The probability of a negative result for a batch will be "0.3487".
Given values are:
Positivity rate,
- p = 10% or, 0.1
Batch size,
- n = 10
Now,
The probability of negative result will be:
→
By substituting the values, we get
→
→
→
Thus the answer above is right.

Answer:
combined variation
Step-by-step explanation:
we have
we know that
a)<u> in the interval </u>----> (0,∞)
If the value of x increase the value of y increase
so
Is a direct variation
b) <u>in the interval -</u>---> (-∞,0)
If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
