You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.
Answer:
Step-by-step explanation:
A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
Hello!
The goal of this to isolate the variable and solve for the given variable which is "t".
8t+3=27=2t
First you subtract three from both sides.
8t+3=27=2t
-3 -3
8t=24=2t
Next subtract 2t from both sides.
8t=24=2t
-2t -2t
6t = 24
now isolate the variable by dividing 6 on both sides
6t = 24
/6 /6
t = 4
