Answer:
72,000
Step-by-step explanation:
Create equivalent fractions:
23/x = 40/17
Cross multiply and divide:
x = 9.8
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.
Answer:
Step-by-step explanation:
v = 3 (r - 1)
v = 3(- 1 - 3) <----- Here we are substituting R
v = -3 - 9 <---- Here we expanded the bracket
v = -12 <--- This is your answer, because -3 -9 is equal to -12
9000mm
because there is ten mm in one cm
