Remark.
The easiest way to do this question is to graph it. Start with that.
The red line is y = (1/3)^x
The blue line is y = 5*(1/3)^x
Comment
The red line's y intercept is (0,1)
The blue line's y intercept is (0,5)
Why
If the x value is 0 then (1/3)^0 = 1
y = (1/3)^0 = 1 * 1 = 1 and for the blue graph
y = 5*(1/3)^0 = 5*1 = 5
In other words, in this set of equations, the 5 makes the y intercept 5 times larger than the 1 in front of y = (1/3)^x
If you have choices, could you please list them? I may be giving you the right answer but not in the form required.

if you have already covered slopes, you could also get it that way, in fact is simpler that way.
Answer:
And we can find this probability to find the answer:
And using the normal standar table or excel we got:
Step-by-step explanation:
Let X the random variable that represent the amounts of nocatine of a population, and for this case we know the distribution for X is given by:
Where and
We have the following info from a sample of n =37:
the sample mean
And we want to find the following probability:
And we can use the z score formula given by;
And if we find the z score for the value of 0.872 we got:
And we can find this probability to find the answer:
And using the normal standar table or excel we got:
