In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
            sunny   snowy
Male:       17      11
Female:   15      16

Add the rows up. 
            sunny   snowy       total
Male:       17      11              28
Female:   15      16             31

Then divide the number the by the total:   
            sunny           snowy       total
Male:       17/28        11/28              28
Female:   15/31        16/31             31      

Yours says to round to the 1000th place, so it ends up like:
            sunny   snowy     
Male:       .607      .393     
Female:    .484      .515
 
 Hope that helps!!

Vijay has a collection of 50 number cubes that are each 1 cubic inch. He finds a box that is 4 inches high.He fits 12 cubes into
Lera25 [3.4K]

No, Vijay cannot fit all cubes into the box.

Solution:

Total number of cubes = 50

Volume of each cube = 1 cubic inch

Number of cubes fit in the bottom of the box = 12

Area of the box<em> = l</em> × <em>b</em> = 12 square inch

Height of the box = 4 inch

Volume of the box = <em> l</em> × <em>b </em>× h

                               = 12 × 4

Volume of the box = 48 cubic inch

So, 48 cubes can only fit in the box.

Hence, Vijay cannot fit 50 cubes into the box.

qwelly [4]
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
                ____________________________________
                                          Total Numbers
15 = 3 + 19 + 8 + 32 + x
       ______________
                      5
Cross Multiply
___________
3 + 19 + 8 + 32 +  = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
