Step-by-step explanation: The score is between 35 and 40. These scores are 36, 37, 38, 39. If the number is divisible by 2 , therefore it is an even number. These even numbers are 36 and 38. The score is not divisible by 4 and 6. The score divisible by both 4 and 6 is 36. Therefore the score divisible by 2 but not divisible by both 4 and 6 is 38. Divisibility Rule: Of #2: If a number is even, it is divisible by 2. Even numbers are numbers with ones digits 0,2,4,6,8. Of #4: If the the sum of the last two digits of a number (the tens and ones digits) is divisible by 4, the number is divisible by by 4. Example: The number is 316.
