The economy of a small island nation is based on two​ sectors, coal and steel. Production of a​ dollar's worth of coal requires an input of $0.36 from coal and $.50 from steel. Production of a​ dollar's worth of steel requires an input of $0.46 from coal and $0.25 from steel. Find the output from each sector that is needed to satisfy a final demand of $34 million for coal and $73 million for steel. The output from the coal sector is approximately ​$_?

the answer is 5/3x+7/5y+7

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
