Answer:

D. 12 units

Step-by-step explanation:

The distance between two points is found by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

   sqrt( (4 -4)^2 + (-5-7)^2)

 sqrt((0^2 + (-12)^2)

 sqrt(0+144)

sqrt(144)

12

Q4.
Levart [38]

Probabilities are used to determine the chances of an event

  • The probability of choosing a black counter is 0.6
  • The probability that both counters are white is 0.16

<h3>(a) Probability of selecting two blacks</h3>

The probability is given as:

P(Black\ n\ Black)=0.36

Apply probability formula

P(Black) \times P(Black)=0.36

Express as squares

P(Black)^2=0.36

Take the square root of both sides

P(Black)=0.6

Hence, the probability of choosing a black counter is 0.6

<h3>(b) Probability of selecting two white counters</h3>

In (a), we have:

P(Black)=0.6

Using the complement rule, we have:

P(White) = 1 - P(Black)

So, we have:

P(White) = 1 -0.6

Evaluate

P(White) = 0.4

The probability that both counters are white is then calculated as:

P(White\ and\ White) = P(White) \times P(White)

So, we have:

P(White\ and\ White) =0.4 \times 0.4

P(White\ and\ White) =0.16

Hence, the probability that both counters are white is 0.16
