Consider the population regression of log earnings (y, where y= in(earnings)l against two binary variables: whether a worker is married (d1 where d1= 1 if the person is married) and the worker's gender where(d2,where d2=1 if the person is female), and the product of the two binary variables y= β0+1d1+β2d2+β3(d1xd2) + μ. the interaction word (d1 x d2)a) allows the population effect on log earnings of being married to depend on gender b) does not make sense since it could be zero for married males c) indicates the effect of being married on log earnings d) cannot be estimated without the presence of a continuous variable

step-by-step explanation:

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
