Answer:

24

Explanation:

Absolute threshold is a concept that refers to the most minimum level of a sensory stimulus that an individual can sense. Testing this usually require individuals to differentiate the intensity of a stimulus.

A general rule of thumb is that when an individual can sense whether something is stronger 50% of the time, that stimulus level is the person’s absolute threshold.

Thus, in the example of Daniel, we should only pay attention to his 24 candles experiment – since he can recognize the difference in light intensity, 50% of the time, when there are only 24 candles. When he added 11 more candles, making them 35 candles, his ability to recognize the light intensity differences are reduced to 25%.

You believe you must withdraw $12,000 per month during retirement. You plan to be retired for 30 years. Assuming your money will
jek_recluse [69]

Answer:

$2,385,086

Explanation:

To answer this question, we need to use the present value of an ordinary annuity formula:

PV = A ((1-(1+i)^{-n} )/i)

Where:

  • A = Value of the annuity
  • i = interest rate
  • n = number of compounding periods

Because the interest rate is annual, it is convenient to convert it to a monthly rate.

4.5% annual rate = 0.37% monthly rate.

The number of compounding periods will be = 12 months x 30 years

                                                                            = 360 months

Now, we simply plug the amounts into the formula:

X = $12,000((1-(1 + 0.0037)^{-360} )/0.0037)

X = $2,385,086

You will need to have saved $2,385,086 if you plan to retire under the aforementioned circumstances.
