Answer: The mean temperature for the first eight days is 6.5 degrees
Step-by-step explanation: The most important piece of clue has been given which is the mean (average) for the observed data set, which is 7 days.
Note that the formula for the mean of a data set is derived as;
Mean = ∑x / f
Where ∑x is the summation of all observed data set and f is the number of data observed, that is 7. The formula now becomes;
6 = ∑x / 7
By cross multiplication, we now have,
6 * 7 = ∑x
42 = ∑x
This means the addition of all temperature observed on the first 7 days is 42. The temperature on the eighth day is now given as 10 degrees, this means the summation of all observed data for the first eight days would become 42 + 10 which equals 52. Therefore when calculating the mean for the first eight days, ∑x is now 52. The formula for the first eight days therefore is derived as follows;
Mean = ∑x / 8
Mean = 52 / 8
Mean = 6.5
The calculations therefore show that the mean temperature for the first eight days in January is 6.5 degrees
A=A(1+r/100)^t
a=17000(1+.043)^3
a=19.288.65

In set theory<span>, the </span>complement of a set A<span> refers to </span>elements<span> not in </span>A<span>. The </span>relative complement<span> of </span>A<span> with respect to a set </span>B<span>, written </span><span>B \ A</span><span>, is the set of elements in </span>B<span> but not in </span>A<span>. When all sets under consideration are considered to be </span>subsets<span> of a given set </span>U<span>, the </span>absolute complement<span> of </span>A<span> is the set of elements in </span>U<span> but not in </span>A<span>.
</span>The empty set<span> is the </span>set<span> containing no elements. In mathematics, and more specifically </span>set<span> theory, the </span>empty set<span> is the unique </span>set<span> having no elements; its size or cardinality (count of elements in a </span>set<span>) is zero.

Roster Form<span>: This method is also known as tabular method. In this method, a set is represented by listing all the elements of the set, the elements being separated by commas and are enclosed within flower brackets { }. Example: A is a set of natural numbers which are less than 6.
</span>
Set-Builder Notation<span>. A shorthand used to write </span>sets<span>, often </span>sets<span> with an infinite number of elements. Note: The </span>set<span> {x : x > 0} is read aloud, "the </span>set<span> of all x such that x is greater than 0." It is read aloud exactly the same way when the colon : is replaced by the vertical line.
