What needs to be done first is to add up females and males that have passed. 
42 + 14 = 56 
so out of 56 students who passed 42 females passed 42/56 = 3/4 = 0.75 
out of 56 students who passed, 14 males passed which turns into 14/56 = 1/4 = 0.25 
check work; 0.75 + 0.25 = 1.00
NOW WE ARE DOING FAILS.
15 + 5 = 20
so out of 20 students who failed, 15 females failed so it turns into 15/20 = 3/4 = 0.75
out of 20 students who failed, 5 males failed. 5/20 = 1/4 = 0.25 
check work; 0.75 + 0.25 = 1.00
i hope this helped! :) 
        
             
        
        
        
Answer:
1/15
Step-by-step explanation:
This is probably too late but I'll do it anyway.
There are 10 cards in all.
of the 10, 3 are green.
So your chance of drawing the first green is 3/10
Now you have 9 cards in total left. 
Two of them are green
Your chance of drawing a green card again is 2/9
Your total chance of drawing 2 green cards is
2/9 * 3/10 = 6/90
2/9 * 3/10 = 1/15
 
        
             
        
        
        
Answer:
$49.60
Step-by-step explanation:
The equation setup I used for this was as follows: $16 x (112/36)
Using PEMDAS, you'd start with the division part, 112/36. Although, I did this a bit differently, and being a bit further in school, I don't know if you go through this where you're at.
Start by factoring 112 into 4(28). This leaves you with 4(28)/36.
Next, cancel 4 out of 36. Since 4 is the common factor in 28 and 36, you cancel the four out of the equation, leaving you with 28/9. Convert this to its decimal form, 3.1.
Finally, take the 3.1 and multiply that by $16, which comes out to $49.60.
 
        
             
        
        
        
Converges by p series test
top section is almost constant, can never be larger than 3
so, compare degrees of their exponents, in this case it’s at a maximum of 3/1000n^2. the same as saying (3/1000)*summation of p series.
converges absolutely.
