Answer:
x=0.823
Step-by-step explanation:
We are given equation as

now, we can find two equations
First equation is

And second equation is

now, we can draw graph
and then we can find intersection points
we get
(0.823,400)
so,
x=0.823
The value of this answer is .B
3 are expected to have the condition.
The expected value is the found by multiplying the probability by the number in the sample:
(1/200)×600
= (1/200)×(600/1)
= (1×600)/(200×1)
= 600/200 = 3
