Answer:
x= 3/5 or x= 0.6
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a poisson distribution. Let x be a random representing the number of calls in a given time interval.
a) the expected number of calls in one hour is the same as the mean score in 60 minutes. Thus,
Mean score = 60/2 = 30 calls
b) The interval of interest is 5 minutes.
µ = 5/2 = 2.5
We want to determine P(x = 3)
Using the Poisson probability calculator,
P(x = 3) = 0.21
c) µ = 5/2 = 2.5
We want to determine P(x = 0)
Using the Poisson probability calculator,
P(x = 0) = 0.08
Start with he equation
3.5t + 4t = 4 - I did this since the walked the same amount of time and the total distanace covered was 4 miles
7.5t = 4
t = 0.53 hours
Answer:
(f+g)(x)=f(x)+g(x)=x²+2x+2
Step-by-step explanation:
f(x)=7
g(x)=x²+2x-5
(f+g)(x)=f(x)+g(x)=x²+2x+2
