Answer:
6.7
Step-by-step explanation:
This is trigonometry. We will have to find the opposite leg and the hypotenuse is given to us as 10. So we will have to use sin. 
Soh in Soh cah toa
                   So  sin(42)=x/10
                         10 times sin(42)=x
                              Evaluate using a calculator=6.69130606 and so on
                                  Rounded to the nearest tenth is 6.7
So the answer is 6.7
 
        
             
        
        
        
There are 10 balls in the Urn Total.
Red: 6
Green: 4
Question One: The probability that five red and two green is selected is likely. (as that is over half for both)
Question Two: Impossible. There is only 6 red balls, and 7 are taken from the urn. Thus it would at most be possible for 6 red and 1 green.
Question Three: At least four is likely, as  there is more red then green in the Urn.

D = m / V 
<span>m = 1.26 g </span>
<span>V = s^3 = 4.1^3 = 68.921 cm^3 </span>
<span>so </span>
<span>D = 12.6 / 68.921 = 0.1828 g/cm^3 </span>
<span>and this corresponds to choice (a)
