Answer:
convenience sampling can be very useful, and as the name suggests convenient. This can also lead to some problems though. If the group chosen is a group for a reason related to your research that could affect your findings. Given the example of students in a psych class, if your research is on physical activity levels in the student population, that could be totally fine to use as your sample because physical activity and psychology courses are not directly related. Conversely, if you were going to do research on intended major of first year college students, choosing just one course to pick from may skew your results (an overestimation of those interested in psych as a major)

Answer:
25 quarters, 23 dimes, and 0 nickels.
Explanation:
Let n = number of nickels, q = number of quarters, and d = number of dimes
n + d = q - 2
n + d + q = 48
8.05 = .25q + .1d + .05n
so
(q-2) + q = 48
2q = 50
q = 25
Using that q value:
n + d = q - 2 --> n + d = 25 - 2 --> n + d = 23 --> n = 23 - d
Using that n value and q value:
8.05 = .25(23) + .1d + .05(23 - d)
8.05 = 5.75 + .1d + 1.15 - .05d
2.30 = 1.15 + .05d
1.15 = .05d
23 = d
Using that d value and q value:
n + d + q = 48 --> n + 23 + 25 = 48
n + 48 = 48
n = 0
Therefore there are 25 quarters, 23 dimes, and 0 nickels.
Checking that with:
8.05 = .25q + .1d + .05n
8.05 = .25(23) + .1(23) + .05(0)
8.05 = 5.75 + 2.30 + 0
8.05 = 8.05 ✓
Nadolol works as an antianginal by decreasing the demand for oxygen by the heart, so the abrupt decrease can cause acute myocardial infarction, by increasing the demand for blood quickly.
<h3>What is Nadolol?</h3>
Nadolol is an antihypertensive drug known commercially as Corgard.
This oral medication is indicated for the treatment of high blood pressure and angina pectoris, as it works as an antianginal by decreasing the oxygen demand by the heart.
With this information, we can conclude that nadolol is an antihypertensive drug that cannot be stopped abruptly.

Answer:
Explanation:
In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO2. These six turns require energy input from 12 ATP molecules and 12 NADPH molecules in the reduction step and 6 ATP molecules in the regeneration step.
