Which Table Does NOT Show Direct Variation?

Answers

Answer 1

Answer:

Tables 3. The one in the bottom left corner.

Step-by-step explanation:

Answer 2

The values of table C is not in variation.

What is variation?

Two sorts of quantities typically exist in a mathematical equation when a relationship is established for a certain type of parameter. One is a constant that stays the same regardless of how the other variables in the equation vary, and the other is a variable that changes depending on the circumstances. Variation is the term used to describe the changing of variables.

Given tables,

A direct variation is a straightforward relationship between x and y. To find a direct relationship, either use the formula y = kx or divide y over x (y/x).

Relation for table A

y /x =  -3/1 = -3

y /x = -9/3 = -3

y /x = -18/6 = -3

y /x = -36/12 = -3

relation is in variation.

Relation for  table B

y /x =  3/1 = 3

y /x = 9/3 = 3

y /x = 18/6 = 3

y /x = 36/12 = 3

relation is in variation.

Relation for  table C

y /x =  4/1 = 4

y /x =  6/3 = 2

y /x =  9/6 = 3/2

y /x =  15/12 = 5/3

Equation doesn't have a direct relationship between x and y.

Relation for  table D

y /x = 2/1 =2

y /x = 6/3 = 2

y /x = 12/6 = 2

y /x = 24/12 = 2

relation is in variation.

Hence the table C is not in variation.

Part B: You can also find the standard deviation for the binomial probability distribution of a specific outcome in a binomial experiment. Use the formula to find the standard deviation. You've already identified n and p in Part A. Show your work, and round your answer to two decimal places.

Answers

Answer:

Mean = np + n(n-1)p²

Standard Deviation= √ σ²   = √npq

Step-by-step explanation:

The m.g.f of the binomial probability distribution b(x;n,p) is derived as below.

M₀t = E (e)^tx

        = ∑(e)^tx (nCx) (p)^x q^(n-x)            { x varies from 0 to n}

        = ∑(e)^tx (nCx) (pe^t)^x q^(n-x)

          = (q +pe^t)^n

The expansion of this binomial is purely algebraic and need not to be interpreted in terms of probabilities.

WE get the moments by differentiating M₀(t)  once, twice, etc. with respect to t and putting t=0

Thus

μ₁`  = E(X) = [ d/dt (q +pe^t)^n]    t=0

     = [ npe^t (q +pe^t)^n-1]  t=0  

     = np

And

μ₂`  = E(X²) = [ d²/dt² (q +pe^t)^n]    t=0

      = [ npe^t (q +pe^t)^n-1]    +  [ n(n-1)p²e^²t (q +pe^t)^n-2]    t=0

= np + n(n-1)p²

Variance= μ₂= μ₂`  - μ₁`²

             σ² =E(X²)-  E(X)²

              σ² =np + n(n-1)p²- (np )²

             σ²   =npq

Standard Deviation= √ σ²   = √npq

Step-by-step explanation:

Given the probability distribution :

x : ___ 0 ___ 1 ___ 2

p(x)__0.15 _0.60 __0.25

The expected value is obtained by:

Σ(X * p(x))

(0 * 0.15) + (1 * 0.60) + (2 * 0.25)

0 + 0.60 + 0.50

What is the diagonal?

A polygon is defined as a flat or plane, two-dimensional closed shape bounded with straight sides.

A diagonal is a line segment connecting the opposite vertices (or corners) of a polygon. In other words, a diagonal is a line segment connecting two non-adjacent vertices of a polygon.

Here given that,

In the diagram below of rectangle [tex]RSTU[/tex], diagonals [tex]RT[/tex] and [tex]SU[/tex] intersect

at [tex]O[/tex]. If [tex]RT = 6x + 4[/tex] and [tex]SO = 7x - 6[/tex],

[tex]US=SO(2)\\\\US=7x-6(2)\\\\US=14x-12[/tex]

So,

[tex]6x+4=14x-12\\\\4+12=14x-6x\\\\16=8x\\\\x=\frac{!6}{8}\\\\x=2[/tex]

Hence, option (2) is correct i.e., the length of the [tex]US[/tex] is [tex]2cm[/tex].
