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).
The list of pairs of integers will be created by starting with the factor pairs for 30.
1 x 30
2 x 15
3 x 10
5 x 6
Then multiply these with negative integers which will result in a positive answer.
-1 x -30 (This means the opposite of one groups of negative 30, which is posiitve 30).
-2 x -15
-3 x -10
-5 x -6

Answer:
(x, y ) → (x - 14, y - 20 )
Step-by-step explanation:
A translation of 14 units to the left means subtract 14 from the original x- coordinate.
A translation of 20 units down means subtract 20 from the original y- coordinate.
The translation rule is
(x, y ) → (x - 14, y - 20 )
we are given
The pump can generate a pressure of 2.3x107 pa
so,
a radius of 0.041 m
so,
a stroke lasting 29 s, the piston moves 0.57 m
so,
Firstly, we will find area
now, we can use power formula
F=pA
W=Fh
so, W=pAh
we can plug it
now, we can plug values
now, we can simplify it
Power=2386.92414 watt.........Answer
