The average value of a random variable, with a small amount of initial information that is not combined in a statistical series, is defined as
The average value of a random variable, with a small amount of initial information that is not combined in a statistical series, is defined as + arithmetic mean; The condition of the facility in which it meets the requirements established by the technical documentation is: + performance; The condition of the product in which it is able to perform specified functions for some time (with the parameters specified in the technical documentation) is: + reliability; The consequence of a combination of adverse factors and external influences, if improperly operated, are + sudden failures; The corrosion-mechanical type of wear includes: + oxidative. The corrosion-mechanical type of wear includes: + fretting corrosion; The event of loss of performability will be called + failure; The following methods are available for measuring wear: - +Integral, micrometer; The following methods are available for measuring wear: + Integral, micrometermethod; The following factors affect the fatigue strength of parts: + A, B, C; The formula х=w1*x1+w2*x2+…+wn*xn=åwixidetermines: + weighted average; The limiting state of the parts forming the interface is determined by: + the full resource; The main characteristic of external friction is: + load on the friction surface. The maximum wear shall be determined by the following criteria: + technical and technological; The molecular-mechanical type of wear includes: + wear when seized. The measure of dispersion of individual values of a random variable relative to the average value is: + dispersion; The number of failures that have occurred over a period of time is: + random discrete quantity; The NUN plan is used to collect: + full information; The operating time from the start of operation of the facility to the onset of its ultimate state is: + full resource; The operating time of the product, upon reaching of which its operation must be stopped, regardless of the technical condition, is: + full technical resource; The operating time from the beginning to the end of operation for a non-renewable product or until repair for a renewable is: + full technical resource; The operating time of the restored product during its service life before decommissioning is: + the assigned resource; The operating time of the facility, upon reaching which the operation should be stopped regardless of the condition of the facility is: + full resource; The probability of any random event - there is a value lying on the plot: + from 0 to +1 The probability of failure-free operation of the machine P (t) under the combined action of wear and sudden failures can be determined by the theorem: + P (t) = Pw (t) * Ps (t) The ratio of the amount of depreciation to the time during which it occurs is: + wear speed. The set of values of random variables arranged in ascending order, indicating their probabilities or frequencies is: + the variation series of the distribution; The state of the object in which it is able to perform specified functions, while maintaining the basic parameters within the values established by the technical documentation is: + performability;
