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%.
Answer:
<h2>
A. 1 and 1
</h2><h2>
D. 6 and 1/6
</h2><h2>
E -4/7 and -7/4</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Which pairs of numbers represent a number and its reciprocal?
A. 1 and 1
B. 2/3 and -3/2
C. 1/2 and 5
D. 6 and 1/6
E -4/7 and -7/4
Reciprocal of a number is simply 1 divided by such number. For example the reciprocal of a is 1/a where is any number.
Based on the definition, the following pair of numbers represent a number and its reciprocal
1 and 1
The reciprocal of 1 is 1/1 which is equal to 1
6 and 1/6;
Since I can divide 1 by 6 to get 1/6 , this means that 1/6 is the reciprocal of 6. The pair 6 and 1/6 therefore represent a number and its reciprocal.
-4/7 and -7/4
reciprocal of -4/7 will be 1/(-4/7) = 1 * 7/-4 = -7/4. This shows that -7/4 is the reciprocal of -4/7 hence -4/7 and -7/4 represents a number and its reciprocal.
Answer:
2.987
Step-by-step explanation:
The mean is calculated by dividing the sum of the terms by the # of terms.
For this problem, add all of the terms together:
3.245 + 3.678 + 3.3 + 2.499 + 2.9 + 3.206 + 2.081 = 20.909
Now, divide the product by the number of terms there are. There are 7 terms.
20.909 ÷ 7 = 2.987
The ratio of cars to trucks would be 1.5/1.08.
