Answer:
(x + 5)² + (y - 4)² = 36
Step-by-step explanation:
The equation of a circle in standard form id
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 4) and r = 12 ÷ 2 = 6 , thus
(x - (- 5))² + (y - 4)² = 6², that is
(x + 5)² + (y - 4)² = 36
Answer:
The standard error of mean = 10
Step-by-step explanation:
Given a simple sample of 144 observations was taken from a large population.
The size of large sample 'n' = 144
Given sample mean and the standard deviation were determined to be 1234 and 120 respectively.
Given standard deviation of sample (S) = 120
The standard error of mean is determined by


<u>Final answer</u>:-
The standard error of mean = 10
The graphs of the inequalities given as
y > -1/4x - 5 and y > x - 2 is shown below;
Answer:
<u>J=2</u>
Step-by-step explanation:
1/2j+1=2 (Subtract 1 from both sides)
-1 -1
------------
1/2j=1
2*(1/2j)=(2)*(1) (Multiply both sides by 2)
j=2
