Answer:
Correct option: (B) 1.495%.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = the test is positive.
<em>A</em> = a person with the dominant allele
The information given are:
According to the law of total probability the probability of an event <em>A, </em>conditional upon the occurrence of another event <em>B</em> is:
Use this law to compute the probability of person having a positive result as follows:
The percentage of positive result is: 0.01495 × 100 = 1.495%.
Thus, the percentage of the population will give a positive test is 1.495%.

Given:
The matrix equation is:
To find:
The value of matrix C.
Solution:
Let 
. Then the given equation can be rewritten as
On substituting the values of the matrices, we get
Therefore, the correct option is C.
Answer:
b because the value are correct
Step-by-step explanation:
The equations give you information as to where to plot points.
For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.
For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.
I hope this helps.
