Thickness measurements of a coating process are made to the nearest hundredth of a millimeter. The thickness measurements are uniformly distributed with values 0.14, 0.15, 0.16, 0.17, 0.18. Determine the mean and variance of the coating thickness for this process. Round your answers to four decimal places (e. g. 98.7654).

We can calculate the sample variance with the following formula:

And replacing we got:

And the deviation is given by this:

If we want to find the population deviation we just need to use this formula:

And replacing we got:

And the population deviation would be:

Step-by-step explanation:

For this case we have the following values:

0.14, 0.15, 0.16, 0.17, 0.18.

We can calculate the mean with the following formula:

And replacing we got:

We can calculate the sample variance with the following formula:

And replacing we got:

And the deviation is given by this:

If we want to find the population deviation we just need to use this formula:

And replacing we got:

And the population deviation would be:

x = 25/2304

step-by-step explanation:

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
