The events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

The probability is defined as the chances of happening any event. Mutually exclusive events are those in which the one event is independent of the other event.

The condition for the mutually exclusive event will be:

[tex]P(A|B)=\dfrac{P(A) \ and P(B)}{P(A)}=P(A)[/tex]

We have the data

red,    0.28

black,  0.30

white,  0.22

other   0.20

Here we will check the mutually exclusive event:-

(1)The events red and black

[tex]P(R|B)=\dfrac{P(R\ and\ B)}{P(B)}[/tex]

[tex]P(R|B)=\dfrac{0.28\times 0.30}{0.30}=0.28 =P(R)[/tex]

Hence the event is exclusive.

(2)The events white and other

[tex]P(W|O)=\dfrac{P(W\ and\ O)}{P(O)}=P(W)[/tex]

[tex]P(W|O)=\dfrac{ 0.22\times 0.20}{0.20}=0.22=P(W)[/tex]

Hence the event is exclusive.

(3) The events red and other

[tex]P(R|O)=\dfrac{P(R\ and\ O)}{P(O)}=P(R)[/tex]

[tex]P(R|O)=\dfrac{ 0.28\times 0.20}{0.20}=0.28=P(R)[/tex]

Hence the event is exclusive.

Hence the events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

Answer:

[tex]25C_{12}[/tex]

Step-by-step explanation:

We are given that an expression

[tex]\frac{25!}{(25-12)!12!}[/tex]

We have to find the expression which represents  [tex]\frac{25!}{(25-12)!12!}[/tex].

We know that

[tex]nP_r=\frac{n!}{(n-r)!}[/tex]

[tex]nC_r=\frac{n!}{(n-r)!r!}[/tex]

By using the formula

By comparing we get

n=25,r=12

[tex]\frac{25!}{(25-12)!12!}[/tex]

[tex]=25C_{12}[/tex]

Hence, option a is true.

[tex]25C_{12}[/tex]

I like to work with the slope-intercept form of the line:

x=4y-8 �> y = (1/4)x + 2 (1)

12x+y=11 �> y = -12x + 11 (2)

At the point where they intersect the two y values must be equal, so set eq(1) = eq(2):

(1/4)x + 2 = -12x + 11

( (1/4) + (48/4))x = 9

(49/4)x = 9

Ans: x = 36/49

Check: Plug in x=36/49 to eq(1) and eq(2) to make sure they produce identical y values:

(1) y = (1/4)(36/49) + 2 = (9/49) + (98/49) = 107/49

(2) y = -12(36/49) + 11 = (-432/49) + (539/49) = 107/49 (they match)

By using substitution method,

The x-coordinate of the point where the lines x=4y−8 and 12x+y=11 intersect is  [tex]\frac{36}{49}[/tex].

"The substitution method is one of the algebraic methods to solve linear equations. It involves substituting the value of any one of the variables from one equation to the other equation."

We have the lines

x=4y−8 ..........................(1)

12x+y=11 .........................(2)

By using substitution method

Substitute x = 4y - 8 in equation (2)

⇒ 12(4y-8) + y = 11

⇒ 48y - 96 + y = 11

⇒ 49y = 11 + 96

⇒ y = [tex]\frac{107}{49}[/tex]

Calculating the x - coordinate by substituting y value in equation (1)

x=4y−8

⇒ x = [tex]4(\frac{107}{49} )-8[/tex]

⇒ x = [tex]\frac{428-392}{49}[/tex]

⇒ x = [tex]\frac{36}{49}[/tex]

Hence, the x-coordinate of the point where the lines x=4y−8 and 12x+y=11 intersect is  [tex]\frac{36}{49}[/tex].

Answer:

8units²

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the opposite sides

h is the height

Take a square as 1 unit

a = 1 unit

b = 3 units

height h = 4 units

Substitute

A = 1/2(1+3)*4

A = 1/2 * 4 * 4

A = 16/2

A = 8units²

Hence the area of the trapezoid is 8units²

3m = 105

/3     /3

m = 35

To check the work just insert 35 for m:

105 - 15 = 90

90 = 90

Answer:

12.5%

Step-by-step explanation:

There are two types of spinners here and the outcome of them is independent. That means

P(odd number,C) = P(odd number) * P(C)

There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:

P(odd) = 2/(2+2)= 1/2= 50%

There are four letters and the desired outcome is C. The chance for C will be:

P(C)= 1/4= 25%

Then the chance will be:

P(odd number,C) = P(odd number) * P(C)

P(odd number,C) =50% * 25% = 12.5%

Answer:

answer = -13

Step-by-step explanation:

number = x

x - 8 = -21

x = -21 + 8
