A person trying to gain access to a bank vault must pass through a series of three security doors. If an attempt to pass through

a door is a failure, then the person will not make any further attempts. Let P denote a successful pass and F denote a failed pass. What is the sample space for this random experiment

Answer:

Sample space is \{F,PF,PPF,PPP\}

Step-by-step explanation:

Number of security doors = 3

Let P denote a successful pass and F denote a failed pass.

Sample space refers to a set of all possible outcomes.

If the first attempt to pass through a door is a failure, then the outcome is F.

If the second attempt to pass through a door is a failure, then the outcome is PF.

If the third attempt to pass through a door is a failure, then the outcome is PPF.

If the fourth attempt to pass through a door is a failure, then the outcome is PPP.

Sample space is \{F,PF,PPF,PPP\}

Can someone help with this math question please

Question 9

For this question, you work out the areas of the different shapes - the two triangles and the large rectangle.
------------------------------------------------------------------------------------------------------------
To get the area of the rectangle, you must use a ruler to measure out the:
 height of the shape and the base of the shape

(try to be as accurate as possible when measuring)

Then to get the area of the rectangle, multiply the Height by the Base. 
-------------------------------------------------------------------------------------------------------------

For the triangles, you measure the out the base and the height .
Then you use the formula for the area of a triangle, which is:

Height x Base x \frac{1}{2}

So, you measure out the base and height of one triangle, then use the formula to work out the area,    then you do the same for the second triangle.
-------------------------------------------------------------------------------------------------------------
Finally, you add up all of the areas:

Total area = area of rectangle + area of first triangle +area of second triangle

then you choose the option that is closest to your answer <span>(remember to be accurate with the ruler!)
</span>-------------------------------------------------------------------------------------------------------------

Question 10<span>

</span>Lets say we wanted to know how much 10 bottles of water cost

To do this, we would multiply the number of water bottles we want (which is 10)  by how much one water bottle costs.<span>

</span>Lets say one water bottle costs £1.  
We would multiply the £2   by 10 (which is the number of water bottles)

So 10 water bottles would cost :   £2 x 10 = <span>£20
</span>
-------------------------------------------------------------------------------------------------------------

Now lets apply this knowledge to the question:

The <u>ANSWER </u>would be:
G) multiplying n by the cost of one bottle

To get the total total cost, we multiply the number of bottles we buy by the cost of one bottle
-------------------------------------------------------------------------------------------------------------

Question 11

For this one, we are told that the company charges $40 for hooking a vehicle.
We are also told that they charge $1.70 for each mile  the vehicle is towed.

Therefore the <u>ANSWER </u>would be;

B) 
c = 40 + 1.70m

$1.70m   means   $1.70   times the number of miles, and we are told that they charge 1.70 for every mile.

Find the volume of a cone that has a radius of 3 inches and a height of 9 inches. Use 3.14 for pi and round your answer to the n
aalyn [17]

Volume of the cone is 100 in³

Step-by-step explanation:

  • Step 1: Volume of a cone = 1/3 πr²h. Find volume of the cone where r = 3 inches and h = 9 inches.

Volume = 1/3 × 3.14 × 3² × 9

             = 84.78 in³ ≈ 100 in³ (rounding off to nearest hundredth)
