Answer:
This is an exponential model.
Step-by-step explanation:
The formula for compound interest is
, where a is the principal, r is the interest rate, n is the number of times per year the interest is compounded, and t is the number of years.
Since the number of years will be a variable, we have an equation raised to a power of x; this is an exponential function.
The equation for this would be

Your point on the graph would be ( -8, 0 ).
We shade the right side of the graph because the inequality shows that x is greater than -8.

Answer:
a. 0.6899
b. 0.1642
Step-by-step explanation:
a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:
Hence, the probability of correctly identifying the 6 matches is 0.6899
b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:
#Hence, the probability of correctly identifying the 6 matches is 0.1642
*I have used the sample size of 6(due to conflicting info/question size).
