Answer:
D, all the students in each grade
Step-by-step explanation:
Since the teacher wants to find out the opinion of the the entire school, they should take a random sample from each grade because it is representative of the population they want to sample. If it was just boys, it would exclude the girls, and vice versa for the girls. The teachers aren’t part of the population the teacher wants to survey, so the teacher shouldn’t survey them. Thus, that leaves the random sample from each grade.
Answer:
1) 136 m²
2) 920 ft²
Step-by-step explanation:
Prism one
Two triangles and 3 rectangles
<em>Triangles</em>
A = 1/2(6)(4)(2)
A = (6)(4)
A = 24 m²
<em>Rectangles</em>
Two rectangles; A = (2)(7)(5)
A = 70 m²
One rectangle; A = (7)(6)
A = 42 m²
Add together all the areas and get 136 m²
Prism two
Two triangles and 3 rectangles
<em>Triangles</em>
A = 1/2(15)(8)(2)
A = (15)(8)
A = 120 ft²
<em>Rectangles</em>
One rectangle; A = (17)(20)
A = 340 ft²
One rectangle; A = (20)(8)
A = 160 ft²
One rectangle; A = (20)(15)
A = 300 ft²
Add together all the areas and get 920 ft²
