Answer:
observational study
Step-by-step explanation:
This situation calls for an observational study. Unfortunately, cardiovascular health is difficult to measure unless one defines some "health scale" so that health could be roughly quantitized.
Answer:
you simply think of a number that when multiplied by itself it will give you that whole number
Step-by-step explanation:
let's take for instance the number 4 it's a whole number and still a perfect square because when you think of a number from 1to 10, which number when you multiply by itself will give you four apart from 2
When you round, if the number you are rounding is more than 0, it will never be rounded down to 0. So 6.63 can never be rounded to 6.60 since 3 is more than 0.
In order to round the hundredths, you need to look at the thousandths.
The thousandths in 6.633 is the second 3.
Since 3 is less than 5, the first 3 will remain the same.
The correct answer is 6.63
hope this helps =)
