Answer:
L = 4.103
Step-by-step explanation:
we have length of curve

where 
substituting for f(x), we have 
(since the limit is 2≤ x ≤5)
solving,  
Simplifying this integral, we have
L = 4.10321
 
        
             
        
        
        
Answer:

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
Step-by-step explanation:

Answer:
Option 3 - 
Step-by-step explanation:
Given : Perpendicular to the line  ; containing the point (4,4).
; containing the point (4,4).
To Find : An equation for the line with the given properties ?
Solution : 
We know that, 
When two lines are perpendicular then slope of one equation is negative reciprocal of another equation.
Slope of the equation 
Converting into slope form  ,
,
Where m is the slope.


The slope of the equation is 
The slope of the perpendicular equation is 
The required slope is 

The required equation is 
Substitute point (x,y)=(4,4)
 
 
 
Substitute back in equation,

Therefore, The required equation for the line is 
So, Option 3 is correct.
