Answer:

option B

Step-by-step explanation:

The level of measurement describes the nature of the information assigned to variables within the values.

If the interval is meaningful but the ratio is not, then we can say that the data is an interval level of measurement.

If interval and ratio are meaningful then we can say that data is at the ratio level of measurement.

Ordinal level of measurement is the method of ranking system. Like in the given statement woman tried to rank the nail polish.

Hence, the correct answer is option B

If a lineman can install 12 insulators in 183/4 hours, how many insulators should he be able to install in 281/8 hours?
katrin2010 [14]

Answer: 9

Step-by-step explanation:

12 insulators = 183/4 hours

x = 281/8

x × 183/4 = 12 ×281/ 8

183x/4 = 6 × 281/4

183x / 4 = 1686 / 4

4 cancel out 4

183x = 1686

Divide bothside by 183

x = 1686/183

x= 9.21311

x = 9 approximately.

Coffee with sugar and milk added to it can contain up to calories. To consume a maximum of 600 mg if caffeine per day, how many
Marina CMI [18]
We know there is 330 mg of caffeine per 16-ounce serving. So if we want 8-ounce servings:
330 mg : 2 = 165 mg
Also we have to consume a maximum of 600 mg.
165 mg * 3 = 495 mg < 600 mg
165 mg * 4 = 660 mg > 600 mg
Answer: Someone could drink 3 full 8-ounce servings in a day and still stay below the limit.
