Answer:
transformers
Explanation:
A transformer is a device that increases or decreases voltage.
Answer:
velocity in problems per hour = 4 per hour
so correct option is b. 4 per hour
Explanation:
given data
worked on homework time = 1.5 hour
completed = 6 problems
to find out
What is the velocity in problems per hour
solution
we know that Shirley solve complete 6 accounting homework problem in 1.5 hour so her velocity in problems per hour will be as
velocity in problems per hour = ..................1
put here value we will get
velocity in problems per hour =
velocity in problems per hour = 4 per hour
so correct option is b. 4 per hour
Answer:
C) 20 m/s
Explanation:
Wave: A wave is a disturbance that travels through a medium and transfers energy from one point to another, without causing any permanent displacement of the medium itself. Examples of wave are, water wave, sound wave, light rays, radio waves. etc.
The velocity of a moving wave is
v = λf ............................ Equation 1
Where v = speed of the wave, λ = wave length, f = frequency of the wave.
Given: f = 2 Hz (two complete cycles in one seconds), λ = 10 meters
Substituting these values into equation 1
v = 2×10
v = 20 m/s.
Thus the speed of the wave = 20 m/s
The right option is C) 20 m/s
Answer:
- From <u>2,150 kilowatt hours</u> will qualify for the heavy user classification.
Explanation:
Since the monthly electric consumption for January follows a normal distribution, you must use a standard normal table (Z table), which provides the probabilities for the (normalized) Z-scores.
The top 6% of electric consumption, means that you must find the z-score for which the probablitiy is ≥ 0.06.
The corresponding z-score shown in the table is 1.555.
Now just use the equation:
Where:
- μ = mean = 1,650 kilowatt hours
- σ = standard deviation = 320 kilowatt hours
- x = the value of your variable, which you will determine
Substituting:
- 1.555 = (x - 1,650) / 320
- x = 320 × 1.555 + 1,650 = 2,148 ≈ 2,150
- x ≈ 2,150 kilowatt hours.
