Answer:
1 6 15 20 15 6 1
Step-by-step explanation:
To figure this out, we need to look at Pascal's Triangle, which is a tricky little way to find the coefficients for any binomial expression like this! Check the attached photo.
Because this is to the sixth, we need the 6th row, which is <u>1 6 15 20 15 6 1.</u> From this, we know that those numbers are the coefficients!
A is the best answer…

Answer:
The answer to
1. 22/5
2. 3
Step-by-step explanation:
First put the numbers in order least to greatest.
(1,1,2,3,4)
The mean is the average of the group of numbers.
Too find it you add all the numbers up and divide it by how many numbers there are.
In this case it would be 11 divided by 5 so the mean would be
Median is just another word for middle. After putting the numbers in order, the number in the center of the group is the median, in this case it would be 2.
The maximum would just be the largest number which is self explantory (4)
The minimum would be the lowest number (1)
I was taught to see mode as the word "most". All you do is see which number occurs the most. If all the numbers only occur once, your answer would be "No mode"
<span>It is that simple! The Range is the difference between the lowest and highest number. So all you have to do is subtract the maximum by the minimum. In this case it would be 4-1 = 3

Answer:
x = 30
Step-by-step explanation:
12 : 20 = 18 : x
⇒ 12/20 = 18/x
⇒ 12x = 18 · 20
⇒ 12x = 360
⇒ x = 360 ÷ 12
⇒ x = 30
