Answer:
Step-by-step explanation:
radius is half of it so 7 times 2= 14 and then multiply by 3.14.
So 43.96
(Answer:
P(Bl or Yl) = 45%
(Pk on 2nd draw) = 18%
Step-by-step explanation:
There are a total of 20 marbles (3 + 4 + 5 + 8) in the bag. Since each marble is replaced once drawn, there is no change in the total count from one draw to another (unconditional probability).
So
P(Bl or Yl) = (5 + 4)/20 = 9/20 = .45 = 45%
Then
P(Pk on 2nd draw) = P(1st draw) * P(2nd draw)
= 9/20 * 8/20 = 72/400 = 9/50 = .18 = 18%
9 is the GCF of 18 and 36
Answer:
a positive number
Step-by-step explanation:
-(-) = +
for example, -1 * -1 = 1
The answer is 16+17x18 = 322
