Đây ạ:

Tet is a national and family festival. It is an occasion for every Vietnamese to have a good time while thinking about the last year and the next year. At Tet, spring fairs are organized, streets and public buildings are brightly decorated and almost all shops are crowded with people shopping for Tet. At home, every is tidied, special food is cooked, offerings of food, fresh water, flowers and betel are made on the family altar with burning joss- sks scenting the air. First-footing is made when the lucky visitor comes and children are given lucky money wrapped in a red tiny envelope. Tet is also a time for peace and love. During Tet, children often behave well and friends, relatives and neighbors give each other best wishes for the new year

All of the special holiday in my country,I Tet the most.Tet is an occasion to everyone get together and warm atmosphere.Before Tet holiday,everyone prepares many things and decorates their house.I plan a lot of flower in front of my house and buy many things such as clothers and foods....

Besides,most of the streets also are decorated beautifully with colorful lights and flowers.During Tet,I spends more time on visiting my relatives,friends.Especially,I give to each other the best wishes for the new year.Tet is an opportunity for children receive lucky money.There is a funny thing that people try to avoid argument or saying any bad things at Tet.I love Tet holiday!

Trung bình cộng:

HT

hãy tìm tần số và trung bình cộng của bảng trên nhé HT

cảm ơn vì bạn đã trả lời câu hỏi của mình HT

a/b=c/d =>a/c=b/d

Áp dụng tính chất của dãy tỉ số bằng nhau ta có:

\(\frac{a}{c}=\frac{b}{d}=\frac{a+b}{c+d}\)

\(\Rightarrow\left(\frac{a}{c}\right)^2=\left(\frac{b}{d}\right)^2=\left(\frac{a+b}{c+d}\right)^2\)\(\Leftrightarrow\frac{a^2}{c^2}=\frac{b^2}{d^2}=\left(\frac{a+b}{c+d}\right)^2\)

Áp dụng tính chất của dãy tỉ số bằng nhau ta có:

\(\left(\frac{a+b}{b+d}\right)^2=\frac{a^2}{c^2}=\frac{b^2}{d^2}=\frac{a^2+b^2}{c^2+d^2}\)

\(\Rightarrow dpcm\)
