Answer: 1. 2nd endpoint (24,-18) 2. 2nd endpoint: (-19,4)
Step-by-step explanation:
1. = 7 x = 24
= -6 y= -18
2nd endpoint: (24,-18)
2. = -10 x= -19
= 2 y= 4
14.94 cm ( to 2 dec. places )
We require the sum totals of the 2 groups before calculating the mean of all 14
using mean =
Children's sum
12.6 = ( cross-multiply )
sum = 6 × 12.6 = 75.6
Adult's sum
16.7 = ( cross- multiply )
sum = 8 × 16.7 = 133.6
Total sum of all 14 = 75.6 + 133.6 = 209.2
mean = = 14.94 cm
