Last try 50 consider the two-way table. complete the table below to show the relative frequencies of the data in the first column. enter numbers in the boxes as decimals to the hundredth place

Alrighty then! First, lets put all focus on group 1. Group 2 is kinda irrelevant right now, but it'll be in good use soon!.
There are 36 items in category A for group 1There are 12 items in category B for group 1
Overall, there will be 48 items for group 1

We divide each one by the total A: 36/48 = 0.75B: 12/48 = 0.25
In conclusion, input the answer on top as 0.75The answer that goes in the box down below is 0.25

Hope it helps!

(4) (2x +  3)(x -  1)  =  0 is the same as 2x ^ 2 + x - 3 = 0 
when you multiply 2x   and    x it will give you 2x ^ 2 then you multiply 2x and -1 it will give -2x then multiply +3 and x that will be +3x finally multiply +3 and -1 that will be -3 
  add -2x and +3x that +1x same as +x
so you will get 2x ^ 2 + x - 3 = 0
