Find the range and the midrange for the following data set: 7.25, 6.75, 6, 7.5, 7, 7, 7, 7.5, 6, 8.5, 8.5, 6.5, 7, 5.5, 8.5, 7.25, 7.25 a Range = 7.25, Midrange = 6.25 b Range = 3, Midrange = 7 c Range = 5.75, Midrange = 6.5 d Range = 8, Midrange = 7.25

B

Step-by-step explanation:

The min and max numbers are 5.5 and 8.5. To find range, you subtract the bigger number by the smaller number. To find midrange, you find the median of the 2 min and max numbers.

8.5-5.5=3

5.5 6 6.5 7 7.5 8 8.5

 1   2  3   4  5   6   7

So the range is 3 and the midrange is 7.

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
