The ratio of zinc to copper is 3 to 13 and a jar of the chemical contains 650 grams of copper. can you tell me the answer : d

150 grams of zinc is present

Solution:

Given that, ratio of zinc to copper is 3 to 13

A jar of the chemical contains 650 grams of copper

From given information,

zinc : copper = 3 : 13

Let the zinc present be 3x

Let the copper present be 13x

Given that, jar contains 650 grams of copper

13x = 650

x = 50

Substitute x = 50 in 3x

Zinc present = 3x = 3(50) = 150

Thus it contains 150 grams of zinc

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
