5+4=6+3. You find the 6 by subtracting 3 from 9 and that is your answer:)
Answer:
{4,8,12,14}
Step-by-step explanation:
A U B={4,8,12,14}U{12,14}
={4,8,12,14}
Answer:
1
Step-by-step explanation:
4+3/3-4
3/3 = 1
4-4 = 0
1 + 0 = 1
Answer:
The answer is 1 and 4
Step-by-step explanation:
.25 x 4y = Y
36 divided by 4 = 9
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.
