Answer from: JC16

Cost per month is 29 + 0.12m
C = 29+0.12m

m=50
C = 29 + 0.12*50
C = 29 + 6
C = 35

Answer from: jazprincezz5373

Rate fee=$29
charge per minute=$0.12
C(m)=function that represents the total monthly cost.
m=number of minutes spoken.

The equation would be:
C(m)=0.12m + 29

This is similar to the slope-intercept form of a line;
y=mx +b

m=slope
b=y-intercept

but we have written, C(x) instead of y; 0.12 instead of m, and 29 instead of b.

if m=50;
C(50)=0.12(50)+29=6+29=35

the equation would be: C(m)=0.12m+29; if we talk 50 minutes that month the cost would be $35.

Answer from: Quest

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.
