We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.
you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So,

.Now simplify the cross off the zero from the top and the bottom to get

. So,

will give you 0.83333333333...3.

Answer:
650 kg/m³
Step-by-step explanation:
The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.
density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³
= 650 kg/m³
Hope this answer helps you :)
Have a great day
