The retail price of a medium-sized box of a well-known brand of cornflakes ranges from $2.24 to $2.71. assume these prices are uniformly distributed. **(round your answer to 3 decimal places.) ***(round your answer to 4 decimal places.) (a) what is the average price in this distribution? ** (b) what is the standard deviation of prices in this distribution? ** (c) if a price is randomly selected from this list, what is the probability that it will be between $2.35 and $2.44? ***

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
