Answer:
The distance between foci is 60 feet
Step-by-step explanation:
we are given
a pond has a major axis of 68 feet
so, 
a minor axis of 32 feet
so, 
now, we know ellipse formula

where
c is the distance between center and focus
so, we can plug it and find c


Distance between foci is



In order to solve this, start by adding 1 to both sides of the equation.
m-1=2
+1 +1
-----------
m=3
The solution to your equation is 3.
You can also check to see if this is true by replacing m with 3.
m-1=2
3-1=2
I think it is 36 because you would have to multiply the numbers.

Answer:
hello,
Step-by-step explanation:
a)
p(fail)=0.05
p(not fail)=1-0.05=0.95
b)
p(3 fails)=0.05³=0,000125
c)
p(1 or more system not fail)=1-0.05³=0.999875
d)
it increase the security.( here 4/100 for 3 systems)
(–23) – 45 – (–98) =–23 – 45 +98=-68+98=30
