The midpoint of A (-4, 2) and B(8,5) is
O (2,7/2)
O (-6, 3/2)
O (4,7/2)

(2, )

Step-by-step explanation:

Hi there!

We want to find the midpoint of (-4,2) and (8,5)

To do that, we'll use the midpoint formula, which will find the midpoint using the formula ( ,), where and are points

We have everything we need to find the midpoint, but let's label the values of the points to avoid any confusion

=-4

=2

=8

=5

Now substitute those values into the formula and solve

To find the value of the x-coordinate of the midpoint, use

x=

Add the numbers together on the numerator

x=

Divide

x=2

The value of the x-coordinate is 2

Now find the value of the y coordinate by using

y=

Add the numbers together on the numerator

y=

So the point is (2, )

Hope this helps!

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
