As per the set theory, the number of student who take math course is 800

Set:

In math, set means an organized collection of objects and can be represented in set-builder form or roster form.

Given,

Here we know that suppose that all of the 1000 first-year students at a certain college are enrolled in a math or an English course. suppose 400 are taking both math and English and 600 are taking English.

Now, we need to find the number of students who take math course.

While looking into the given question we have identified that,

Total Number of students = 1000

Number of students in both course = 400

Number of students taking English = 600

Then the number of students who take math course is calculated as

=> 1000 - 600 + 400

=> 800

Therefore, the resulting number of students is 800.

Answer:

y = 554.55 minutes

Step-by-step explanation:

y = 5.5/10 x

y = 5.5/10 x 305

y = (5.5 x 305) / 10

y = 1677.5 / 10

y = 554.55 minutes

Answer:

It is given that:

The equation is:

y = (5.5/10)x

Here y represents the total time in minutes and x represents the number of pages read.

Plug x = 305

y = (5.5/10)(305)

y = 167.75 minutes

Thus, it will take 167.75 minutes to read a book that has 305 pages.

For an isosceles triangle has a base that measures 14 units, the length of each leg i.e y must be greater than or equal to 7 .

We have given that

let ABC is an isosceles triangle with base BC and AB = AC

The length of base of isosceles triangle, BC

= 14 units

Let "y" be the length of other side of triangle AB or AC

we have to find the possible length of y for each leg .

Using the Triangle inequality Theorem,

which states that the addition of any two sides of a triangle is greater than or equal to the third side; In symbols form , a + b ≥ c.

We have an isosceles triangle with base 14 cm

so, y + y ≥ 14

=> 2y ≥ 14

=> y ≥ 7

thus, the length of each leg of isosceles triangle must be greater than or equal to 7 units.

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:

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.

Adding 160 on both sides , we get

111x = 160

Divide by 111 on both sides , we get

x = 160/111

Now , substitute the value of x in equation (3) , we get

y = -15x/8

y = ( -15 x 160 ) / ( 111 x 8 )

y = -100/37

Therefore , the value of x is 160/111 and value of y is -100/37

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 shape of the cross section is a triangle. It is always triangle if the triangular pyramid sliced from any side perpendicularly to its base. See the picture in the attachment!

A pyramid is a polyhedron that has one base and lateral faces with the vertex at the top of the pyramid. The shape of lateral faces is always a triangle. While, the shape of the base varies and is used to name the pyramid.

A triangular pyramid is a pyramid with a triangular base. It has three lateral faces.

If a triangular pyramid is sliced by a plane from any side that is perpendicular to its base, the cross section formed will be a triangle. One line is at the base and two lines are at the lateral faces. See the picture in the attachment!

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
