From the Venn diagram, we can gather that there are 35 total objects (6 in both A and B; 15 in A but not B; 10 in B but not A; and 4 in neither A nor B), and we have the probabilities
(this is the answer)
By definition of conditional probability,
Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n

Answer:
26 feet
Step-by-step explanation:
w: width
w+4 : length
w(w+4) = 572
w² + 4w - 572 = 0
w² + 26w - 22w - 572 = 0
w(w+26) - 22(w+26) = 0
(w-22)(w+26) = 0
w = 22, -26
width = 22 feet
length = w+4 = 22+4 = 26 feet
-3^-3=1/(-3^3)=-1/27 maybe a typo, because you don't have this as an option
could have been -3^-2=1/(-3^2)=1/9
-3^-1=1/(-3^1)=-1/3
-3^0=1
-3^1=-3
-3^2=9
