Consider the two-way table. group 1 group 2 category 1 30 90 category 2 14 32 complete the table below to show the relative frequencies of the data in the first row. enter numbers in the boxes as decimals to the hundredth place. group 1 group 2 category 1

im confused and i cant figure it out can someone explain how to do this

                            Group1        Group2           Total
Category 1            30                   90                120
Category 2            14                   32                  46
Total                       44                  122               166

Relative frequency:
                                   Group  1                      Group 2              Row Total
Category 1:        30/166 = 0.18             90/166 = 0.54         120/166 = 0.72
Category 2:        14/166 = 0.08             32/166 = 0.20           46/166 = 0.28
Column Total:   44/166 = 0.26           122/166 = 0.74         166/166 = 1.00

The relative frequency is the derived by dividing the amount per cell by the total balance, which is 166. It denotes the parts of the rows and columns against the whole table.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
