E[y]=∑yp(y)=4(0.176)+(−1)(0.824) =−.12 dollar, so In one play the player is expected to lose 12% of a dollar.
Midpoint coordinates= ((x1+x2)/2 , (y1+y2)/2)
=((0+-4)/2 , ( 4+-12)/2)
= (-2, -8)
Answer:
5x-4y = -32
Step-by-step explanation:
First write the equation in point slope form
y-y1 = m(x-x1)
y - -2 = 5/4 ( x- -8)
y+2 = 5/4 (x+8)
Multiply each side by 4 to clear the fraction
4( y+2 )= 4*5/4 (x+8)
4y +8 = 5(x+8)
4y+8 = 5x+40
Subtract 4y from each side
8 = 5x-4y +40
Subtract 40 from each side
-32 = 5x-4y
5x-4y = -32
3400$-25%=2550$(remainder)
2550$*30%=765$(spent on transportation)
