Step-by-step explanation:
Answer: S=360
Step-by-step explanation: Going by the giving question,then we are going to find the surface area of a rectangular prism=lbh
Therefore, let S represent Surface
S=6m×4m×15m
So, our final answer will now be
S=360
Answer:


Step-by-step explanation:
The given parameters can be represented as:

Solving (a): P(x < 3)
This is calculated as:
----- i.e. all probabilities less than 3
So, we have:


Solving (b): Expected number of events
This is calculated as:

So, we have:



Express as decimal

Approximate to the nearest integer

0.25 I think but I’m not sure
Basically the equation for the nth term is
(7n)-3
for the twelfth term, it would be
(7x12)-3
= 81
