Answer:

Hello!
To find how much shelves we cut, we need to divide 9 feet by 3/7 feet. When dividing by fractions, it is like multiplying its reciprocal.
This means that the reciprocal of 3/7 is 7/3.
Therefore, if each shelf is 3/7 feet in length, then there are 21 shelves.
We would just double it, or multiply it by 2. .155 times 2 is set up just like regular multiplication. The answer is .310 as his batting average. Note: don't let the word "average" confuse you! Just look at the numbers in this case.
Answer:
<h3>The number is 500</h3>
Step-by-step explanation:
Let the number be x
The quotient of a number divided by five is written as
the number decreased by 400 is written as
x - 400
Equate the two expressions
We have
Multiply through by 5
That's
x = 5x - 2000
x - 5x = - 2000
- 4x = - 2000
Divide both sides by - 4
x = 500
Hope this helps you
Answer:
Step-by-step explanation:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
