The least-squares regression model y=-3.4 +5.2z and correlation coefficient r 0.66 were calculated for a set of bivariate data with variables a and y Vhich of the following is closest to the proportion of the variation in y that cannot be explained by the explanatory varisble?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
