Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So since you are too lazy I assume that you already know what to do and you just don't want to do it so I don't think you'll need any explaining right?
X: -5 -1 0 1

Y: -32 -8 -2 4
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.

Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5
