CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION???

Mathematics

tangare [24]3 years ago

Answer:

The complete answer is explained below.

Step-by-step explanation:

The problem is demanding to simply determine the number of years each color light would last.

We know the following information from the question:

  • As it is clear that a red light remains TURNED ON 50% of the time.
  • Green remains TURNED ON 42% of the time
  • Yellow remains TURNED ON 8% of the time.

Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

lets make conversions

As

1\:day\:=\:24\:hours  

1\:year\:=\:365\:days

Dividing 100,000 hours by 24 hours would bring 4166.67 days

Dividing 4166.67 days by 365 days would bring 11.4 years, meaning 11 years and 4 months.

Keywords: light, conversion, day, hours

Zepler [3.9K]

Answer:

1500 calories

Step-by-step explanation:

2400 is 100% of in this case, 8/8

So then we know that 1/8 of 2400 is 300 because we just divide it by 8. Sarah eats 5/8 that much so we multiply 300 by 5 which gives us 1500

VARVARA [1.3K]

Answer:

6 samples

Step-by-step explanation:

Given :

Sample size, = n

Standard deviation, = 6000

Margin of Error = 2000

Confidence interval, α = 95%

Zcritical at 95% = 1.96

n = (Zcritical * σ) / margin of error

n = (1.96 * 6000) /2000

n = 11760 / 2000

n = 5.88

n = 6 samples
