Which has greater absolute value -15 or -14?
-1
Which number does not belong 12 13 14 15 16?
13, it's the only prime. All the other ones can be divided by something other than 1.
What number goes into 14 and 15?
The two number have no common prime factors. i.e. the HCF(14, 15) = 1; they are coprime.
Which number doesn't belong 2-4-5-10-15-20-25-50?
15
Which number does not belong in the series 2-3-6-7-8-14-15-30?
8 does not belongSequence is to add 1 for the first number, and double the next result, and then add 1 to that result, and double again...Correct Sequence2 (+1) 3 (x2) 6 (+1) 7 (x2) 14 (+1) 15 (x2) 302-3-6-7-8-14-15-30(2+1) = (3 x 2) = (6 + 1) = (7 x 2) = (14 + 1) = (15 x 2) = 30 ....So 8 does not belong in the above series.
Which number does not belong in the sequence 2-3-6-7-8-14-15-30?
8
What number doesnt belong 3 7 11 15 31?
31 because 3+4=7+4=11+4=15+4 does not equal 31
2 - 3 - 6 - 7 - 8 - 14 - 15 - 30 which does not belong?
The 8 does not belong. The sequence of numbers alternates adding 1 to the previous number and doubling the previous number. 2 3 = 2 + 1 (adds 1 to previous number) 6 = 3 x 2 (doubles previous number) 7 = 6 + 1 (adds 1 to previous number) 14 = 7 x 2 (doubles previous number) 15 = 14 + 1 (adds 1 to previous number) 30 = 15 x 2 (doubles previous number)
How is nitrogen 14 similar to nitrogen 15?
Nitrogen-14 and nitrogen-15 are both isotopes of nitrogen, meaning they have the same number of protons but a different number of neutrons. They both belong to the same chemical element and share similar chemical properties. The main difference between them is their atomic mass, with nitrogen-15 having one extra neutron compared to nitrogen-14.
Which has greater absolute value -15 or -14?
-1
Which doesnt belong 1 5 10 15 20 25 50 100 and why?
1, because all the numbers are factors of 5.* * * * *Or 5: it is the only prime number.Or 15: it is the only number that is not a factor of 100Or 25: it is the only number with three factorsOr 100: it is the only number with 9 factors
Which number does not belong 12 13 14 15 16?
13, it's the only prime. All the other ones can be divided by something other than 1.
Why does nitrogen have a mass number of 15?
It does not, the mass number of nitrogen is 14 not 15.
What is the mass number of an element that has 14 electrons and 15 neutrons?
The mass number is equal to the sum of protons and neutrons in an atom. Since the element has 14 electrons and 15 neutrons, it must have 15 protons (atomic number is equal to number of protons). So, the mass number would be 15 + 15 = 30.
What number goes into 14 and 15?
The two number have no common prime factors. i.e. the HCF(14, 15) = 1; they are coprime.
Which number doesn't belong 2-4-5-10-15-20-25-50?
15
How many neutrons are in 28Al?
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
