To get the equivalent fractions, you simply have to multiply the fraction with another fraction that would equal to 1.

2/8 x 2/2 (this is equal to 1) = 4/16; 1/4

3/8 x 2/2 = 6/16; 9/24

4/8 x 2/2 = 8/16; 1/2

given two terms in a geometric sequence find the 8th term and the recursive formula . a4=-12 and a5=-6
Crazy boy [7]

A geometric sequence is defined by a starting point, a, and a common ratio r

The first term is a, and you get every next term by multiplying the previous one by r.

So, our terms are

\left[\begin{array}{c|c}a_1&a\\a_2&ar\\a_3&ar^2\\a_4&ar^3=-12\\a_5&ar^4=-6\end{array}\right]

We can see that when we pass from a_4 to a_5 the number gets halved (-12 \mapsto -6)

This implies that the common ratio is r = \frac{1}{2}

So, the table becomes

\left[\begin{array}{c|c}a_1&a\\a_2&\frac{1}{2}a\\a_3&\frac{1}{4}a\\a_4&\frac{1}{8}a=-12\\a_5&\frac{1}{16}a=-6\end{array}\right]

So, we can derive the starting point from either a_4 or a_5:

\dfrac{1}{8}a = -12 \iff a = -12\cdot 8 = -96

The sequence is thus

\left[\begin{array}{c|c}a_1&-96\\a_2&-48\\a_3&-24\\a_4&-12\\a_5&-6\\a_6&-3\\\vdots&\vdots\end{array}\right]

And the recursive formula is

a_n = -\dfrac{96}{2^{n-1}}

Alex’s statement shows a previous balance of $3694.23, a payment of $100, and new transactions totaling $235. His APR is 19.2%.
Montano1993 [528]
To answer this item, first we subtract the $100 payment Alex made from the previous balance. That will give us an answer of $3,594.23. Then, we add the new transaction to the calculated value above giving us $3829.23. Multiplying the new transaction by 0.192 and adding the answer to $3829.23 will give us an answer of $3,874.35. Thus, the nearest answer is the third choice.

A company that produces light bulbs records a 1 if a light bulb is defective and a 0 if the lightbulb meets quality standards. E
storchak [24]

Answer:

B

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Probability (the 11th bulb meets quality standard) = 1/11

Probability (the next bulb will be defective) means it will not meet quality standard = 1 - 1/11 = (11 - 1)/11 = 10/11
