laila [671]

Answer

C. 49, 17, 4, 18

Step by step explanation

Here mean of all the data set is 88

To find the most spread of data, we need to find the range.

range of set A = The highest value - the lowest value = 36-6 = 30

Range of set B = 30-15 = 15

Range of set C = 49-4 = 45

Range of set D = 30-14= 16

Here the highest range is in Set C.

Therefore, answer is C. 49, 17, 4, 18

Which expression is equivalent to (x Superscript 27 Baseline y) Superscript one-third?
alexgriva [62]

Answer:

x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)

OR x^9/(∛y)

Step-by-step explanation:

Given the indicinal equation

(x^27/y)^1/3

To find the corresponding expression, we will simplify the equation as shown:

(x^27/y)^⅓

= (x^27)^⅓/y⅓

= {x^(3×9)}^⅓/y⅓

= x^9/y⅓

= x^9/(∛y)

The right answer is x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)
