Answer:arc lengths; radius
l guzz.. sry if wrong....
The only value of p for which the equation has exactly 1 real number solution is p=0.
If p<0, there are no real number solutions and if p>0, there are 2 real number solutions.
Hope this helps,

1.A: 86 is equal to (86=) 45 % (which is 0.45) of a number n so 86=0.45n
2. C 4 is npercent of 26, so 4=n*26 where n is a number in percent, with the percent sign!
Var(y)=k(1-p)/p^2
where y is the random variable
k is the successes obtain from y
0<p<1
