which sampling method is the most appropriate in studying the opinions of stay-at-home mothers in all towns
across the country?

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

i belive the biggest ratio would be 18: correct me if im wrong
