Answer: 3 step by step approach
Step-by-step explanation:
Since the Chancellor has to use a multi-stage sample to carry out the survey, he or she should carry it out step by step.
First, he or she should randomly sample some solar systems from the galaxy, then secondly sample planets within that solar system, and finally randomly sample countries within the selected planets
Answer:
The volume of the steps is:
Step-by-step explanation:
Remember that the volume regularly is:
- Volume = height * width * depth.
There are many forms to solve this exercise, but I'll show you two:
1. Imagine that aren't steps but a big solid, then its volume would be:
- Volume of big solid = 60 cm * 60 cm * 120 cm
- Volume of big solid = 432000 cm3
Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (<em>where is the blank for the step</em>):
- Volume of a small solid = 30 cm * 30 cm * 120 cm
- Volume of a small solid = 108000 cm3
Now you subtract:
- Volume of the building steps = 432000 cm3 - 108000 cm3
- <u>Volume of the building steps = 324000 cm3
</u>
2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:
- Volume of the building steps = 3 (30 cm * 30 cm * 120 cm)
- <u>Volume of the building steps = 324000 cm3</u>
Answer:
i'm not sure but i think it might be this answer?
if it isn't then x = 4 and y = 4
Sorry if my answers are wrong
