In your problem which ask to calculate how much does it cost to operate a light for an hour is the current in a lamp is 120V and has a current of 2.4 A. The cost of electrical energy is $0.09 per kilowatt hours, so with that dat itself, the possible in terms of cents is actually 3 cents

Answer:
The probability that the man is greater than 74 inches is 0.1587
Step-by-step explanation:
The required probability is found by evaluating the area under the corresponding distribution curve for the corresponding values
The standard normal variate factor (Z) is given by
![Z=\frac{x-\bar {X}}{\sigma }](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-%5Cbar%20%7BX%7D%7D%7B%5Csigma%20%7D)
where
is mean of the data
is the standard deviation of the data
Thus corresponding to x = 74 the Z factor equals
![Z=\frac{74-70}{4}=1](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B74-70%7D%7B4%7D%3D1)
Using the standard normal distribution table corresponding to mean of 70 and deviation of 4 the area under the curve corresponding to Z = 1 equals
0.1587
Answer:
The Answer is A only (1,4)
