~Describe the transformation(s) shown:

According to the given statement 15600 possible options to a unique code.

A digit is a numerical unit of measurement and labeling in mathematics. The real numbers 1, 2, 3, 4, and so on constitute the first instances.

For the first password, we can choose any of the 26 numbers that are able, right? So for the first, we have 26 possible options.

For the second, we have 26 possible options minus 1 option which is already in use in the first password, so we have 26 -1 = 25 possible options here.

For the third, we also have 26 options, but we have to consider 2 unavailable options (1 in the first and 1 in the second), so we have 26 -2 = 24 options.

To finish it, we just have to multiply the possibilities of each lock:

26 * 25 * 24 = 15600 possible options to a unique code.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

the probability of winning at a certain gambling game is 0.1.

p=0.1

p(x) = (1-p)² *p

Answer:

the hat is $47.50.

Step-by-step explanation:

To determine the regular price of the hat, you can use the formula for calculating the sale price of an item, which is:

regular price * (1 - discount percentage) = sale price

In this case, we can set up the equation as follows:

regular price * (1 - 0.20) = $38

Solving for the regular price, we get:

regular price = $38 / (1 - 0.20)

regular price = $38 / 0.80

regular price = $47.50

Therefore, the regular price of the hat is $47.50.

Richard is 35 years old and Teo is 10 years old.

What is the linear function?

The difference between starting and final numbers is the percentage drop. It displays a percentage loss of value compared to the original regardless of the units. The difference between the initial and final amounts is the amount of decline.

We have,

Richard and Teo have a combined age of 48.

Richard is 15 years older than twice Teo's age.

Let the ages of Richard and Teo be R and T years old respectively.

R +T= 48    -----(1)

R= 2T + 15   -----(2)

Substitute (2) into (1):

2T +15 +T= 48

3T +15= 48

3T= 48 -15

3T= 33

T= 33 ÷ 3

T= 10.1

Substitute T= 10.1 into (2):

R= 2(10.1) +15

R= 20.2 +15

R= 35.2

R = 35

Hence, Richard is 35 years old and Teo is 10 years old.

The jewelry artist does not make a profit if she sells 15 necklaces at an art fair .

An inequality to show the number of necklaces, n, the artist must sell to make a profit is

12n - 135 > 4.50n , n > 15 .

We have given that

A jewelry artist is selling necklaces at an art fair.

Cost of rent a booth at the fair = $135

Cost of materials of each necklace= $4.50

Selling price of each necklace = $12

The inequality for the artist's profit is

12n>135+4.50n

where n --> number of necklaces

We have to check that if number of necklaces sold by artist are 15 then she make a profit or not .

For this we plug n = 15 and check the inequality is statisfied or not ,

12×15 > 135 + 4.50×15

=> 180 > 220 , which is not true.

So, the artist does not make a profit if she sells 15 necklaces.

She has profit when selling price is greater than cost price of necklaces.

If we take total number of necklaces are "n".

then, Total cost price of 15 necklaces= $4.50× n

= $4.50n

Total cost payed by artist = $4.50n+$135

Total selling price of 15 necklaces = $12n

Profit if S.P >C.P or $12n > $4.50n+$135

=> 12n - 135 > 4.50n , n > 15

Hence, the required inequality is that

What is Substitution ?

The algebraic approach to solving simultaneous linear equations is known as substitution technique. In this process, the value of one variable from one equation is substituted in the second equation, as the name indicates.

We'll use the idea of substitution in this case.

The given equation is:-

y = -0.625x² + 5x

where x = number of days

y = number of views per day in thousands

Let's check, number of views on day 1

x=1

y = (-0.625×1²) + (5×1) = 4.375 => 4375 views

For day 2

x=2

y=(-0.625×2²)+(5×2) = 7.5 => 7500 views

For day 3

x=3

y=(-0.625×3²)+(5×3) = 9.375  => 9375 views

For day 4

x=4

y=(-0.625×4²)+(5×4) = 10  => 10000 views

For day 5

x=5

y=(-0.625×5²)+(5×5) = 9.375  => 9375 views

For day 6

x=6

y=(-0.625×6²)+(5×6) = 7.5 => 7500 views  

For day 7

x=7

y = (-0.625×7²) + (5×7) = 4.375 => 4375 views

For day 8

x=8

y=(-0.625×8²)+(5×8) = 0  => 0 views

So, on day 8 there are 0 views, which means people will stop watching video after 7 days.

Answer:

Infinitives are a special form of verbs that can be used as a noun, adjective, or adverb. They are usually made by adding the word to before the base verb, and they can be useful when discussing actions without actually doing the action, such as “I want to go home,” or “To err is human.”

Step-by-step explanation:

The purpose of infinitives is to discuss an action in general instead of a specific instance of the action being done. For example, take a look at these two sentences:

I need to win.

Today, we win.

The first sentence uses the infinitive form of the verb win as a noun; the main verb of the sentence is actually “need.” The second sentence uses the standard form of win as an actionable verb. In the first sentence with the infinitive, the action of “winning” is not actually done; the sentence simply discusses the idea of winning.  The second sentence, however, describes the action of winning.

The effort needed to move an object along a curve that is specifically oriented. F(x, y) = (y, x) on the parabola y = 6x² from (0,0) to (2,24) is 48.

A bowl-shaped object is defined as having a curve at the surface created by the intersection of a cone and a plane that is perpendicular to a straight line. Another definition of a curve is one created when a moving point moves such that its distance from a fixed point equals its distance from a fixed line. A quadratic function is known in this form as its standard form. A parabola is a U-shaped curve that represents the quadratic function on a graph.

The given parabola is,

y = 6x²

Here consider x=t

Then,

The expected number of photons are [tex]N=1[/tex] × [tex]10^{3} m^{2}[/tex].

To put it simply, photons are basic subatomic particles that carry the electromagnetic force (and so much more). The photon is also the "quantum," or basic unit, of electromagnetic radiation.

Photons are all around us: Photons make up the light coming from the screen you're looking at, the X-rays doctors use to see bones, the radio in a car that sends out its signal, and the magnets on a refrigerator that support themselves.

Given: Total number of photons = 1 million

The graph represents the probability density of a photon being found (detected) along the horizontal x- axis.

Now, checking the graph, we will find that:

At x = 0.5, the probability of finding a photon is 1.

To get the probability density at 1 mm wide at the given x value, we will simply multiply the probability with the area under curve as follows:

[tex]P(x=0.5)[/tex] × area under curve

= [tex]1[/tex] × [tex]1[/tex] × [tex]10^{-3} m^{2}[/tex]

Now, we will get the expected number of photons as follows:

N = number of photons × area under curve

[tex]N=1[/tex] × [tex]10^{6}[/tex] × [tex]1[/tex] × [tex]10^{-3}[/tex]

[tex]N=1[/tex] × [tex]10^{3} m^{2}[/tex]
