5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying

5x + 8 = ?

If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8

45 + 8 = 53

Therefore 5x + 8 = 53

Hope this helps you! :)

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

<em> $X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$ </em>

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

<em> $X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$ </em>

<em> $X^2 = = 35.159$ </em>
