You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)
← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
4:2 can represented as 4 / 2. Or also 2.
30 / 2 = 15
Answer: C,D are true
Step-by-step explanation:
Pieces of data such as $18,000 and $350,000 represent outliers in this chart in standard deviation .
How to interpret a standard deviation?
- The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
- The standard deviation calculates how much the data vary from the mean value. It is helpful for contrasting data sets that might have the same mean but a different range.
In this chart, there are outliers. The main outliers are $18,000 and $350,000. This is because we know the mean or average is $63,423, and therefore values that are too different from this average are considered outliers.

Mixed numbers are greater than one. it wouldn't make sense for a mixed number to be less than one, because then it would just be a regular fraction.
you can only get a bigger number if you divide by a number less than one. that means you can't divide 15 by a mixed number and get a bigger number.
