Find the range of the following data: (a) The weights (in kg) of 10 persons are:
22, 27, 29, 31, 33, 36, 37, 39, 41, 43.

range = 21 Kg

Step-by-step explanation:

The range is the difference between the largest and smallest values in the data set

largest value = 43 Kg and smallest value = 22 Kg, thus

range = 43 - 22 = 21 Kg

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
