if im right u add the 2 sides to get the big one
Answer:
24
Step-by-step explanation:
Average = total number of coins / number of students
If the mean number of coins with boys is 14, the total number of coins held by boys = 14 x 9 = 126
The total number of coins held by the students = total number of children x average number of coins held by the children
15 x 18 = 270
The total number of coins held by girls = 270 - 126 =144
The mean number of coins for the girls = 144 / 6 = 24
B is the rational number since 0 is a rational number and A can't be the rational number because it goes on forever.
The attachment shows work for A and B
Answer:
K' (-2, 1) L'(-2, 3) M' (-5, 3) N' (-5, 1)
So do 50 times 12 is 600. So all you have to do is divide 144 by 600 which is .24 so she already swam 24%
