Answer:
The straight line distance between the school and the candy store is 5.
Step-by-step explanation:
Use Pythagorean theorem
a²+b²=c²
3²+4²=c²
9+16=c²
25=c²
5=c
The answer is 13 because you would plug in 3(3) which is 9 then you multiply (9)(2) which is 18 they you subtract 18-5 which equals 13
Answer:
61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.

Uniform distribution from 0 to 4.8 seconds.
This means that 
61% of the time a person will wait at least how long before the wave crashes in?
This is the 100 - 61 = 39% percentile, which is x for which
. So




61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
Hey!
So here, what we need to do is plug in 100 for n

So 100/101 is our answer
