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: #64, A. #67, A. #68, C
Step-by-step explanation:
#64
0.96/6= 0.16
2.4/16= 0.15
32= 0.18
16 oz is the least
#67
100/20=5
3*5=15
SO, it's 15%.
#68
Divide
$430/43= $10
$594/54= $11
Andrew= $8
So, Darren makes the most.
