5 0

ANSWER

2{m}^{3}

EXPLANATION

The expressions are

8 {m}^{3}  =  {2}^{3}  \times  {m}^{3}

and

6 {m}^{4}  = 2 \times 3 {m}^{4}

The greatest common factor is the product the least powers of the common factors.

= 2 {m}^{3}

Question 12<br> Simplify.<br> 54.8-6.9-12<br> 5-2.83.9-4.
trapecia [35]

Answer:

366.

-1493.

Step-by-step explanation:

54.8-6.9-12

You perform the multiplications first:

= 432 - 54 - 12

= 378 - 12

= 366.

5-2.83.9-4

=  5 - 166* 9 - 4

= 5 - 1494 - 4

= -1489 - 4

= -1493

A red die and a blue die are rolled. You win or lose money depending on the sum of the values of the two dice. If the sum is 6 o
olganol [36]

Answer:

The expected value of X is $0.0833.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

For each dice, there are 6 possible outcomes(values from 1 to 6). So for 2 dices, there are 6^2 = 36 desired outcomes.

Desired outcomes:

Sum 5: (1,4), (2,3), (3,2), (4,1).

Sum 6: (1,5),(2,4),(3,3),(4,2),(5,1)

Sum of 9: (3,6), (4,5), (5,4), (6,3)

Sum of 10: (4,6), (5,5), (6,4)

Sum of 12: (6,6)

Probabilities:

5 + 3 = 8 outcomes in which the sum is 6 or 10, that is, 8/36 probability of winning $4.

4 + 4 + 1 = 9 outcomes in which the 5, 9, or 12, that is, 9/36 probability of winning $1.

36 - (8 + 9) = 36 - 17 = 19 remaining outcomes, that is, 19/36 probability of losing $2.

What is the expected value of X?

Multiplication of each outcome by its probability. So

E(X) = \frac{8}{36}*4 + \frac{9}{36}*1 - \frac{19}{36}*2 = \frac{8*4 + 9*1 - 19*2}{36} = \frac{32 + 9 - 38}{36} = \frac{3}{36} = 0.0833

The expected value of X is $0.0833.
