You test if the last two digits are divisible by 4. If the digit in the tens' place is odd, the digit in the units place must be 2 or 6. If the digit in the tens' place is even, the digit in the units place must be 0, 4 or 8.
The first digit in the five-digit Enteropluri test ID value being equal to or greater than 4 indicates that the organism is a member of the Enterobacteriaceae family, which is essential for accurate identification. Similarly, the fourth digit in the API 20E profile number being equal to or greater than 4 signifies that the test results correspond to specific biochemical characteristics typical of enteric bacteria. This standardization ensures reliable and consistent interpretation of test results, facilitating proper identification and diagnosis.
a scale which takes the combined scores of the written test and compares this with the chronological age of the tester. this gives the number called the IQ. 100 is considered average.
No. To test if a number is divisible by 8: * first all multiples of 8 are even, so the number must be even; * then: add 4 times the hundreds digit to twice the tens digit to the ones digit - if this sum is divisible by 8, then so is the original number. As the test can be applied to the sum, repeating this summing until a single digit remains, only if this single digit is 8 is the original number divisible by 8. For 100: 4x1 + 2x0 + 0 = 4 which is not 8, so 100 is not divisible by 8.
