Answer:
(x+1)² + (y-4)² = 10
Step-by-step explanation:
The diameter of a circle has the endpoints at (2,3) and (-4,5).
Therefore, the length of the diameter is given by
= 2
Hence, the radius of the circle is √10.
Now the midpoint of the line joining (2,3) and (-4,5) will be the center of the straight line.
Hence, the center will be at (
Therefore the equation of the circle is
(x+1)² + (y-4)² = (√10)²
⇒ (x+1)² + (y-4)² = 10 (Answer)
Answer:
Step-by-step explanation:
Set up hypotheses as
(Left tailed test at 5% level)
Sample mean = 53.4
Sample std dev s = 4.4
Sample std error = 4.4/sqrt 50 = 0.6222
Mean diff = 3.4
Test statistic = Mean diff/std error = 0.5464
(t test only can be used as population sigma is not known)
df = 50-1 =49
p value = 0.2939
Since p>0.05 we accept null hypothesis
