To find relative frequency of no voters;
p(A)=favourable outcomes/total outcomes
p(A)=100/400
= 1/4 or 0.25
Therefore, the probability a person will respond with a no is 0.25.
Hope I helped :)
-1^3 - -1^2 +1= -1. ...........
It's pretty simple if you just read through it carefully. Here you go.
7x-15=-2
Move -15 to the rigjt side,
7x=-2+15
7x=13
Divide both sides by 7,
7x/7=13/7
x=13/7
