-18 doesnt belong to irrational
If you want an answer greater that 7, your fraction needs to be greater than 1.
n can be any number greater than 4
We make the corresponding unit change.
We have then:
V = 13 * (1/3600) * (5280)
V = 19.06666667 feet / s
Then, after 10 seconds, we have by definition:
d = v * t
Where,
v: speed
t: time
Substituting the values:
d = (19.06666667) * (10)
d = 190.6666667 feet
Answer:
V = 19.06666667 feet / s
d = 190.6666667 feet
Interquartile range for group A = 2.5
interquartile range for group B = 1
2.5 - 1 = 1.5 (to find the difference you subtract)
so the answer is: the interquartile range for group A students is 1.5 more than the interquartile range for group B students.
hope this was helpful!
