Answer:
Variable-ratio
Explanation:
A variable-ratio reinforcement schedule occurs when a behavior is reinforced based on a random number of displays. Thus, unlike fixed schedules, asking for dating partners do not always elicit a positive reward - which is why it is categorized as variable; the response can be positive or negative. It is also not an interval-based reinforcement schedule, since it is not based on time period. Variable-ratio schedules fit this behavior since asking someone out can get you a positive response once you tried hard enough or with enough people - but when it would happen, you cannot predict.
Answer:
Balance after 30 years = $151,018.50
Explanation:
In order to calculate this, we will calculate the future value on an amount invested, gaining interest over the years of investment, and this is given by:

where:
FV = future value
PV = present value
r = interest rate
t = time in years.
Hence the future value is calculated as follows:
1. For the first 10 years at 7% interest:
7% interest = 7/100 = 0.07


2. For the last 20 years at 9.5%(0.095) interest:
Note that for the remaining 20 years, the present value (PV) used = 24,589.392, as ending balance after the first 10 years


Total Future value earned = $151,018.50
Norovirus is a very contagious virus that causes vomiting and diarrhea. People of all ages can get infected and sick with norovirus. Norovirus spreads easily! People with norovirus illness can shed billions of norovirus particles. And only a few virus particles can make other people sick.
Answer:
e) $37.05
Explanation:
Using the dividend growth model, the value of a stock is the present value of the future dividends receivable discounted at the required rate of return . The required rate of return is given as 12%.
So we discount the year 3 dividend using the dividend growth model formula
P = D (1+g)/r-g
r- rate of return, g = growth rate
Present value of the future dividends:
PV of Year 1 = 1.55(1.015)m × 1.12^(-1)
= 1.4047
PV of Year 2 = 1.55 (1.015)(1.015) × 1.12^(-2)
= 1.27
PV of Year 3 (this will be done in two steps)
Step 1; PV (in yr 2) of year 3 dividend
= (1.55)(1.015)^2×(1.08)/(0.12-0.08)
=43.114
Step 2 : PV (in yr 2) of year 3 dividend
=43.114 × (1.12^(-2))
= 34.37
Best estimate of stock = 1.40 + 1.27 +34.37
= $37.05
Note
To discount the year 3 dividend, we use two steps. The first stp helps get the PV in year 2, and step 3 helps to take it further to the PV in year 0
