Answer 1

Answer:

151 cm

Step-by-step explanation:

Mean of 6 girls (M) = 148cm (Given)

Let us assume the height of the 6th girl to be x

Mean (M) = Total sum of all heights / Total number of girls

148 = 142 + 154 + 146 + 145 + 150 + x / 6

148 = 737 + x / 6

737 + x = 148 x 6 = 888

737 + x = 888

x = 888 - 737 = 151

Thus the height of 6th girl is 151cm
