Option C:

f(x) = 5x + 7 is the function of the input-output table.

Solution:

Option A: f(x) = 6x + 9

Input x = 1 in the above equation.

f(1) = 6(1) + 9

    = 6 + 9

f(1) = 15

But the output is 12 in the table.

So, it is not the function of the table.

Option B: f(x) = 7x + 5

Input x = 1 in the above equation.

f(1) = 7(1) + 5

f(1) = 12

Input x = 5 in the above equation.

f(5) = 7(5) + 5

f(5) = 40

But the output is 32 in the table.

So, it is not the function of the table.

Option C: f(x) = 5x + 7

Input x = 1 in the above equation.

f(1) = 5(1) + 7

f(1) = 12

Input x = 5 in the above equation.

f(5) = 5(5) + 7

f(5) = 32

Input x = 10 in the above equation.

f(10) = 5(10) + 7

f(10) = 57

Input x = 5 in the above equation.

f(15) = 5(15) + 7

f(15) = 82

All outputs are correct for the given input.

Hence it is the function of the table.

Option D: f(x) = 12x + 1

Input x = 1 in the above equation.

f(1) = 12(1) + 1

f(1) = 12

Input x = 5 in the above equation.

f(5) = 12(5) + 1

f(5) = 61

But the output is 32 in the table.

So, it is not the function of the table.

Hence Option C is the correct answer.

f(x) = 5x + 7 is the function of the input-output table.

The length of time for one individual to be served at a cafeteria is a random variable having an exponential distribution with a
Leya [2.2K]

Answer:

a) 0.25

b) 52.76% probability that a person waits for less than 3 minutes

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

f(x) = \lambda e^{-\lambda x}

In which \lambda = \frac{1}{m} is the decay parameter.

The probability that x is lower or equal to a is given by:

P(X \leq x) = \int\limits^a_0 {f(x)} \, dx

Which has the following solution:

P(X \leq x) = 1 - e^{-\mu x}

The probability of finding a value higher than x is:

P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}

In this question:

m = 4

a. Find the value of λ.

\lambda = \frac{1}{m} = \frac{1}{4} = 0.25

b. What is the probability that a person waits for less than 3 minutes?

P(X \leq 3) = 1 - e^{-0.25*3} = 0.5276

52.76% probability that a person waits for less than 3 minutes

The number of permutations of the problem is

  1. This = 24
  2. Outfit = 360

<u>。。。。。。。。。。。。。。。。。。。。。。。。。。。。。</u>

<u>\:</u>

<h2>Combination</h2>

\:

Combinations are the number of ways to choose members from a certain number, namely from members of a set, combinations can also be interpreted as many ways to make subsets, namely with a certain number of members, namely from members of a set, if a set has n members then the selection of r members, and the combination of n is where r is less than n.

\:

<h3>The Formula : </h3>

\:

<h2>\frac {n!}{k! (n-k)!}</h2>

\:

<h2>Permutation</h2>

\:

Permutations are a way to determine the number of arrangements that occur by paying attention to the order. So in permutations, position/order is very important, namely AB is considered different from BA (AB ≠ BA). Permutation formula

\:

<h3>The Formula :</h3>

\:

\frac {n!}{k!} (With Double Elements)

n! (Without Double Elements)

\:

<h2>Factorial</h2>

\:

The factorial of a natural number is the successive multiplication of a natural number that begins with the number one and arrives at the natural number, the factorial is used in calculating combinations, probabilities, and permutations.

\:

<h3>For example</h3>

\:

  • 》2! = 1 × 2
  • 》3! = 1 x 2 x 3
  • 》4! = 1 x 2 x 3 x 4
  • 》5! = 1 x 2 x 3 x 4 x 5
  • 》6! = 1 × 2 × 3 × 4 × 5 × 6
  • 》7! = 1 × 2 × 3 × 4 × 5 × 6 × 7
  • 》8! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8
  • 》9! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9
  • 》10! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10

\:

The following is an example of a factorial that does not involve mixed arithmetic operations, so if you want to add it up we just need to calculate it like a normal number, a factorial number that only multiplies the difference between a factorial number that is added up by addition, subtraction, multiplication, division, for example see below.

\:

6! x2! - 3! : 4!

\:

The example above is a mixed arithmetic operation that contains multiplication, subtraction, and division. Remember that in mixed arithmetic operations, multiplication/division must be completed before addition/subtraction.

\:

<h3>The Formula : </h3>

\:

n! (Combined Multiplication)

\:

<h2>Place Filling Rules</h2>

\:

The Place Fill Rule is a method or method that can be used to determine the number of ways an object occupies its place. The filling slots rule is a method of calculating how many possible ways there are in an experiment or event. If a first event can be done in m different ways and the second event can be done in a different way and so on until the last event in k.

\:

<h3>The formula</h3>

\:

n1 × n2 × n3 × ... × nr

<h2><u>Question</u></h2>

Find the number of permutations of letters of the word

- this

- outfit

\:

<h2><u>Answer</u></h2>

"Number One"

=》This = Four Letters ( 4! )

P = 4!

P = 1 × 2 × 3 × 4

P = 2 × 3 × 4

P = 6 × 4

P = 24

==========

"Number Two"

=》Outfit = Six Letters ( 6! )

=》Outfit = Two Letters The Same ( "T" ) = 2!

P = \frac {1×2×3×4×5×6}{2×1}

P = \frac {2×3×4×5×6}{2}

P = \frac {6×4×5×6}{2}

P = \frac {24×5×6}{2}

P = \frac {120×6}{2}

P = \frac {720}{2}

P = 360

\:

<h2><u>Conclusion</u></h2>

So, the number of permutations of the problem is

  1. This = 24
  2. Outfit = 360
