The ratio of females to total students in a math class is 18 to 30 what fraction and percent of the class is female

Add up 18 and 30.  You'll get 48.  Then 18/48 of the class is female.  Of course this could be simplified:  18/48 = 3/8.  Then 3/8 of the class is female and 5/8 is male.

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
