Step-by-step explanation:
Given
Required
--- next roll to be yellow
This is calculated as:
So, we have:
Answer:
14%
Step-by-step explanation:
If the selected student is a male, that reduces the population to consider, to 14 (4 + 6 + 2 + 2).
How many male juniors? 2
So, the chance for the random student to be a junior if he's a male, are 2 out of 14.
P = 2/ 14 = 1/ 7 = 14.29%
Rounded to the nearest whole percent: 14%
Velocity against current = 30 miles / 5 hours = 6 mph
velocity with current = 30 miles / 3 hours = 10 mph
"bv" means boat velocity (no current)
bv (against) -current = 6 mph
bv (with) + current = 10 mph
Adding both equations:
2 * bv = 16 mph
boat velocity = 8 mph
Therefore current = 2 mph

The answer is the top right one.
Each of the other answers is saying the same thing, just in different words, that the slope of the equation is 2. The top right is incorrect.
