Arada [10]

Answer:

Nominal level of measurement

Step-by-step explanation:

The level of measurements used in this study is the nominal level of measurements. The nominal level of measurements involves the use of numbers to help classify the categories in an experiment.

In this case study, values were gotten for each categories which are brown hair, blonde hair, black hair and other hair colors. Thus, the level of measurements used is the nominal level of measurement.

Plz help! Giving away more points than usual!!! Thxs :) (btw the rate of change isn't 8 nor 29, I tried them both like 500 times
o-na [289]

Answer:

rate change: -8

Equation: y = 232 -8x

After 5 hours: 192

Step-by-step explanation:

8 are destroyed every hour, so there are 8 less every hour, so the rate of change is -8

It starts with 232 and loses 8 per hour, so the formula is

y = 232 - 8x

After 5 hours:

y = 232 - 8(5)

    y = 232 - 40

         y = 192
