Answer:
i think 88
Step-by-step explanation:
(it's been a while since I've done this so I'm not too sure it's correct)
The formula we need to use is
2πr(angle/360)
we need the radius (r)
To get r we need angle AES
180-80= 100
using the equation from before
88=2πr*(100/360)
raidus: 50.42
Then to get the length CD we need angle DEC
180-80=100
2π*50.42*(100/360)=88
there probably was some kind of shortcut we could've used to figure this out faster but whatever
Answer:
6.73 X 10 to the sixth power.
1.33 X 10 to the fifth power.
9.77 X 10 to the twenty-second power.

Possibly d, but I’m not sure, hope this helps ;)
Answer:
Option C
Step-by-step explanation:
Addition theory of probability is used to determine the probability for union of two or more sets.
P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.
P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)
for 3 sets
This can be extended to any number of sets
So addition theory has nothing to do with independent events both occurring
Option c is the right answer.
