While implementing the bubble sort algorithm, the maximum number of comparisons that can take place for n elements are [tex]\frac{n(n -1)}{2}[/tex]

When an array or list of items has to be rearranged, a sorting algorithm is used to compare the elements and sort the elements in the array or list. In each data structure, the new order of the items is determined using the comparison operator.

The simplest sorting method is called Bubble Sort, and it involves periodically exchanging nearby components if they are arranged incorrectly. Since the average and worst-case time complexity of this approach is relatively high, it is not appropriate for huge data sets.

According to the condition the maximum number of comparison can be found as follows:

Number of elemnts = n

Number of passes required by bubble sort of n elements will be = n-1

Therefore for the maximum number of comparisons that can take place for n elements will be = [tex]\frac{n(n -1)}{2}[/tex]

The solution of the equation p = √2 - p is as follows: p = 1 and p = -2

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. Therefore, let's solve the equation as follows;

let's solve for the variable p in the equation

p = √2 - p

square both sides

p² = (√2 - p)²

p² = 2 - p

p² + p - 2 = 0

The equation forms a quadratic equation.

Therefore,

p² + p - 2 = 0

p² - p + 2p - 2 = 0

p(p - 1) +2(p - 1) = 0

(p - 1)(p + 2) = 0

Hence,

p = 1 and p = -2

Answer:

Angles of the triangle are 90°, 50.77° and 39.23°.

Step-by-step explanation:

For any positive integer n, 1 × 1! + 2 × 2! + . . . + n × n! = (n + 1)! - 1

We use mathematical indution technique to prove  1 × 1! + 2 × 2! + . . . + n × n! = (n+1)! - 1, for  a positive integer n.

Let T(n) be the given expression  1 × 1! + 2 × 2! + . . . + n × n! = (n+1)! - 1

For n = 1,

1 × 1! = 1

and (1 + 1)! - 1 = 1

This means T(1) is true.

Assume that T(k) is true.

So, 1 × 1! + 2 × 2! + . . . + k × k! = (k + 1)! - 1

We need to prove T(k + 1) is also true.

i.e., to prove: 1 × 1! + 2 × 2! + . . . + (k + 1) × (k + 1)! = ((k + 1) + 1)! - 1

Consider,

1 × 1! + 2 × 2! + . . . + (k + 1) × (k + 1)!

= 1 × 1! + 2 × 2! + . . . + k × k! + (k + 1) × (k + 1)!

= (k + 1 )! - 1 + (k + 1) × (k + 1)!

= (1 + k + 1)(k + 1)! - 1

= (k + 2)(k + 1)! - 1

= (k + 2)! - 1

= ((k + 1) + 1)! - 1

This means, T(k+1) is also true.

So, ​T(n) is true for all positive integers n .

Hence proved.

Emma could use the expression 300(1.15)^t to calculate her amount using a compound interest rate every year.

We know that Compound interest, also known as interest on principal and interest, is the process of adding interest to the principal amount of a loan or deposit.

The interest one earns on  the previous interest is known as compound interest.

For eg - if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year.

We will have $110.25 at the end of the second year.

Now, here we know that:

Interest rate = 15%

Now, compound interest formula is given by

A = P(1 + r/n)^nt

Upon putting the values, we get 300(1.15)^t.

Therefore, Emma could use the expression 300(1.15)^t, to calculate the amount using a compound interest rate every year.

Answer:

Step-by-step explanation:

4x - 16 = 2x + 6

4x - 2x = 6 + 16

2x = 22

x = 11

-------------------------------

check

4 × 11 - 16 = 2 × 11 + 6

44 - 16 = 22 + 6

28 = 28

Answer: x=11

Step-by-step explanation:

4x-16=2x+6

Start by combining like terms cancelling out the smaller one.

4x(-2x)-16=2x(-2x)+6

Then cancel out -16 so you get the variable x by itself.

2x-16(+16)=6(+16)

Then divide both sides by 2 to get x value.

2x/2=22/2

Integrate (ax)2 − b2 3/2 with respect to x. The result is (2/5)ax5/2 − (b2/5)x3/2 + c, where c is the constant of integration.

Integrate (ax)2 − b2 3/2 with respect to x.

First, use the power rule to rewrite the integrand as

(2/5)ax5/2 − (b2/5)x3/2.

Next, use the integration by parts formula to integrate the expression:

∫(2/5)ax5/2 − (b2/5)x3/2 dx

= (2/5)ax5/2 − (b2/5)x3/2 + c,

where c is the constant of integration.

Integrating (ax)2 − b2 3/2 with respect to x involves using the power rule and the integration by parts formula. The power rule states that when integrating a function to the nth power, the exponent is reduced by one and the coefficient is multiplied by the original exponent divided by the reduced exponent. Therefore, the integrand is rewritten as (2/5)ax5/2 − (b2/5)x3/2. The integration by parts formula is then used to integrate the expression, resulting in (2/5)ax5/2 − (b2/5)x3/2 + c, where c is the constant of integration.

The dataset is quantitative and continuous.

Quantitative data is gathered by measuring and counting. Qualitative data is collected by interviewing and observing. Quantitative data is analyzed using statistical analysis, while qualitative data is analyzed by grouping it in terms of meaningful categories or themes. Quantitative data is anything that can be counted or measured; it refers to numerical data. Qualitative data is descriptive, referring to things that can be observed but not measured—such as colors or emotions.

Discrete data and continuous data are both types of quantitative data. The main difference between them is the type of information they represent. Discrete data typically only shows information for a particular event, while continuous data often shows trends in data over time. The type of data that has clear spaces between values is discrete data. Continuous information is information that falls into a continuous series. Discrete data is countable. Continuous data is measurable. There are distinct or different values in discrete data.

Since calories may be represented by numbers, the data set calories burnt will always have a numerical value. So, it is a quantitative piece of information.

The trigonometric functions are SinƟ = 0.6, CosƟ = 0.8, Tan Ɵ = 0.75, Cot Ɵ = 1.33,  Sec Ɵ = 1.25, Csc Ɵ  = 1.67.

The point (4,3) is on the terminal side of an angle in standard position, and the associated triangle’s missing hypotenuse can be determined using the Pythagorean Theorem, which is:

hyp^2 = adj^2 + opp^2

Hence,

hyp^2 = 4^2 + 3^2 = 16 + 9 = 25

hyp = √25 = 5

Using the provided information, where opposite side is 3, adjacent side is 4, and hypotenuse is 5, the six trigonometric functions can be determined as

1. SinƟ = Opposite/Hypotenuse = 3/5 = 0.6

2. CosƟ = Adjacent/Hypotenuse = 4/5 = 0.8

3. Tan Ɵ = Opposite/Adjacent = ¾ =0.75

In Analysis of variance,  X (bar) is not affected by whether or not the population means are equal.

Analysis of variance  is a statistical method for examining differences in means. It consists of a number of statistical models and the accompanying estimating techniques (such as the "variation" within and between groups). Ronald Fisher, a statistician, created Analysis of variance. The rule of total variance, on which the Analysis of variance is based, divides the observed variance in a given variable into components owing to various causes of variation.

ANOVA generalizes the t-test beyond two means by offering a statistical test to determine if two or more population means are equal. In other words, the Analysis of variance is employed to determine whether two or more means differ from one another.
