sample space is the total number of possible outcomes.

when flipping a coin the sample space is {Heads,Tails}.

now for finding the sample space of spinning a wheel with 3 equal parts of say colour Red, Blue, Green:

the sample space is {Red,Blue,Green}

Now the sample space when flipping a coin and spinning a wheel with 3 equal parts will be :

{ (Heads,Red), (Heads,Blue) ,(Heads,green), (Tails, Red), (Tails, Blue), (Tails,Green) }

Suppose that a computer software company has 30
LekaFEV [45]

Answer: \dfrac{30!}{6!(24)!}

Step-by-step explanation:

Given : The total number of programmers in the company = 30

The company wants to select a group of 6 programmers to work on a  particular project.

Since the order of selecting them does not matters , therefore we use combinations.

The number of combinations of r things taken from n things is given by :-

^nC_r=\dfrac{n!}{r!(n-r)!}

here, n= 30 and r= 6

So the number of different ways to form they could select a group of 6 would be ^{30}C_{6}=\dfrac{30!}{6!(30-6)!}

=\dfrac{30!}{6!(24)!}\\\\=\dfrac{30\times29\times28\times27\times26\times25\times24!}{(720)24!}=593775

i.e. Total ways =593775

In terms of factorials , the number of total ways to form they could select a group of 6 is \dfrac{30!}{6!(24)!} .

The length of a rectangle is 2 meters more than its width. The area of the rectangle is 80 square meters. What is the length and
insens350 [35]

Answer:

Step-by-step explanation:

Formula

A = L * W

Givens

W = W

L = W + 2

Solution

Area = L*W

Area = (W+2)*W = 80            Remove the brackets.

Area = W^2 + 2W = 80         Subtract 80 from both sides.

Area = w^2+2W-80=80-80  Combine

Area = w^2 +2W-80 = 0        Factor.

Area = (w+10)(w - 8) = 0

W + 10 = 0 won't work

W = - 10 which isn't possible

W- 8 = 0

W = 8

L = 8 + 2 = 10

The answer looks like A
