Answer:
a
b
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
Generally 2 year is equal to 24 months
Generally the percentage of total production will the company expect to replace is mathematically represented as
Generally 
Generally from the z-table
So
Converting to percentage
=>
Generally the duration that should be the guarantee period if Accrotime does not want to make refunds on more than 6% is mathematically evaluated as
=> 
From the normal distribution table the z-score for 0.06 at the lower tail is
So
=>
Divide 11.25 by (2/3). The answer is 16.875
The Median of the density is -6.
An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
It is clearly visible from the uniform density curve given in the question that the median of the population density is -6.
Because the area to the left and right of the density curve is the same.
Hence, the Median of density is -6.

That is how you graph y=2/5x+2 since 2/5 is the slope and 2 is the y intercept.
A = b√x+c
a/b = √x+c
(a/b)^2 = x + c
(a/b)^2 - x = c
