If one parents phenotype is Aa and the other parents phenotype is Aa, what is the probability that the offspring will at least carry the receive allele (a)?
To work this problem I would start with setting up a Punnett square (a square broken into 4 parts). Above the box on top you would out an A above the first box and an a above the second box. Then on the far left side you will put an A beside the top box and an a beside the bottom box. Then you will basically match up the alleles from the row and column in each of your first squares. So in your first row first column you would have "AA" in your first row second column you would have "Aa" in your second row first column you would have "Aa" and in your second row second column you would have "aa". So, looking at your square you would see that 75% of the offspring would atleast have one "a" allele.
Katy is hired for a job that receives $600 per month and receives a 15% raise in each following month, in the third month how much will Katy earn?
To start this problem you need to make sure you read it well and clearly understand what it is saying and basically put it into an equation in words.Then, you can take your equation in words and translate it into numbers. So the first month Katy makes 600 dollars. The second month she will make 600 dollars plus an extra 15% of that. The third month Katy will make what she made the second month plus an extra 15% of that. So the first month she will make 600. The second month she will make 600*1.15 which is 690. Then the third month she will make 690*1.15 which is 793.5.
Evaluate: -18 + 4(3x2)^2
This is an order of operations problem. To start this problem you will need to recall the order of operations. I call them PEMDAS to remember them. PEMDAS stands for Parenthesis, Exponents, Multiplication and Division (the order of these are interchangeable as they), Addition and Subtraction (I generally work these two from left to right, but they can also be worked in either order). And then you simply work the problem following PEMDAS. So you would solve what is in the parenthesis first, then take that answer to the power of your exponent (2), then multiply (this one would be by 4), and then add your answer to negative 18.
