Answer:
Step-by-step explanation:
Divide all three terms by 2 to isolate x:
|x + 5/2| > 0.25
Case 1: x + 5/2 > 0.25 (no absolute value symbol needed), or x > -2.25
Case 2: -(x + 5/2) > 0.25. Multiplying both sides by -1 yields
x + 5/2 < -0.25. Subtracting 5/2 from both sides: x < 5.45
The solution set is -2.25 < x < 5.45.
The first one is 5n the second one is the third one the third one is 3,3 the 4th one is 7-q and the last on is the first one
y=2x-3 an x+y=3
subsitution
since y=2x-3, put (2x-3) wherever you see y
put taht in the other equation
x+y=3
x+(2x-3)=3
x+2x-3=3
3x-3=3
add 3 to both sides
3x=6
divide by 3
x=2
subsitute back
y=2x-3
y=2(3)-3
y=6-3
y=3
so the solution set in (x,y) form is (2,3)
Answer: choice A 1/2
Step-by-step explanation:
Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.
so
1/3=2/3*p(B)
p(B)=1/2
