Answer:
180
Step-by-step explanation:
1. Write a proportion.
=
2. Cross multiply.
6x60=360
360/2=180
x=180
OR
1. Write a proportion.
=
If you look at the bottom, since 2 times 30 is 60, 6 times 30 is 180, making the fractions equal.
As rolling a one on a fair die has a probability of 1/6, on average it is likely that a one will be rolled around once every six rolls, therefore the game’s expected value is 0 because in six rolls one roll will yield 50 and the other five rolls -10 each granting a net total of 0.
So you're trying to figure out the number of miles in a day, so you could do:
<u>total miles</u> = <u>miles</u>
total time day
<u>932.4 miles</u> = 310.8 miles per day
3 days
Subtract 4 from 8, you get 4, then divide -2 from 4 and get 1, x=1
