Put the numbers in order.
5, 8, 10, 1, 7, 6, 15, 8, 6 → 1, 5, 6, 6, 7, 8, 8, 10, 15
The median is the middle number of a data set.
1, 5, 6, 6, 7, 8, 8, 10, 15
The <u>median is 7</u>.
The lower half are the numbers before the median.
The upper half are the numbers after the median.
Lower half: 1, 5, 6, 6
Upper half: 8, 8, 10, 15

Answer:
The age of Mr. Collins is 30 years and
The model which represent the problem is, The age of Mr. Collins is 3 × 10
Step-by-step explanation:
Given as :
The age of Adam = 10 years
The age of Mr. Collins = x years
The age of Mr. Collins = 3 times the age of Adam
Or, x = 3 × The age of Adam
Or, x = 3 × 10
∴ x = 30
So, The age of Mr. Collins = x years = 30 years
The model which represent the problem is, The age of Mr. Collins = 3 × 10
Hence The age of Mr. Collins is 30 years and
Answer
6
So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:
And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:
To find the number, we just need to find x. Thus, subtract 2 from both sides:
Divide both sides by 8:
And we're done!
So, our original number was 6.
