Two dice are rolled one after another. Construct a sample space and determine the probability that the sum of the dots on the dice total a number greater than 9 if the second die is a 5. The probability that the sum of the dots on the dice is a number greater than 9 if the second die is a 5 is nothing.(Type an integer or a simplified fraction.)

Answer:
The answer is 4.69 sec
Step-by-step explanation:
We know time taken = distance / speed
here 1 mile = 5280 feet , so 767 mph = 767x 5280 feet /( 60x60 ) s = 1124.93 feet / sec .
now , time taken
It will take 4.69 sec for the sound to travel 1 mile or 5280 feet .

If you round up to 10:10, it's a little easier. Picture an analog clock in your head. Every big number is five minutes, and every two is ten minutes. If we put it back to the 12, that's ten minutes back. Twenty minutes earlier from that would be 9:40. Since we added two minutes to make it easier, we've got to subtract those two minutes. So, the starting time would be 9:38.
I hope this isn't too confusing.

Answer:
13 is the prime number
Step-by-step explanation:
You must take into account that a prime number is one that is just divisible by 1 and itself. So, let's analyse each number.
Number 14
If you divide 14 by 1 you obtain 14.
If you divide 14 by 14 you obtain 1.
If you divide 14 by 2 you obtain 7.
If you divide 14 by 7 you obtain 2.
14 is not prime because is divisible by 1, 2, 7, and 14
Number 13
If you divide 13 by 1 you obtain 13.
If you divide 13 by 13 you obtain 1.
13 is a prime number because it can't be divided by other number, just 1 and itself
Number 21
If you divide 21 by 1 you obtain 21.
If you divide 21 by 21 you obtain 1.
If you divide 21 by 3 you obtain 7.
If you divide 21 by 7 you obtain 3.
21 is not prime because is divisible by 1, 3, 7, and 21
Number 33
If you divide 33 by 1 you obtain 33.
If you divide 33 by 33 you obtain 1.
If you divide 33 by 3 you obtain 11.
If you divide 33 by 11 you obtain 3.
33 is not prime because is divisible by 1, 3, 11, and 33
Thus, 13 is the prime number
No even numbers can be primes because they are all divisible by 2.
Therefore, 14 is not a prime number.
21 ÷ 3 = 7
33 ÷ 3 = 11
That leaves 13.
13 is a prime number.
A. –243
B. –27
C. –4
D. 4
Answers
3^-243=0
So, A. isn't correct.
3^-27=1.31137265.....
So, B. isn't correct.
3^-4=0.123456789 In fraction form this is 1/81
So, we think C. is the correct answer, but just to be sure, let's try D.
3^4=81 In fraction form this would be 81/1.
So, C. is our answer.
Hope this helps!!
