Answer:
(1,-2)
Step-by-step explanation:
WE can see that the X value below is 1 and the Y value is -2
So the probablity is desired outcomes divided by total possible outcomes
so assume duncan gets an orange on the first try, that would be 4/9
then carlos picks another fruit, also assuming that duncan got an orange so 5/8
then these are dependant on each other so we multiply
4/9 times 5/8=20/72=10/36=5/18
B)
E = mc^2
E = 7 * 5^2
E = 7 * 25
E = 175
c)
b = sqrt (c/d)
b = sqrt (100/4)
b = sqrt (25)
b = 5
