Answer:

D. Amount of income earned and years of education

Step-by-step explanation:

A positive correlation is a linear movement where when one variable increases, another variable increases as well.

Shoe size and weight have correlation.
Day of the week and temperature also have no correlation.
Cost to heat a house and putside temperature would be a negative correlation because on variable is decreasing while the other is increasing.
The longer your education, the more your income will make because of your knowledge on that particular subject.

Therefore, the best answer is D.

hope this helps!

love history [14]

Answer:

The 3 friends ate 1/5 of the pie.

Step-by-step explanation:

The total of this pie is 5/5 so if Josh and his brother ate 4/5 of the pie that means that there was 1/5 pie left so that is what the 3 friends ate.

Eighteen boys joined a group of p students in the auditorium. If the ratio of boys to girls was then 5:4 write and algebraic exp

ycow [4]

Answer: The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Number of boys added: 18
Ratio of boys to girls: 5:4

So, the total number of boys is:

x + 18

Number of girls = y

Number of boys / number of girls = 5/4

(x+18) /y = 5/4

Solving for "y"

4 (x +18) =5 y

4x +72 = 5y

(4x +72) /5 = y

The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5

Find the volume of the largest rectangular box in the first octant with three faces in the coordinate planes and one vertex in t

makkiz [27]

Answer:

Step-by-step explanation:

$x + 2y + 3z = 12$

$z=\frac{12-x-2y}{3}$

Volume = $V=f(x,y) = xy(\frac{12-x-2y}{3} )$

find partial derivatives using product rule

$f_x =\frac{y}{3} (12-2x-2y)\\f_y = \frac{x}{3} (12-x-4y)$

i.e.

Using maximum for partial derivatives, we equate first partial derivative to 0.

y=0 or x+y =6

x=0 or x+4y =12

Simplify to get y =2, x = 4

thus critical points are (4,2) (6,0) (0,3)

Of these D the II derivative test gives

D<0 only for (4,2)

Hence maximum volume is when x=4, y=2, z= 4/3

Max volume is = 4(2)(4/3) = 32/3
