I'm guessing you're asking what shape do you get if you cut a hexagon is cut into sixths.
If this hexagon is a regular hexagon, then the shapes would be equilateral triangles.
twelve multiplied by six equals seventy two. Three multiplied by two equals six. Therefore seventy-two plus six equals seventy-eight
Answer:
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces
so
![SA=b^2+4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3Db%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have
substitute
![SA=1^2+4[\frac{1}{2}(1)(2)]](https://tex.z-dn.net/?f=SA%3D1%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%281%29%282%29%5D)
Answer:
weight of 25 students
25 × 58 = 1450kg
weight of 29 students
29 × 62 = 1798kg
total students = 25 + 29 = 54
total weight of students = 1450 + 1798 = 3248
mean weight of all students = 3248/54 = 60.19kg
The margin of error for the population mean is <span>C) 0.34. Hope that helps.</span>
