Amodel that allows major league baseball player salary to differ by position isln(salary) = β0 + β1years + β2gamesyr + β3bavg + β4hrunsyr + β5rbisyr + β6runsyr +β7fldperc + β8allstar + β9frstbase + β10scndbase + β11thrdbase + β12shrtstop + β13catcher + uwhere outfield is the base group.

1. state the null hypothesis that, controlling for other factors, catchers and outfielders earn, on average, the same amount. test this hypothesis using the data in mlb1 and comment on the size of the estimated salary differential.

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
