(ASAP PLEASE) so I know the answer is 8 root three but I always come to a dead end up while working it out.

Answer:

The following properties hold for all events A, B.

• P(∅) = 0.

• 0 ≤ P(A) ≤ 1.

• Complement: P(A) = 1 − P(A).

• Probability of a union: P(A ∪ B) = P(A) + P(B) − P(A ∩ B).

For three events A, B, C:

P(A∪B∪C) = P(A)+P(B)+P(C)−P(A∩B)−P(A∩C)−P(B∩C)+P(A∩B∩C).

If A and B are mutually exclusive, then P(A ∪ B) = P(A) + P(B).

• Conditional probability: P(A | B) = P(A ∩ B)

P(B)

.

• Multiplication rule: P(A ∩ B) = P(A | B)P(B) = P(B | A)P(A).

• The Partition Theorem: if B1, B2, . . . , Bm form a partition of Ω, then

P(A) = X

m

i=1

P(A ∩ Bi) = X

m

i=1

P(A | Bi)P(Bi) for any event A.

As a special case, B and B partition Ω, so:

P(A) = P(A ∩ B) + P(A ∩ B)

= P(A | B)P(B) + P(A | B)P(B) for any A, B.

• Bayes’ Theorem: P(B | A) = P(A | B)P(B)

P(A)

.

More generally, if B1, B2, . . . , Bm form a partition of Ω, then

P(Bj | A) = P(A | Bj )P(Bj)

Pm

i=1 P(A | Bi)P(Bi)

for any j.

• Chains of events: for any events A1, A2, . . . , An,

P(A1∩A2∩. . .∩An) = P(A1)P(A2 | A1)P(A3 | A2∩A1). . . P(An | An−1∩. . .∩A

Step-by-step explanation:

Let w represent the width of the playing field in yards. Then the length is 3w-3. The perimeter is given by ...

  P = 2(L+W)

  362 = 2((3w-3) +w)

  181 = 4w -3

  184 = 4w

BD and BC

Step-by-step explanation:

The angle is between this two lines

The rays BD and BC form the angle 65° in the figure.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

When two lines or rays intersect at a single point, an angle is created.

Here, the angle measure is  65°.

An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

And it is created between two rays.

And those rays are BD and BC.

Therefore, the required rays are BD and BC.

x = 22

Given :

C, D, and E  are col-linear, CE = 15.8 centimetres, and DE=  3.5 centimetres.

To Find :

Two possible lengths for CD.

Solution :

Their are two cases :

1)

When D is in between C and E .

.                   .           .

C                  D          E

Here, CD = CE - DE

CD = 15.8 - 3.5 cm

CD = 12.3 cm

2)

When E is in between D and C.

.       .                .

D      E              C

Here, CD = CE + DE

CD = 15.8 + 3.5 cm

CD = 19.3 cm

Hence, this is the required solution.

Answer:

y = [tex]\frac{1}{9}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

y = - 9x + b ← is in slope- intercept form

with slope m = - 9

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-9}[/tex] = [tex]\frac{1}{9}[/tex] , thus

y = [tex]\frac{1}{9}[/tex] x + b ← is the partial equation

To find b substitute (- 18, 3) into the partial equation

3 = 2 + b ⇒ b = 3 - 2 = 1

y = [tex]\frac{1}{9}[/tex] x + 1 ← equation of perpendicular line

Answer:

2.5(x)+6=3.25(x)+3 4=x. Real world problem below

Step-by-step explanation:

Nico is organizing a party. Going skating, admission is 6 dollars, and each person pays 2.5 dollars for a pair of skates. If he has 3 other people in his group, the equation is 2.5(4)+6=24. He is also looking at going to a trampoline park. It is 3 dollars to get in, and 3.25 per person for an hour on the trampolines. This equation can be shown as 3.25(4)+3 which equals 24.

4.052×106=4052000

Explanation:

The number is written in scientific notation, where we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of 10.

In general notation power of 10 is not used and we multiply the number in single digit by the power of 10 to get it in simple standard decimal notation.

Multiplying by a positive power of 10 means moving decimal to right and in case power is negative (this is when the number is less than 1) it meanss moving decimal to left. This is done by the power of 10.

Here we have

4.052×106= 4.0520000×100000= 4052000.

= 4052000

FAILURE OF THE SCHOOL SYSTEM

Answer:

-8

Step-by-step explanation:

Solve the equation:

-2m = 8 - m

-2m + m = 8

-m = 8

m = -8

If you would like to check the answer, plug the value of m back into the equation:

-2 (-8) = 8 - -8

16 = 16

Answer:

m = -8

Step-by-step explanation:

add m to both sides

-2m + m =8 - m + m

simplify

-m = 8

divide sides by -1

-m/-1 = 8/-1

simplify

m = -8

a is called the real part of the complex number and bi is called the imaginary part of the complex number. In the complex number 6 - 4i, for example, the real part is 6 and the imaginary part is -4i.

Answer:

B is the correct answer for this question

Step-by-step explanation:

The number that could represent point Q is to be considered as the option c.  2 1/2.

Since

p = -4

q could be 6.5 units to the right or to the left of point p.

So, to the right it should be like

=p + q

= -4 +  6.5

= 2.5

Hence, The number that could represent point Q is to be considered as the option c.  2 1/2.
