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!!

Please help Fr pleased I’m begging you

Answer:

y = \frac{3}{8}x - 2

Step-by-step explanation:

<u>The answer to this problem is a simple plug-in of the given values into the slope-intercept formula.</u>

Slope intercept formula: y = mx + b

(m = slope)

(b = y intercept)

If the equation has a slope of m = \frac{3}{8}, then the slope-intercept form would be:

y = \frac{3}{8}x

If the y-intercept of an equation is (0 , -2), then the slope intercept form would be:

y = mx - 2

<u>Putting both of these values into an equation would give option A:</u>

y = \frac{3}{8}x - 2

Assoli18 [71]
<h3>Answer:  53%</h3>

===========================================================

Explanation:

The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.

Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53

Then we move the decimal to the right two spots to get 53%

Roughly 53% of the female students participate in extracurricular activities.
