Answer: f^-1(x) = x/2-7/2
The point estimate would be 2.25%.
Confidence intervals are centered around a point estimate; that is, the point estimate is in the very middle of the confidence interval. We can find the point estimate by averaging both ends of the confidence interval together:
(1.1+3.4)/2 = 2.25.
The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
Answer:
69
Step-by-step explanation:
lol lol lol lol lol lol lol
$17
17+11 = $28
28+11 = $39
39+11 = $50
17 + 11(n-1) $$
n-1 because removes the first class of $17
