A professor receives, on average, 24.7 emails from students the day before the midterm exam. To compute the probability of recei

MaRussiya [10]

Answer:

Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is $X \sim Poisson(\lambda=24.7)$

The probability mass function for the random variable is given by:

$f(x)=\frac{e^{-\lambda} \lambda^x}{x!} , x=0,1,2,3,4,...$

The best answer for this case would be:

C. Poisson distribution

Step-by-step explanation:

Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is $X \sim Poisson(\lambda=24.7)$

The probability mass function for the random variable is given by:

$f(x)=\frac{e^{-\lambda} \lambda^x}{x!} , x=0,1,2,3,4,...$

And f(x)=0 for other case.

For this distribution the expected value is the same parameter $\lambda$

$E(X)=\mu =\lambda$

And for this case we want to calculate this probability:

$P(X \geq 10)$

The best answer for this case would be:

C. Poisson distribution

At wet pets, a starter tree aquarium kit cost $15 plus $.60 per fish. At grips and frills, the same kit is $13 plus $.80 per fis

Katena32 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

Write an equation for the cost of fish at each fish store.

a) Wet pets

We must consider the initial price and the cost of each fish.

total cost = C

kit cost = $15

cost of each fish = $0.60

cost of one fish = f

C = 15 + 0.60f

Example, if the number of fish is 4, then the total cost will be

C = 15 + 0.60(4)

C = 15 + 2.4

C = $ 17.4

b) Grips and Frills

total cost = C

kit cost = $13

cost per fish = $0.80

cost of one fish = f

Equation

C = 13 + 0.8f
