Josh created a pattern by using tiles. Twenty tiles were blue. For the rest of the pattern he used equal numbers of red white ti

Ber [7]

Answer: The number of red tiles = 15.

Step-by-step explanation:

Let the number of red tiles be x, and the total tiles be y.

Since, the pattern he used equal numbers of red white tiles, therefore the number of white tiles = x

The number of blue tiles = 20

Forty percent of the pattern was made of blue tiles and 40%=0.40

Therefore,

$0.40y=20\\\Rightarrow\ y=\frac{20}{0.4}\\\Rightarrow\ y=50$

Now, the total number of tiles = $x+x+20=50$

$\Rightarrow\ 2x=50-20\\\Rigjhtarrow\ x=30\\\Rightarrow\ x=15$

The number of red tiles = 15.

The interquartile range of the data is equal to 2.18.

<h3>What is an interquartile range?</h3>

The interquartile range is a measure of where a data set's "middle fifty" is located. Whereas a range is a measure of where the start and end of a set are, an interquartile range is a measure of where the majority of the values are.

Given data is { 1.56,1.77,2.22,2.35,2.45,2.77,3.26,4.35,5.23,6.02}.

The upper limit is, and the median is 2.22.

{ 1.56,1.77,<u>2.22</u>,2.35,2.45,2.77}

The lower limit is, and the median is 4.35.

{2.77,3.26,<u>4.35</u>,5.23,6.02}

The interquartile range will be calculated as,

IQR = 4.35 - 2.22

IQR = 2.18
