Step-by-step explanation:

The range of the numbers from the data set is 25

From the information, the five number summary of a dataset was found to be 45, 50, 57, 65, 70.

It should be noted that range is the difference between the highest and the lowest number.

Highest number = 70

Lowest number = 45

Range = 70 - 45 = 25

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).

The height of the tree is 186 inches if Shadow of tree is 523 inch shadow of human is 180 inch height of human is 64 inch.

Cross multiplication occurs when the numerator of the first fraction is multiplied by the denominator of the second fraction, and the numerator of the second fraction is multiplied by the denominator of the first fraction.

We have given information that

Shadow of tree = 523 inch

Shadow of human = 180 inch

Height of human = 64 inch

height of tree = x

Lets solve this with cross multiplication

⇒ [tex]\frac{64}{180} = \frac{x}{523}[/tex]

⇒ 180 × x = 64 × 523

⇒ x = (64 × 523)/180

One way to reduce the risk of fraudulent activity is to assign two persons to check the inventory.

Accounting principles lay out the basic guidelines and ideas and create the foundation upon which specific accounting standards are built.

Inventory-related accounting principles and procedures might be applied unethically. For instance, many teachers in my field who are required to gather and check-in inventory do so while keeping the inventory for themselves. 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. Accounting fraud can be committed in a variety of ways, including overstating revenue, failing to record expenses, and misrepresenting assets and liabilities.

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 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.

We need to know about radical form of a number to solve the question. The simplified version of 2[tex]\sqrt{243}[/tex]x is 18[tex]\sqrt{3}[/tex]x.

Radical form of a number is the simplified version of the number where there is no square root or third root or fourth left of the number.If there is a square root of a number present then we have to simplify it and break it down to a square root from where no other natural number root can be found.In this question we have a number 2[tex]\sqrt{243}[/tex]x, we have to simplify [tex]\sqrt{243}[/tex] so we get the radical form of the number and we assume that x>=0. We can write 243 as 9x9x3, so we can see that for the square root of 243 we can write 9[tex]\sqrt{3}[/tex]. So the number 2[tex]\sqrt{243}[/tex]x can be written as 2x9[tex]\sqrt{3}[/tex]x=18[tex]\sqrt{3}[/tex]x.

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

sum of the resultant arithmetic progression will be 148 is 8.

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.
