解:(1)設(shè)一季度農(nóng)民人均現(xiàn)金收入增加了x元,
由題意,得45.4%•x=44
解得x≈97(元)
答:一季度農(nóng)民人均現(xiàn)金收入增加了97元;
(2)設(shè)農(nóng)民人均生產(chǎn)經(jīng)營收入增加了x元,
由題意,得
=1-38.1%-45.4%-9.3%.
解得x≈7(元).
答:農(nóng)民人均生產(chǎn)經(jīng)營收入增加了7元;
示意圖及所占百分?jǐn)?shù),如圖:
分析:(1)由條形統(tǒng)計圖可知:出售農(nóng)產(chǎn)品收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)的45.5%.設(shè)一季度農(nóng)民人均現(xiàn)金收入增加了x元.由題意知:x•出售農(nóng)產(chǎn)品收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)=出售農(nóng)產(chǎn)品收入增加的值,列方程求解即可;
(2)生產(chǎn)經(jīng)營收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)=1-出售農(nóng)產(chǎn)品收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)-工資性收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)-生產(chǎn)經(jīng)營收入和財產(chǎn)性、轉(zhuǎn)移性現(xiàn)金收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù)=1-38.1%-45.4%-9.3%=7.2%,農(nóng)民人均生產(chǎn)經(jīng)營收入增加÷一季度農(nóng)民人均現(xiàn)金收入增加的值=生產(chǎn)經(jīng)營收入人均增長數(shù)額占一季度人均現(xiàn)金收入增長數(shù)額的百分?jǐn)?shù),即
=1-38.1%-45.4%-9.3%,解答即可.
點評:本題考查的是條形統(tǒng)計圖的綜合運用.讀懂統(tǒng)計圖,從統(tǒng)計圖中得到必要的信息是解決本題的關(guān)鍵.
