Ireally need right now. what is an equation of the line that passes through the points (0,7) and (5,4)? put your answer in fully reduced form.

Step-by-step explanation:

apply the slope formula or point slope formula

(0,7) (5,4)=

(4-7)/(5-0)=-3/5

now that we have the slope -3/5 plug that into y=mx+b and solve for b (you can use any of the two points that were given for this part.

7=-3/5(0)+b

7=b

answer

y=-3/5x+7

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.
