! he bellsbells are adding a new room to their house. the room will be a cube with volume 6 comma 8596,859 ft cubed3. they are going to put in hardwood floors, and the contractor charges $1010 per square foot. how much will the hardwood floors cost?

The cost will be $3,610

Step-by-step explanation:

Remember that the volume of a cube is

where

b is the length side of the cube

we have

substitute in the formula and solve for b

The area o the floor will be

substitute

Find out the cost of the hardwood floors

Multiply by $10 the area of the floor

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

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.
