Answer:
The percent of the area under the density curve where  is more that 3 is 25 %.
 is more that 3 is 25 %.
Step-by-step explanation:
Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression: 
 (1)
 (1)
Where:
 - Area, in square units.
 - Area, in square units.
 - Base of the triangle, in units.
 - Base of the triangle, in units.
 - Height of the triangle, in units.
 - Height of the triangle, in units. 
The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:


The percent of the area under the density curve where  is more that 3 is 25 %.
 is more that 3 is 25 %.

Answer:
It is 11/15
Step-by-step explanation:
First u add all the numbers to get the total which is 15. Then u add the number of beads that are not pink so it is 7+4 which is 11/15
 
        
                    
             
        
        
        
The product of 3p and q-3 would be put in to equation form like this: 3p(q-3)
To find your answer. You have to distribute the 3p to by individually multiplying it by q and -3
It should now look like this: 

So your answer is: 
 
 
        
        
        
Step-by-step explanation:
a)82km into miles
Sol'n
 Here,
 km=82=82000miles
 m=?
 
Now,
 Miles =km×1000
 =82×1000
 =82000
Therefore,82000m.
