Answer:
When it is small & when the sample has things that are different from the population.
Step-by-step explanation:
A small sample has less chance of accurately reflecting a population & too many variables can also negatively influence the study.
1. (70 - 44) / 2
2. (45.00 - 25.50) / 6
3. (75 - 39) / 3
4. (90 - 30 +10) / 3
5. (100- 30+10) / 10
6. (50 - 5) / 10
PS: / means divide or division. also remember PEMDAS
Hope this helped you (;
Anwser is 10cm bc you multiply 10amd 3 then divided it
I believe it would be 4
This is because when divided by 3, 3x+12y=3 turns into x+4y=3
It would be (all under a big square root) (-7-5)squared + (3+2) squared. This equals to about root 169
