Which is an equation of a line that passes through the point (5,4)and is perpendicular to the line shown. start in point-slope form: ,change to slope intercept form:

you find that lines slope with points (4,1)and (0,4) so you do 4-0=4 ad 1-4=-3 so the slope is -3/4 for the line shown so the line we needs slope will be the opposite recipricole so 4/3 and to get the equation you have to plug everything in first  4=(4/3)5+b so that we can find b ( the y intercept)

4=6 2/3 +b

2 1/3=b

the equation is y=4/3+2 1/3

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
