Answer:
mean = 7 
median = 7 
range = 9 
mid range = 7.5
Step-by-step explanation:
3, 5, 6, 7, 7, 9, 12
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
12 - 3 = 9  
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
3, 5, 6, 7, 7, 9, 12
median = 7
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
(6 + 12 + 5 + 7+  7 + 3 + 9) / 7 = 7
Mid range = (highest value + lowest value) / 2
(12 + 3) / 2 = 7.5

Answer:
You can prove this statement as follows:
Step-by-step explanation:
An odd integer is a number of the form  where
 where  . Consider the following cases.
. Consider the following cases.
Case 1. If  is even we have:
 is even we have:  .
.
If we denote by  we have that
 we have that  .
.
Case 2. if  is odd we have:
 is odd we have:  .
.
If we denote by  we have that
 we have that 
This result says that the remainder when we divide the square of any odd integer by 8 is 1.
 
        
             
        
        
        
Answer:
The answer SHOULD be 7/8=224/x;256 pounds.
You may have made a mistake in inputting it here on Brainly. So look for the one that matches that. 
Step-by-step explanation:
This is what we know:
Jasper = 224 pounds
Balin = x
Jasper = 7/8 of x
Now we make an equation for that:

To match the selections we will isolate 7/8 on one side of the equation:

Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:




So x = 256 pounds
