Answer:
-409
Step-by-step explanation:
At the beginning - 12,135 subsribers,
Initial number of subsribers = 12,135
At the end - 10,090 subsribers
Final number of subsribers = 10,090
Time = 5 years.
So, the average yearly rate of change is
The number of subscribers decreases by 409 per year
the length of c is 18.43909
pythagorean therorem
angles 1 4 and 5 are all equal to 113 and angles 2 3 6 and 7 equal 67
P(z>1.3) = 0.9032
We are given:
Mean = 5000
Standard deviation = 1000
x = 6300
P(x>6300)=?
z-score =?
z-score = x- mean/standard deviation
z-score = 6300 - 5000/1000
z- score = 1300/1000
z-score = 1.3
So, P(x>6300) = P(z>1.3)
Looking at the z-probability distribution table and finding value:
So, P(z>1.3) = 0.9032
