Help me on 12 and 13 please
1 answer:
Answer:
12. h=3
13. h=-3
Step-by-step explanation:
12. Recall that is a horizontal shift since h is being applied within the operation to the input. This means that h will slide the function left or right. Since the function f has a point at (1,-2) and g has the same point at (4,-2) then the function has moved 3 units 1+3=4 to the right. h=3.
13. Once again, h is a horizontal shift meaning the graphs has moved left or right only. Looking at g it has a point at (-2,2) while f has the same point at (1,2). So the graph f has moved to the left 3 units. This is h=-3 since 1+-3 = -2.

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.
