➷ Calculate the number of hours:
24 x 3 = 72
72/13 = 5.5....
This is 5 whole half lives
You have to half the value 5 times
149/2 = 74.5
74.5/2 = 37.25
37.25/2 = 18.625
18.625/2 = 9.3125
9.3125/2 = 4.65625
The closest value is B. 3.21 so that should be the answer

Answer:
for #1 its the 1st and 4th box
for # 2 it's 13.5 and 20.25
Step-by-step explanation:
1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5
4th box - 10 x 2 = 20 and 25 x 2 = 50
you have to make sure that you do the same thing for both sides of the equation
6 x 2.25 = 13.5
9 x 2.25 = 20.25

Answer:
6.8%
Step-by-step explanation:
the question has no information about class size (no. of student in class)
assume no. of student is infinite
P(3brown out of 6) = 6C3 * P(brown)^3 * P(not brown)^3
= 20 * 0.004913 * 0.695789
= 0.06837
