The answer is 14 weeks
<span>60 + 30w = 480
30w = 480 - 60
30w = 420
w = 420 / 30
w = 14</span>
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
<h3>How to find a constant of proportionality in direct proportional equation</h3>
Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of <em>direct</em> proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:
k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.

Answer:
Option 1.
(I don't really have any explanation to add on)
Answer: 0.29 (29%)
Step-by-step explanation:
women who gave birth at a certain hospital last year:
over 30 years old - 0.48
unmarried - 0.46
over 30 or unmarried (or both) - 0.65
what is the probability that a woman who gave birth at the hospital was both unmarried and over 30 ?
We know that
P(A and B) = P(A) + P(B) - P(A or B)
P(+30 and unmarried) = P(+30) + P(unmarried) - P(+30 or unmarried)
P(+30 and unmarried) = 0.48 + 0.46 - 0.65 = 0.29
