Answer:
8483 ft²
Step-by-step explanation:
Subtract the area of the smaller circle from the area of the greater circle
Greater Circle area:
πr² = π × 140²
= 61583.2 ft²
Smaller Circle area:
= π × 130²
= 53099.8 ft²
Area of track:
61583.2 - 53099.8 = 8483.4ft²
= 8483ft² (to the nearest ft²)
Answer:
Step-by-step explanation:
The slope represents how much y is predicted to change on average for each 1 unit in x.
y = appraised value of a house in East Meadow County
x = # of rooms
1 unit of x = 1 additional room
1 unit of y = $1,000
slope = 19.79
Answer: Each additional room in a house in East Meadow County is predicted to increase the appraised value by 19.79 x $1,000 = $19,790, on average.
Note: Since we only sampled homes in East Meadow County, our regression equation is only good to predict appraised values in that county. So, our interpretation must include that fact.
