How can you use 2, 3, 5 and 8 to get 104?

Tamiku [17]

Salma showed me how to do it.

Here are two ways:

8 times (5·3 - 2) = 8 times (15 - 2) = 8 times 13 = 104 .

8 times (5·2 + 3) = 8 times (10 + 3) = 8 times 13 = 104.

Thank you, Salma.

9th out 10 questions

Sloan [31]

The correct answer is 15.

This is because the relationship between x and y is y=3x, as can be verified by the other points in the table.

3 = 3(1), 6 = 3(2), 24 = 3(8).

When we plug in 5 for x into our equation, we get 3(5), which equals 15.

Therefore, your answer is 15.

Hope this helps!

Xelga [282]

Answer:

The expected number of days until prisoner reaches freedom is 12 days

Step-by-step explanation:

From the given information:

Let X be the random variable that denotes the number of days until the prisoner reaches freedom.

We can evaluate E(X) by calculating the doors selected, If Y be the event that the prisoner selects a door, Then;

E(X) = E( E[X|Y] )

E(X) = E [X|Y =1 ] P{Y =1} + E [X|Y =2 ] P{Y =2} + E [X|Y =3 ] P{Y =3}

$E(X) = (2 + E[X])\dfrac{1}{2}+ (4 + E[X])\dfrac{3}{10}+ 1 (\dfrac{2}{10})$

$E(X) = (2 + E[X])0.5+ (4 + E[X])0.3+ 0.2$

Solving for E[X]; we get

E[X] = 12
