问题 解答题
某单位招聘员工,采取笔试与面试相结合的方式进行,两项成绩的原始分均为100分.前6名选手的得分如下:
序号
项目
123456
笔试成绩/分859284908480
面试成绩/分908886908085
根据规定,笔试成绩和面试成绩分别按一定的百分比折和成综合成绩(综合成绩的满分仍为100分)
(1)这6名选手笔试成绩的中位数是______分,众数是______分.
(2)现得知1号选手的综合成绩为88分,求笔试成绩和面试成绩个占的百分比.
(3)求出其余五名选手的综合成绩,并以综合成绩排序确定前两名人选.
答案

(1)把这组数据从小到大排列为,80,84,84,85,90,92,

最中间两个数的平均数是(84+85)÷2=84.5(分),

则这6名选手笔试成绩的中位数是84.5,

84出现了2次,出现的次数最多,

则这6名选手笔试成绩的众数是84;

故答案为:84.5,84;

(2)设笔试成绩和面试成绩各占的百分百是x,y,根据题意得:

x+y=1
85x+90y=88

解得:

x=0.4
y=0.6

笔试成绩和面试成绩各占的百分比是40%,60%;

(3)2号选手的综合成绩是92×0.4+88×0.6=89.6(分),

3号选手的综合成绩是84×0.4+86×0.6=85.2(分),

4号选手的综合成绩是90×0.4+90×0.6=90(分),

5号选手的综合成绩是84×0.4+80×0.6=81.6(分),

6号选手的综合成绩是80×0.4+85×0.6=83(分),

则综合成绩排序前两名人选是4号和2号.

We all love festivals. But since culture develops differently in many places, some festivals are, to us, very strange. Let’s take a look at some unique(独特的)festivals around the world.

Cheese Rolling Festival (England)

The festival started in the 15th century in May. When a round cheese is rolled, competitors run down the hill and try to catch it before it reaches the bottom. As the cheese can reach speeds of up to 112 km/h, it’s rare that someone catches the cheese. First to the bottom wins the cheese. But running down a very steep(陡峭的) hill behind a cheese can be dangerous. Eight people were injured in 1992.

Roswell UFO festival (New Mexico, US)

The Roswell UFO festival celebrates the anniversary(纪念日) of the “Roswell Incident”, when a UFO was said to have crashed(坠毁) nearby. Every year in July, experts, authors, researches and lecturers come to discuss the incident. The celebration also includes an alien parade, an alien costume contest, and an alien hot air balloon ride.

Hemingway Days (Florida, US)

This festival has normal stuff (材料,东西) like short-story readings and exhibits about the author. But the highlight (亮点) of the festival is definitely (一定地) the Hemingway look alike contest.

Imagine walking into a bar and being greeted by 20 middle-aged men who all look alike: stocky with thick white beards. The festival takes place in mid-July every year.
