Answer:
181 MP3 players
Step-by-step explanation:
Given data:
Replacement of MP3 that fail within 3 years
expected lifetime of MP3 = 5 years
number of MP3 players purchased = 1000
number of MP3 players replaced in the first year = ?
To determine the number of MP3 replaced in the first year we will employ this formula:
a = ∞
since the given problem is an exponential distribution
1/u = 5 hence u = 0.2
next we will determine the number of MP3's to fail in its first year of purchase
qo = failure
po = success
number of purchase = 1000
attached below is the remaining part of the solution

Answer:

Step-by-step explanation:
If you plot the points on the graph, you notice that the run (change in x) is 3 for each "rise" (change in y) of -1, so the slope is ...
m = rise/run = -1/3
The middle point is on the y-axis, so is the y-intercept.
In slope-intercept form, the equation is ...
y = mx + b . . . . . . where m is the slope (-1/3) and b is the y-intercept (4)
y = -1/3x +4 . . . . equation
