rational number is any number that can be written as the
ratio between two other numbers i.e. in the form
Part A:
An easy choice that makes sense is 7.8, right in the middle. To prove that it's rational we need to write it as a ratio. In this case we have
Part B:
We need a number that can't be written as a ratio (because it neither terminates nor repeats). Some common ones are
,
,
and
so it makes sense to try and use those to build our number. In this case
works nicely.
Answer:
Step-by-step explanation:
In order to find who is more efficient at planting carrots, we want to put both ratios in terms of the same amount of time.
For simplicity, lets see how many carrots each can make in 1 hour.
Janet can plant 36 feet of carrots in one hour
Amy can plant 34 feet of carrots in one hour
So, Janet can plant carrots more quickly
Answer:
y= -3/4x+2
Step-by-step explanation:
3x+4y=8
-3x -3x
----------------
4y=-3x+8
Divided by 4 on each sides
y= -3/4x+2
Answer + step-by-step explanation:
7/10 as a decimal would be 0.7.
7/10 or 0.7 in a word form would be seven tenths.

To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.
