Any set that contains -1.5, whether finite or infinite.
For example,
the set consisting of only -1.5 ie {-1.5},
the set consisting of -1.5 and 5 = {-1.5,5},
the set consisting of -1.5 and 3 and sqrt(17) = {-1.5,3,sqrt(17)}, and so on.
The number 7.5 belongs to several mathematical sets, including the set of real numbers (ℝ) and the set of rational numbers (ℚ), as it can be expressed as the fraction 15/2. It is also part of the set of decimal numbers and the set of positive numbers. Additionally, it can be considered an element of the interval (7, 8).
The number that does not belong in this set is 77. All the other numbers are either multiples of 3, 5, or 7, while 77 is not a multiple of any of these numbers.
19 doesn't belong. The rest of the numbers are multiples of 3.
Well there are quite a few numbers that added together will equal negative 15: here are just a few examples: negative 1 plus negative 14 equals negative 15 (-1 + -14 = -15) negative 2 plus negative 13 equals negative 15 (-2 + -13 = -15) negative 3 plus negative 12 equals negative 15 (-3 + -12 = -15) negative 4 plus negative 11 equals negative 15 (-4 + -11 = -15) negative 5 plus negative 10 equals negative 15 (-5 + -10 = -15) negative 6 plus negative 9 equals negative 15 (-6 + -9 = -15) negative 7 plus negative 8 equals negative 15 (-7 + -8 = -15) negative 30 plus positive 15 equals negative 15 (-30 + 15 = -15) negative 29 plus positive 14 equals negative 15 (-29 + 14 = -15) negative 28 plus positive 13 equals negative 15 (-28 + 13 = -15) and on an on it goes.
115
Its a NEGATIVE number. A NEGATIVE INTEGER.
There are infinitely many such numbers. they belong to the set n*15 where n is any integer.
You can, of course, make up infinitely many sets that contain this number. Some important sets that include it are:The set of integers.The set of rational numbers.The set of real numbers.The set of complex numbers.
The number 7.5 belongs to several mathematical sets, including the set of real numbers (ℝ) and the set of rational numbers (ℚ), as it can be expressed as the fraction 15/2. It is also part of the set of decimal numbers and the set of positive numbers. Additionally, it can be considered an element of the interval (7, 8).
To any set that contains it! It belongs to {-15}, or {sqrt(2), -15, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
The number that does not belong in this set is 77. All the other numbers are either multiples of 3, 5, or 7, while 77 is not a multiple of any of these numbers.
