The speed at which they are moving apart = 475 + 525 = 1000 mi/h
Time = distance / speed

Answer:
E) 29.0
Step-by-step explanation:
The value of the sum is obtained from 2 independent experiments: the value of the number of the first box X₁ and the value of the number of the second box X₂.
The expected value of a draw is the average of all its values, so E(X₁) = (1+2+3+4+5+6+7+8+9+10)/10 = 5.5 and E(X₂) = (20+21+22+23+24+25+26+27)/8 = 23.5
Hence, E(X₁+X₂) = E(X₁)+E(X₂) = 5.5+23.5=29
Answer:
5/6
Step-by-step explanation:
The sides numbered 1,2,5 are green and 2,4,6 are even
We cannot count the 2 twice, so there are 5 unique possibilities of getting either a green or an even
There are 6 total possibilities when rolling the die 1,2,3,4,5,6
P (green or even) = green or even/ total
= 5/6
