SCATTER PLOT RELATIONSHIP

As the time spent training increases, the time to run 100m decreases.

Step-by-step explanation:

The scatterplot shows a negative correlation. Thus, as x increases, y decreases. Since x is training time and y is 100m time, the second option would be the appropriate response.

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'.
