Answer:

option c, x = 3

Step-by-step explanation:

Given:

f(x) = 27

f(x) = $3^{x}$

Since both equal f(x) they must be equivalent as well,

$3^{x} = 27\\$

Apply exponent rule, 3 x 3 x 3 = 27

hence x = 3

Given the data set (18,14, 12, 14, 11, 11, 19, 20, 16, 11), which statements are correct?

Anuta_ua [19.1K]

The correct statement is that the <u>range of the data is 9</u>

<h3>Range of a data</h3>

The formula for calculating the range of data is expressed as:

Range = Highest value - Lowest value

From the given data

Highest value = 20
Lowest value = 11

Substituting into the formula

Range = 20 - 11

Range = 9

Hence the correct statement is that the <u>range of the data is 9</u>
