The <span>cubic model that best fits this data is </span><span>y = 0.0000872x^3 - 0.00989x^2 + 0.403x + 1.192</span>
Answer:
E. None of these answers is reasonable.
Step-by-step explanation:
Customary units are inches, feet, yards, and miles.
Since,
1 foot = 0.3048 meters,
⇒ 1 meter = feet,
17.42 meters = feet
Now, 1 feet = 12 inches,
⇒ feet = inches
=
Hence,
17.42 meters =
= 57' 232/127''
That is, None of these answers is reasonable.
Answer:
The first option will take a total of 3.2 hours while the second option will take just 3 hours
This shows that the second option is faster
Step-by-step explanation:
Here, we want to compare two hiking options and see the one which is faster.
At any point in time;
Distance = speed * time
In the first option, he could hike at 3 mph for two hours.
Total distance covered would be 3 * 2 = 6 miles
Distance left = 12 miles - 6 miles = 6 miles
Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours
Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours
For the second option;
Time = distance/speed = 12 miles/4 mph = 3 hours
We can see that the second option is faster
<span>1. take English and niether of the other two?
</span>36-6 that we know take all 3
This leave 30.
Subtract the 6 from those taking history and English. Leaves 10.
Subtract the 10 from those taking English.
This leaves 20.
Subtract the 6 from those taking political science and English. Leaves 8.
Subtract 8 from those taking English.
Leaves 12
<span>
2. take none of the three courses? </span>
<span>
3. take history, but niether of the other two
</span>Do the same with history as we did with English.
32-6 = 26 -10=16-10=6
<span>
4. take political science and history but not english
</span>16-6 (that take all 3) = 10
Hope at least the partial answer helps!
Distance travelled in heavy traffic = 40*1 = 40 miles
in light traffic = 60*2 = 120 miles
In total, he travelled = 40+120 = 160 miles
