Answer:

D.

Step-by-step explanation:

A function, by the easy-to-understand definition, is a relation where no x values are shared.  The only set where each x value is different is in D.  All the other sets share the same x value.  Example:  Set C has coordinates (-2, 1) and (-2, 2).  The x coordinates are the same, so this isn't a function.  It is only a relation.

Answer:

\huge\boxed{\bf\:c = \frac{11}{4}}

Step-by-step explanation:

4c + 2c = 4c + \frac{11}{2}

Cancel 4c on both the sides of the equation.

2c = \frac{11}{2}

Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

2*2c = 11\\4c = 11

Bring 4 to the right hand side if the equation.

\boxed{\bf\:c = \frac{11}{4}}

Consider the characteristics of the graph. Which statement DOES NOT describe the data set?
serg [7]
A, the interquartile range is 10, does not fit.

The interquartile range is found by subtracting the upper quartile and the lower quartile; in a box-and-whisker plot these are the outer edges of the box.  In this case, they are 40 and 20; 40-20 = 20, not 10.
