The second option is true because Elegance Home Architects charges $75 per hour

The fourth option is true, if Nelsons hire design for 5 hours, Elegance Home Architects charges will be cheaper

The fifth option is true, if Nelsons hire design for 25 hours, Rock the House Digital Design charges will be cheaper

Step-by-step explanation:

From the statements

The first option is wrong because it failed to include the initial $500 consultation

The second option is true because Elegance Home Architects charges $75 per hour

The third option is also wrong because the Nelsons are not giving the two companies the job

The fourth option is true from calculation, if the Nelsons are to use 15 hours for the design, then

Elegance Home Architects charges will be = $75 x 15

                                                                         = $1125

Rock the House Digital Design charges will be = $500 + ($50 x 15)

                                                                             =$1250

Therefore, if Nelsons hire design for 5 hours, Elegance Home Architects charges will be cheaper

The fifth Option is also true, if the Nelsons are to use 25 hours for the design, then

Elegance Home Architects charges will be = $75 x 25

                                                                         = $1875

Rock the House Digital Design charges will be = $500 + ($50 x 25)

                                                                             =$1750

Therefore,

From the calculation if Nelsons hire design for 25 hours, Rock the House Digital Design charges will be cheaper

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.

the answer is 11.2 (i know i’m late)
