The scatter plot below shows the relationship between the percentage of American adults who smoke and years since 1945.

During this time period, the percentage of adults who smoked changed each year by about

Choose 1 answer
(A) -2 percentage points
(B) -1 percentage points
(C) -1/2 percentage points
(D) -1/4 percentage points

-1/2 percentage points.

Step-by-step explanation:

Since the data shows a mostly linear trend, a line can be drawn to estimate the rate of change.

The line approximately goes through (0,40) and (10,35), so a approximation for the slope is 35-40/10-0, equaling -1/2.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

there are 25 people coming to the party

step-by-step explanation:
