Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that

masha68 [24]

Answer:

This procedure does not result in a binomial distribution because in each trial there are more than two possible outcomes, that is, this problem cannot be simplified as a yes or no question.

Step-by-step explanation:

For the binomial probability distribution being satisfied, two things are necessary:

1) The answer can only be two outcomes, two possibilities, for example, yes/no questions.

2) The probability of a success(an answer) on each trial must be the same. That is, if we are going to survey 100 people if they are Buffalo Bills fans, they will answer yes or no, and each of those 100 people will have the same probability of being a Buffalo Bills fans.

In this problem, we have that:

Surveying 20 college students and recording their favorite TV show.

There is infinite possibilities for each answer. One can answer Narcos, other Monday Night Football, other Sportscentre, and so it goes.

So this procedure does not result in a binomial distribution because in each trial there are more than two possible answers, that is, this problem cannot be simplified as a yes or no question.

If for example, we asked the 20 students if Monday Night Football was their favorite show, then they could answer only yes or no, so it would be a binomial procedure.

Factorise:<br> 14x^2-10x+12

Oksana_A [137]

Answer:

14x^-10x+12+2=-140x+14

Step-by-step explanation:

Very simple. Just add/multiply the like terms, (14x^-10x & 12+2), and then you'll get the answer, but since 140x and 14 are not like terms, the answer stays as 140x+14.

The number of permutations of the problem is

This = 24
Outfit = 360

<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>

<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

This = 24
Outfit = 360

5 less than the quotient of a number and 3 is -7

hram777 [196]

$\frac{x}{3}$ - 5 = -7 .
____________________________________________
This would be one way to write the expresion/equation; in which "x" represents the unknown number.

Now, to solve for "x" ;
____________________________________________
Given:
____________________________________________
$\frac{x}{3}$ - 5 = -7 ;

Add "5" to EACH SIDE of the equation:
_____________________________________________
$\frac{x}{3}$ - 5 + 5 = -7 + 5 ;

to get:

$\frac{x}{3}$ = -2 ;

x = (-2 * 3) ;
_________________________________
x = - 6 .
