Joanna recorded the number of laps she swam during practice in one week. freestyle 100 breaststroke 50 backstroke 60 butterfly 25 what is the value of the breaststroke to butterfly ratio? [type your answer as a fraction in simplest form. use / for the fraction bar and no spaces.]

50\25

simplest form 2\1

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
