Answer:
x = ± 4/5
Step-by-step explanation:
25 x^2 = 16
Divide each side by 25
25 x^2 /25 = 16 /25
x^2 = 16 /25
Take the square root of each side
sqrt(x^2) = ±sqrt(16/25)
We know that sqrt(a/b) = sqrt(a)/ sqrt(b)
x = ±sqrt(16) / sqrt(25)
x = ± 4/5
In descriptive statistics, the interquartile range<span> (</span>IQR<span>), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles... ~ wikipedia
according to Wikipedia and some quick mental math the answer would be four
four is the difference between 14 and 18 which are respectively the 25th and 75th percentiles.</span><span />
Well the answer is x=2 but i’m not sure how to explain it
