A scientist measures the growth of a bamboo plant over time. The table above shows the results. What is the best interference for the height of the plant after 45 hours?

A. 2.40 cm
B. 2.25 cm
C. 2.55 cm
D. 2.10 cm

(B) 2.25cm

Explanation:

Given:

At 40 hours, the height of the bamboo plant is 2.1cm

At 50 hours, the height of the bamboo plant is 2.4cm

Height of the bamboo plant after 45 hours = ?

The difference in length from 40 to 50 hours = 2.4 - 2.1cm

                                                                      = 0.3 cm

Mean of 40 and 50 is 45.

Thus,

At 45 hours, the height will increase by 0.3/2

                                                         = 0.15 cm

Height at 45 hour = 2.1 + 0.15cm

                           = 2.25cm

Therefore, the height of the plant after 45 hours is 2.25cm

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
