Answer:
volume of fodder=1/3pie R^2h=
l^2=r^2+h^2
l^2=(2.1)^2+(3.6)^2
l^2=4.441+12.96=17.37
l= =4.17m
=4.17m
minimum area of polythene to cover fodder=pieRl=
the volume of fodder is  and minimum area of polythene to cover fodder in the  rainy seasonv47.18m^3
 and minimum area of polythene to cover fodder in the  rainy seasonv47.18m^3
 
        
             
        
        
        
Answer:
The expected revenue of the tour operator is 985.
Step-by-step explanation:
There are two outcomes:
Either less than 21 tourists show up and the operator does not have to pay anything. Or 21 tourists show up and the operator has to repay 100.
Anyways, initially he gets the price of all the tickets sold. That is 21 each at 50, so  .
.
Then, we need to find the probability that all of the 21 tourists show up. In this case, we have to subtract 100 from the revenue.
Each tourist has a 0.02 probability of not showing up. This means that each has a 1-0.02 = 0.98 probability of showing up. So the probability P that all 21 tourists show up is  .
. 
So, the expected revenue of the tour operator is

Rounded up, the expected revenue of the tour operator is 985.
 
        
             
        
        
        
Answer:
75*10=750
Step-by-step explanation:
10 tickets, each 75 dollars, so u multiply 75 by 10 to get 750, just write 75 and rop the 0. $750
 
        
                    
             
        
        
        
Answer:
The intersection point of diagonals is (0.5,-4.5).
Step-by-step explanation:
The end points of first diagonal are p(-3, -2) and i(4, -7).
The end points of second diagonal are a(4, -2) and d(-3, -7).
If a line passing through two points, then the equation of line is

The equation of first diagonal is




 .... (1)
                         .... (1)
The equation of second diagonal is




 .... (2)
                         .... (2)
Add equation (1) and (2),


Put this value in (1).


The intersection point of diagonals is (0.5,-4.5).
