The number of fish caught while fishing for an hour on Lake Poisson follows a Poisson distribution with an average (expected value) of 2.5. You spend 8 hours fishing on this lake. a. What is the probability that you catch exactly 3 fish? b. What is the probability that you catch 2 or more fish? c. What is the variance of the random variable representing the number of fish caught in 8 hours?

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

2y+y=5

add 2y and y

the answer is -1 1/5, also a

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
