The weights of professional wrestlers are approximately normally distributed with a mean of 220 pounds and a standard deviation of 7 pounds. What is the standardized score for a wrestler with a weight of 230 pounds?

C. 1.43

Step-by-step explanation:

Z score formula is x-mean/ Standard deviation

230-220/7= 10/7= 1.43

So the standardized score is 1.43

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'.
