What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , a monomial that will make the expression as a square of a sum or a difference of trinomial is calculated as

(a-b)² = a² -2ab + b²

where a² = 36

taking square roots on both sides of the equation , we get

a = 6

-2ab = -12x

So , one of the variable is x

So , substituting the value of b = x , we get

( 6 - x )² = 36 - 12x + x²

Therefore , the value of the monomial is x²

Hence , The monomial that will make the expression as a square of a sum or a difference of trinomial is x²

The probabilities for the given problem is calculated as 0.081 and 0.06 respectively.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

Given that,

There are 3 blue marbles, 5 red marbles and 4 green marbles.

Then, the total number of marbles is 12.

The given problem can be solved as follows,

Part A:

The probability of getting 1 blue and 2 green marbles is,

P( 1 blue and 2 green) = (³C₁ × ⁴C₂)/¹²C₃

                                     = ( 3 × 6)/ 220

                                     = 9/110

                                     = 0.081

Part B:

The probability of selecting one blue marble = 3/12 = 1/4

After one blue marble is selected, the remaining number of marbles is 11.

Thus, probability of selecting 3 red marbles is,

⁵C₃/¹¹C₃

= 10/165

= 0.06

Part C:

In the Part A the probability is calculated by taking the ratio of total number of ways of selecting 3 marbles and the number of ways of selecting 1 blue and 2 green marbles.

And, in Part B the number of ways is calculated from the remaining number of marbles after one blue marble is chosen.

Hence, the probabilities for the given parts in the question are 0.081 and 0.06 respectively.

Expressions are mathematical statements without equal signs.

Expressions and Variables

Expressions are simply combinations of different numbers and operators. The reason 4a + 7 qualifies as an expression is because it has 2 values connected by an operator and no equal sign. In this expression, there is multiplication and addition.

Variables are letters in equations or expressions that represent some numerical value. Variables can represent any number, but in this case, we are told a = 1/2.

Solving the Expression

To solve the expression, all we need to do is plug 1/2 into the expression.

Then, multiply,

And add,

So, when a = 1/2, 4a + 7 = 9.

To solve this problem, we need to use the formula for the present value of a lump sum payment: $PV = FV \cdot (1 + r)^{-t}$, where $PV$ is the present value (the lump sum payment that needs to be made), $FV$ is the future value (the amount borrowed), $r$ is the annual interest rate, and $t$ is the number of years the money is borrowed for.In this case, we are given that $FV = 12,000$, $r = 8%$, and $t = 5$ years. Plugging these values into the formula, we get $PV = 12,000 \cdot (1 + 0.08)^{-5} = 12,000 \cdot 0.5987 = 7,184.40$.Therefore, the lump sum payment that needs to be made is $PV = \boxed{7184.40}$. The answer is $\boxed{\text{(a)}\ $16,800.00}$ is incorrect.

The conclusion about the triangle is that the two triangles are congruent i.e they are equal

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.

In the figure, triangle ∆GHJ and ∆ GKM are the two triangles formed.

To prove that triangle GHJ = GKM

angle KGM= angle JGH ( opposite angles)

angle K = angle H (alternating angles)

Therefore angle H = angle J

since the three angles of each triangles are equal, we can say the triangles are congruent.

speed of plane's ground = 155.769 Km/h

Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion. In other words, speed is a scalar value, but velocity is a vector.

Units of speed = meter per second

The standard deviation of the scores is  6.48

For given set of scores,  88, 94, 80, 79, 74, and 83

Here, the number of observations = 6

The mean of the scores would be,

μ = Σx/n

μ = (88 + 94 + 80 + 79 + 74 + 83)/6

μ = 498/6

μ = 83

Using the formula of standard deviation,

σ = √((Xi−μ)^2)/n

σ = √[(88 - 83)² + (94 - 83)² + (80 - 83)² + (79 - 83)² + (74 - 83)² + (83 - 83)²]/6

Notice that each day we have the change of that particular day, then we just need to add all of these changes and we will get the total change.

Where the negative numbers mean that the gasoline was used, and the positive numbers represent a charge in the gasoline (so it increases).

C = -1.05 - 1.20 - 0.85 + 10.50 - 2.15 = 5.25

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

A triangle can be named base on it's angles or sides. They include equilateral triangle, scalene triangle, Isosceles triangle, Right triangle, Acute triangle etc

Therefore, let's solve the angle C of the triangle as follows;

m∠C = 2x

x + 2x + 3x = 180

6x = 180

divide both sides by 6

x = 180 / 6
