The ratio of boys to girls in Mrs. Kee's class is Which ratio of boys to girls is equivalent?
13
A. 34
B. 4:9
C. 4:6
D. 2:4

4:6

Step-by-step explanation:

4 to 6 boys and girls in 10 all together, making 5 boys and 5 girls in Mrs. Kee's classroom. Therefore, this is a equivalent solution to this problem do to this ratio.

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.
