The quartiles of any distribution are the values with cumulative proportions 0.25 and 0.75. the interquartile range iqr is the distance between the first and third quartiles of a distribution

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

1) letter c.

2) 4 square root of 9

hope this

step-by-step explanation:

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
