(133 + 106 + 120 + 133 + (13 - 9)) + (m + m + m) = 900
Combine Like terms
496 + 3m = 900
3m = 404
m = 404/3
If the answer doesn't seem right, just plug it in!
496 + 3(404/3) = 900
496 + 404 = 900
900 = 900
10) Same thing. The sum of the interior angles in a pentagon are 540.
(122 + 90 + 88 + 96) + k = 540
396 + k = 540
k = 144
11) The angle supplementary to the angle which measures 138 is 42. The sum of all the interior angles of a quadrilateral is 360. Let us call the missing INTERIOR angle x.
(104 + 98 + 42) + x = 360
244 + x = 360
x = 116
So the missing EXTERIOR angle is 180 - 116 which is 64.
12 is a bit confusing without showing you sorry :(

Statistics is the science of collecting, summarizing and analyzing data.
Statisticians collect and analized data, then calculate results using a specific desing. They draw conclusions and make decisions in the face of uncertainty.
-are aggregate of facts.
-must be numerically expressed.
-should be collected for a per determined purpose.
-should be collected in a systematic manner.
-should be capable of being place in relation to each other.
-are affected to a great extent by multiplicity of causes.
-are enumerated or estimated according to reasonable standards of accuracy.
By comparison, 2x = 4 and x + y = -5.
2x = 4 implies that x = 4/2 = 2
x + y = -5 implies that y = -5 - x = -5 - 2 = -7.
D. Statistics is used to answer questions with 100% certainty.
The statistics refer to the analyses, organizing, presenting, interpreting, collecting, and summarizing the data based on the mathematical models that help you to make the conclusions using the data.
Moreover, it does not give 100% certainty with respect to answering the questions but it provided you an accurate data most of the time.
There are various models like correlation, regression models through we can do the analysis.
Step-by-step explanation:statistics is not just to answer questions with certainty, statistics can be used to gather raw data and analyse them to meaningful information.it can also be used to carry out project works by analysing facts and getting a conclusion..
So statistics is never meant for 100%certainty.
