Find x such that x - 4, x, and 3x - 8 are three consecutive terms in a geometric sequence

1 answer:

8 0

In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x: reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...
8 produces a sequence of 4, 8, 16 ...

Please help with the attached! Thanks!!

Kisachek [45]

Rate of change of [1,3] is $\frac{15.882-11.38}{3-1} = \frac{4.502}{2} =22.51$
Rate of change of [-4, -2] is $\frac{.0971-.0018}{-3--4} = \frac{.0953}{1}=.0953$
The difference between them is 22.51-.0953=22.4147

Hope that helps

Determine whether the following results appear to have statistical significance, and also determine whether the results have pr

MA_775_DIABLO [31]

Considering the p-value of the test, it is found that the result has neither statistical nor practical significance, as it does not give sufficient evidence that the IQ is increases by 10 to 20 points.

<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

If it is more, the null hypothesis is not rejected.

If it is less, it is rejected.

In this problem, the p-value is of 0.28, which is greater than 0.05, hence there is not enough evidence that the IQ increase is as stated, meaning that the result has neither statistical nor practical significance.

Which of the following options results in a graph that shows exponential growth?

atroni [7]

Answer:

f(x) = 0.4·3^x

Step-by-step explanation:

Exponential growth occurs when the base is greater than 1 and the exponent is an increasing non-negative function of the variable, or when the problem can be cast in that form using the rules of exponents.

Here, in f(x) = 0.4×3^x, the base is 3 (greater than 1), and the exponent of x has a positive coefficient.
