Using the normal distribution, it is found that there is a 0.2776 = 27.76% probability that the life span of the monitor will be more than 20,179 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The probability that the life span of the monitor will be more than 20,179 hours is <u>one subtracted by the p-value of Z when X = 20179</u>, hence:
Z = 0.59.
Z = 0.59 has a p-value of 0.7224.
1 - 0.7224 = 0.2776.
0.2776 = 27.76% probability that the life span of the monitor will be more than 20,179 hours.

Step-by-step explanation:
I had this question a few months back and I think this was the answer not too sure though
Answer:
A. x=54 And
B. x= 89
these numbers are less then hundred.
< this sign prove that what is the less number of given question.
Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3 x - 2
Or, 3 + x - 2 -
Or, x -
or,
Now for x = - 10
Or,
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
