Which of the following expressions is incorrect?
|-12| = 12
-|-12| = -12
-|12| = 12
|12| = 12

-|12| = 12

Step-by-step explanation:

Modulus provides the positive value

So, Option 1)|-12| = 12

So, it is true

Option 2)-|-12| = -12

-|12|=-12

-12=-12

So, it is true

Option 3) -|12| = 12

-|12|≠12

So, it is false

Option 4)|12| = 12

So, it is true

Hence -|12| = 12 is incorrect.

So. Option C is incorrect.

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
