Thus, the probability of the electron being in a spherical shell at distance (a) from the proton is e^(-a/a0), at distance (b) is e^(-b/a0), and at distance (c) is e^(-c/a0).

Probability is a metric for determining the possibility or chance of an event happening. It is a mathematical concept that measures the unpredictability of an occurrence and is frequently stated as a decimal or fraction. For example, if the probability of flipping a coin and obtaining heads is 0.5, there is a 50% chance of flipping heads. The number of favorable outcomes to the total number of potential outcomes is used to compute probability. In other words, it is the number of ways an event may occur divided by the total number of conceivable outcomes. Probability is used to make predictions and take wise decisions in a variety of disciplines, including mathematics, science, finance, and engineering.

How to solve?

If we assume the electron is in a hydrogen 1s orbital, the probability density function is given by the square of the 1s wavefunction, which is:

p(r) = (1/πa0^3) e^(-r/a0)

P(r, r+δr) = ∫p(r')dV = ∫p(r')4πr'^2dr'

For the given distances (a), (b), and (c), the probabilities are:

P(a) = ∫p(r')4πr'^2dr' = (1/πa0^3) ∫e^(-r'/a0)4πr'^2dr' = (1/πa0^3) * 4π * a0^3 * e^(-a/a0) = e^(-a/a0)

P(b) = e^(-b/a0)

P(c) = e^(-c/a0)

Since the side length is three units, the specified rectangular prism's volume will be 27 units.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

Answer:

t=2/f-5

Step-by-step explanation:

The measure of an exterior angle of a triangle is equal to the measure of its neighboring interior angle if both measure 90 degrees, according to the theory of supplementary angles.

If the sums of two angles equal 180 degrees, they are said to be supplementary.

However, two angles do not need to be near one another in order to be complementary.

If two angles' measures sum up to 180 degrees, they are said to be supplementary.

A triangle's outside angle complements the neighboring inner angle.

The adjacent internal angle will therefore likewise be 90 degrees if the exterior angle is.

Therefore, the measure of an exterior angle of a triangle is equal to the measure of its neighboring interior angle if both measure 90 degrees, according to the theory of supplementary angles.

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3,500 for their reception. If the reception hall charges a $50 cleanup fee plus $32 per person, find the greatest number of people that they may invite and still stay within their budget. James and Bethany can invite at most people to the reception. (Round down to the nearest whole person).

3,500 = 32p + 50

subtract 50 from both sides:

3,450 = 32p

divide both sides by 32:

p = 107.8125

because you cannot invite part of a person, round down to 107 people.

Answer:

Each shirt = $2.99, each pair of slacks = $5.99, and each sports coat = $6.99.

Total refers to a whole or full amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.

Let shirts equal SH, Slacks equal S, and sports coats equal SC.

2SH+2S equals 17.96.

6SH+3S+2SC=49.89

5SH+1SC=21.94

We'll use them to address

6SH+3S+2SC=49.89

-6SH-6S=--53.88, multiplying by -3 to eliminate SH.

-3S+2SC=-3.99

-30SH-6SC=-131.64, multiplying the third by -6 to eliminate SH

30SH+15S+10SC=249.45,multiplying by 5 to eliminate SH.

15S + 4SC = 117.81

Now 15S + 4SC = 117.81  and -3S+2SC=-3.99

S = $5.99

As a result, we may calculate SH as $2.99 and use the value of S and SH we get SC = $6.99

The change in the temperature after 4 1/4 hour is -6.8 C.

Given :

A freezer in a lab is set so that the temperature changes at a rate of –1.6 C every hour.

Temperature :

Temperature is the degree of hotness or coldness of an object.

The degrees must contain any units like kelvin , centigrade etc .

Change in temperature after 4 1/4 hours = change rate for hour * number of hours.

= -1.6 C * 4 1/4

= -1.6 C * 4.25

= -16 / 10 C * 425 / 100

= -16 * 425 / 10 * 100 C

According to the question, a builder needs to purchase nails in order to construct a house.

Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.

The contractor purchased 3 more small boxes than large boxes, hence it is assumed that he purchased an 'x' number of large boxes.

He purchased (x+3) small boxes.

So, 50(x+3) + 350(x) = 2950.

50x + 150 + 350x  = 2950.

400x = 2950 - 150.

400x = 2800.

x = 7.

Two terms are shown. However, the terms are like terms, so can be combined into one term:

Answer:

x = 2 , x = 5

Step-by-step explanation:

assuming you mean

[tex]\sqrt{9x-9}[/tex] = x + 1 ( square both sides to clear the radical )

([tex]\sqrt{9x-9}[/tex] )² = (x + 1)² ← expand using FOIL

9x - 9 = x² + 2x + 1 ( subtract 9x from both sides )

- 9 = x² - 7x + 1 ( add 9 to both sides )

0 = x² - 7x + 10 ← factor the quadratic

consider the factors of the constant term (+ 10) which sum to give the coefficient of the x- term (- 7)

the factors are - 2 and - 5 , since

- 2 × - 5 = + 10 and - 2 - 5 = - 7 , then

(x - 2)(x - 5) = 0

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 5 = 0 ⇒ x = 5

As a check

substitute these values into the equation and if both sides are equal then they are the solutions.

x = 2

left side = [tex]\sqrt{9(2)- 9}[/tex] = [tex]\sqrt{18-9}[/tex] = [tex]\sqrt{9}[/tex] = 3

right side = 2 + 1 = 3

left side = right side , so x = 2 is a solution

x = 5

left side = [tex]\sqrt{9(5)-9}[/tex] = [tex]\sqrt{45-9}[/tex] = [tex]\sqrt{36}[/tex] = 6

right side = 5 + 1 = 6

left side = right side, so x = 5 is a solution

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

the functions f(x) = (x+6)(x+2) and g(x) = x + 6

Equating them with each other

(x+6)(x+2) = x + 6

x+2 = 1
