Based on the demand curves and the movement of the demand curve, the equilibrium price before the demand shift is b and the equilibrium quantity before the demand shift was e.

The equilibrium price refers to the price at the point where the supply and demand curves meet on the graph.

Before the shift in demand, the equilibrium price was at Price b which was the intersection between demand curve d1 and the Supply curve.

The equilibrium quantity was the quantity at this equilibrium price and this was Quantity e.

The probability of getting yellow marbles is 0.23.

Probability is the measure of the likelihood that an event will occur in a Random Experiment.

Experiment: A trial or an operation conducted to produce an outcome is called an experiment.

Sample Space: All the possible outcomes of an experiment together constitute a sample space. For example, the sample space of tossing a coin is head and tail.

Favorable Outcome: An event that has produced the desired result or expected event is called a favorable outcome. For example, when we roll two dice, the possible/favorable outcomes of getting the sum of numbers on the two dice as 4 are (1,3), (2,2), and (3,1).

Trial: A trial denotes doing a random experiment.

Given:

Total marbles= 100

blue marbles = 21

green marbles= 19

red marbles = 37

yellow marbles= 23

So, the probability of randomly selecting a yellow marble

= 23/100

= 0.23

Hence, the probability of randomly selecting a yellow marble is 0.23.

The value of x in the given expression 8 = x over 2.5 minus 6 is (-1/8)^(2/7)

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

given expression is :

-8 = x^(2.5-6)

Now, solving for x by transferring power of x to -1/8 that will become -8 to the power (2/7) :

-8 = x^(-3.5)

-8 = 1/x^(3.5)

x^(3.5) = -1/8

x^(7/2) = -1/8

x = (-1/8)^(2/7)

Therefore, the value of x in the given expression is (-1/8)^(2/7)

Applying the inscribed angle theorem, we have:

1. Measure of inscribed angle EDF = 53°

2. m<DCB = 92°

3. m<VWS = 37°

In a circle, the measure of an inscribed angle is equal to half of the measure of the measure of the intercepted arc, based on the inscribed angle theorem. In order words, the measure of the intercepted arc in a circle, is always twice the measure of the inscribed angle in the circle.

1. Measure of intercepted arc EF = 106° [given]

Measure of inscribed angle EDF = 1/2(measure of arc EF) [inscribed angle theorem]

Substitute

Measure of inscribed angle EDF = 1/2(106)

Measure of inscribed angle EDF = 53°

2. m<DCB + m<DQB = 180° [opposite angles of a cyclic quadrilateral add up to 180 degrees]

Substitute

m<DCB + 88 = 180

m<DCB + 88 - 88 = 180 - 88

m<DCB = 92°

3. m<VWS = 1/2(measure of arc VS) [inscribed angle theorem]

m<VWS = 1/2(74)

The value of f-¹(x) for the function f(x) = (x + 2)/x is y = 2/(x-1).

The inverse of a function f is denoted by f-¹ and it exists only when f is both one-one and onto function. An inverse function in mathematics is function which "reverses" the another function.

For example, If function f which is applied to input a gives result b and then applying inverse of the function g to b, it gives result a and vice versa.

It can be written as:

f(a) = b if and only if g(b) = a or, f⁻¹ (b) = a

In order to calculate the inverse of function f(x) = (x + 2)/x just simply swap the x and y, and solve the resulting equation for the x.

So, we have f(x) = (x + 2)/x, swap the variable x by y, we get

f(x) = (y + 2)/y ............(1)

Now, solving the above equation x = y+2/y for y.

⇒y = 2/(x-1)

∴ The value of f-¹(x) for the function f(x) = (x + 2)/x is y = 2/(x-1).

supplementary angles are two angles that are together 180°.

they don't have to be adjacent, but the fact that the 2 angles can be placed "randomly" in a scenario is rarely used, except maybe for intersection angles of a line with parallel lines.

a linear pair are 2 angles that are truly adjacent (neighbors, touching each other) that are together 180°.

so, our original statement is

if 2 angles are supplementary, then the angles are a linear pair.

that by itself is (as described) not true in all cases. angles can be non-adjacent (and therefore not a linear pair) and still be supplementary.

so the original statement is false.

(a)

the inverse is

if 2 angles are not supplementary, then the angles are not a linear pair.

that is true.

as per the definition, linear pair angles are a true subset of supplementary angles (every linear pair is a pair of supplementary angles, but not every pair of supplementary angles is a linear pair).

so, if they are not a member of the set of supplementary angles, they cannot be a member of a subset either.

(b)

the converse is

if 2 angles are a linear pair, then the angles are supplementary.

that is true.

because linear pair angles are a true subset of supplementary angles. if something is a member of a subset, it is also a member of any superset.

(c)

the contrapositive is

if 2 angles are not a linear pair, then the angles are not supplementary.

that is false.

as described, linear angles are a true subset of supplementary angles. so, an element can be outside a subset but still inside a superset.

like in the original example, 2 angles across intersected parallel lines can be supplementary, but they are not a linear pair.

The measure of side n is √(m^2 - 64).

According to the given question.

We have a right angle triangle.

Here, we have to find the measure n.

Since, the given triangle is divided into two right angle triangles.

Now in the right angled triangle with the side measure m, n and 8.

By the Pythagoras theorem we can say that

m^2 = 8^2 + n^2

⇒ m^2 = 64 + n^2

⇒ m^2 -64 = n^2 ...(i)

The Arithmetic means will be inserted between 1 and 36 such that the

The distinction between the 2 arithmetic orders is a constant value in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.

We'd arrive along all a few key words in AP, which were denoted as:

The AP can also be defined in terms of common distinctions, as illustrated below.

Now, for the stated question;

Assume the first term is'a₁' = 1.

The last term of the series that is nth term is 'a₃₆'.

The sum of all digits between 1 and 36 is given as 148.

Thus, Sn = 148

Substitute the value in the sum formula.

Sn = (n/2)×(a₁ + a₃₆)

148 = (n/2)×(1 + 36)

148 = (n/2)×(37)

n = (148×2)/37

n = 8.

Thus, the total number of Arithmetic means that can be inserted between 1 and 36 is 8.

Having two persons check off the inventory is one method to lower the risk.

Accounting fraud is the illegal modification of a company's financial statements in an effort to hide earnings or losses or to manipulate the company's appearance of health.
