Answer:

Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

Answer:
0
Step-by-step explanation:
37×0=0 just like 123x0=0
What is the solution to the proportion? 3 y − 8 12 = y 5 3 y - 8 12 = y 5
Answer:
there is no solution
Answer:
80
Explanation:
The mean of the distribution of sample means always target the population mean. What this line tells is that whatever the population mean will be, the mean of the distribution of sample means will be same. Since the population mean is 80, the mean of distribution of sample means will also be 80.
However, the standard deviation of the sample distributions is different and is equal to the population standard deviation divided by square root of sample size. So in this case the standard deviation of distribution of sample means will be 6 .
