Answer:
Here is another one solved.
P(J/K) = 0.1 means that the probability of event J happening with respect to K is 0.1.However, since J and K are independent events, they are not related to each other. Thus, what ever the probability of event K is, it would not affect the probability of event J happening. So, P(J) would still be equal to 1.
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>
-x² -2x +1=2 <em>(</em><em>S</em><em>implify</em><em>)</em>
x² +2x +2 -1= 0 <em>(</em><em>Bring</em><em> </em><em>all</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>
x² +2x +1= 0
(x +1)²= 0 <em>(</em><em>Factorise</em><em>)</em>
x +1= 0 <em>(</em><em>Square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= -1 <em>(</em><em>-1</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
Answer:
-1
Explanation:
-1 is greater than -2
Pretty much it's just adding one to -2.
