If there are 30.48cm in a foot and 12cm represents 102 feet then 12 cm represents 3109cm or 12:3109. Divide both sides by 12 to get the scale and it is: 1:259, the scale is 259.
Hope this helps :)
The piecewise function tells us to use 3x-5 if the input (x-value) is anything greater than or equal to -4. Let's just plug in -3 for x and that will be your answer:
Therefore, your answer is A, -14.

The median is 7.
——————————
Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
