Answer:
Mean = 1.82
Variance = 1.365
Step-by-step explanation:
We define X as the random variable that counts the number of the carp fishes that has been caught. Also we assume that all the fishes are equally likely to be caught. In that case we have that X as hypergeometric distribution.
The of the Hypergeometric Distribution and Its variance is given below.
Mean of the distribution = 
Variance = 
N= 110
k = 20
n = 10
Upon calculation we get
Mean = 
= 1.82
Variance = 
= 2*90*100/11*11*109 = 1.365
Therefore the mean is 1.82 and variance is 1.365
Option C
<u>Answer:
</u>
The current flowing through the circuit is 5 A
<u>Solution:
</u>
Given that resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V.
We have to find the current flowing through the circuit.
By Ohms law, the relation between the resistance, voltage and current in the circuit is given as,
---- eqn 1
where, V = voltage in the circuit
I = current flowing through the circuit
R = resistance of the electric circuit
From question given that, R = 12 ohms; V = 60 V
By using eqn 1, the current flowing through the circuit is given as
Hence the current flowing through the circuit is 5A.

Answer:
Step-by-step explanation:
The number inside the square root symbol is the number you have to get when you multiply a certain number twice.
So 
:
What multiplied by itself is 121?
Backwards equation:
Do not do the backwards method all the times, it does not work for all numbers.
