Step-by-step explanation:
<em>Step 1: Define the problem</em>
Given:
Lorrie biked
miles in time
hours.
Lorrie traveled at speed
which is greater than
(mile/hour).
Task:
Lorrie wants to determine the distance she may have traveled.
Key point:
The relation among the distance biked
, time
, and the speed
is represented:
x
<em>Step 2: Substitute given data into the main relation</em>
with:
and
=>
x ![t](https://tex.z-dn.net/?f=t)
=>
>
x ![2](https://tex.z-dn.net/?f=2)
Simplify:
![d > 16](https://tex.z-dn.net/?f=d%20%3E%2016)
<em>Step 3: Verify Lorrie's inequality</em>
Lorrie uses the inequality
to conclude that she traveled a distance
at most
miles, or
.
Considering the correct answer is at step 2, in which,
.
=> Lorrie's conclusion is incorrect.
Hope this helps!

Answer:
26 2/3
Step-by-step explanation:
Answer:
You need the combinations formula:
Combinations = n! / (r! * (n-r)!)
where n = total # of choices (8) and r = # of choices (4)
Combinations = 8 * 7 * 6 * 5 * 4! / (4! * 4 * 3 * 2 * 1)
Combinations = 8 * 7 * 6 * 5 / 4 * 3 * 2 * 1
Combinations = 7 * 2 * 5
Combinations = 70
