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

Dividing by 4 on both side
Therefore the solution to
is
Answer:
y = -
x + 5
Step-by-step explanation:
The line passes the y axis at 5, so the y intercept is 5. For the slope, the line moves down one and over three, so the slope is negative 1/3.
