Answer:

0.8

Step-by-step explanation:

The ratio of the first two terms is ...

1.2/1.5 = 4/5 = 0.8

That is also the ratio of successive adjacent terms.

0.96/1.2 = 0.768/0.96 = 0.8

The common ratio is 0.8.

Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t

adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

$D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}$

The odd multiples of 9, $m$ , in the range $2\le m \le 82$ form the set

$\{9,27,45,63,81\}$

Each member of the set is a term of the arithmetic progression

$U_n=18n+9$

where the values of $n$ range from 0 to 4, or $0\le n\le 4$

Putting these facts together, we get the result

$D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}$

koban [17]

Answer:

$\frac{4}{55}$

Step-by-step explanation:

$\frac{2}{25} \div \frac{11}{10}$

$\frac{2}{25} \times \frac{10}{11}$

$\frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11}$

$\frac{4}{5 \times 11}$

$= \frac{4}{55}$
