- Find f (-5).
Given,
- f (x) = 3x² + x
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,
Answer:
2.38%
Step-by-step explanation:
Given that:
The population size involving numbers of treated and untreated seeds N = 10
the number of seeds that are treated which are observed = 5
the number of seeds that sprouted 'n' = 4
Now, use the method of hypergeometric probability, we have the formula:
∴
p(4) = 0.0238
p(4) = 2.38%
