Answer: E. Convenience
Step-by-step explanation:
- A convenience sampling is a method of sampling whose structure is based on accessibility to the researcher .
Given : An internet site asks its members to call in their opinion regarding their web searching habits.
Here the internet site is working according to its accessibility .
Hence, this is a type of convenience sampling .
I assume the heights are 160 ft and 1480 ft.
The two heights are unknown, so we will use variable h to help solve the problem.
The shorter building, building A, has height h.
Since building A is shorter by 160 ft, then building B is taller by 160 ft, so the height of building B is h + 160.
Now we add our two heights to find the total height.
h + h + 160 is the total height.
We can write it as 2h + 160
We are told the total height is 1480 ft, so we let 2h + 160 equal 1480, and we have an equation.
2h + 160 = 1480
Subtract 160 from both sides
2h = 1320
Divide both sides by 2
h = 660
h + 160 = 820
Building A measures 660 ft.
building B measures 820 ft.
1 gal 2 qts 3 pts
1 gal 3 qts 7 pts
1 gal 3 qts 3 pts
---------------------------add
3 gal 8 qts 13 pts
1 pt = 0.5 qts...so 12 pts = 12* 0.5 = 6...so now we have :
3 gal 14 qts 1 pt
1 qt = 0.25 gal..so 12 qts = 12 * 0.25 = 3 gallons...so now we have :
6 gal 2 qts 1 pt <===
The area of the rectangle is 47 1/2
No, because if you divide 23 / 4, you get 5.75. You can't get 0.75th of a kid. So it is not reasonable, because it is a decimal, and not a whole number.
Hope this helped! ☺♥
