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.
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
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.
j = 3 + 25
Simplifying the expression on the right side, we get:
j = 28
Therefore, j is equal to 28.
Thanks!!
You're welcome! If you have any other questions, feel free to ask.
Which of the following is always one of the data values in a data set?
A. The mean
B. The median
C. The mode
D. The range
A. The mean
B. The median
C. The mode
D. The range
B. The median is always one of the data values in a data set.
The median is the middle value of a data set when the data is arranged in order of increasing or decreasing value. Since the data set consists of actual values, the median will be one of the values in the set.
In contrast to the median, the mean (average) is the sum of all the values in the data set divided by the number of values. The mode is the value that occurs most frequently in the data set. The range is the difference between the highest and lowest values in the data set.
So, the correct option is B. The median.

Ohhh okay that was actually easy...
Yes, it is! Sometimes questions can seem difficult at first glance, but breaking them down and considering each option can help you arrive at the right answer.
The table shows Annabeth’s scores on her math assignments. Find the mean.

Enter your answer in the box.
To find the mean, we need to add up all of Annabeth's scores and divide by the total number of scores.
Total score = 89.7 + 92.6 + 83.9 + 96.2 = 362.4
Number of scores = 4
Mean = Total score / Number of scores = 362.4 / 4 = 90.6
Therefore, the mean score is 90.6.
Total score = 89.7 + 92.6 + 83.9 + 96.2 = 362.4
Number of scores = 4
Mean = Total score / Number of scores = 362.4 / 4 = 90.6
Therefore, the mean score is 90.6.
Marcos is bringing 36 cookies to his book club, but he's not sure how many people will be there. He wants to write an equation that shows how many cookies each person will get (c) in terms of how many people are there (n)
How should Marcos write his equation?
How should Marcos write his equation?
To find out how many cookies each person will get (c) in terms of how many people are there (n), we need to divide the total number of cookies (36) by the number of people (n).
So, the equation that Marcos can write is:
c = 36 / n
This equation shows that the number of cookies each person will get (c) is directly proportional to the number of people (n) present. As the number of people increases, the amount of cookies each person gets will decrease.
Make sure you specify the units of measurement for the variables, e.g., "c is the number of cookies per person" and "n is the number of people".
So, the equation that Marcos can write is:
c = 36 / n

Kwame must earn more than 16stars per day to get a prize from the classroom treasure box.
Write an inequality that describes S, the number of stars Kwame must earn per day to get a prize from the classroom treasure box.
Write an inequality that describes S, the number of stars Kwame must earn per day to get a prize from the classroom treasure box.
The inequality that describes S, the number of stars Kwame must earn per day to get a prize from the classroom treasure box, is:
S > 16
This inequality reads as "S is greater than 16". It means that Kwame must earn more than 16 stars per day in order to be eligible for the prize from the classroom treasure box.
S > 16
This inequality reads as "S is greater than 16". It means that Kwame must earn more than 16 stars per day in order to be eligible for the prize from the classroom treasure box.
