Answer:
The mean or average is 9.5 for this set of data. The median is 10.5 and the range is 5.
Answer:
Perimeter ratio: 11:6
Area ratio: 121:36
Step-by-step explanation:
The ratio of length of the perimeter of one similar figure to another is the ratio of the side lengths.
The ratio of the areas is the ratio of the squares of the side lengths.
Answer:
, the third one
Step-by-step explanation:
Explaining the sine function:
The sine function is defined by:

In which A is the amplitude,
is the period,
is the horizontal shift and V is the vertical shift.
So, in your problem:
The amplitude is 4, so A = 4.
The period is
, so
.
There is no horizontal shift, so
.
The vertical shift is −3, so V = -3.
The sine function that represents these following conditions is
, the third one
A factor table is like this chart of numbers.
Given data:
The numbers given are 12 and 3.
The 12 and 3 are both positive integers in which 12 is greater than 3.
The 12 and 3 both lie on the right side of the number line in which 12 comes after 3, so 12 is bigger number than 3.
The 12 and 3 are both natural as well as rational number, 12 is nine more than 3.
