5 次の英文は,家族の夜の外食行動(eating out behavior)に関する調査について述べたもので ある。英文と表を良く読み, あとの問題に答えなさい。 なお, 計算等を行う場合は、この問題の ページの余白で行うこと。 Kakeru and his friend Judy go to a university in Japan. They decided to work together to do some research about people's eating out behavior at night. They sent several questions to 300 families with children in elementary or junior high school. They asked what day of the week the families eat out at night the most and what their primary reason for eating out is. The results are shown in the tables below. Table 1 shows the days of eating out at night. According to the results of the survey, Monday is the lowest percent of all. Only one percent of the families eat out on Monday. The percent of families who eat out on Thursday is half of the percent of Wednesday. On Sunday, ten percent of families eat out. The rate of families choosing Friday or Saturday night for eating out is more than 70 percent, and Friday is higher than Saturday. Why do more families choose Friday and not Saturday for eating out? Many adults and children are on a five-day week, and Saturdays and Sundays are their days off. So, they eat out on Friday night as a reward for finishing the week's work or school. In Table 2, we can see various reasons for eating out at night, but more than 60 percent of the answers are related only to parents. Parents usually make meals for the family, and other members sometimes help to cook. As a result, when parents cannot make dinner, the family eats out. The percent of "For a change" is about half of "All family members come home too late." The research also shows that most children want to eat out more often, but about 50 percent. of parents think they eat out too much. They worry about the cost of eating at restaurants.

(1)なぜ、ウではなくエになるのかの理由を教えてほしいです 見づらくてすみません🙇‍♀️

これを読んで、あとの問いに答えなさい。 Hi, I'm Kaito. Today, I will talk about Al "devices. We use many kinds of Al devices lik use it to do work given by humans, I think Al devices can make our lives better. There "robots, "drones, and "smartphones, AI devices collect a lot of information, rememberi still a lot of work AI devices cannot do but they can do some work to make our lives easi Through my speech, I want you to learn more about Al devices and to live with them in the future. imagine how It was held by Kamome City At the event, I learned about many kinds of AI devices I didn't know anything about AI devices before I joined an event about them th that can help humans. we ca this summe 9 with her body, it asked her some questions, and gave her suggestions to make her fee better. A man from Kamome City Office said to me, Though this robot can work like doctor, (D). It cannot replace a doctor. But there will be more robots working in hospitals in the future." At the event, I started thinking about the ways to make Al device nt, I started to learn more about AI devices. I've learned that A this graph. It shows the "changes in the number of farmers in 2010, 2015, and 2020 in devices are used in many different ways. For example, AI devices help farmers. Japan and how old they were in each year. The number of farmers became smaller, and the "percentage of the farmers who were 60 years old and older than 60 years old became larger And now, AI devices are expected to be a great help to farmers. After I went to the event, 605799 Look saw graph : グラフ camera:カメラ changes in color(s): 下線部が表すグラフとして Changes in the number of farme ウ 250 (万人) 200 179.8 175.7 150 152.4 100 138.2 50 27A 2010 ° 37.5 2015 C60 years old and older than younger than 60 years old.

One robot I there helped farmers pick tomatoes. The robot has a "camera on it to collect a lot of information about the tomatoes. It remembers the shapes and "colors of "ripe tomatoes and decides when to pick the tomatoes. When it decides to pick the tomatoes, it picks them with its arms. Farmers send the tomatoes that the robot has picked to the stores. At this event, talked with a farmer who used the "tomato-picking robot. I asked him, "What do you think about working with the robot?" He said, "I don't think robots and humans can do all of the same work. But)(2). Today, robots have become very important. The number of young people who want to be farmers has become smaller, because a farmer's work is hard and needs much experience. If robots can do the hard work for farmers, they will improve farmers' lives. I hope more young people will want to become farmers." AI devices are used in our lives in many ways. I've learned that it is difficult for us to live without AI devices in today's world. However, we need to remember AI devices are not perfect. AI devices can remember all the information they collect, but 3). So, we always have to think about effective ways of using them. I hope that more AI devices will be used to help people. AI devices, like the doctor robot and the tomato-picking robot, can improve our lives. So, I want to make AI devices that can work well with humans to make our lives better in the future. That's my dream. Thank you for listening.

物理の有効数字についての質問です 力の分野の時は、有効数字について理解できていたと思っていたのですが、波の範囲に入ってから有効数字がよくわからなくなってしまいました。 有効数字のきまりを教えてくれると嬉しいです 例を挙げると222の(2)です

動 22. 気柱の共鳴 答 (1) 入 = 1.36m, f = 2.50×10Hz (2) 管内: 0.675m, 管外: 5×10-3m (3) 解説を参照 常波ができる。ピストンがjの位置にあるときに基本振動,kの位置に あるときに3倍振動がおこっている。 開口端補正があるので、波長は2 つの測定値の差から求める。 また, 管内の定常波において、節の部分は、 空気が動いておらず, 密度変化が最大の位置である。腹の部分は、空気 が激しく動いているが,密度変化がほとんどない位置である。 あう節と節の間隔は入/2であるから, 位置にあるとき, 定常波は図1のように示される。 隣り 解説 (1) 音波の波長を とする。 ピストンがj,k の 1=101.5-33.5 入=136cm=1.36m 2 4 33.5cm 振動数は, 「V=fa」の公式から. -2- f= V 340 入 1.36 =2.50×102Hz & a\m0.15000 腹 腹 32\m0.1-0.1-0.5- (2)【管内】 定常波の隣りあう節と腹の間隔は 入/4である。 図1において,管口iから管内の腹までの距離は、 l=33.5+ - =33.5+ - 4 136 4 =67.5cm=0.675m 【管外】管口付近の腹は,管口よりも少し外側にある。 求める距離を 4 とすると, 01=4- 入 -33.5 = 136 4 -33.5=0.5cm=5×10 m (3) ピストンがkの位置にあるとき, 定常波の各点にお ける変位は,縦波にもどすと図2のように示される。 j の位置は定常波の節の部分であり,媒質である空気は動 j -101.5cm 図 1 管内の腹までの距離 求めている。 管外の腹 はないので注意する。 ●管口から管の少し外 にできる腹までの距離が 開口端補正である。 疎
