we know that

<u>The correlation coefficient </u>is a number between -1 and +1 that represent the linear dependence of two variables or sets of data

Let

A(1,4)\ B(2,1.5)\ C(3,3)\ D(4,4)\ E(5,2)

Using the function CORREL in a Excel tool

Find the correlation coefficient for the set of data

see the attached table

the correlation coefficient is  r=-0.20801

therefore

<u>the answer is the option B</u>

-0.21

At the end of tomorrow, inventory of 5+20 pallets will have been used to fill orders for 2+10 pallets. That leaves inventory on hand of

... 25 - 12 = 13 pallets

Since each holds 20 panels, that amounts to

you want to find out how many pens and pencils you cn buy with that 90$ so you want to do

.75y+.15x=90

pens=50

pencils=50

but you want to add .75+.15 which = .90

then you divide 90/.90

and that equals 100

then split it up and each gets 50

One end of a 4ft iron rod is attached to the center of a pulley with radius of 0.5 ft. The other end is attached at a 40 degree
mr_godi [17]
We use the formula
L = rθ
where s is the arc length or the length of the wire
r is the distance from the center to the end of the rod
θ is the angle made by the rod with the wall

Substituting the values and converting the angle to radian measure
L = 4 (40°) (π/180°)
L = 2.79 feet<span />
