A boat goes 3/4 hours with a speed of 8mph and 1/3 hours with a speed of 12mph. What distance did the boat cover in all this time?

10 miles

Step-by-step explanation:

Distance d = v t

v - speed/velocity

t - time

d = (8) + (12) = 6 + 4 = 10 miles

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

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
