a engine supplies 120 hp to an electric generator and the generator delivers 80 hp of electrical power . What is the efficiency of the generator ?
a engine supplies 120 hp to an electric generator and - 1


Answer 1
Answer: 56 mph + 89 = idont know any thing
Answer 2

Final answer:

The electric generator has an efficiency of approximately 66.67%, which means that 66.67% of the input energy is converted into usable electrical power.


The question wants to know about the efficiency of an electric generator. The efficiency of any engine or generator is defined as the ratio of useful energy output to the energy input. In this case, the energy input to the generator is 120 hp (horsepower) and the useful energy output (i.e electrical power) is 80 hp.

The formula used to calculate the efficiency is: Efficiency = (useful energy output / energy input) * 100% , Using this formula, the efficiency of the generator would be (80 / 120) * 100% = 66.67 % .

This means that 66.67% of the energy supplied to the generator is successfully converted into electrical power, while the rest is likely lost as heat or other forms of non-usable energy.

Step-by-step explanation:

The shape of the distribution of the time required to get an oil change at a 15-minute oil-change facility is unknown. However, records indicate that the mean time is 16.2 minutes, and the standard deviation is 3.4 minutes.Requried:
a. What is the probabilty that a random sample of n = 40 oil changes results in a sample mean time less than 15 minutes?
b. Suppose the manager agrees to pay each employee a​ $50 bonus if they meet a certain goal. On a typical​ Saturday, the​ oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random​ sample, there
would be a​ 10% chance of the mean​ oil-change time being at or below what​ value? This will be the goal established by the manager.



(a) Probability that a random sample of n = 45 oil changes results in a sample mean time < 10 ​minutes i=0.0001.

(b) The mean oil-change time is 15.55 minutes.

Step-by-step explanation:

Let us denote the sample mean time as x

From the Then x = mean time = 16.2 minutes

  The given standard deviation = 3.4 minutes

The value of  n sample size = 45

Firstly you must find the slope of two point

Step-by-step explanation:

m=(y2-y1)/(x2-x1) m=-8/4 = -2after this step you should choose one point. I want to choose (3,1) y-1=2*(x-3). our equation y=2x-7

Find the slope of the line that passes through the point (0,-3) and (4,5)



It depends which pair goes first but the formula is Y2-y1 over x2-x1

Answer: m=2

(0,-3) = (x1,y1)

(4,5) = (x2,y2)

Slope = (y2-y1)/(x2-x1)
