Answer:

y = (-5/2)x + 1

Step-by-step explanation:

y = (-5/2)x + c

When x = 2, y = -4

-4 = (-5/2)(2) + c

-4 = -5 + c

c = -4 + 5 = 1

y = (-5/2)x + 1

A local animal rescue organization receives an average of 0.55 rescue calls per hour. Use the Poisson distribution to find the p
andreyandreev [35.5K]

Answer:

B) 0.894

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:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

A local animal rescue organization receives an average of 0.55 rescue calls per hour.

This means that \mu = 0.55

Probability that during a randomly selected hour, the organization will receive fewer than two calls.

P(X < 2) = P(X = 0) + P(X = 1)

In which

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-0.55}*(0.55)^{0}}{(0)!} = 0.577

P(X = 1) = \frac{e^{-0.55}*(0.55)^{1}}{(1)!} = 0.317

P(X < 2) = P(X = 0) + P(X = 1) = 0.577 + 0.317 = 0.894

klio [65]

Answer:

The rate is \frac{2}{5} degree per hour.

Step-by-step explanation:

Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose \frac{1}{10} degree every \frac{1}{4} hour for a limited time.

To find : What was the rate, in degrees per hour that the temperature of the compound rose ?

Solution :

In every \frac{1}{4} hour the temperature of a compound rose \frac{1}{10} degree

To get  the rate, in degrees per hour,

In every 1 hour the temperature of a compound rose is

r=\dfrac{\frac{1}{10}}{\frac{1}{4}} degree

r=\dfrac{4}{10} degree/hr

r=\dfrac{2}{5} degree/hr

Therefore, the rate is \frac{2}{5} degree per hour.
