次の英文を読み、以下の問いに答えなさい。 Cow. Chicken. Grass. Which two are in the same group? Your answer depends on where you were born and raised. T fedt af gnofed For a long time, *research psychologists have had an idea that East Asians and Westerners think about the world in different ways. There was not enough scientific *evidence to support this idea until recently. In the past 15 years, however, researchers have learned a lot about different thinking styles and the cultural differences that produce them. The story begins in 1972, when *Liang-Hwang Chiu, a professor of *educational psychology at *Indiana University, tested more than 200 Chinese and 300 American children. He showed some cards to each child. Each card had pictures of three things. One card, for example, showed a cow, a chicken, and grass. Chiu asked the children to say which two things were in the same group. Most of the American children picked the chicken and cow. They explained the reason by saying that "both are animals." Most of the Chinese children, however, put the cow and grass together because "cows eat grass." solib - People didn't think Chiu's study was very important in the years after its *publication because $*psychological scientists at that time paid little attention to cultural differences. In the 1990s, however, *cross-cultural psychology became 2"hot" and Chiu's findings were paid attention to again. 3 Researchers at the University of Michigan did Chiu's study again by testing college students from China, Taiwan, and the United States. Without using pictures, the researchers gave the students with and asked them to say which two three words shampoo, hair, and conditioner, for example 20 were in the same group. The Americans were more likely than the Chinese to say that shampoo and conditioner go together because they're both hair care goods. The Chinese were more likely to say that shampoo and hair go together because "shampoo washes and cleans hair." Why do East Asians and Westerners think differently? Most researchers believe the answer can be Taplapo 77 Step A Step B Step C

(1)の最小値の求め方の解説は理解出来たのですが、最小値が1にならない理由は何ですか。 教えてください🙇‍♀️

95 2 集合A, B を全体集合Uの部分集合として, n(U)=100, n(A)=70,n(B)=45 とすると き,次の問いに答えよ. (SES)#0080A (1) n(A∩B) の最大値、最小値を求めよ. (2) (A∩B) の最大値、最小値を求めよ. (1) n (A∩B)=x とし, n(A∩B)=a, n(A∩B)=b, (A∩B)=c とする。 n (A) >n (B) だから,xが最大となるのは, BCA すなわち, A∩B=B の場合であり, 最大値は, n(A∩B)=n(B)=45 また, n(U)=n(A∩B)+㎖ (A∩B)+m(A∩B) + n(ANB) より, 100=x+a+b+c x=100-(a+b+c) ここで, a+x=70 より, a=70-x 6+x=45 より b=45-x だから, x=100-{(70-x)+(45-x)+c} ANAYO よって, 最大値 45, 最小値 15 (2) n (A∩B)=α=70-x であり, αが最大となるのはx が最小となるとき, αが最小となるのはxが最大となる ときである. 3 よって,(1)より、合 目の包含関係すいえ 最大値 70-15=55120), 最小値 70-45=253a を求めよ。 (218の正の 05-(g onanc 46=0 のとき 02 Ca B DUAUA-5080A x=15+c 960 xが最小となるのは, cが最小となる場合であUSUA) ___n(AUB)=n(U) Sn(A)+n(B)=70+45 べて表すと つまり, c=0のときである. したがって,xの最小値は, 15 n(A)=n(ANB)+ n(ANB) ◄n(B)=n(ANB)+n(ANB) x<-1} 19 = 115>n(U) だから, n (AUB)=n(U) となる場合がある。 とするとき、ACBとなるの <考え方 (1) まず、それぞれの集合を要を書き並べて表し、2つの集合の包含関係を考える。 KEAを満たすが必ずXEB を満たすような☆の値の範囲を求める。
