Answer: D
154 miles.
Step-by-step explanation:
Half way is 440/2 = 220. Subtract the 66 miles already traveled, and they have 154 miles to go.
From the information given:
Random wins 2000 800 400 0
Probabilities 1/10^4 4/10^4 10/10^4 9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92
Answer:
x=12/5
Step-by-step explanation:
4x + 16 - x= 22 + 6
5x+16=28
5x=28-16
5x=12
x=12/5
5 (7 + 23)
(Use distributive property to solve)
1. 5*7 + 5*23
2. 35 + 115
3. 150
