Step-by-step explanation:
Given.
The area of smaller version drawing is 
The Scale of the drawing is 2 in : 1 ft
Therefore, the area of actual picture on the wall.
So, the area of actual picture on the wall is 12 square feet.
Answer:
The mean will increase
Step-by-step explanation:
The smaller is the rounding factor, the more accurate the estimation is
532668 rounded to the nearest ten is 532670
532668 rounded to the nearest hundred is 532700
532668 rounded to the nearest thousand is 533000
532668 rounded to the nearest ten thousand is 530000
532668 rounded to the nearest hundred thousand is 500000
We can use either 532700 or 533000 as a reasonable estimate because these values don't give much difference to the original value
Using two points to find the slope use
y2-y1/x2-x1
i chose points (0,4) and (2,14)
14-4/2-0
10/2
5
The slope is 5
