Using the uniform distribution, it is found that:
A,B) 0.3 of the time does it take longer than 27 minutes for Josh’s bag to arrive in baggage claim.
C) 20% of the time does Josh’s bag arrive in less than 22 minutes.
--------------------------
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
--------------------------
- In the graph, we have that the distribution is uniform between 20 and 30 minutes, thus
--------------------------
Itens a and b:
- Above 27 minutes, thus:
0.3 of the time does it take longer than 27 minutes for Josh’s bag to arrive in baggage claim.
--------------------------
Item c:
- Less than 22 minutes, thus:
0.2*100 = 20%
20% of the time does Josh’s bag arrive in less than 22 minutes.

The rate to convert yards to meters is
So, if you multiply both sides by 8, you get
To round the answer to the nearest tenth, we need to choose between 7.3 and 7.4. Since the hundreths digit is 1, which is less than 5, 7.3 is nearest to 7.3152 than 7.4, so the correct answer is 7.3
