Answer:
3x-4y
Step-by-step explanation:
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6 .
To find equivalent expressions,
distribute the first one and
factor the second one.
Given:
The graph shows the relationship between the number of pounds of apples purchased and the total cost of the apples.
To find:
The cost of 1 pound of apples.
Solution:
We need to find the slope of the line to get the cost of 1 pound of apples.
From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is
Therefore, the cost of 1 pound of apples is $1.5.
Option D : 54 is the range of the distribution
Explanation:
The given distribution is 21, 32, 49, 67, 75
The range of the distribution is the difference between the highest value and the lowest value in the distribution.
From the given data, we can see that,
Highest value = 75
Lowest value = 21
The range can be determined by subtracting by the highest value and the lowest value.
Thus, we have,
Range = Highest value - Lowest value
Range = 75 - 21
Range = 54
Thus, the range of the given distribution is 54.
Hence, Option D is the correct answer.
