I got the degree to be 81.81818182 I just don't know how get the minute please do tell how to solve by using calculator or by paper thank you

Answers

Well a clock has twelve hours that make up a full circle, or 360 degrees, so you divide 12 by 360 then multiply by the degree, which in this case is 81.81 and that's the number of hours. (You figure out the minutes by looking at the decimal)

Find the probability of getting a doublet in a throw of a pair of dice.

Answers

There are six ways to roll 2 dice such that both dice have the same value
These are the outcomes (1,1),(2,2),(3,3),(4,4,)(5,5) and (6,6).

To find the total number of outcomes, note that there are 6 choices for the first die (values 1–6) and there are 6 choices for the second die (again values 1–6) and so by the Multiplication Principle (MP) there are 36 total outcomes from rolling two dice once.

Now we have the following:

P(getting a doublet) =
Total number of outcomes
Number of ways to get double

=
36
6

=
6
1

Thus, the probability of getting a doublet is
6
1

.

Question:

Find the probability of getting a doublet in a throw of a pair of dice.

Answer:

The probability is 1 out of 6.

Explanation:

There are a total of 6 possibilities that you get a doublet, which is {1, 1}, {2, 2}, {3, 3}, {4, 4}, {5, 5}, and {6, 6}.

The total possibilities of throwing a dice are 6 possibilities for the first dice, and 6 possibilities for the second dice. Which results in a total of 6 × 6 = 36 possibilities available.

Probability = Possibilities of getting doublet ÷ Total possibilities = 6 ÷ 36 = 1 ÷ 6.

Hopefully this answer will help you.

The list price of a refrigerator is $1899. The chain discount is 20/15. What is the final net price?

Answers

1st = 100% - 20% = 80%
2nd= 100%-15% = 85%

Net Price Factor = 0.8 x 0.85 = 0.68

Net Price = $1899 x 0.68

Final Net Price = $1,291.32

Total Discount= $1899 - 1,291.32 = $607.68
