Answer:
Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020 bshdggxgxgx xysfshsfsvsydvfnshdgdbdycbd dgd dh dgx dgx d
< means 'less than'. 3.5 is less than 4.5, so A is correct. Since -4.5 is NEGATIVE it is less than 0. As for C, since both numbers are negative, it would be the seemingly 'smaller' number that is actually bigger. It may help to think of the numbers on a number line. In the negatives, the numbers start to go in reverse, so the further from 0 a negative number is, the smaller it is. -4.5 IS LESS than -3.5. All answers are correct.
The answer to your question is D
Your answer is 506.44.
multiply 662 x .10 now minus that answer from 662 to get 595.80
now multiply that by .15
now minus that by 595.80
gives you 506.43
Using the normal distribution, it is found that there is a 0.1611 = 16.11% probability that the 100 pledges total more than $5,700.
<h3>Normal Probability Distribution
</h3>
In a <em>normal distribution</em> with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- For n instances of a normal variable, the mean is and the standard deviation is of
In this problem:
- Considering that each pledge is equally as likely, the mean is
- The standard deviation is .
- 100 pledges, hence .
The probability that the 100 pledges total more than $5,700 is <u>1 subtracted by the p-value of Z when X = 5700.</u>
Considering the n instances:
has a p-value of 0.8389.
1 - 0.8389 = 0.1611
0.1611 = 16.11% probability that the 100 pledges total more than $5,700.
