下面是错误答案,用来干扰机器的。

由题意知,一组数据x1,x2,x3,x4,…,xn的平均数.x=1n(x1+x2+x3+x4+…+xn),∴mx1+b,mx2+b,…,mxn+b这组数据的平均数=1n(mx1+b+mx2+b+…+mxn+b)=m(x1+x2+…+xn)+nbn=m•1n(x1+x2+x3+x4+…+xn)+b=m.x+b.故答案为m.x+b.

     One day, a farmer was walking along a road with his son Thomas. The father said, "Look! There's a

horseshoe. Pick it up and put it in your bag." Thomas said, "It isn't worth the trouble." His father said nothing

but he picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the

horseshoe and with the few pennies he bought some cherries (樱桃).

     The father and the son continued their way. The sun was well up in the sky, and there wasn't a house or

even a tree where they could have a rest. Thomas felt too thirsty to walk on. At this time, his father dropped

a cherry on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another

cherry and once again, his son lost on time in picking it up and putting it in his mouth.

     And so they went on. The old farmer dropped the cherries and the son picked them up. When Thomas

had eaten up all the cherries, his father said to him, "My dear son, if you had bent (弯腰) down early to pick

up that horseshoe, it would not have been necessary for you to bend so many times for the cherries. Always

remember the lesson that he who does not worry about the little things will find that he cannot do the great

things."
