Calculate the average rate of change for the function f(x) = −x4 + 4x3 − 2x2 + x + 1, from x = 0 to x = 1.
Alekssandra [29.7K]
Really
just calculate the slope
slope is (y2-y1)/(x2-x1)

for x=0, y=1
for x=1, y=3

slope=(y1-y1)/(x-x1)=(3-1)/(1-0)=2/1=2

answer is 2

The average rate of job submissions in a busy computer center is 3 per minute. If it can be assumed that the number of submissio
san4es73 [151]

The probability that at least 40 jobs will be submitted in 15 minutes is <u>0.79162</u>.

The number of jobs submitted per minute follows Poisson Distribution.

A Poisson Distribution over a variable X, having a mean λ, has a probability for a random variable x as  P(X= x) = e^{-\lambda} \frac{\lambda^{x} }{x!} .

In the question, we have the random variable x = 40.

The mean λ = Average jobs per minute*time = 3*15 = 45.

We are to find the probability that at least 40 jobs will be submitted in 15 minutes, which is represented as P(X ≥ 40) = P(X > 39).

P(X > 39) = 1 - P(X ≤ 39) = 1 - poissoncdf(45,39)

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

Therefore, P(X > 39) = 1 - 0.20838 = 0.79162.

Therefore, the probability that at least 40 jobs will be submitted in 15 minutes is <u>0.79162</u>.
