Hello there! 6.487 rounded to the nearest hundredths place is 6.49 and 2.049 rounded to the hundredths place is 2.05. The sum of these numbers is 8.54.
Remember: If the number value after the value you are rounding is equal to or greater than 5, round up. If it is less than 5, round down.
With this in mind, let's round the numbers:
First: 6.487 rounded to the hundredths place would be 6.49, since 7 is greater than 5.
Second: 2.049 rounded to the hundredths place would be 2.05, since 9 is greater than 5.
Next, we will add the numbers together
2.05 + 6.49 = 8.54.
So, this is our final answer. I hope this answers your question & have a great day! :)
Answer:
Option 2 is correct.
Step-by-step explanation:
We have been provided a table of values of an exponential function and we are asked to find out the decay factor of the function.
Upon looking at our table we can see that every time x increases by one our y value remains one-third of the previous value.
To find out decay factor we will subtract 1/3 from 1.

Therefore, decay factor of the exponential function is
and option 2 is correct choice.
Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
302,143/2,968.7 = 101.776198336 ≈ 102 people/Sq. Mile
1. Divide the number of people by the area
2. Round to the the nearest person per Sq mile (if the number behind the number you want to round to is bigger or equal than 5 you increase the number you want to round to i. e. 2.5 ≈ 3, 2.3 ≈ 2, 1,23456 ≈ 1,235 if rounding to the third decimal point)
