Vesna [10]

Answer:

0.184

Step-by-step explanation:

As the statistician consultant, I would have to calculate the chance of having 2 ambulances on the freeway at this hours and relay the message to the dispatcher.

Probability of having the need for 2 ambulances.

We will have a poisson distribution:

Lambda = 1

P(x=2) = e^-2*1/2!

= 2.71828^-1/2

= 0.368/2

= 0.184

I would tell the dispatch rider that the possibility that 2 ambulances would be required is 0.184.

Thank you

What is the minimum number of cards that must be drawn from an ordinary deck of cards to guarantee that you have been dealt at l

irina1246 [14]

The minimum number of cards which must be drawn to get atleast 3 cards of aces is 4.

According to the given question.

We have a deck of cards.

As, we know that

The total numbers of cards in a deck = 52

Since, we have to find the minimum number of cards to be drawn so that we will get atleast 3 cards of aces.

As they have used atleast in the question so the cards can be more also so we have to reach at minimum number of cards to be drawn to guarantee atleast 3 cards of aces.

Number of suits in a standard deck= 4 (Clubs, Hearts, Diamond, Spades)

Number of aces in a suit = 1

We need atleast three cards of aces. Which means that we have 4*1 =4 cards from each suit.

Thereofre, the minimum number of cards which must be drawn to get atleast 3 cards of aces is 4.

What is the simplest form of 3√27a3b7

Anni [7]

Answer:

$3ab^2\sqrt[3]{b}$

if the problem was $\sqrt[3]{27a^3b^7}$ .

Step-by-step explanation:

Correct me if I'm wrong by I think you are writing $\sqrt[3]{27a^3b^7}$ .

$\sqrt[3]{27a^3b^7}$

I'm first going to look at this as 3 separate problems and then put it altogether in the end.

Problem 1: $\sqrt[3]{27}=(3)$ since $(3)^3=27$ .

Problem 2: $\sqrt[3]{a^3}=(a)$ since $(a)^3=a^3$

Problem 3: $\sqrt[3]{b^7}$ . This problem is a little harder because $b^7$ is not a perfect cubes like the others were. But $b^7$ does contain a factor that is a perfect cube. That perfect cube is $b^6$ so rewrite $b^7$ as $b^6 \cdot b^1$ or $b^6 \cdot b$ .

So problem 3 becomes $\sqrt[3]{b^6 \cdot b}=\sqrt[3]{b^6}\cdot \sqrt[3]{b}=b^2 \cdot \sqrt[3]{b}$ . The $b^2$ came from this $(b^2)^3=b^6$ .

Anyways let's put it altogether:

$3ab^2\sqrt[3]{b}$
