I believe the correct answer from the choices listed above is option B. Absolute threshold refers to the lowest intensity at which a person can detect stimuli. It is the smallest level of energy required by an external stimulus to be detectable by the human senses. Hope this answers the question.
Solve for n:
2 n + 1 = 5
Subtract 1 from both sides:
2 n + (1 - 1) = 5 - 1
1 - 1 = 0:
2 n = 5 - 1
5 - 1 = 4:
2 n = 4
Divide both sides of 2 n = 4 by 2:
(2 n)/2 = 4/2
2/2 = 1:
n = 4/2
The gcd of 4 and 2 is 2, so 4/2 = (2×2)/(2×1) = 2/2×2 = 2:
Answer: n = 2
Yeah that person explained it perfectly
I think it would be the College Board.
