Which number can be added to the data so that the range of the data will be 55?
56, 81, 54, 47, 45, 94
A. 49
B. 98
C. 39
D. 6
Choose 1 answer:
B. 98
How come??
To find the range, we need to subtract the lowest value from the highest value in the given data.
Highest value = 94
Lowest value = 45
Range = highest value - lowest value
Range = 94 - 45
Range = 49
Since the current range is 49, we need to find a number that, when added to the data, will make the range equal to 55.
Let's call the number we need to find "x".
Range after adding "x" = 55
So, we can write an equation as follows:
94 + x - 45 = 55
Simplifying the equation, we get:
x = 55 - 49
Therefore,
x = 6
So, we need to add 6 to the data to get the desired range.
Checking:
New highest value = 94 + 6 = 100
New lowest value = 45
New range = 100 - 45 = 55
Thus, Option D is incorrect and B is the correct answer.
Ah.. okay thanks!!
You're welcome! Let me know if you have any other questions.
Write an equation to represent the following statement.
j is 25 more than 3.
Solve for j
The equation to represent the given statement is:
j = 3 + 25
Simplifying the expression on the right side, we get:
j = 28
Therefore, j is equal to 28.
Thanks!!
