Hi!
Let's start with the mean.
The mean is all the numbers added together, divided by how many numbers there are.
13+16+16+10+6+12+4+12+16=105
there are 9 numbers so..
105/9 = 11.7
The mean is 11.7
Find the median.
The median is the number in the middle of the data set when the numbers are in numerical order.
4, 6, 10, 12, 12, 13, 16, 16, 16
The median is 12.
Find the mode.
The mode is the number that is repeated the most.
4, 6, 10, 12, 12, 13, 16, 16, 16
The mode is 16
Find the range.
The range is the difference of the smallest number from the biggest number.
16 - 4 = 12
The range is 12
The answer is 11.7, 12, 16, 12
Hope this helps! :)
Answer:
5
Step-by-step explanation:
Angle sum property formula
(n-2)180 (where n is the number of sides)
=>(n-2)180=540
=>n-2=540/180
=>n-2=3
=>n=3+2
=>n=5
First, you make 9 into a fraction which would become 36/4
then, subtract 9/4 from both sides so that would give you 3/4x = 27/4
then divide each side by 3/4 (same thing as multiply by its reciprocal) and that would give you x=9
Justify "<span>x2 = 25 is {±5}"
First, please write x^2, not x2.
</span><span>x^2 = 25; solve for x. Take the sqrt of both sides. Must write "plus or minus " in front of the sqrt of 25:
x^2 = 25 becomes x = plus or minus 5, so x: {-5, 5}</span>
