Similarly a number of the form 10x + y is divisible by 7 if and only if x + 5y is divisible by 7. [8] So add five times the last digit to the number formed by the remaining digits, and continue to do this until a number is obtained for which it is known whether it is divisible by 7. [9] Another method is multiplication by 3.
Serial sevens (or, more generally, the descending subtraction task; DST), where a patient counts down from one hundred by sevens, is a clinical test used to test cognition; for example, to help assess mental status after possible head injury, in suspected cases of dementia or to show sleep inertia.
224: it is divisible by 2 and by 7. Add the last two digits to twice the rest. The answer must be divisible by 7. 364: (3 × 2) + 64 = 70." Well, I think there is a mistake. Obviously 371 is not divisible by 14 but (3×2)+71=77. Where it is written "The answer must be divisible by 7" it should be written "The answer must be divisible by 14".
Last year, district records show that 37% of students across Palm Beach County used the alternative test scores, often referred to as "concordant scores," to get their diplomas. But for some ...
A neuropsychological test used in the diagnosis of Alzheimer's disease. The subject gets one of more digits s/he has to cross out from a list of numbers. The resulting score consists of the correctly crossed out numbers minus the incorrectly crossed out numbers.
Study guides and strategies: Older drivers have a few tips for those who must take the dreaded California DMV renewal test, with all its 'obscure and ridiculous' questions
Confusing. Trivial. Useless. Laughable. Inconsistent. The road rage over DMV test questions continues for drivers 70 and older.
An integer is even if it is divisible by 2, and odd if it is not. [1] For example, −4, 0, and 82 are even numbers, while −3, 5, 7, and 21 are odd numbers. The above definition of parity applies only to integer numbers, hence it cannot be applied to numbers like 1/2 or 4.201.
