Answer:
Option B
Step-by-step explanation:
Given that the required reserve ratio is 20 percent.
Since banks are conservative they choose not to loan all their excess reserves
i.e. only 20% of deposits is kept as reserve and 80% lent.
This 80% will again be deposited in a bank and 80% of 80 i.e.64% would be lent. Thus this will form a geometric progression infinitely as
deposits with common ratio 0.8<1
Hence infinite sum =
So deposit multiplier is B) equal to 5
For this case, we must find the inverse of the following function:
We follow the steps below:
We exchange the variables:
We put the variable y on the left side of the equation:
We apply logarithm properties:
So:
Answer:
Option B
Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer = 4800
Decrease in the population of the deer after every 8 years =
Decrease in population is an exponential process, so the expression representing population will be,
Where is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x =
By substituting the values of r and x in the expression,
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by () and
should be replaced by
.
Option D. will be the answer.
The probability that exactly 800 chips are acceptable is less than 0.000001
<h3>How to determine the probability?</h3>The given parameters are:
The binomial probability is represented as:
So, we have:
The data values are large.
So, we use a statistical calculator to evaluate the expression
Using the calculator, we have:
P(300) < 0.000001
Hence, the probability that exactly 800 chips are acceptable is very small i.e. less than 0.000001
