There are 48 such students who did not know any of the three languages.

Given,

   Since we have given that

   Number of students were taken for survey n(U)= 100

  Number of students who know French n(F) = 30

  Number of students who know German n(G) = 19

  Number of students who know Russian n(R) = 16

 Number of students who know both French and Russian n(F∩ R) = 11

 Number of students who know both German and French n(G ∩ F) = 12

 Number of students who know both Russian and German n(R ∩ G) = 6

Number of students who know all three languages = 4

So, n(F∪G∪R)=n(F)+n(G)+n(R)-n(F∩G)-n(F∩R)-n(G∩R)+n(F∩G∩R)

 n(F∪G∪R)=30+19+16-12-11-6+4

 n(F∪G∪R)=52

 So, the number of students who do not know any of the three languages is

[tex]n ( F ∩ G ∩ R )' = n (U) - n ( F ∩ G ∩ R )\\n ( F ∩ G ∩ R )' = 100- 52\\\\n ( F ∩ G ∩ R )' = 48[/tex]

The total number of free throws shots Andres made was 8 and the total number of two point shots Andres made was 4.

First, let us understand the variables:

Any number, vector, matrix, function, its argument, set, or one of its elements can be specifically represented by a variable.

Let x and y be the quantity of shorts.

x is the number of attempts at the free throw line.

y is the quantity of two-point attempts.

According to the question, we have;

x + 2y = 16 ............equation 1

x + y = 12    ............equation 2

From equation 2 we can take out the value of x;

x = 12 - y     ............equation 3

substituting the value of x in equation 1, we will get;

(12 - y) + 2y = 16

12 - y + 2y = 16

12 + y = 16

y = 16 - 12

y = 4

putting the value of y in equation 3, we will get

x = 12 - 4

x = 8

Thus, the total number of free throws shots Andres made was 8 and the total number of two point shots Andres made was 4.

The three types of proof are:

(i) Proof by Induction

(ii) Direct Proof

(iii) Proof by Contradiction

Proof by Induction:

Proof by induction is the proof in which we generalize a particular for the entire equation.

In the inductive step we generalize the conclusion from the basis, where we prove the equation for a particular value for the entire theorem or equation.

On solving this, if the answer observed follows the theorem used then it is proven

Proof by Contradiction:

In this type of proof we take a contradicting equation to the one that has to be proven. If this equation when further solved turns out to be false or untrue, the equation is considered proven.

Direct Proof:

In the direct proof we assume that the given equation or theorem, to be proven is correct. We then go on to slow the question with the given assumption. If the on solving the answer comes out to be correct, we say that the theorem has been proven.

A firm has two plants (X and Y) producing the same product which sells for $12 each. The total profit at plant X and plant Y are equal if the volume of each plant is 2,000 units.

To solve the problem, first translate the given problem into equations.

The formula for profit is:

profit = revenue from sales - total cost

total cost = fixed cost + variable cost

revenue = selling price x number of units sold

Let:

x = the number of units sold in plant X

y = the number of units sold in plant Y

From the problem, we can conclude:

Profit X = profit Y

x = y

Profit X = 12x - (5000 + 3x)       (equation 1)

Profit Y = 12 y - (7000 + 2y)      (equation 2)

Substitute y = x into equation 2

Profit Y = 12 x - (7000 + 2x)  

Hence,

12x - (5000 + 3x)  = 12 x - (7000 + 2x)  

3x - 2x = 7000 - 5000

x = 2,000

G = U(20), order of each element of G = ?

The smallest positive power of an element that gives you your identity is the order of the element in a group. Three instances are covered: complex numbers, a 2x2 rotation matrix, and real number elements of finite order.

G = U(20) = {1,3,7,9,11,13,17,19}

⇒ 3° ≡ 1, 3¹ ≡ 3, 3² ≡ 9, 3³ ≡ 7, 3¹ ≡ 1(20)

∴ order of 3 = 4

7⁴ ≡ 1 (mod 20) → order (7) = 4

9² ≡ 1 (mod 20) → order (9) = 2

11² ≡ 1 (mod 20) → order (11) = 2

13² ≡ 9(mod 20) → 13⁴ ≡ 81(mod 20) → 13⁴ ≡ 1 (mod 20)

⇒ order (13) = 4

order  07 = 4

17 ≡-3(mod 20) ⇒ 17² ≡ yy (mod 20)

Given, a curve with the points represented by

x = t²-23 and y = t³ + t, at t = 5

we have to find an equation of the line tangent to the curve at the given point on the curve.

so, the given point is (x , y) = (5² - 23 , 5³ + 5)

(x , y) = (2 , 130)

Now, the slope of the curve at that point be,

dy/dx = (3t² + 1)/(2t)

dy/dx = 76/10

Now, on using the slope-intercept form, we get

(y - 130)/(x - 2) = 38/5

5(y - 130) = 38(x - 2)

5y - 650 = 38x - 76
