The last two methods listed are likely to be biased. 

The third one, sampling 30 boards in a row an hour after production starts, does not take a very large sample.  Additionally, if something in the machinery is defective only later in the day, the data will be misleading.  Similarly, if the machinery is only faulty until it "warms up," the data will be misleading.

The last method, the voluntary survey, is likely to only get responses from people that feel very strongly one way or the other about their product.  Choosing only 5 responses from this is also not the best choice, as that is an extremely small sample.

Question 1 (1 point)<br> Which equation can be represented by a graph with a vertex at (1,3)?
madam [21]

Answer:

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

f(x) = a {(x - h)}^{2}  + k

Then (h,k) is the vertex, and 'a' is a constant.

For instance

f(x) = 5 {(x - 1)}^{2}  + 3

has vertex at (2,3).

Also, an absolute function in the form

g(x) = a  |x - h|  + k

has vertex at (h,k).

This means

g(x) =   |x - 1|  + 3

also has vertex at (1,3).

I hope this explanation is helpful.

Answer:

The probably genotype of individual #4 if 'Aa' and individual #6 is 'aa'.

Step-by-step explanation:

In a non sex-linked, dominant trait where both parents carry and show the trait and produce children that both have and don't have the trait, they would each have a genotype of 'Aa' which would produce a likelihood of 75% of children that carry the dominant traint and 25% that don't.  Since the child of #1 and #2, #5, does not exhibit the trait, nor does the significant other (#6), then they both must have the 'aa' genotype.  However, since #4 displays the dominant trait received from the parents, it is more likely they would have the 'Aa' genotype as by the punnet square of 'Aa' x 'Aa', 50% of their children would have the 'Aa' phenotype.
