Answer:
about 44 jumps per minute
Step-by-step explanation:
350/8=43.75
To know the slope of the line mark to points in the line and get the slope
I'll mark (0,0) , ( 6, 4)
the slope = (4-0) / (6-0) = 4/6 = 2/3
so the equation of this line is y=2/3x
the answer is C.)
C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x). Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>
To get the answer we can use proportion
40$ ------------- 100%
2$ ---------------- x
crossmultiply now
40x=2*100 /:40
x=200:40
x=5% - its the answer
Answer:
28.65% probability that the next customer will not arrive for 5 minutes
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Mean of 15 customers an hour:
An hour has 60 minutes, so in the space of 5 minutes, the mean is:
A customer walks in what is the probability that the next customer will not arrive for 5 minutes?
This is P(X = 0).
28.65% probability that the next customer will not arrive for 5 minutes
