<h2>Question:- Area of the given diagram</h2>
<h2>Answer :- </h2>
Divide the diagram as shown in attachment.
Now first calculate the area of the rectangle having side 1 and 12
So area = length ×breadth
Area = 1× 12 = 12 unit²
Now find the Area of the remaining triangle with sides 12,13,5 units
So

Now put the value as -> base= 5 and height= 12

Now add both areas for your answer

Answer:


Step-by-step explanation:
Given


Solving (a): The mean
This is calculated as:

So, we have:



Solving (b): The standard deviation
This is calculated as:

So, we have:

Step-by-step explanation:
1/4 = 3/12, and 5/4 = 15/12, so it looks like there's a common difference between terms of 4/12 = 1/3. The the
-th term in the sequence is given recursively by

By substitution, we get


and doing this again and again until we stop with an expression containing
, we find that


Then the 12th term in the sequence is
