What is the common ratio of the geometric sequence below? –2, 4, –8, 16, –32, ...

SOVA2 [1]

Answer:

The common ratio of the geometric sequence is:

$r=-2$

Step-by-step explanation:

A geometric sequence has a constant ratio 'r' and is defined by

$a_n=a_1\cdot r^{n-1}$

where

aₙ is the nth term

a₁ is the first term

r is the common ratio

Given the sequence

$-2,\:4,-8,\:16,\:-32,\:...$

Compute the ratios of all the adjacent terms: $r=\frac{a_n+1}{a_n}$

$\frac{4}{-2}=-2,\:\quad \frac{-8}{4}=-2,\:\quad \frac{16}{-8}=-2,\:\quad \frac{-32}{16}=-2$

The ratio of all the adjacent terms is the same and equal to

$r=-2$

Therefore, the common ratio of the geometric sequence is:

$r=-2$

Fathi wants to print out a PDF document that is 48484848 pages long. To save paper, he decides to print on both sides of each sh

hodyreva [135]

Yes, as potatoelord said, divide 48,484,848 and 2.
48, 484, 848 ÷ 2 = 24, 242, 424.
This is because Fathi is using one paper for two pages.
Therefore, that is why you divide 48, 484, 848 and 2.

When randomly selecting an adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U

bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.

$P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

The probability of an event tells the chances of happening of that event.

It is mathematically defined as:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Complement of an event:

It is the event that consist of all outcomes not happening in A.

It is represented by $\bar{A}$

$P(A) + P(\bar{A}) = 1$

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) $P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.
