The amount of bread (in hundreds pounds) x that a certain bakery is able to sell in a day is found to be a numerical value random phenomenon with probabilitydensity f(x) given byf(x)=kx for 0<=x,5=k(10-x) for 5<=x<10=0 else whereSo, find k and hence find the probability that the number of pounds of bread that will be sold tomorrow is

In a certain city, the daily consumption of electric power in millions of kilowatt-hours, is a random variable X having a gamma distribution with mean p = 15 and variance of = 75. (a) Find the values of a and B. (b) Find the probability that on any given day the daily power consumption will exceed 15 million kilowatt-hours. (a) a= 3 B = 5 (b) The probability is (Round to four decimal places as needed.)

The daily use of electricity (measured in megawatt-hours) in a certain town is a normal random variable with a mean of 18 and a standard deviation of 6. What is the probability that on a given day, the use of electricity will be between 15.6 and 19.5 megawatt-hours? Refer to the information in Problem 1. When the daily use of electricity exceeds the capacity of the power plant, a blackout occurs. If we know that the probability of a...

Lab 14 Electricity Bill Worksheet Background knowledge. The power of an electrical appliance is measured in watt (W). One watt is a measure of the energy used up in one second. The unit used for calculating power consumption is the kilowatt-hour (kWh). In order to calculate power consumed by an electrical appliance, we first convert the power to kilowatt (kW). For example, 800 W=0.8 kW, 2000 W = 2.0 kW and so on. One unit...
