Holly rode her bike for 24 miles at 6 miles per hour. she finished her ride at 1: 00 p. m. which explanation correctly tells how to calculate what time holly started her bike ride? a. step 1 divide: 24 ÷ 6. step 2 subtract the quotient from 1: 00 p. m. step 3 write the answer as 9: 00 a. m. b. step 1 divide: 6 ÷ 24. step 2 subtract the quotient from 1: 00 p. m. step 3 write the answer as 12: 45 p. m. c. step 1 divide: 24 ÷ 6. step 2 subtract the quotient from 1: 00 p. m. step 3 write the answer as 9: 00 p. m. d. step 1 divide: 6 ÷ 24. step 2 subtract the quotient from 1: 00 p. m. step 3 write the answer as 12: 45 a. m.

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.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
