After plotting the data from the table, with the number of times sick per year as a function of the number of apples eaten per week, I can conclude that there is no definite correlation between the two variables. This is because the data points do not have a good fit with any trend, meaning the R-squared value is low. Thus, the number of apples eaten per week has no significant effect on the number of times the people listed get sick per year.

The length of a rectangular field is 6 feet less than 5 times its width.

nordsb [41]

Answer:

5X-6)+(5X-6)+X+X=252 , now lets add all the X together, and then add the whole numbers.

12X-12=252 , now lets work this by adding 12 on each side of the equation:

12X-12+12=252+12

12X=264 , divide both sides by 12.

X=22

Now lets prove X =22:

(5·22–6)+(5·22–6)+22+22=252

(110–6)+(110–6)+22+22=252

104+104+44=252

208+44=252

252=252Therefore the length is 104 feet each and the width is 22 feet each.

Hello,

$P(x,y)=x^2+y^2-ax=0\\\\
\dfrac{\partial{P}}{\partial{x}}=2x-a\\\\
\dfrac{\partial{P}}{\partial{y}}=2y\\\\


Q(x,y)=x^2+y^2-by=0\\\\
\dfrac{\partial{Q}}{\partial{x}}=2x\\\\
\dfrac{\partial{Q}}{\partial{y}}=2y-b\\\\

\dfrac{\partial{P}}{\partial{x}}*\dfrac{\partial{Q}}{\partial{x}}+\dfrac{\partial{P}}{\partial{y}}*\dfrac{\partial{Q}}{\partial{y}}=(2x-a)*2x+2y(2y-b)\\
=4x^2+4y^2-2ax-2by\\
=2(2x^2+2y^2-ax-by)\\
=2*P(x,y)+Q(x,y))\\
=2*(0+0)=0\\\\

Answer YES
