a 75.51
b 75.23
c 74.33
d 74.67

74.67

Step-by-step explanation:

mean= sum of all data / total no. of data

= 75+79+65+77+73+79/6

= 74.66667

by rounding off,

ans is 74.67

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'.
