What are the coordinates of the midpoint of the segment whose endpoints are A(−1, −2) and B(6, 12) ? Enter your answer, as decim

Answer:

$(x,y)=\frac{5}{2},5$ is the mid-point of given line segment.

Step-by-step explanation:

We have been given the coordinates of End points

To find the midpoint of the segment we will use mid point formula which is:

$(x,y)=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}$

We have given $x_1=-1,x_2=6,y_1=-2,y_2=12$

Substituting the values in the formula we get:

$(x,y)=\frac{-1+6}{2},\frac{-2+12}{2}$

After simplification we get:

$(x,y)=\frac{5}{2},5$

Probability Trees - See linked image

A good visual method for this is a probability tree.

Each set of branches represents the probabilities of on coin being removed, the second set is out of 9 as the first coin is taken and not replaced.
Multiply along the lines to work out the probability of each of the combinations.
