-20^3=-8000, so the real cube root of -8000 is -20.
Step-by-step explanation:
equate the two equations
Answer:

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
Answer:
IQR= (16)−(10)=6
Thus, option 'C' is true.
Step-by-step explanation:
Given the data
8, 9, 9, 10, 12, 12, 13, 14, 15, 15, 15, 16, 18, 19, 20
The interquartile range is equal to the difference between the 75th and the 25th percentiles
The 25th percentile is 10
The 75th percentile is 16
Finally,
IQR= (16)−(10)=6
Thus, option 'C' is true.
