Answer:
- The mean length of 10 children's big finger is 8.1 cm
Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.
- The mean length of 11 adult's big finger is 14.1 cm
Average length of all the 11 adult's big finger is (14.1×11) cm =155.1
- Mean length of these 21 people's big finger is

- Hence, <em><u>11.24</u></em> is the right answer.
Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
I chose x^3, it would be a cubic function , then it’s -(x-6 )^3 -2
for the volume do the equation length×width×height. so 10×4×2.75
Answer:
The answer is -x+12/ x (x-2)
