Answer:
The number is 4
Step-by-step explanation:
Let the number = 'x'
Reciprocal of 'x' = 1/x
Reciprocal of 2 = 1/2
8 times the reciprocal of 'x' = 

Now multiply both sides by x

Now divide both sides by 2

x = 4

Step-by-step explanation:
<u>Functions and Relations</u>
A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).
By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option

Answer:
B is symmetric; A is not.
Step-by-step explanation:
Since you did part A, you know that the ends of each box are roughly symmetrically located with respect to the extremes of data in each case. However, the median of the data for School A is decidedly near the right end of the box; whereas the median for School B is in the center of the box.
This last fact gives the box plot for School B a symmetric appearance that is not shared by the plot for School A.
