A tree diagram can be drawn. Since we are not concerned with any result of a head on the coin, we can ignore the branches with heads. To find the probability of the results along the branches, we multiply them, giving rise to the answer 1/32.

Sample size is the number of subjects that are included in research or survey. The sample space for this action is CC, CA, AC, and AA.

<h3>What is a sample size?</h3>

Sample size can be defined as the number of subjects that are included in research or survey.

As it is given that there are two customers, and each of the customers buys any one of the two tickets, a classic ticket (C), or an autograph event ticket (A).

Now, as each of the customers has two choices, therefore, the sample space for this action can be written as,

CC - When both of the customers buy a classic ticket.

CA - When the first customer buys a classic ticket(C) while the other buys an autograph event ticket (A).

AC - When the first customer buys an autograph event ticket (A) while the other buys a classic ticket(C).

AA - When both of the customers buy an autograph event ticket (A).

Hence, the sample space for this action is CC, CA, AC, and AA.

.divide the problem.
quester [9]

Answer:

x - 2x - 15  \: divided \: by \: x - 3

  1. according to the above x²-2x-15 divided by the number below x-3 first I cancel out the x
  2. x  - 2x - 15 \: divided \: by \:  - 3
  3. the we solve the next x-5 divided by x²-9 then as usual rule out the x
  4. - 5 \: divided \: by \: x - 9
  5. now we only have x-2x-15 divided by-3 divided by-5÷x-9 now our next step is to again single the equations out
  6. x - 2x - 15 \: divided \: by \:  - 3 \: lets \: rue \\s \: rule \: out \:  - 3 \: and \: 15 \: giving \: us \: x - 2x - 5
  7. now the next -5 divided by x-9 here there's nothing to rule out therefore the sign "÷" is changed to "×" cancel out the -5 and therefore we have
  8. x - 2x = x - 9 \: as \: final \: answer

Rewrite the Cartesian equation y=-3 as a polar equation.

Explanation:

Imagine we have a point  

P

with Rectangular (also called Cartesian) coordinates  

(

x

,

y

)

and Polar coordinates  

(

r

,

θ

)

.

The following diagram will help us visualise the situation better:

https://keisan.casio.com/exec/system/1223526375

We can see that a right triangle is formed with sides  

x

,  

y

and  

r

, as well as an angle  

θ

.

We have to find the relation between the Cartesian and Polar coordinates, respectively.

By Pythagora's theorem, we get the result

r

2

=

x

2

+

y

The only properties we can say about  

θ

are its trigonometric functions:

sin

θ

=

y

/

r

⇒

y

=

r

sin

θ

cos

θ

=

x

/

r

⇒

x

=

r

cos

θ

So we have the following relations:

y

Now, we can see that saying  

y

in the Rectangular system is equivalent to say
