7/3
Answer:
Option 3
Step-by-step explanation:
(x² + 10x + 25 - 25) + (y² - 20y + 100 - 100) + 44 = 0
(x + 5)² + (y - 10)² - 25 - 100 + 44 = 0
(x + 5)² + (y - 10)² - 81 = 0
Yes, the confidence interval provides evidence that the average has changed. The prior year’s population mean expenditure per household, $632, is not within the 95% confidence interval, (635, 663).
A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
I believe the answer to be 333
