Select two choices: one for the center and one for the spread.
Answers
Answer:
The best measure of location or center is the median.
The best measure of spread or dispersion is the interquartile range (I.Q.R).
Step-by-step explanation:
The data set is skewed to the left since most of the data values fall in the upper end of the distribution. In other words the data set is negatively skewed since it is tailed to the left.
For any skewed data set;
The best measure of location or center is always the median. This is because the median is robust to outliers unlike the mean.
On the other hand, the best measure of spread or dispersion is the interquartile range (I.Q.R).

Answer:
Choice C) no solutions
=============================
Work Shown:
y+7 = 3x turns into y = 3x-7 after we subtract 7 from both sides
Plug that into the other equation and solve for x
------
6x - 2y = 12
6x - 2( y ) = 12
6x - 2( 3x-7 ) = 12 ... y replaced with 3x-7
6x - 2(3x) - 2(-7) = 12
6x - 6x + 14 = 12
0x + 14 = 12
0 + 14 = 12
14 = 12 ... this is a contradiction, aka false statement
------
No matter what x value we pick, the equation above will always be false.
Therefore, there are no solutions
We say that this system of equations is inconsistent.
Graphing both equations leads to two parallel lines. A solution only happens if the lines cross, but parallel lines never intersect.

What is the equation of a line?
The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation of a line is y=1/2x+5.
Substitute x=0, 1, 2, 3, 4, 5,....in a equation y=1/2x+5, we get
When x=0, y=5
When x=1, y=5.5
When x=2, y=6
When x=3, y=6.5
When x=4, y=7
So, the coordinate points are (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7)
Therefore, the graph for the coordinate points (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7) is plotted below.

Answer:
Step-by-step explanation:
Y/1 = 2x + 5
Y = 2x + 5
Y = 2x + 5
When x = 1
Y = 2 ×1 +5
Y = 2 + 5
Y = 7
When x =0
Y = 2 × 0 + 5
Y = 5
When x = -2
X = 2 × -2 + 5
X = 1
