660 students passed while 220 failed the final exam. hope this was helpful. pls give me brainliest
x=1
explaination:
2x+3=5x
Subtract 5x from both sides.
2x+3−5x=0
Combine 2x and −5x to get −3x.
−3x+3=0
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
−3x=−3
Divide both sides by −3.
x=
−3
−3
Divide −3 by −3 to get 1.
x=1

Answer:
- Mean will Increase .
- Median remains unchanged.
- Standard deviation will increase.
Step-by-step explanation:
We are given that there are 14 employees in a particular division of a company and their salaries have a mean of $70,000, a median of $55,000, and a standard deviation of $20,000.
And also the largest number on the list is $100,000 but By accident, this number is changed to $1,000,000.
Now we have to analyse the Effect of this change in data values on mean, median, and standard deviation.
- Mean will get affected because $1,000,000 is a very huge value as compared to $100,000 and is considered to be an outlier and we know that mean is affected by outliers as mean will change to $134285.7143 after replacing $100,000 with $1,000,000 .
- Median will not get affected as median the middle most value in the data set and since $1,000,000 is considered to be an outlier so median remain unchanged at $55,000 .
- Standard Deviation will also get affected as due to outlier value in the data set the numerator value will increase very much and due to which standard deviation will also increase.
