<em>Hey there!</em>
Well if the length is 18 and 3 inches we need to find the sum of both lengths,
18ft 3in + 18ft 3in = 36ft 6in
Width- 10ft 8in + 10ft 8in = 20ft 16 in -> 21ft 4in
l + w = 57ft 10in
<em>Hope this helps :)</em>
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀
Number of architecture majors = 100
We need to check that whether students at her university had an internship rate that was higher than the national average.
Proportion for her university = 43% = p₁
Here, n = 100
Since n > 30.
so, we can use z-test.
Z-test is generally use to identify whether two means are different when the standard deviation is given.
Hence, it is safe to use the z-test for p.
Therefore, option 'a' is correct.

Answer:
Answer : The bicyclist's average rate of speed in miles per hour is 15 mile/hr.
Step-by-step explanation:
Average rate if speed : It is defined as the ratio total distance to total time.
Formula used :
As per question,
Total distance traveled by bicyclist = 4.5 mile + 7.5 mile = 12 mile
Total time taken by bicyclist = (8:48 A.M - 8:00 A.M) = 48 min = 0.8 hr
conversion used : ( 1 hour = 60 minute)
Now put all the given values in the above formula, we get the bicyclist's average rate of speed in miles per hour.
Therefore, the bicyclist's average rate of speed in miles per hour is 15 mile/hr.
