Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :
The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
Graph A because the graph starts out at 10 on week one and goes up by ten each week
A stem and leaf plot (histogram) shows the mode as the longest list of "leaves." It is the easiest to use for finding mode.
A box-and-whisker plot tells you nothing about relative frequencies.
A scatter plot or line graph would require careful re-interpretation to determine the mode. If the amount of data is large and there are many data values with about the same high frequency, these charts may be unhelpful, too.
