Answer:
10 meters
Step-by-step explanation:
Let at 100 degrees Celsius, the aluminum bar is x m long.
We have been given that aluminum bar is 2 m long at a temperature of 20 degrees Celsius.
Thus, we have the equation
Solve the equation for x
Thus, at 100 degree Celsius, the aluminium bar is 10 meters long.

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 )
