Rita caught 5 fish. The lengths, in inches, of each tish are listed.
Aloiza [94]

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

\text{Range}=\text{Maximum value}-\text{Minimum value}

\text{Range}=21-9

\text{Range}=12

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.

Simplify: ³√81 - 8 ³√216 + 15 ⁴√16 + √225​
sasho [114]

Answer:

<h2>1.326 ......</h2>

Step-by-step explanation:

³√81 = 4.326

³√216 = 6

⁴√16 = 2

√225 = 15

<h3> X = ³√81 - 8 ³√216 + 15 ⁴√16 + √225 </h3>

X = 4.326 - (8×6) + (15×2) + 15

X = 4.326 - 48 + 30 + 15

X = 49.326 - 48

X = 1.326 ............
