Suppose that 30% of a population carries a certain gene. You want to estimate the probability that it will take at least a sampl

e of four to find a person that carries the gene, how could you simulate a person having or not having the gene?
A) 0, 1, 2 could represent a person that carries the gene, and 3, 4, 5, 6, 7, 8, 9 could represent a person that does not carry the gene.

B) 0, 1, 2, 3 could represent a person that carries the gene, and 4, 5, 6, 7, 8, 9 could represent a person that does not carry the gene.

C) 0, 1, 2 could represent a person that does not carry the gene, and 3, 4, 5, 6, 7, 8, 9 could represent a person that carries the gene.

D) 0, 1, 2, 3 could represent a person that does not carry the gene, and 4, 5, 6, 7, 8, 9 could represent a person that carries the gene.

Answer:

A

Step-by-step explanation:

Since only 30% of the population carries the gene, that would mean 70% doesn't carry it. Since you are using 10 digits for this experiment (0-9) this would mean that 0-2 would carry the gene (this equals 30%) and 3-9 would not (70%)

Convert to quarts: 10 pints
Ad libitum [116K]

Answer:

B

Step-by-step explanation:

Pints and Quarts are measures of volume. The relationship between them is rather simple.

We know 2 pints = 1 Quart

The problem gives us the number of pints and we need to find the number of quarts. From the relationship, we see that "pints divided by 2 will give us quarts"

Given >> 10 pints

Hence, number of quarts would be 10/2 = 5

Hence 10 pints = 5 quarts

Answer choice B is right.

Answer:

  (c)  (3, 3)

Step-by-step explanation:

Point E partitions both the x-distance and the y-distance in the ratio 2 : 1. That is, for either the x-coordinates or the y-coordinates, ...

  CE : ED = 2 : 1

Try the answers with the x-coordinates.

  CE : ED = (1 -(-1)) : (5 - 1) = 2 : 4 . . . . incorrect

  CE : ED = (-3 -(-1)) : (5 -(-3)) = -2 : 8 . . . . incorrect

  CE : ED = (3 -(-1)) : (5 -3) = 4 : 2 = 2 : 1 . . . . correct

  CE : ED = (-1 -(-1)) : (5 -(-1)) = 0 : 6 . . . . incorrect

The only viable choice is (3, 3).

_____

<em>Alternate solution</em>

For a partitioning of m : n, the desired point is ...

  E = (n×C +m×D)/(m+n)

For partitioning of 2 : 1, the desired point is ...

  E = (1×(-1, -3) + 2×(5, 6))/(2+1) = (-1+10, -3 +12)/3

  E = (3, 3)
