Answer:
C= 10.6
Step-by-step explanation:
AB^2=AC^2+CB^2
C^2=7^2+8^2
C^2= 113
√113=10.630
99
Remember that distance is positive and so the distance between 32 and - 67 is
32 - (- 67) = 32 + 67 = 99

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:
![P(X|A)=1\\P (X|A^{c})=0.005\\P(A)=0.01](https://tex.z-dn.net/?f=P%28X%7CA%29%3D1%5C%5CP%20%28X%7CA%5E%7Bc%7D%29%3D0.005%5C%5CP%28A%29%3D0.01)
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:
![P(A)=P(A|B)P(B)+P(A|B^{c})P(B^{c})](https://tex.z-dn.net/?f=P%28A%29%3DP%28A%7CB%29P%28B%29%2BP%28A%7CB%5E%7Bc%7D%29P%28B%5E%7Bc%7D%29)
Use this law to compute the probability of person having a positive result as follows:
![P(X)=P(X|A)P(A)+P(X|A^{c})P(A^{c})\\=(1\times0.01)+(0.005\times(1-0.01))\\=0.01+0.00495\\=0.01495](https://tex.z-dn.net/?f=P%28X%29%3DP%28X%7CA%29P%28A%29%2BP%28X%7CA%5E%7Bc%7D%29P%28A%5E%7Bc%7D%29%5C%5C%3D%281%5Ctimes0.01%29%2B%280.005%5Ctimes%281-0.01%29%29%5C%5C%3D0.01%2B0.00495%5C%5C%3D0.01495)
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%.
