What is the interquartile range of this set of data? 15, 19, 20, 25, 31, 38, 41

1 answer:

8 0

First, you have to find the median, which is the number in the middle: 25

Then cut the data in half by the median, so your new data sets are
15,29,20
and
31,38,41

Now you find the median of both of those sets, which is 29 and 38.

The interquartile range is the difference between the numbers, so 38-29 = 9.

Suppose you are doing a binary search of the list [15, 18, 2, 19, 18, 0, 8, 14, 19, 14]. How many comparisons would you need to

Illusion [34]

Answer:

Three Times.

Step-by-step explanation:

First and foremost a binary search requires that the array be sorted in ascending or descending order.

After the initial step the search goes to the middle most value

i.e. $[0, 2,8,14,14,15,18,18,19,19]$

will be the second 14, which is the first iteration.

Since 14 is less than 19 the search will eliminate the lower half of the including 14, and will iterate again through the array:

$[15,18,18,19,19]$

The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. $[19,19]$ .

The search will run once i.e. third iteration, and will return key value found.

goblinko [34]

The range that the amount withheld vary if the weekly wages, after subtracting withholding allowances, vary from $600 to $700 inclusive is: 76.35<x<101.35.

<h3>Range</h3>

Given

592<x1317

74.35+.25

Hence:

Lowest range

74.35+.25(600-592)

74.35+.25(8)

74.35+2

=76.35

Highest range

74.35+.25(700-592)

74.35+.25(108)

74.35+27

=101.35

Range

76.35<x<101.35

Therefore the range that the amount withheld vary if the weekly wages, after subtracting withholding allowances, vary from $600 to $700 inclusive is: 76.35<x<101.35.

How to simplify radicals into simplest radical form?

liraira [26]

An example should help :-

Simplify sqrt 20:-

sqrt 20 = sqrt (4 * 5) = sqrt 4 * sqrt5 = 2 sqrt5

cube root of 54 = cube root 27 * cube root 2 = 3 cube root 2

The rule is to factor the number and look for perfect squares or cubes, etc.
