Write the explicit formula for the arithmetic sequence.

qwelly [4]

Option C

The explicit formula for the arithmetic sequence is $a_n = 9 - 6n$

Solution:

Given that the arithmetic sequence is:

3, -3, -9, -15, -21, ...

To find: Explicit formula for the arithmetic sequence

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n - 1)d$

Where $a_n$ is nth term of sequence

n is the term's location

$a_1$ is the first term of sequence

d is the common difference between terms

In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.

In the given sequence:

3, -3, -9, -15, -21, ...

$a_1 = \text{ first term } = 3$

d = difference between any two terms in sequence

$d = a_2 - a_1$

d = -3 - (3) = -6

Substituting the values in above formula,

$a_n = 3 + (n - 1)(-6)\\\\a_n = 3 -6n + 6\\\\a_n = 9 - 6n$

Thus the explicit formula to find any term in sequence is found

Compare 9 × (11 – 4) and 3 × (11 – 4). A. 9 × (11 – 4) is three times as much as 3 × (11 – 4). B. 9 × (11 – 4) is nine times as

Hello there!

So there are two separate problems: 9 * (11-4) and 3 * (11-4). To find the value for each expression, use order of operations. We'll solve what's in the parenthesis before multiplying that value by the other number. 11-4 is 7. 7 * 9 is 63. 11-4 is 7. 7 * 3 is 21. You can divide 63 by 21 to get 3. This means that 9 * (11 - 4) is three times as much as 3 *(11 - 4). Even just by looking at the problem, the expression in the parenthesis is the same thing, but the front numbers are different. 9 is three times as much as 3. The answer is A.

Identify the type of data (qualitative/quantitative) and the level of measurement for the data described below. Explain your ch

ella [17]

Answer:

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

Step-by-step explanation:

We are given the following in the question:

"The average monthly rainfall in inches for a certain city throughout the year"

Qualitative or quantitative:

Quantitative data are measures of values or counts and are expressed as numbers.
Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. They are non-parametric values.

Thus, the given quantitative data is quantitative because rainfall is always measured and the output is expressed in numerical values.

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Level of measurement:

Ordinal: These are the qualitative variable whose order plays an important role.

Interval: When true zero does not exist. The negative values of such variables make sense.
Ratio: When true zero exist. The negative values of such variable does not make any sense.

Since,for the given data true zero exist and a negative values make no sense, thus its is ratio.

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.
