We look at the tens place
20 is in the tens place
now look at the Ones place
6 is in the Ones place
If it is 5 or greater we round it to the next ten, if it is 4 or less we keep it the same
6 is greater than 5
The number will be rounded to 430

Answer:
z-score = 1
Step-by-step explanation:
Given
Mean= μ=240
SD= σ=32
In order to find the z-score of a value, the mean is subtracted from the value and then divided by standard deviation.
The formula for z-score is:
z-score=(x-μ)/σ
Here x is the value whose z-score is to be found.
In the given question, x = 272
So,
z-score=(272-240)/32
=32/32
=1
So , the z-score for 272 is 1..
For example, money. If you are buying a shirt, that costs $5.49, and a pair of shoes that costs $16.99, then that would be a real world situation. You would have spent $22.48.
