Answer:

4 seats economic, 2 seats first class, 3 seats business class, 1 seat premium class

Step-by-step explanation:

4 \times economy class = 400$ +

2 \times first class = 300$ +

3 \times bussines class = 600$ +

1 \times premium class = 300$

= 1600$

<em>This </em><em>is </em><em>the </em><em>way </em><em>to </em><em>spend </em><em>the </em><em>least </em><em>money </em><em>if </em><em>everyone </em><em>is </em><em>seated </em><em>on </em><em>one </em><em>seat.</em><em> </em>

Calculate the expected value E(X) of the given random variable X. X is the higher number when two dice are rolled, or the common
Sati [7]

Answer:

4.4722

Step-by-step explanation:

The following table shows the 36 elements of the sample space of the experiment

\left[\begin{array}{cccccccc}&1&2&3&4&5&6\\--&--&--&--&--&--&--\\1\;|&1&2&3&4&5&6\\2\;|&2&2&3&4&5&6\\3\;|&3&3&3&4&5&6\\4\;|&4&4&4&4&5&6\\5\;|&5&5&5&5&5&6\\6\;|&6&6&6&6&6&6\end{array}\right]

From this table we can compute the probabilities :

P(X = 1) = 1/36

P(X = 2) = 3/36

P(X = 3) = 5/36

P(X = 4) = 7/36

P(X = 5) = 9/36

P(X = 6) = 11/36

So the expected value equals

1P(X=1)+2P(X=2)+3P(X=3)+4P(X=4)+5P(X=5)+6P(X=6) =

= 1/36 + 6/36 + 15/36 + 28/36 + 45/36 + 66/36 = 161/36 =

The function ƒ(x ) = -3x + 5 is represented by which set of ordered pairs?
ozzi

Answer:

The correct answer is the first set {(-1, 8), (0, 5), (2, -1), (3, -4)}

Step-by-step explanation:

In order to determine if the set works, input each ordered pair to see if the statement ends up true. The first two ordered pairs are done below.

(-1, 8)

f(x) = -3x + 5

8 = -3(-1) + 5

8 = 3 + 5

8 = 8 (TRUE)

(0, 5)

f(x) = -3x + 5

5 = -3(0) + 5

5 = 0 + 5

5 = 5 (TRUE)
