Answer:

z = 1.083

z ≈ 1( that is z is approximately equals to 1)

Explanation:

from the question,

z ∝ 1/x

z = k × 1/x........................................... where k is the constant of proportionality

z = k/x

when z = 19

x = 0.68421052631579

k = ?

z = k/x

k = z × x

k = 19 × 0.68421052631579

k = 13

to find the value of z when x = 12

from

z = k/x

z 13/12

z = 1.083

z ≈ 1( that is z is approximately equals to 1)
