Question

A plant grows at the same rate as wheat plant 2. If the plant is 4.2 cm tall, calculate how old the plant is. Use the corrected trendline for wheat plant 2.

Answer 1

The correct response is "3.127 weeks". A further explanation is given below.

Step-by-step explanation:

As we know,

y = 1.3431x

Use, y = 4.2 cm

Now,

⇒
`y = 1.3431x`

On substituting the values of y, we get

⇒
`4.2=1.3431x`

⇒
`x = (4.2)/(1.3431)`

⇒
`=3.127 \ weeks`
