Due to different models and options, the fuel economy of all vehicles from a certain manufacturer are approximately normally distributed with a mean of 26.5 miles per gallon and a standard deviation of 1.9 miles per gallon. The highest 10% of all of these vehicles get fuel economy above what gas mileage

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
