Answer:
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we have
the points (−1,12) and (1,2)
substitute
step 2
we know that
The equation of the line in slope intercept form is equl to
where
m is the slope
b is the y-intercept
we have
substitute in the linear equation and solve for b
therefore
Answer:
(a) 12.87; 14; 18; (b) median
Step-by-step explanation:
(a) Statistics
(i) Mean
The mean is the sum of all the data points divided by the number of points.
(ii) Median
The median is the middle value in your list of observations.
0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20
Median = 14
(iii) Mode
The mode is the value that appears most often in your list of observations.
0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20
Mode = 18
(b) Most representative measure
The mean is dragged down by three low values. The median is the measure that is most representative of the data.
The histogram below shows the distribution of your data.
