Answer:

Statements I & II

Step-by-step explanation:

If each dog costs about $2.40 in food expenses than you would multiply that by the number of dogs you have. So x represents the possible number of dgos.

The 30 represents the other daily expenses that the shelter has to each day.

Answer:

Bud have eaten 2 pieces as Bud and Dotti have eaten exact same amount.

Step-by-step explanation:

We have been given Dotti and Bud bought two identical watermelons

Dotti cut her watermelon into 3 pieces and ate 2 of the pieces.

Bud cut watermelon into 9 pieces

But Dotti and Bud have eaten exact same amount of watermelon

That means if Dotti have eaten 2 pieces then Bud would also have eaten 2 pieces out of 9.

Let X = the time between two successive arrivals at the drive-up window of a local bank. If X has an exponential distribution wi

Illusion [34]

Answer:

(a) $E(X) = 1$

(b) $\sigma_X =1$

(d) P(2 ≤ X ≤ 5) = 0.1286

Step-by-step explanation:

From the given information; Let consider X to be the time between two successive arrivals at the drive-up window of a local bank.

However; If X is regarded as the exponential distribution with λ = 1 which is identical to a standard gamma distribution with ∝ = 1

The objective is to compute the following :

(a) The expected time between two successive arrivals is;

$E(X) = \dfrac{1}{\lambda}$

$E(X) = \dfrac{1}{1}$

$E(X) = 1$

(b) The standard deviation of the time between successive arrivals is;

$\sigma_X = \sqrt{\dfrac{1}{\lambda^2}}$

$\sigma_X ={\dfrac{1}{\lambda}}$

$\sigma_X ={\dfrac{1}{1}}$

$\sigma_X =1$

P(X ≤ 1) = 1 - e⁻¹

P(X ≤ 1) = 0.6321

(d) P(2 ≤ X ≤ 5)

P(2 ≤ X ≤ 5) = [1 - e⁻⁵] - [1 - e⁻²]

P(2 ≤ X ≤ 5) = 0.9933 - 0.8647

P(2 ≤ X ≤ 5) = 0.1286
