. if the difference between the future amount after 6 periods and the present amount was 600 and the future amount was 2600, what is the simple interest rate per period stated as percentage?
The simple interest rate was found to be 5%
The relation between future amount, present value, rate and annual interest rate is given by the formula,
A= P(1+ rt)
Here, P is present value which is calculated as, P= A(future amount) – (difference between present amount and future amount).
P= 2600-600 = 2000.
Now we calculate interest rate,
A= P(1+rt)
2600 = 2000 (1+6×r)
7r= 2600/2000
r = 0.05.
Thus, the simple interest rate was found to be 0.05 or 5%.
The sum of all the future income that will be produced by an investment is its current value, which is known as the present value of an annuity.
The present value calculation discounts the worth of future payments using the interest rate, desired payment amount, and number of payments to determine the contribution required to achieve and sustain fixed payments for a predetermined amount of time.
The calculation of a loan's interest rate can be done simply by simple interest. Simple interest reward customers who pay their loans on time or early each month by multiplying the daily interest rate by the principal and the number of days that pass between payments.

If people with freckles preferentially mated with other people with freckles, this would be an example of:________
If people with freckles preferentially mated with other people with freckles, this would be an example of Nonrandom mating.
Non-random mating happens when the likelihood that two members of a population will mate differs for every potential genotype combination. Non-random mating can be either assortative or disassortative, depending on whether individuals prefer to mate with similar or dissimilar individuals (e.g., individuals with the same genotype or phenotype). Non-random mating isn't really an evolutionary force since, unlike mutation, selection, drift, and migration, it doesn't truly alter allele frequencies from generation to generation. However, non-random mating does result in deviations from Hardy-Weinberg assumptions since the frequency of genotypes does not meet Hardy-Weinberg predictions. Therefore, non-random mating may indirectly affect evolution in various ways.
As in the question the people with freckles preferentially mate with other people with freckles thus they choose their partners and hence follow non random mating.
