Answer: the cyclist must wait for 25 minutes until the hiker catches up.
Step-by-step explanation:
Distance = speed × time
The Cyclist was travelling in the same direction along the same path
as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is
20 × 5/60 = 100/60 miles
For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.
Time = distance/speed
Time required by hiker to catch up with the cyclist is
(100/60)/4 = 100/240 hour
Converting 100/240 hour to minutes, it becomes
100/240 × 60 = 25 minutes

Answer:
0
Step-by-step explanation:
Opposite numbers lie on opposite sides of 0 but are the same distance from 0. For example, the opposite of 3 is -3, and both those numbers are on opposite sides of 0, both 3 units from it.
The opposite of -4 is 4. Those are on opposite sides of 0 and both are 4 units from it.
Zero?
The opposite of 0 is 0 itself! The symbol -0 can be confusing if you read that as "negative zero" and expect it to be on the negative side of the number line. It's better to read that as "the opposite of zero" or, if you want to sound overly smart (but even more correct!), say "the additive inverse of 0".
This all leads up to the idea of absolute value of a number: its distance from 0.
|3| = 3
|-4| = 4
|0| = 0
Answer: 0.0965
Step-by-step explanation:
This would happen if:
First toss: Here we must have any number that is not 6.
the options are 1, 2, 3, 4, 5 so the probablity is p1 = 5/6
The same happens for the second toss, p2 = 5/6
and for the third one: p3 = 5/6
for the fourth toss, person B must roll a 6, so the probability here is p4 = 1/6
Now, the joint probability is equal to the product of the probabilities for each toss, this is:
P = p1*p2*p3*p4 = (5/6)^3*(1/6) = 0.0965
