How to carry out Permutations?

When we pick a particular set of objects in order, it means that we are constructing a permutation. The number of permutations that can be constructed in this way is defined as the product of the number of ways that each object in the given set can be selected.

The formula for permutation is;

P(n,r) = n!/(n-r)!

Thus, different ways can a senior project manager and an associate project manager and a technician be selected for an analytics project if there are eleven data scientists​ available is;

P(11, 3) = 11!/(11 - 3)!

= 990 ways

The quotient of a number x and five

The expression forming by the statement "quotient of a number x and 5" is x/5.

What do we mean by quotient?In this example, the number divided by (15) is known as the dividend, and the number divided by (3 in this instance) is known as the divisor. The quotient is the outcome of the division. The quotient is the result of dividing two numbers by each other. As in the case of 8 ÷ 4 = 2, where the division produced the number 2, the result is the quotient. The dividend is 8 and the divisor is 4. An algebraic expression is referred to as a quotient expression or an algebraic fraction if division comes last in the evaluation process. An algebraic fraction or quotient expression is the expression 7x2+5x.

So, the quotient of a number (x) and 5:

The slope of the line can be calculated using the points (2,2) and (6,10):

[tex]\begin{gathered} m=\frac{10-2}{6-2} \\ =\frac{8}{4} \\ =2 \end{gathered}[/tex]

Since the point (a,8) should belong to the same line, the slope should be the same using the points (a,8) and any other point. Since the slope is 2, use the points (a,8) and (2,2):

[tex]\begin{gathered} 2=\frac{8-2}{a-2} \\ =\frac{6}{a-2} \end{gathered}[/tex]

We got this expression for a:

[tex]2=\frac{6}{a-2}[/tex]

Take the reciprocal of both sides of the equation:

[tex]\frac{1}{2}=\frac{a-2}{6}[/tex]

Multiply both sides by 6:

[tex]\begin{gathered} \frac{6}{2}=a-2 \\ \Rightarrow a-2=3 \end{gathered}[/tex]

Add 2 to both sides of the equation:

OnSaturday, they sold 140 adult tickets and 50 student tickets, and collect $1,230.125a + 65 = 1,200140a + 50s = 1,230This situation is represented by this system of equations:a. What could the equation 265a + 115s = 2,430 mean in this situation?b. The solution to the original system is the pair a = 7 and s = 5. Explain why itmakes sense that this pair of values is also the solution to the equation265a + 115s = 2,430.

Answers

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

students play:

125a + 65s = 1,200 ===> Friday

140a + 50s = 1,230 ===> Saturday

Step 02:

system of equations:

a.

a = adult tickets

s = students tickets

265a + 115s = 2,430

On this day, they sold 265 adults tickets and 115 students tickets, and collect $2,430.

b.

original solution:

a = 7

s = 5

265(7) + 115(5)= 2,430

1855 + 575 = 2430

2430 = 2430

It is verified that the original solution is also valid for this equation.

That is the full solution.

O $30
O $330

Answers

The most appropriate choice for simple interest will be given by-'

Amount of money Josh have at the end of 5 years = $330

Fourth option is correct

What is simple interest?

Simple interest ( SI) is the interest earned on a certain principal at a certain rate over a certain period of time,

If P is the principal, rate is r %, time is t years,

SI = [tex]\frac{p \times r \times t}{100}[/tex]

Adding Principal and simple interest will give the amount

Here,

Principal deposited by Josh= $300

Rate of interest = 2%

Time = 5 years

Simple interest = [tex]\frac{300 \times 2 \times 5}{100}\\[/tex]

                         = $30

Amount of money Josh have at the end of 5 years = $(300 + 30)

                                                                                     = $330

there is a .9987 probability that a randomly selected 27-year old male lives through a year. a life insurance company charges $154 for insuring that the male will live through the year. if the male does not survive the year, the policy pays out $100,000 as a death benefit

Answers

Using probability we know that the expected value of the insurance company is $141.

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.

So, the expected value of the insurance company:

Probability = 0.9987So, 1.0000 - 0.9987 = 0.0013

Now, get the expected value as follows:

E(x) = 0.9987 × 154 + 0.0013(-9987)E(x) = 153.7998 + (-12.9831)E(x) = 153.7998 - 12.9831E(x) = 140.8167

Rounding off: $141

A student worked 52 hr during a week one summer. The student earned $5.70 per hour for the first 40 hr and $8.55 per hour for overtime. How much did the student earn during the week? Enter your answer in the answer box

Answers

Answer:

Total earnings during the week = $330.6

Explanations:

The total number of hours worked during the week = 52 hr

Earnings per hour for the first 40 hours = $5.70

Earnings for the first 40 hours = $5.70 x 40

Earnings for the first 40 hours = $228

The number of hours worked as overtime = 52 - 40 = 12 hours

Earnings per hour for overtime = $8.55

Earnings for overtime = $8.55 x 12

Earnings for overtime = $102.6

Total earnings during the week= Earnings for the first 40 hours + Earnings for overtime

Total earnings during the week = $228 + $102.6

Total earnings durig the week = $330.6

Answer:

A

Step-by-step explanation:

We don't actually need to do any math to figure this out. We can use process of elimination and logical thinking.

we know it's not B because the prices are too close to each other, there is also the fact that 3 books should cost half of 82.50, and 15.75 isn't half of 82.50.

it's not D because 21 books cannot cost 33.75 dollars if 6 books cost 82.50.

it's not c because 12 books should be double the cost of 82.50, which it isn't.

Find all of the zeros of this function and use them to sketch a rough graph.

Answers

The zeroes of the function f(x) = x⁵ - 8x³ - 9x are x = 0, 3, - 3, i, and - i.

Consider the function,

f(x) = x⁵ - 8x³ - 9x

x⁵ - 8x³ - 9x = x( x⁴ - 8x² - 9 )

Factoring: x⁴ - 8x² - 9

The coefficient of x⁴ is 1, the coefficient of -8x² is - 8, and - 9 is the constant term.

x⁴ - 8x² - 9 = x⁴ - 9x² + x² - 9 = x²( x² - 9 ) + 1( x² - 9 )

x⁴ - 8x² - 9 = ( x² - 9 ) ( x² + 1 )

So,

x⁵ - 8x³ - 9x= 0

x( x⁴ - 8x² - 9 ) = 0

x( x² - 9 ) ( x² + 1 ) = 0

x( x - 3 )( x + 3 ) ( x² + 1 ) = 0

Therefore, the zeroes of the function are:

x = 0, x = 3, x = - 3, and

x² + 1 = 0

x² = - 1

x = ± √( - 1 ) = ± i
