You conduct a statistical test of hypotheses and find that the null hypothesis is statistically significant at level α = 0.05. Y

viktelen [127]

Answer:

Neither options one or two is true

Step-by-step explanation:

When we test a statistical hypothesis, we must specify a level of significance. It is this level of significance that presents the maximum probability at which we are willing to risk committing a type one error.

Therefore, it is independent of any other level of significance used.

Hence, we conclude that neither options one or two is true.

Which formula can be used to describe the sequence?

mafiozo [28]

Answer:

The formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

Step-by-step explanation:

Given : sequence -4, −24, −144,...

We have to find the formula that can be used to describe the given sequence -4, −24, −144,...

A geometric sequence is a sequence in which each higher term is multiplied by a constant number called common ratio.

Written as a, ar , ar², ar³., ....

and general term is calculated as $a_n=ar^{n-1}$

Where a is first term and r is common ratio.

Consider the given sequence -4, −24, −144,...

We find the common ratio ,

$a=-4, \\\\ar=-24,\\\\\ ar^2=-144$

Thus, common ratio is given as $r=\frac{ar}{r}=\frac{-24}{-4}=6$

Thus, the given sequence is a geometric sequence.

The general term is given by $a_n=ar^{n-1}$

Put a = -4 , r = 6

We have

$a_n=-4(6)^{n-1}$

Thus, the formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

Last one ... (w+6)^2=3(w+12)-w^2

wariber [46]

First, distribute on both sides.
w^2+6^2=3w+36-w^2
Simplify 6^2.
w^2+36=3w+36-w^2
Subtract w^2 from both sides.
36=3w+36
Subtract 36 from both sides.
0=3w
Divide both sides by 3.
0=w
