging. The South African branch of Nando's Group Holdings (NGH) was successfully listed on the Johannesburg Stock Exchange on April 27, 1997. NGH was 54% owned by NIH, with the remaining 26% available to the general public and former joint venture partners. The main goals of the share offer and listing were to broaden the group's capital base and enable group restructuring.

To rewrite the quadratic equation 9 = -3x^2 -18x - 25 in the form y = a(x - p)^2 + q, we need to complete the square. First, we factor out the leading coefficient of -3:
-[tex]3(x^2 + 6x + 25/3) = -3(x^2 + 6x + 9 + 16/3)[/tex]
Next, we add and subtract 9 inside the parentheses to complete the square:
[tex]-3(x^2 + 6x + 9 - 9 + 16/3) = -3((x + 3)^2 - 1/3)[/tex]
Simplifying the expression further, we get:
[tex]-3(x + 3)^2 + 3 = y[/tex]
Comparing this to the standard form y = a(x - p)^2 + q, we can see that a = -3, p = -3, and q = 3. Therefore, the value of p is -3.
Please hit brainliest if this helped!
Answer:
[tex]p = - 3[/tex]Step-by-step explanation:
To find:-
The value of p .Answer:-
We are here given that a quadratic equation is written in the form of y = a(x-p)² + q and we are interested in finding out the value of "p" .
So , the given quadratic equation to us is ,
[tex]\longrightarrow y = -3x^2-18x-25\\[/tex]
Now complete the square on the RHS side of the equation as ,
Firstly make the coefficient of x² as 1 . This can be done by taking out -3 as common.
[tex]\longrightarrow y = -3\bigg(x^2+6x +\dfrac{25}{3}\bigg)\\[/tex]
we can rewrite it as ,
[tex]\longrightarrow y = -3\bigg( x^2+2(3)(x) +\dfrac{25}{3}\bigg) \\[/tex]
Add and subtract 3² , as ;
[tex]\longrightarrow y = -3\bigg( x^2+2(3)(x) + 3^2-3^2+\dfrac{25}{3}\bigg) \\[/tex]
Rearrange the terms as ,
[tex]\longrightarrow y = -3 \left\{ (x^2+2(3)(x) + 3^2) - 9 +\dfrac{25}{3}\right\} \\[/tex]
Notice the terms inside the small brackets are in the form of [tex]a^2+b^2+2ab[/tex] which is the whole square of [tex] (a+b)[/tex] . Hence , we can write it as ,
[tex]\longrightarrow y =-3\bigg\{ (x+3)^2 + \dfrac{-27+25}{3}\bigg\} \\[/tex]
Simplify,
[tex]\longrightarrow y = -3\bigg\{ (x+3)^2 -\dfrac{2}{3}\bigg\} \\[/tex]
Open the curly brackets by multiplying the terms inside the brackets by -3 as ,
[tex]\longrightarrow y = -3(x+3)^2 - 2 \\[/tex]
Now compare it with [tex] y = a(x-p)^2+q [/tex] . On comparing we get ,
[tex]\longrightarrow \boxed{\boldsymbol{ p =-3}}\\[/tex]
Hence the value of p is -3 .

To find the current that supplies the maximum wattage, we need to take the derivative of the power function with respect to I, set it equal to zero, and solve for I. The derivative of the power function is:
dW/dI = 120 - 24I
Setting this equal to zero and solving for I, we get:
120 - 24I = 024I = 120I = 5
Therefore, the current that supplies the maximum wattage is 5 amps. We can verify that this is a maximum by checking the second derivative of the power function with respect to I. The second derivative is:
d^2W/dI^2 = -24Since the second derivative is negative, the function has a maximum at I = 5.
Please hit brainliest if this helped!
Answer:
We can find the current that supplies the maximum wattage by finding the value of I that maximizes the power function W(I) = 120I - 12I^2.
To do this, we can take the derivative of W with respect to I and set it equal to zero:
dW/dI = 120 - 24I = 0
Solving for I, we get:
I = 5
Therefore, the current that supplies the maximum wattage is 5 amps.

According to the given circle, the measure of the arc is option C. 21°.
Let's look at the figure provided. Since arc AC has a measure of 84°, we know that angle AOC, which is the central angle that subtends arc AC, has a measure of 84° as well. We can use this information to find the measure of angle AOB, which is an inscribed angle that includes angle ABC.
Since arc AC is 84°, arc AB must have a measure of 180° - 84° = 96°. This means that angle AOB, which spans arc AB, must have a measure of half of 96°, or 48°.
Now we can use the property of inscribed angles to find the measure of angle ABC. We know that angle AOB is twice the measure of angle ABC, so angle ABC must have a measure of half of 48°, or 24°.
Therefore, the answer is C. 21°.

Boys - 1/3 of 2/5 = 2/15
6/25+2/15=28/75
Calculate total number of students
If 28/75 = 280
280/28=10
10x75=750
Total number of students = 750

Step-by-step explanation:
so, it is a geometric sequence (every new term is created by multiplying the previous term by a fixed constant.
in this case this constant is 2.
a1 = 3
a2 = 3×2 = 6
a3 = a2×2 = a1 × 2×2 = 3×4 = 12
so, we see
an = 3 ×2^(n-1)
or
an+1 = 3 × 2^n
Answer:
[tex]A_n=3 \cdot 2^{n-1}[/tex]
Step-by-step explanation:
A recursive formula for a sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.
Given recursive rule:
[tex]\begin{cases}A_1=3\\A_{(n+1)}=2A_n\end{cases}[/tex]
According to the recursive formula, each term in the sequence is double the previous term. This means the sequence is geometric with the common ratio, r = 2.
An explicit formula for a sequence allows you to find the nth term of the sequence. The explicit formula for a geometric sequence is:
[tex]\boxed{A_n=A_1 \cdot r^{n-1}}[/tex]
where:
A₁ is the first term.r is the common ratio.Substituting the given value of A₁ and the found value of r into the formula, the explicit formula for the given sequence is:
[tex]A_n=3 \cdot 2^{n-1}[/tex]
This can also be written as:
[tex]A_{(n+1)}=3 \cdot 2^{n}[/tex]
