1 answer:
Answer:
We are given the below table of information:
Yes No Total
Male 35 45 80
Female 67 28 95
Total 102 73 175
We have to find the probability that a person who does not go to the movies at least twice a week is female.
We know that there are 73 students who does not go to the movies at least twice a week
Also we know that there are 28 female's who does not go to the movies at least twice a week.
Therefore, the probability that a person who does not go to the movies at least twice a week is female is:

Answer:
Rate of Decay = 8%
Step-by-step explanation:
The decay formula is:
Where F is the final value (here, it is given as "Y")
P is the initial value (here, given as 20,000)
r is the rate of decay (what we need to find)
t is the time (given as 2)
Comparing both the equations:
We see that:
1 - r =0.92
We solve for "r":
1 - 0.92 = r
0.08 = r
The rate of decay is 0.08, as a percentage, we need to multiply by 100, so we have:
0.08 * 100 = 8%
Rate of Decay = 8%
