He data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain soccer league. construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. what percentage of players had a top speed between 1818 and 21.921.9 km/h? what percentage of players had a top speed less than 13.913.9 km/h? speed (km/hr) number of players 10 dash 13.910–13.9 44 14 dash 17.914–17.9 77 18 dash 21.918–21.9 1414 22 dash 25.922–25.9 5959 26 dash 29.926–29.9 324324 30 dash 33.930–33.9 181181 (a) construct a relative frequency distribution. speed (km/hr) relative frequency 10 dash 13.910–13.9 nothing 14 dash 17.914–17.9 nothing 18 dash 21.918–21.9 nothing 22 dash 25.922–25.9 nothing 26 dash 29.926–29.9 nothing 30 dash 33.930–33.9 nothing (round to four decimal places as needed.)

answer: a and b

step-by-step explanation:

a. she will receive a refund of $278.

step-by-step explanation:

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
