F(x)-1= 2x-1/5. replace x with 8 the answer is 3
List data in order: 20, 25, 30, 30, 31, 40, 41, 49
the IQR is the difference between Q3 and Q1
First find the median: Average the middle two numbers = 30.5
Now the median of the first half of the data = Q1 = (25 + 30)/2 = 27.5
the median of the second half of the data = Q3 = (40 + 41)/2 = 40.5
IQR = 40.5 - 27.5 = 13

Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0</h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to find equation for a circle with center (0, −4) and radius 8.
Center = (h,k) = (0, −4)
Radius = r = 8
Substituting in equation
(x-h)²+(y-k)² = r²
(x-0)²+(y-(-4))² = 8²
x²+(y+4)² = 64
x²+y²+8y+16 = 64
x²+y²+8y-48 = 0
Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0
