Does it tell the total number of cards in the bag?
I think the last one, because when you take the parenthesis away it just becomes x - - 3 and you would just make the two negatives a positive
Answer:
0.5 i think
Step-by-step explanation:
I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
Assuming that the person throwing the dart is not aiming for any particular part of the dartboard and that all darts thrown at the board don't miss the board, then we can make use of the area to get the probability
So,
P = A1 / (A1 + A2)
The formula for the area of regular octagon is
A = (1/2) (a) (8) (2a tan 180/8)
A = 8 a² tan 180/8
Where a is the apothem. Substituting, the answer would be
C.
0.27
