anonymous · Answer

Then it should be 0.536
Correct?

anonymous · Answer

yea

anonymous · Answer

what number is the thousandth place

anonymous · Answer

The 3rd # AFTER the decimal. 
Ex: 
0.#-Tenth's
0.0#-Hundreth's
0.00#-Thousandth's
Etc...

anonymous · Answer

so in this case is the 5 right?

anonymous · Answer

In the UNROUDED answer, it is the 2nd 5. 
When you round to the THOUSANDTH'S place, you look at the number to the RIGHT of the thousandth's, and if the number is 5,6,7,8, or 9, you round up. 
In this case, since we are rounding 3 numbers after the decimal, we look at the 4th number. Since it is 0.5357 (And 7 is greater than 5) we round that 3rd number after the decimal UP. Giving you your answer of 0.536.
Got it?

based on a sample survey a company claims that a 90% of thei customers are satisfied with their products.out of 1100 customers how many would you predict to be satisfied?

anonymous · Answer

Ok, so here's what you gotta do: We're going to MULTIPLY the total amount of people by the PERCENTAGE of customers that are said to be satisfied.
Really not that hard if you know what to do.
So here it is:
1,100 X 0.90 (Because the PERCENT is 90%, we move the decimal to the LEFT 2 places.)
And your answer is: 990
