Astock boy at a grocery store stacked 12 cans of tuna to make a display. the height of the stack of cans is 40.8 centimeters. if the cans of tuna are all the same height, what is the height of each tuna can?

3.4 centimeters.

Step-by-step explanation:

1. You have the following information given in the problem:

- He stacked 12 cans of tuna to make the display.

- The height of the stack of cans is 40.8 centimeters.

2. Therefore, keeping this on mind, to calculate the height of each tuna can you must divide the height of the stack of cans by the total number of cans. Then, you obtain the following result:

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.
