Answer:
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Step-by-step explanation:
We assume the following table:
No Hou. smokes >=1 hou. smokes Total
______________________________________________________
Student indicates he Cell 1 Cell 2 Cell 3
or she has asthma
_______________________________________________________
Student indicates he
or she does not have Cell 4 Cell5 Cell 6
asthma
_______________________________________________________
Total Cell 7 Cell8 1000
We are assuming a grand total of 1000 people for this case
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421

Five different problems in one post? That's a turn-off for some potential helpers. Suggest you post only ONE problem at a time.
In regard to the first problem: Your Principal (P) is $8000. The Interest Rate (i) is 19%. The elapsed time is 7 years. Using the formula for continuous compounding:
A = P e^(rt), where "e" is the very common base with value approx. 2.718.
Here, the amount due is A = $8000 * e^(0.19 * 7). Can you evaluate this?
