Answer:

6 segments are required to connect each point to every other point.

Step-by-step explanation:

If four points are placed on a circle.Then as we know the segment is a line that join two points.

Now as we are given four points on the circle.

  • so we will firstly start with the first point; the first point requires 3 segments to connect to the remaining three points.
  • Next second point will just require 2 segments to connect to the two points as it is already connected to the first point.
  • similarly third point requires just one segment to connect to the last point as it is already connected to first and second point as done above.
  • and hence by the above three steps the fourth point is connected to all the points.

Hence, 6 segments are required to connect each point to every other point.

A certain town never has two sunny days in a row. Each day is classified as being either sunny, cloudy (but dry), or rainy. If i
Vikentia [17]

Answer:

In the long run if one day is rainy there is frequency of 2/5 that other two days will also be rainy.

Step-by-step explanation:

A matrix is formed to classify the weather conditions. It is given that if one day is sunny then there is likely chance that the next day will be cloudy, but if one day is rainy then there is 60% chance that next day will be same. To identify the possibility of next two days we create probability matrix;

Probability (P) = \left[\begin{array}{ccc}0&\frac{1}{2} &\frac{1}{2} \\\frac{1}{4} &\frac{1}{2} &\frac{1}{4} \\\frac{1}{4} &\frac{1}{4} &\frac{1}{2} \end{array}\right]

After solving for probability we get a fraction of 2/5

Math homework geometry please help
Ghella [55]

Answer:

A

Step-by-step explanation:

The theorem we use for this is

a(a + b) = c(c + d)

Solve for d.

a(a + b) = c { }^{2}  + cd

a(a + b) -  {c}^{2}

\frac{a(a + b) -  {c}^{2} }{c}

A is the answer
