Answer:
13.9 each sec
Step-by-step explanation:
There are 24hrs in one day and 1,440min in a day, and 86,400sec in a day. 1.2m per day, so 1,200,000/86,400= 13.9
The probability that at least two of the missiles hit the arsenal:
P ( x ≥ 2 ) = P ( x = 2 ) + P ( x = 3 )
P ( x = 2 ) = 0.75 · 0.85 · 0.1 + 0.85 · 0.9 · 0.25 + 0.75 · 0.9 · 0.15 =
= 0.06375 + 0.10125 + 0.19125 = 0.35625
P ( x = 3 ) = 0.75 · 0.85 · 0.9 = 0.57375
P ( x ≥ 2 ) = 0.35625 + 0.57375 = 0.93
Answer:
The probability is 0.93 or 93%.
Answer:
96
Step-by-step explanation:
8x(5+7)
Parentheses first
8* (12)
Then multiply
96
3y^2 and -3/4y^2
5x and 2/3x
12x^2
I think it's 6.80 hope it helped
