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
Hours = 34
Income per hour = 12.5$
Service calls = 6
Income per call = 4
Therefore, total income
= (time of working * income per hour) + (service calls * income per call) = (34*12.5) + (6*4)
= 425+24
= 449
Answer:
D. 65
Step-by-step explanation:
180-50=130
130 divided by 2 =65
hope this helps:)
4/50 as a decimal is .08
Divide 4 by 50
