The reason why the trails must be in quadrant 2 or 3 is because the coordinates start with a negative number. Quadrant 2= (-,+) and quadrant 3= (-,-)
Answer:
what is the equation?
Step-by-step explanation:
To get the coordinates of C we shall proceed as follows:
AB:BC=1:4
B-A=[(-3--7),(-5--8)]=(4,3)
4(4,3)=(16,12)
thus the coordinates of C will be:
(16-3,-5+12)
=(13,7)
Answer:
Step-by-step explanation:
Thats what i got but you still have to do the other 2 steps i am not sure how, but i hope that helps!
7 + 8 + 5 = 20 total marbles
8 blue
probability of picking a blue marble = 8/20, reduces to 2/5 = 0.40
since she puts the first marble back, the 2nd pick is the same probability as the first one
so the probability of picking 2 blue would be 0.40 x 0.40 = 0.16
