Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
The general term for the sequence is n+2.
Answer:
Wow, I'm learning this in class right now lol, the answer is C, 42cm cubed.
Step-by-step explanation:
The formula for finding volume fo 3d shapes is area of base x height/length.
In this problem, they give you both of those. 14 x 3 = 42, so the answer is C.
Hope this helped! If it did, please give me brainliest! It would help a lot! Thanks! :D
Answer:
14.7 (Because you asked for no units)
Step-by-step explanation:
The volume of this triangular prism is 1/2 BHL
0.5 * 3.5 * 2 * 4.2 = 14.7 ft^3
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
