An easy way to determine the slope of a roof is to set one end of a 12-inch level on the roof surface and hold it level. Then ta
ke a tape measure or ruler and measure from the other end of the level down to the roof surface. This will give you the slope of the roof.
The slope of the roof shown here is measured with a 12-inch level and a ruler.
What is the slope of the roof in this picture?

The standard error of the mean is given by:
where sigma is the standard deviation and n is the sample size. In this case the sample size is 10 and the standard deviation is 0.657, then the standard error is:
Therefore the standard error is $0.208.
<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>
Step-by-step explanation:
Here, the total number of technicians in the lab = 15
The total number of chemists in the lab = 11
So, the total members in the lab = 15 + 11 = 26
So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.
Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:
It may or may not have any technician.
It may or may not have may chemists.
So, the number of ways 5 member can randomly be chosen from a committee of 26 people =
=
Hence, there are a total 65,780 ways in which the committee can be made of 5 members.
