What is the interquartile range of 6.3, 6.4, 6.5, 6.6, 6.8, 6.8, 7.5

Hello!

First you have to find the median

6.3, 6.4, 6.5, 6.6, 6.8, 6.8, 7.5

The median is 6.6

Next you find quartile 1

quartile 1 is the median of the numbers less than 6.6

6.3, 6.4, 6.5

The median is 6.4

Next you find quartile 3

quartile 3 is the median of the numbers higher than the median

6.8, 6.8, 7.5

The median is 6.8

Then you find the range of quartile 3 and quartile 1

You subtract quartile 1 from quartile 3

6.8 - 6.4 =0.4

The interquartile range is 0.4

Hope this helps!

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

The answer is : 63explanation 60 times 0.05360+363
