g Let $A$ be a set with 2 or more elements. We generate uniformly at random two distinct permutations of the elements of $A$. What is the probability that these permutations are the reverse of each other

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

the answer for the second equation is (4,0)

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
