Answers:
1: y = 1x + 0.5
3: the y-intercept shows that the original data began above 0 and has had a steady increase since. (not sure abt this one)
4: I'm sorry i don't know this one
5: the data collection shows that the height to arm span has a ratio of 1 throughout you can tell this by using the line of best fit.
6: according to the line of best fit the height of the person will also be about 66 inches.
7: according to the line of best fit the arm span will also be about 74 inches.
X equals to 48
The work is shown in the picture. I hope this helps.
Answer:
B. Perimeter of a square and
C. Side length of a square
Step-by-step explanation:
if n= side length of square then
- Area of square is

- Perimeter of a square is 4×n
- diagonal length of a square is
× n
Thus,
Perimeter of square can be expressed as
×diagonal length of a square
Side length of a square can be expressed as
×diagonal length of a square
but Area of square is
×n×diagonal length of a square
As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
