Answer:
Let, the c.p be x.
Given,
profit % = 20%
S.P = rs 816
c.p = x
We know,
profit = p% of c.p
= 
* x
= 
now,
C.p = profit + s.p.
x = + 816
x = 
5x = x + 4080
5x-x = 4080
4x = 4080
x = 
x = Rs 1080
Hence, the c.p is Rs. 1080

Answer:
48 +j64 ohms
Step-by-step explanation:
The impedance of a series circuit is the sum ...
R + jXl -jXc
= 48 +j100 -j36
= 48 +j64 . . . . ohms

"j" is the electrical engineer's name for √-1, because "i" is used to represent current.
If I’m correct is rational
I have the answer for the first question, the second one idk how to do. To solve mean add all the numbers and divide by how many there are. 300/5 = 60 so that is the mean. For standard deviation subtract mean from every number in the list and square it. 225, 100,0, 25, and 225. Average these numbers and you will get the standard deviation of 115. Im sorry I cant do the second question but I hope this helped for the first one.
