Im pretty sure he earned 495 in interest, because you take 5,500 time .03 (from the three percent) and you get 165- then multiply by three because of the three years (495)
A fraction that means the same as 2/3 is 4/6.
To find this, you can simply multiple both the numerator and denominator (top and bottom) by any number as long as it's the same number for both top and bottom.
In this case, we used 2 as the number, and multipled it to the top and bottom of 2/3, to get 4/6.
I hope this helps!

Answer:
The proportion of the population that is homozygous for the non-wiggling allele is 0.3056.
Step-by-step explanation:
Denote the variables as follows:
<em>q²</em> = number of people who are homozygous for the scalp-wiggling allele.
<em>p²</em> = number of people who are homozygous for the non-wiggling allele.
It is provided that the proportion of the population who are homozygous for the scalp-wiggling allele is, <em>q²</em> = 0.20.
Compute the value of <em>q</em> as follows:

Compute the value of <em>p</em> as follows:

Compute the proportion of the population who are homozygous for the non-wiggling allele as follows:

Thus, the proportion of the population that is homozygous for the non-wiggling allele is 0.3056.
