-7 -3 is not an interval set notation. In general, an interval set notation consists of two brackets: either round () or square [] within which are two numbers. The infimum of the interval first, separated by a comma from the supremum. It is also necessary to define the superset of which the interval is a subset: it could, for example, be integers, rationals or reals.
A round bracket indicated a strict inequality, a square bracket indicated an inequality that is not strict.
The terms infimum and supremum are used rather than minimum and maximum because, if the inequality is strict, the numbers will not belong to the set.
Thus, for example,
[-7, -3) is equivalent to -7 ≤ x < -3, while
(-7, -3] is equivalent to -7 < x ≤ -3
where x is a Real number.
In the first example, -3 does not belong to the set and so cannot be said to be the maximum value in the set.
7,000 in scientific notation is 7.0*10^3
23/3 or 7 and 2/3
A list of elements, separated by commas, enclosed in curly braces. Example: {3, 5, 7} is the set of single-digit odd prime numbers. Tricky Example: { { }, {3}, {5}, {7}, {3,5}, {3,7}, {5,7}, {3,5,7} } is the set of subsets of the set of single-digit odd prime numbers. Notice that every element of this set is itself a set. The roster notation allows the use of nested curly-braces to describe sets which have other sets as elements. Infinite set in roster notation: {1, 2, 3, ...} is the set of positive integers. The first few elements illustrate the pattern, and the ellipsis (three dots) indicate that the pattern continues indefinitely.
An interval is a "set of real numbers." In other words say you had a problem like [5....1]. This means that everything between the 5 and the 1 are a set of real numbers (including the 5 and 1). Or like [-7, 9].
7
[2,7] the bracket means inclusive but if it said exclusive it would have parenthesis replacing the brackets.
The default no-refresh interval is set to: 7 days.
what is the fractional notation of 3 3/7?
a builder notation is like this < x/x is a set of nos. up to 7>
7/3
The numeric interval of 5-7 is greater.
The numeric interval of 5-7 is greater.
52/7
1 - 8, unless there is a logical reason for another interval.
7,000 in scientific notation is 7.0*10^3
7 = (7 x 1)3 = (3 x 1)
30 million in scientific notation is written as 3 x 10^7.
