Answer:
The first choice, students tend to have less siblings than teachers
Step-by-step explanation:
If you look at the dot plots you notice that the teachers have more numbers than the students do and that the students have less sibling. It is not answer 2 because the students have less sibling, it is not answer 3 b/c they do not have the same range, and it is not number 4 because they do not look the same or have the same shape.
The answer is 2.8x! hope it helps
Answer:
25.7 m
Step-by-step explanation:
Hello!
We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m
We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.
- C = 2πr
- C = 2(3.14)(2.5)
- C = 5(3.14)
- C = 15.7
Now, we can add up the two lengths:
- Perimeter = straight sides + curved sides
- Perimeter = 10m + 15.7m
- Perimeter = 25.7m
Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
