Answer:
The mean should be 80.5. This means the average number of test scores is 80.5. The mean absolute deviation should be 15.5. This means the average of the values are less than the mean by about 15.5.
Answer:
The answer is B.
Step-by-step explanation:
To start, note that the roots of a function have to do with how many times the function passes through the x-axis.
When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).
Knowing this, you can conclude that your answer would be choice B.)3
Answer:
It takes 40 cartridges per book (B) and 30 cartridges per magazine (M) and Sarah wants to use at most 300 cartridges.
.. 40B +30M ≤ 300
It takes 200 pages to print a book and 80 pages to print a magazine and Sarah wants to use at most 1200 pages.
.. 200B +80M ≤ 1200
Hope this helped!
Answer:
1.) Subject = 18 Aquariums each with mussel
2.) Factors(levels) = temperature(3 levels) and salinity (2 levels)
3.) Treatment = High salinity high temperature ; High salinity low temperature ; High Salinity medium temperature ; Low salinity Low temperature ; Low salinity, High temperature ; Low salinity Medium temperature.
4.) Response variable = size of mussel produced
5.) Random assignment will help prevent the introduction of bias and confounding variable.
6.) For replication purpose, Each of the six treatment could be assigned to 3 tanks, so 3 aquarium for one treatment.
7.) By doing such we might be a possible location based effect which might might creep into our research. Hence, causing a spurious relationship.
8.) A control experiment whereby no salt is added will cause the mussel to die as they require salt to survive.
