Answer:
c. 0.14
Step-by-step explanation:
Generally, for a given normal distribution, we can estimate the probability of the normal distribution using the equation below:
P (x greater than 
) = pnorm(, mean, sd, lower tail=FALSE)
The following variables are provided in the question:
= 15
n = 30
Therefore:
Mean: E(30*X) = 30(0.47)
Standard deviation: 0.15*
P (y greater than 15) = 1 - pnorm (15, 30*0.47, 0.15*)
P (y greater than 15) = 1 - pnorm (15, 14.1, 0.822) = 0.137
The approximate probability is 0.14
The ratio 6 to 1 is exactly what it sounds 6 is bigger than 1

Answer:
Step-by-step explanation:
Let
s -----> the number of stamps
w ----> the number of weeks
we know that
The linear equation that represent this situation is
----> equation of the line into slope intercept form
where
the slope m is equal to 
the y-intercept b is equal to 
---> (the initial value)
