233.3 cubic units
Step-by-step explanation:
Volume of a pyramid
× base area × height
The volume of the pyramid
= 233.3 cubic units (rounded to the nearest tenth)
Answer:
I think it's true
Step-by-step explanation:
Answer:
An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x , 1x − 2+1x + 2=4(x − 2)(x + 2) .Set the equation to equal zero. (this ends up being √x+4−x+2=0 )
Plug this into the y= button on your TI-83/84 calculator.
Find the value of each of your solutions (go to 2nd->Calc->Value and enter your solution for x )
You should get zero as an answer for each of them.
Step-by-step explanation:
Extraneous solutions are not solutions at all. They arise from outside the problem, from the method of solution. They are extraneous because they are not solutions of the original problem. ... To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.
Answer:
Option E
Step-by-step explanation:
Single-blinding refers to a kind of clinical trial in which only the researcher conducting the study knows which treatment or the participant is receiving until the trial is over.
Control Group refers to the group in an experiment that does not receive treatment by the researchers, it is used as a benchmark to measure how the other tested subjects do.
Under the random assignment, the study participants are randomly allocated to different groups, such as the experimental group, or treatment group.
Confounding can be controlled by adjusting for it after completion of a study using stratification or multivariate analysis.
The treatment group refers to the experimental groups that receive treatment in an experiment. The “group” is made up of test subjects (people, animals, plants, cells, etc.) and the “treatment” is the variable under study.
Since here we are making groups to perform the experiment away from the main workforce, the feature used here is the treatment group.
Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
