<u>Relations and Functions</u>
A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.
From the options presented below, we'll mark as functions only those who don't have relations between one element in the input set with more than one element in the output set.
In the first relation, every input element is related to only one output element. The same occurs in the second relation.
Note that in the third relation, the input element -5 is related to 4 and also to -4. Element -3 is also related to two different elements. This is not a function.
The fourth relation has the input element 1 related to two different output elements in the pairs (1,0) and (1,2). Thus, this is not a function either.
The fifth relation is a function. No input element is related to more than one output element.
Summarizing the options to select are shown below.
Answer:
Let X be the number of customer purchased coffee
Let Y be the number of customer purchased donuts
Then is the number of customer purchased both coffee and donuts
is the number of customer purchased both coffee or donuts
<em><u>The Number of customers purchased only Coffee:</u></em>
Number of customers purchased only donuts =n(X -Y)
n(X-Y) = 59 -16
n(Y - X) = 43
<em><u>The Number of customers purchased only donuts:</u></em>
Number of customers purchased only donuts =n(Y -X)
n(Y - X) = 39 -16
n(Y - X) = 23
<u>The Number of customers did not purchase either of these items:</u>
Number of customers did not purchase either of these items =
First lets find
= = 28

Answer:
arc FG = 115°
arc EG = 165°
Step-by-step explanation:
The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.
arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc
80° + arc FG = 195°
arc FG = 115° . . . . . . . . . subtract 80°
__
Similarly, parts of a circle add to give the whole circle.
arc EFG + arc EG = 360°
195° + arc EG = 360°
arc EG = 165° . . . . . . . . . subtract 195°
