Which of the following describes how circulatory and respiratory systems work together to help maintain homeostasis?

By delivering oxygen to the cells

Step-by-step explanation:

This is the answer because:

The respiratory system is responsible for moving gases into and out of the blood because it gives the bloodstream the oxygen needs. The circulatory system is responsible for moving blood to all parts of the body and transport nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen.

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.
