In a class of 32 students, The mean height of the 14 boys is 1.56 metres The mean height of all 32 students are 1.515 metres Work out the mean height of the girls.

48.48 m is the answer

Step-by-step explanation:

the number of girls in the class = 32 - 14 = 18 girls.

sum of the boy's heights = 14 * 1.56 = 21.84 m.

sum of all the student's heights = 32 * 1.515 = 48.48 m.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
