The percent of adults who smoke, recorded every few years since 1967, suggests a negative linear association with no outliers. A line was fit to the data to model the relationship.
Which of these linear equations best describes the given model?
Choose 1
(Choice A)
A
y=-0.5x+40

(Choice B)
B
y=-x+40

(Choice C)
C
y=-2x+40

(Choice D)
D
y=-3x+40

Based on this equation, estimate what percent of adults smoked in 1997.
Round your answer to the nearest tenth of a percent.

the answer is a and it’s 25%

Step-by-step explanation:

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
