Answer:
1 is 27.8%
2 is 41.7%
Step-by-step explanation:
To calculate 1 there is a 10/36 chance (2, 3, 4, 5 out of possible roles of 2 - 12)
To calculate 2 there is a 15/36 chance (2, 3, 5, 7, 11 are prime)
Answer:
20%
Step-by-step explanation:
becuz 2×.2 = .4
subtract .4 from 2 and it's 1.6 and change the .2 to percentage
Let the speed of the boat be x
so going against the current the speed is x-7
going with the current the speed is x+7
let the distance be d
time = distance / speed
time to go against the current = d/(x-7)
time to go with the current = d/(x+7)
time going against the current is 3 times going <span>with the current
</span>
d/(x-7) = 3d/(x+7)
⇒⇒⇒ divide by d
1/(x-7)
= 3/(x+7)
x+7
= 3(x-7)
x+7 = 3x - 21
2x = 28
x = 14
So, the speed of the boat in still water is = 14 mph
Im pretty sure the answer is c) 136
