Answer:
w = ⇒ 21
x = ⇒ 13
y = ⇒ -11
z = ⇒ -16
Step-by-step explanation:
The first one is true your welcome hope thi helps
Answer:
Yes!
Step-by-step explanation:
first you need two points (x,y) (x,y).
is the formula you would follow to get the slope. Say you have (2,4) (3,-7) You would plug it into the formula and get
. This example you can simplify it into -11. hope that kinda helps.
Well, first in total there are 16 marbles. So the change of getting a black is 7/16. Now we have 15 marbles. The chance is 6/15. Now we have 14 marbles. The chance is 9/14. When you multiply 7/16 x 6/15 x 9/14 = 9/80
Hope this works
1. B and Y are 2 events,and Y has already occurred.
2. P(B|Y)=P(B∩Y)/P(Y),
gives the probability of B to occur, once Y has already happened.
3. According to the givens (check the diagram at the bottom, of the described problem),
P(B∩Y)=n(B∩Y)/n(U)=8/26=4/13
P(Y)=n(Y)/n(U)=12/26=6/13
P(B|Y)=P(B∩Y)/P(Y)=(4/13)/(6/13)=4/6=2/3=0.67
