Answer:
Step-by-step explanation:
Given
- The mean of the data set is 35 apples.
- Let's call the number of apples.
The means is defined as the quotient between the sum of all elements and the total number.
Mathematically, it would be defined as
But, we know that the mean is equal to 35.
Then, we solve for
As you can see, the total number of apples depends on the sum of all elements of the data set.
For example, if the sum of all elements is 700, the total number of apples would be
Therefore, the expression that represents the total number of apples is
Product=result of multiplication. We know that a number, we will cal “x,” times 4 = 48. Therefore:
• 1) 4x=48
• 2) 4x/4=48/4 [Division Property of Equality]
• 3) X=12
Now, we can substitute in 12 for x to check that the product is 48:
• 4) 4(12)=48
•5) 48=48 [Reflexive Property of Equality]
Answer:
Range = 30 inches
Mid Range = 55 inches
Step-by-step explanation:
Range = largest number - smallest number
70 - 40 = 30 inches
Mid range (largest number + smallest number) / 2
70 + 40 = 110 ÷ 2 = 55
