Predict what the graph of the following quadratic function will look like. (If you have a graphing calculator, you can use it to verify your prediction.)
y = 0.3x2 - 5
a U-shaped, y-intercept (5,0), symmetrical with respect to the y-axis
b n-shaped, y-intercept (0, -5), symmetrical with respect to the y-axis
C. U-shaped, y-intercept (0, -5), symmetrical with respect to the y-axis
d n-shaped; y-intercept (5,0), symmetrical with respect to the y-axis

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.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
