Step-by-step explanation:

7 belongs to

natural numbers  = {1,2,3,4,}

whole numbers  = {0,1,2,3}

integers  = { , -4,-3, -2 , -1 , 0 , 1 , 2 , 3 , 4 }

real numbers  include natural numbers, whole number, integers

rational numbers   include any number in p/q form

probability for j is 1/4

while

a is 1/6

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
