Assuming that you’re asking for a fraction of 0.31 where 31 repeats?
31/99
Answer:
105°
Step-by-step explanation:
The Arc DB = 150°,
If an angle goes from the center of the circle it is the same as the arc. If the angle is inscribed in the circle it is half the arc.
In this case A is inscribed in the circle so its value is half the arc,
The arc is 360 - 150 = 210°
Angle A = 210 / 2 = 105°
Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=

Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
(1)
x² + y² = 196 ← is in this form
with centre = (0, 0 ) and r = = 14
(2)
x² + y² = 100 ← is in this form
with centre = (0, 0 ) and r = = 10
