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
To simplify interval notation, you combine overlapping or contiguous intervals into a single interval if possible. For example, if you have the intervals [2, 5] and [4, 7], you can simplify them to [2, 7]. Additionally, remove any redundant elements, such as expressing (3, 5) ∪ (5, 7) simply as (3, 7) since the endpoints do not overlap. Always ensure that the final interval is expressed in the correct format, using parentheses for open intervals and brackets for closed intervals.
[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?
The number 1315171921 can be expressed in set builder notation as the set of all individual digits: {1, 2, 3, 5, 7, 9}. Using roster method, this can be written as: {1, 1, 1, 2, 1, 5, 1, 7, 1, 9}. However, to avoid repetition in set notation, we simplify it to {1, 2, 5, 7, 9}.
a builder notation is like this < x/x is a set of nos. up to 7>
7/3
The inequality ( x < 7 ) defines the interval ( (-\infty, 7) ). This means that all real numbers less than 7 are included in the solution set, while 7 itself is not included. Conversely, if the inequality were ( x > 7 ), it would define the interval ( (7, \infty) ).
The numeric interval of 5-7 is greater.
