Consider functions f and g. Which statements are true about the relationship between the functions?

Function g opens in the same direction as function f.
The vertex of function g is 4 units to the right of the vertex of function f.
The vertex of function g is 2 units below the vertex of function f.
The vertex of function g is 4 units to the left of the vertex of function f.
Function g opens in the opposite direction of function f.
The vertex of function g is 2 units above the vertex of function f.

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.

boxplot

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
