27 = 22 - 2(3 - 1w)....first, we distribute thru the parenthesis
27 = 22 - 6 + 2w...simplify
27 = 16 + 2w...now we subtract 16 from both sides
27 - 16 = 2w
11 = 2w...now we divide both sides by 2
11/2 (or 5 1/2) = w
Answer:
x=2
Step-by-step explanation:
y=-x+5
-1(y)=(x+1)-1 = -y=-x-1
y=-x+5
<u>+ -y=-x-1 </u>
0=-2x-4
0=-2x-4
+4 +4
4=2x
1/2(4)=(2x)1/2
2=x
Answer:
a) 
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that A and B are independent events
P(A∩B) =P(A) P(B)
we will use the conditional probability
