Answer:

probably would be 12x⁴, but I'm not 100% sure tho.

the left side of this equation equal the right side through the process of completing the square that establishes the equality between the left side and the right side of the Gaussian integral equation.

using  completing the square method:

Starting with the left side of the equation:

∫\(e^(^-^x^2)\) dx

\(e^(^-^x^2) = (e^(^-x^2/2))^2\)

∫\((e^(^-^x^2/2))^2 dx\)

let  u = √(x²/2) =  x = √(2u²).

dx = √2u du.

∫ \((e^(^x^2/2))^2 dx\)

= ∫ \((e^(^-2u^2)\)) (√2u du)

The integral of \(e^(-2u^2)\)= √(π/2).

∫ \((e^(-x^2/2))^2\) dx

= ∫  (√2u du) \((e^(-2u^2))\\\)

= √(π/2) ∫ (√2u du)

We substitute back  u = √(x²/2), we obtain:

∫ \((e^(-x^2/2))^2\)dx

= √(π/2) (√(x²/2))²

= √(π/2) (x²/2)

= (√π/2) x²

A comparison  with the right side of the equation  shows that they are are equal.

The average balance of the account is $1126.37.

An average is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group.

Consider the table that shows the balance (in dollars) of a bank account for three months.

Months            Account Balance

1                       $1285.12

2                       $961.36

3                       $1132.63

As we are aware, the following formula for the mean or average of any set of data:

Mean, \(\overline X=\frac{\sum X}{n}\)

where,  ∑X is the sum of all the observations in the data and n  is the number of observations in the data

Therefore, the average balance in the account is:

\(Average{~}balance=\frac{1285.12+961.36+1132.63}{3}\)

\(Average{~}balance=\frac{3379.11}{3}\)

Average balance = $ 1126.37

The meaning of \(\( \mathbb{N}=\bigcap \left \{X:X inductive \right \}\) is that the set of natural numbers is the intersection of all inductive sets.

The set of natural numbers is inductive because it satisfies both of these conditions. The set is non-empty because it contains the number 1. And if x is a natural number, then x+1 is also a natural number.

In other words, a set is inductive if it satisfies the following two conditions:

Step-by-step explanation:

Is the 3 to 2 part to part?  Out of every 5 people, 3 prefer pizza and 2 do not.  We can us this to set up a proportion.

3/5 = 120/x  The 3 represent the part that like pizza over the whole of 5.  The second ratio is showing the actual number of people that liked pizza over the total number of people.

What would be multiply 3 by to get 120? 40.  So, we will multiply 5 times 40 to get the total number of people.  5 x 40 = 200

a) The probability that exactly one of them will be a girl = 0.3407

b) The probability that at least one of them will like the football = 0.7672

a) If we select three students then the probability that exactly one of them will be a girl

From the attached two way table we can observe that the total number of girls = 22

the total number of boys = 18

and the total number of students = 40

The possible outcomes for selecting 3 students from 40 would be,

⁴⁰C₃

Using combination formula,

⁴⁰C₃ = 40! / (3! × (40 - 3)!)

      = 9880

If there is exactly one girl then other two must be boys in the set of 3 selected students.

So, the required probability would be,

P = (²²C₁ × ¹⁸C₂) / ⁴⁰C₃

P = (22 × 153)/9880

P = 0.3407

b) The number of students like the football = 15

and the number of students who don't like the football are 40 - 15 = 25

The probability that at least one of them will like the football would be,

P = (¹⁵C₃ × ²⁵C₀ + ¹⁵C₂ × ²⁵C₁ + ¹⁵C₁ × ²⁵C₂) / ⁴⁰C₃

P = ((455 × 1) + (105 × 25) + (15 × 300)) / 9880

P = 0.7672

y - 59 + 59 = 26 + 59

y = 85

Bill have to start with 85 stickers.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE have been given that Bill sold 36 stickers on the first day and 23 on the second day. He had 26 stickers left at the end of the second day.

Then the equation would be;

y - 36 - 23 = 26

y - 59 = 26

Subtract 59 from both the sides;

y - 59 + 59 = 26 + 59

y = 85

The first step is to find the values of x and y. From the information given,

x is the cost of an adult ticket and y is the cost of a child ticket. The system of equations is shown below

3x + 5y = 50

x + 5y = 31

From the second equation,

x = 31 - 5y

We would substitute x = 31 - 5y into 3x + 5y = 50. We have

3(31 - 5y) + 5y = 50

By expanding the parentheses, we have

93 - 15y + 5y = 50

- 15y + 5y = 50 - 93

- 10y = - 43

Dividing both sides of the equation by - 10,

- 10y/- 10 = - 43/- 10

y = 4.3

Substituting y = 4.3 into x = 31 - 5y, we have

x = 31 - 5 * 4.3 = 31 - 21.5

x = 9.5

If an adult ticket costs $9.5, then the cost of 4 adult tickets is

4 x 9.5 = $38

The answer is 459,461     These two do add to 920

Step-by-step explanation:

Remark

I'm going to make sure you are using consecutive odd numbers.

Let the smaller number = 2x - 1

Let the larger number = 2x + 1

Equation

2x - 1 + 2x + 1 = 920

4x = 920

x = 230

The consecutive numbers are 2*230 - 1 = 459

and 2*230 + 1                                             = 461

In the Middle Ages, alchemists pursued the goal of increasing the length of human life. They believed that by discovering the philosopher's stone, they could transmute base metals into gold and achieve immortality. Alchemists were interested in the transformation of substances, and they believed that this transformation could be applied to the human body as well.

In their pursuit of the philosopher's stone, alchemists experimented with various substances, such as mercury, lead, sulfur, and arsenic. They believed that these substances could be transformed into a more potent form, which could be used to cure diseases and extend human life.

Alchemists also believed that the human body was made up of four elements - earth, air, fire, and water - and that these elements needed to be balanced in order for a person to be healthy.

The alchemical quest for immortality had a profound influence on medieval culture. It inspired many literary works, such as the legends of the Holy Grail and the Fountain of Youth.

It also influenced the development of medicine, as alchemists were among the first to explore the use of chemicals to cure diseases.

Many of the substances that they discovered, such as antimony and sulfur, are still used in medicine today.The alchemical quest for immortality was ultimately unsuccessful.

However, it paved the way for the development of modern chemistry and medicine.

The alchemists' focus on the transformation of substances, and their belief in the healing power of chemicals, helped lay the foundations for modern pharmacology. They also inspired future generations of scientists and philosophers, who continued to explore the mysteries of the universe and the human body.

The Point estimate ± Margin of error =39 ± 3.3

Given, that in a survey, 29 people were asked how much they spent on their child's last birthday gift

n = 29 (sample size)

m = 39 (sample mean)

s = 18 (sample standard deviation)

C = 0.95 = 95% (confidence level)

Now, d = degrees of freedom = n-1 = 29-1 = 28

confidence level = 95%

Alpha value = 1 - (95/100) = 1 - (0.95) = 0.05

Then, the critical value is roughly

t = 1 - (Alpha value / 2)

t = 1 - (0.05/2)

t = 0.975

Then, the point estimate is the sample mean i.e. 39 which estimates the population mean.

And the margin of error (MoE) is

MoE = (t×s)/√n

MoE = (0.975×18)/√29

MoE = (0.975×18)/5.385

MoE = 17.55/5.385
