Match the distance with their respective endpoint coordinates
zlopas [31]
The distance between points is calculated through the equation,
             D = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

We calculate for the distances of each of the pairs.

(-3,4) and (3, 4)
     D = sqrt ((4 - 4)² + (3 --3)²) = 6   

(-5,3) and (-5,11)
    D = sqrt ((-5 --5)² +(11 - 3)²) = 8

(-20,-18) and (-22,-21)
   D = sqrt ((-20 --22)² + (-18 --21)²) = 3.6

(2,4) and origin
   D = sqrt ((2 - 0)² + (4 - 0)²) = 4.5

(7,8) and (-2,20)
  D = sqrt ((-2 - 7)² + (8 - 20)²) = 15

Arranging the distances will give us an answer of C, D, A, B, E
The answer is letter C.

A real estate agent is showing homes to a prospective buyer. There are ten homes in the desired price range listed in the area.
Citrus2011 [14]

Answer:

0.48% probability that all four are new

Step-by-step explanation:

The homes are chosen "without replacement", which means that after a home is visited, it is not elegible to be visited again. So we use the hypergeometric distribution to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

Total of 10 homes, so N = 10.

We want 4 new, so x = 4.

In total, there are 4 new, so k = 4.

Sample of four homes, so n = 4.

Then

P(X = 4) = h(4,10,4,4) = \frac{C_{4,4}*C_{6,0}}{C_{10,4}} = 0.0048

0.48% probability that all four are new
