Answer:
2.24
Step-by-step explanation:
The probability formula using a Poisson distribution is:
λ = 90 / 18 = 5 average goals per interval (interval = a game)
So if for example you were interested in the probability of making 2 goals in a game
k = 2
This was just an example,
The standard deviation is
Answer:
1
Step-by-step explanation:
Gradient (slope) = change in y / change in x
(6-5) / (3-2) = 1/1 = 1
The gradient is 1
Answer:
N=48
Step-by-step explanation:
2^9+2^4+48=576
576 is a perfect square
40 miles an hour
60 [minutes] * 60 [seconds]= 3600
22.5[seconds for 1/4 of a mile]* 4[ one mile]= 90 [seconds per mile]
3600/90=40 [miles an hour]
