If your original biconditional statement is true, would the contrapositive be true

What is Biconditional statement ?

Biconditional statement can be defined as if in both cases they are equal than they are true otherwise false.

Yes,

If your original biconditional statement is true, would the contrapositive be true

Let us suppose,

P ⇔ Q

Suppose P = true and Q = true

So, P ⇔ Q  is true

and ~P = false and ~Q  = false

¬Q ⇔ ¬P is also true
Therefore, If your original biconditional statement is true, would the contrapositive be true

what is unitary method ?

The unit tactic is a method for addressing dilemmas that entails first figuring out the price of a single unit, then increasing that value to figure out the needed value. Simplest terms, the unit method is used to derive a single unit value out of a multiple that is supplied. For example, 40 pens may cost 400 dollars, which is equal to the cost of one pen. This procedure could follow a regular procedure. a single nation. anything has a distinct identity. Its l'hopital and reciprocal are equal in terms of mathematics, algebra, abstract algebra, mathematical analysis, or mathematics of vectors or operators.

The inverse of the function is g(x) = √[(x + 3)/4]

From the question, we have the following parameters that can be used in our computation:

f(x) = 4x^2 - 3

Rewrite the function as

y = 4x^2 - 3

Swap the variables

x = 4y^2 - 3

Make y the subject

So, we have the following representation

y = √[(x + 3)/4]

Rewrite as

g(x) = √[(x + 3)/4]

Answer: x=-3 & x=3/2

Step-by-step explanation:

1. Simplify the expression

- Divide both sides by the same factor

9=2x^2+3x

2x^2 + 3x - 9 = 0

2. Use the quadratic formula

- Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

2x^2 + 3x - 9 = 0

a = 2

b = 3

c = -9

x = √-3±3^2−4⋅2(−9)/2⋅2

3. Simplify, again.

- Evaluate the exponent

- Multiply the numbers

- Add the numbers

- Evaluate the square root

x=−3±9/4

4. Separate the equations

- To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

x=−3+9/4

x=-3-9/4

5. Solve

- Rearrange and isolate the variable to find each solution.

Answer:

Fred spent $3.18 on brownies.

The probability of the winner is 1/8100. And the probability of losing is 8099/8100.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Let A signify the occasion of putting down a $1 straight bet on a specific lottery and winning. Assume that, for this specific lottery, there are 8,100 unique ways that you can choose the four digits (with reiteration permitted) in this lottery, and only one of those four-digit numbers will be the victor.

Then the probability of the winner is given as,

P(A) = 1 / 8,100

The probability of losing is given as,

Q(A) = 1 - P(A)

Q(A) = 1 - 1/8100

Q(A) = 8,099 / 8,100

The probability of the winner is 1/8100. And the probability of losing is 8099/8100.

Step-by-step explanation:

7/3 in four different ways is 7/12

Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.

If 100 apples are to be shared by 20 girls equally. The number of apple each girl will get is 100/20 = 5 apples each.

Similarly to put 7/3 in four different ways we have to divide 7/3 by 4

7/3 ÷ 4 = 7/3 × 1/4

= 7/12

therefore 7/12 of the four places will give 7/3

The result of 2/3 divided by 1/12 is equal to 8.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

To find the result of 2/3 divided by 1/12, we can use the following equation:

= 2/3 ÷ 1/12 = (2/3) × (12/1)
= 8

Since the multiplication of two numbers is equivalent to the division of their reciprocals, we can use the number line to represent the division as multiplication:

2/3 is located between 1/2 and 1 on the number line, and 1/12 is located between 0 and 1/10. Multiplying 2/3 by 12/1 is the same as moving 12 units to the right on the number line, which is equivalent to moving from 2/3 to 8.

So, the result of 2/3 divided by 1/12 is equal to 8.

The value of x in the parallelogram is calculated to be 11

The value of x is solved using the property of a parallelogram which says that the opposite angles are equal

Applying this mathematically gives

7x - 2 = 75

collecting like terms

7x = 75 + 2

7x = 77

Isolating x by dividing through by 7

7x / 7 = 77 / 7

x = 11

C. a quadratic function with a negative value of a

Step-by-step explanation:

It is likely that a quadratic function with a negative value of a would be the best model for this data, as it would represent a parabolic shape that can accommodate a downward trend, followed by an upward trend, in the stock price. The value of "a" determines the direction of the parabola, with a negative value resulting in a downward-facing parabola, which is appropriate for a stock price that starts low and increases over time. This type of function would provide a good fit for the data, especially if there are fluctuations or ups and downs in the stock price over time.

a. Amount earned  $2,322.76.

b. Total money  $2,322.76

c. Total interest earned $225,268.80

a) To calculate the amount you need to deposit each quarter to reach $500,000 in 30 years, you can use the formula:

P = A / (1 + r/n)^(nt)

P = $500,000 / (1 + 0.066/4)^(4 * 30)

P = $2,322.76

b) Total money

 Total money = $2,322.76 * 4 quarters/year * 30 years

Total money = $2,322.76

c) Total interest earned

Total interest earned = $274,731.20 - $500,000

The equation of line is y = -2x + 9 , where the slope is m = -2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the point be represented as P ( 1 , 7 )
