Each of these questions is substantially the same as the others. The answer is, "it depends" on what you want a random sample of. If you want random people in the country, you will not get that from these protocols.
If you want random people that meet certain criteria (have phones, shop in eyeglasses stores, use specific venues), then these protocols will deliver.

Step-by-step explanation:
(h + k)(x) = h(x) + k(x), thus
h(x) + k(x)
= x² + 1 + x - 2 = x² + x - 1 , then
(h + k)(2) = 2² + 2 - 1 = 4 + 2 - 1 = 5
----------------------------------------------------
(h - k)(x) = h(x) - k(x), thus
h(x) - k(x)
= x² + 1 - (x - 2) = x² + 1 - x + 2 = x² - x + 3, then
(h - k)(3) = 3² - 3 + 3 = 9 - 3 + 3 = 9
-----------------------------------------------------
h(2) = 2² + 1 = 4 + 1 = 5
k(3) = 3 - 2 = 1
Thus
3h(2) + 2k(3)
= 3(5) + 2(1) = 15 + 2 = 17

Answer:
Step-by-step explanation:
<u>We know that:</u>
- 4 packs of Energizer batteries = $2.97
- 10 packs of Duracell batteries = $12.39
<u>Solution:</u>
- 1 pack of Energizer = 2.97/4
- => 1 pack of Energizer = $0.7425
- 10 packs of Duracell batteries = $12.39
- => 1 pack of Duracell batteries = $1.239
Looking at the cost per battery pack, we can say that 4 packs of Energizer is a better buy because its cost per pack is lower than the cost of 10 packs of Duracell batteries.
