The real percentage off of pant in the store was 39.99% in the store, which was less than the stated 70% off sign present on the door of store.

The percentage off will be calculated by the formula -

Percentage off = change in cost/original cost × 100

Change in cost = original cost - new cost

Change in cost = 49.99 - 30.

Performing subtraction on Right Hand Side of the equation

Change in cost = 19.99

Keep the values in formula for calculation of percentage off -

Percentage off = 19.99/49.99 × 100

Performing division on Right Hand Side of the equation

Percentage = 0.3999 × 100

Performing multiplication on Right Hand Side of the equation

Percentage = 39.99%

Thus, there was 39.99% off.

The solution set of the inequality |x+2| ≤ 5 is x ∈ [-7,3].

The word inequality means a mathematical expression in which the sides are not equal to each other.

Basically, an inequality compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.

The modulus function, which is also called the absolute value function gives the magnitude or absolute value of a number irrespective of the number being positive or negative.

Modulus function is denoted as y = |x| or f(x) = |x|, where f: R→ (0,∞) and x ∈ R.

Here, we have an inequality  |x+2| ≤ 5

Solving the modulus , we get

          -5 ≤ x+2 ≤ 5

Subtracting -2 from both sides, we get

      ⇒ -5-2 ≤ x ≤ 5 -2

      ⇒ -7 ≤ x ≤ 3

      ⇒ x ∈ [-7,3]

Therefore, the solution set of the inequality is x ∈ [-7,3].

The profit exceeds the cost as y > 1000 + 15x. So, option 1 is correct.

Gaining anything is known as profit. When the Selling price ( SP ) of the product is more than the cost price ( CP ) of the product, we gain profit. Opposite to the profit is loss i.e. losing anything is called loss. When the Selling price ( SP ) of the product is less than the cost price ( CP ) of the product, we get a loss.

Profit can be calculated by the formula,

Profit   =   Selling Price - Cost price

      P   =   SP - CP

Loss can be calculated by the formula,

Loss   =   Cost price - Selling price

    L    =   CP - SP

The sum is equal to 4.

∴  8 (x+2) = 4

Therefore the required equation is  8 (x+2) = 4 .

An equation is regarded as linear when its highest power continuously equals 1. It is also stated as a one-degree equation. A linear equation with one variable typically has the form Ax + B = 0.

In this case, the variables x is a variable while the variable B is a constant. A linear equation with two variables often has the form Ax + By = C. The variables x and y, their respective coefficients A and B, and the constant C are present in this scenario.

Factorial is a function to calculate number of ways a number of objects can be arranged.

In the given problem, there is a set of 14 jobs in the printer queue, where two of them called job A and job B.

Case 1: job A is the first in the queue order.

In this case, the position of job A is fixed and there are 13 other jobs can be arranged.

Hence, the number of possible ways of case 1 = 13!

Case 2: job B is the last in the queue order.

Similarly, in this case, the position of job B is fixed and there are 13 other jobs can be arranged.

Hence, the number of possible ways of case 2 = 13!

Case 3: job A is the first in the queue order or job B is the last in the queue order.

In this case, 2 positions are fixed, while the other 12 queue positions need to be arranged.

Hence, the number of possible ways of case 3 = 12!

Notice, that case 3 is a subset of case 1 and case 2. Hence,

total possible ways = possible ways of case 1 + possible ways of case 2 - possible ways of case 3

total possible ways = 13! + 13! - 12!

                                = 2 x 13! - 12!

When two sides and sides of one triangle are equal then it can be said that the triangles are congruent.

Here we have to find the case in which it can be proven that two triangles are congruent.

Two triangles are said to be congruent if two angles and the included side of one triangle are equal to two angles and the included side of another side.

One of the simplest ways to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those two triangles must also be congruent. This method is called side-side-side( SSS).

Therefore when two angles and their sides are equal then two triangles are said to be congruent.

The required point estimate of the population mean and the margin of error are 16 and 4.

The point estimate is the value of a statistic that estimate the value of the parameter.

According to given data in the question:

Given, lower point =12, upper point = 20

we know that

Population mean(x) = 12+20/2 = 16

And formula for margin o error,

x + E = upper point  , x - E = lower point

Then, 16 + E = 20

E = 4

The four basic properties of addition are:

Commutative property.

Associative Property.

Distributive Property.

Additive Identity Property.

When we add two or more numbers, their sum is the same regardless of the order of the addends. We can write this property in the form of A + B = B + A.

When we add three or more numbers, the sum is the same regardless of the grouping of the addends. It also means that when we add three different numbers, the result is not affected by the addition pattern followed.

A +( B+C) = (A + B)+C

On adding zero to any number, the sum remains the original number. Adding 0 to a number does not change the value of the number. It is true for natural numbers, whole numbers, fractions, integers, and decimals.

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately
