> don’t have to show the number line< 1) find the distance between -8 and 2 on a number line 2) use a number line to model: 2/5+(-1/5) 3) explain how you find the least common denominators between 3/4 and 5/12 4) if sudeep ran 8 1/4 miles on monday, 10 2/5 on tuesday and only 7 5/8 miles on wednesday. estimate how many miles he ran in those three days to the nearest whole mile. i will mark you as brainliest if u answer the right thing! and don’t answer if u don’t know; -;

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

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.
