Do -(-10) and -|-10| have the same value? *

1 point
1.Yes, -(-10) is the opposite of -10, or 10. Absolute value makes everything positive, so - |-10| always is 10.

2.Yes, both symbols mean absolute value and absolute value makes everything positive.

3.No, -(-10) equals -10 but - |-10| has a value of 10.

4.No, -(-10) has a value of 10 but - | -10| has a value of -10.

Anwer:

No

Step-by-step explanation:

|-10|=10

-|-10|=-10

(-10)=-10

since 1- times 1- = 1

-(-10)=10

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
