Silvia is a member of the starting lineup of the schools basketball team. The heights of the other starting players are as followed :
170 cm , 176cm, 168cm and 148cm
The mean height of the starting lineup is 152.4 cm What is Silvia's height
Mean :
170+176+168+110 cm + S = 152.4 cm
(662 cm +S )/5 =152.4 cm
662 cm = 152.4 x 5
S= 762-662
S= 100cm
