what is 1/4 + 1 plus 3/4 - 2/3 - 1/2

Answers

Answer 1

5/6 is the value of the expression.

To solve this expression, we need to find a common denominator for all the fractions:

1/4 + 1 + 3/4 - 2/3 - 1/2

= 1/4 + 3/4 + 1 - 2/3 - 1/2 (adding the fractions with common denominators)

= 4/4 + 1 - 8/12 - 6/12 (finding equivalent fractions with common denominators)

= 1 + 1/3 - 1/2 (simplifying)

To add 1/3 and -1/2, we need to find a common denominator of 6:

1 + 1/3 - 1/2

= 6/6 + 2/6 - 3/6 (finding equivalent fractions with common denominators)

= 5/6 (simplifying)

Therefore, the value of the expression is 5/6.

A person bets 1 dollar to b dollars that he can draw two cards from an ordinary deck of cards without replacement and that they will be of the same suit. Find b so that the bet is fair.

Answers

Answer:

$3.25

Step-by-step explanation:

In an ordinary deck of cards, we will notice that there are 52 cards.

However, we have 4 suits and 13 cards in each one making a total of 52, right?.

So, the probability that a person draws two cards and they will be of the same   suit is:

\(P(X) =\dfrac{ \bigg (^4_1 \bigg) \times \bigg ( ^{13}_{2}\bigg) }{ \bigg ( ^{52}_{2} \bigg)}\)

\(P(X) =\dfrac{ \dfrac{4!}{1!(4-1)!} \times \dfrac{13!}{2!(13-2)!} }{ \dfrac{52!}{2!(52-2)!} }\)

\(P(X) =\dfrac{4}{17}\)

Given that; A person bets 1 dollar to b dollars;

To make the bet fair is;

\(\dfrac{4}{17}b - \dfrac{13}{17}(1) = 0\)

\(= \dfrac{4}{17}b = \dfrac{13}{17}\)

multiply both sides by 17

4b = 13

b = 13/4

b = 3.25

Therefore, to make the fair, the value of b need to be $3.25

Using the expected value formular, the value of b such that the game is fair is 3.25

Total number of cards in a deck = 52

Number of cards per suit = 13

Number of suits = 4

Selection without replacement :

Club = C ; Spade = S ; Heart = H ; Diamonds = D

(C and C) or (H and H) or (S and S) or (D and D)

[(13/52 × 12/51) + (13/52 × 12/51) + (13/52 × 12/51) + (13/52 × 12/51)] = 0.2353

Probability of not selecting a card of the same suit :

1 - 0.2353 = 0.7647

For game to be fair :

Σ[(X × P(X)] = 0

X : ______ b _____ - 1

P(X): __ 0.2353__ 0.7647

[(0.2353b + (-1 × 0.7647)] = 0

0.2353b - 0.7647 = 0

0.2353b = 0.7647

Divide both sides by 0.2353

b = 0.7647 / 0.2353

b = 3.249

b = 3.25

Hence, the value of b is 3.25

(a) Show that if λ is an eigenvalue of A, then λ is an eigenvalue of \(A^{T}\). Show with an example that the eigenvectors of A and \(A^{T}\) are not the same.

(b) Show that if λ is an eigenvalue of A, and A is invertible, then λ^-1 is an eigenvalue of A^-1.

Answers

If λ is an eigenvalue of A, then λ is an eigenvalue of \(A^T\). Show with an example that the eigenvectors of A and \(A^T\) are not the same.

What are eigenvalues and eigenvectors?

The equation Av = λv, where v is a non-zero vector, is satisfied by an eigenvector v and an eigenvalue given a square matrix A. In other words, the eigenvector v is multiplied by the matrix A to produce a scalar multiple of v. Due to their role in illuminating the behaviour of linear transformations and differential equation systems, eigenvectors play a crucial role in many branches of mathematics and science. When the eigenvector v is multiplied by A, the eigenvalue indicates how much it is scaled.

The eigenvalue and eigenvector states that, let v be a non-zero eigenvector of A corresponding to the eigenvalue λ.

Then, we have:

Av = λv

Taking transpose on both sides we have:

\(v^T A^T = \lambda v^T\)

The above equations thus relates transpose of vector and transpose of A to λ.

Now, consider a matrix:

\(\left[\begin{array}{cc}1&2\\3&4\\\end{array}\right]\)

Now, the eigen values of this matrix are λ1 = -0.37 and λ2 = 5.37.

The eigenvectors are:

\(v1 = [-0.8246, 0.5658]^T\\v2 = [-0.4159, -0.9094]^T\)

Now, for transpose of A:

\(A^T=\left[\begin{array}{cc}1&3\\2&4\\\end{array}\right]\)

The eigen vectors are:

\(u1 = [-0.7071, -0.7071]^T\\u2 = [0.8944, -0.4472]^T\)

Hence, we see that, if λ is an eigenvalue of A, then λ is an eigenvalue of \(A^T\). Show with an example that the eigenvectors of A and \(A^T\) are not the same.

The value of side length x (DF) in the triangle is 4.

What is the value of x?

The figures in the image is that of two similar triangle.

Triangle ABC is similar to triangle DEF.

From the diagram:

Leg 1 of the smaller triangle DE = 5

Leg 2 of the smaller triangle DF = x

Leg 1 of the larger triangle AB = 30

Leg 2 of the larger triangle AC = 24

To find the value of x, we take the ratio of the sides of the two triangle since they similar:

Hence:

Leg DE : Leg DF = Leg AB : Leg AC

Plug in the values:

5 : x = 30 : 24

5/x = 30/24

A. 3f + 6 feet
B. 6f + 3 feet
C. 3f + 18 feet
D. 6f + 18 feet

Answers

The height of the tree after 6 years can be expressed as "3 feet + 6f feet."

The correct answer is A. 3f + 6 feet.

To determine the current height of the tree in terms of "f,"

let's analyze the given information.

We know that the tree was initially 3 feet tall when it was planted 6 years ago.

Since the tree grows every year, we can assume that its growth rate is consistent.

Let's denote the current height of the tree as "h" (in feet).

After 6 years, the tree has grown by a certain amount, which we'll represent as "6f" (6 years multiplied by the growth rate "f").

Therefore, the height of the tree after 6 years can be expressed as "3 feet + 6f feet."

The initial unit is “mL” which has to be cancelled out (by the correct unit multiplier) so that the final answer is expressed in the desired units of “L”. Therefore the unit multiplier shown on the left will be used:

The set of ordered pairs that represents a function is (D) {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}.

A set of ordered pairs represents a function if each unique input (x-value) is associated with only one output (y-value).

{(-4, -3), (-2, -1), (-2, 0), (0, -2), (0, 2)}

In this set, both (-2, -1) and (-2, 0) have the same x-value but different y-values. Therefore, this set does not represent a function.

{(-5, -5), (-5, -4), (-5, -3), (-5, -2), (-3,0)}

In this set, all the ordered pairs have the same x-value (-5). Since (-5, -5), (-5, -4), (-5, -3), and (-5, -2) have the same x-value but different y-values, this set does not represent a function.

{(-4, -5), (-4, 0), (-3, -4), (0, -3), (3, -2)}

In this set, (-4, -5) and (-4, 0) have the same x-value but different y-values. Therefore, this set does not represent a function.

{(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}

Given that a+b = 10 and a square - b square = 40 find the value of a-b

Answer:

the value of a - b is 4.

Step-by-step explanation:

We have been given the following two equations:

a + b = 10 ------------(1)

a² - b² = 40 -------(2)

We can factor the left-hand side of equation (2) using the difference of squares identity:

(a + b)(a - b) = 40

Substituting equation (1) into this equation, we get:

10(a - b) = 40

Dividing both sides by 10, we get:

a - b = 4

Therefore, the value of a - b is 4.

Step-by-step explanation:

if I understand this correctly :

a + b = 10

a² - b² = 40

(a² - b²) = (a + b)(a - b) = 40

10(a - b) = 40

(a - b) = 4
