The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
<u>Interquartile Range: </u>
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
<u>Range:</u> 8 - 1 = 7
<u>Variance: </u>
We start by determining the mean,
n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.
5.3
<u>Standard Deviation</u>
We take the square root of the variance,
2.3
If you are not familiar with variance and standard deviation, just leave it.
2) Each interior angle measures 108°------> is true
3) All of the angles are congruent---------> is true
5) The sum of the measures of the interior angles is 180(5 – 2)°----> is true
That is what I got on this question but I bet it has different answers generated
Answer: she bought 5 bouquets
explanation: add the yellow and white daisies together to get 18 then do
90 ÷18=5
