Question

The scatterplot shows data for the area of Pacific sea ice between $2000$ and $2012$. The best fit line is shown in the graph and the equation of the line is $A\left(t\right)=-0.187t+380.5,$ where $A\left(t\right)$ represents the area of measurable sea ice in the Pacific Ocean in the year t. Find the area of Pacific sea ice in the year $2020$?

• A. $2.76$
• B. $2.25$
• C. $3.76$
• D. $1.86$

Answer 1

The correct option is A $2.76$

A(t) = -0.187t + 380.5
Given, t = 2020
$A\left(2020\right)=-0.187\left(2020\right)+380.5=2.76$
