The probability that the digits display a palindrome = 19/240 Ans.
As we know the total no. of possible hours = 12
Total number of possible minutes= 60
Therefore, total no. of possible times that can be shown are = 12
Since total no. of Palindromes possible per hour for the nine hours 1 through 9 = 6
No. of palindromes per hour from 10 through 12 = 1
Therefore, total no of palindromes = (6*9) + 3 = 57
Probability that the digits display a palindrome = 57/720 = 19/240
Answer:
Step-by-step explanation:
Let the age be xy or 10x + y.
Reverse the two digits of my age, divide by three, add 20, and the result is my age, convert this to equation:
- (10y + x)/3 + 20 = 10x + y
- (10y + x)/3 = 10x + y - 20
- 10y + x = 3(10x + y - 20)
- 10y + x = 30x + 3y - 60
- 30x - x + 3y - 10y = 60
- 29x - 7y = 60
We should consider both x and y are between 1 and 9 since both the age and its reverse are 2-digit numbers.
Possible options for x are:
- 29x ≥ 7*1 + 60 = 67 ⇒ x > 2, at minimum value of y,
and
- 29x ≤ 7*9 + 60 = 123 ⇒ x < 5, at maximum value of y.
So x can be 3 or 4.
<h3>If x = 3</h3>
- 29*3 - 7y = 60
- 87 - 7y = 60
- 7y = 27
- y = 27/7, discarded as fraction.
<h3>If x = 4</h3>
- 29*4 - 7y = 60
- 116 - 7y = 60
- 7y = 56
- y = 8
So the age is 48.

Answer:
A function
Step-by-step explanation:
The question is needed, but with the statement it can be determined that this situation would be, if a relationship or function, or given the case of both or neither.
Let's first define what a relationship is, define that a single input can have more than one output, applied to the statement would be that if you apply the same force in two different situations, the amount of candy that comes out may be different.
On the contrary, in a function for each input there is an output, a possible result, which is what they tell us in the statement.
Therefore this situation is represented by a function.
