Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)

QveST [7]

Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)$

So the midpoint of your segment is

$\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)$

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.

If it rains tomorrow, the probability is 0.6 that John will practice his cello. If it does not rain tomorrow, there is only a

steposvetlana [31]

The final probability is the weighted average of the playing probabilities calculated over the possible weather options:

P(john practices cello; given that it rains) * P(it rains) +

P(john practices cello; given that it does not rain) * P(it does not rain) =

0.6 * 0.7 + 0.4 * 0.3 = 0.54

The probability is 54%
