V=900m³
V=L*w*h
V=20*3*w
V=60*w
60*w=900
w=900/60
w=15m
Answer:
6x-3
Step-by-step explanation:
Answer: Hello your question is incomplete attached below is the missing
n ( 1 + n )
Step-by-step explanation:
P( Bob hits target ) = 1/3
P( Eve hits target ) = 2/3
P( Carol hits target ) = 1
<u>Compute the P that Bob wins in a duel against Eve alone</u>
P(Bob hits the target in first shot ) = n = 1/3
P(Bob hits the target in second shot ) = n^2 = ( 1/3 * 1/3 ) = 1/9
hence the probability of Bob winning( i.e. P( Bob wins Event E1 ) = n + n^2 = n ( 1 + n )
It's A and C, I've taken a test that has this question and it was correct when I answered this, so A and C is your answer.
