A business has a 200 ft wall and places 6 ft letters on the center of an exterior wall to spell SALE. If there is 1ft between each letter, where do they start the letter S?

98.5 ft

Step-by-step explanation:

The 4 letters each spaced 1 ft apart but the last and first letters will be more than 1. The three spaces between letters take 3 ft then the remaining 6-3=3 ft

3/2=1.5 ft at the ends.

200-6=194 ft

So the letters start at 194/2+1.5=97+1.5=98.5 ft

Therefore, the letter S starts at 98.5 ft from one end

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.
