<span>N = N0 e^(-kt)
for half life N/N0 = 1/2 and k = 0.1459
1/2 = e^(-0.1459t)
=> -0.1459 t = ln(0.5)
t = - ln(0.5) /0.1459
= 4.8 days </span>

Answer:
a. 50 students are randomly selected from the school; 11 drive to school
b. 407
Step-by-step explanation:
a. to get an accurate viewing, use random people that share 1 large common denominator (from the same school) that also has to do with the question
b. 11/50 is only between 50 students. make the denominator the same (1850) and multiply the same to the numerator
1850/50 = 37
11/50 x 37 = 407/1850
The answer is C because the x value doesn’t repeat
