The right answer is 19.9
Step-by-step explanation:
Given data set is;
(18, 23, 17, 25, 15, 18, 18, 16, 27, 25, 18, 19)
Sum of terms = 18+23+17+25+15+18+18+16+27+25+18+19 = 239
Number of terms in data set = 12
Average = 
Average = 
Average = 19.91
The average of data set is 19.91
The right answer is 19.9

Answer:
30 degrees.
Step-by-step explanation:
We are going to use two theorems: Triangle Sum Theorem and Vertical Angles Theorem. Please let me know if you need me to define them.
Here is how I solved this problem:
75+75 = 150.
180-150 = 30(Triangle Sum theorem)
x = 30(Vertical Angles theorem.)
Answer: 8n-4
Step-by-step explanation: Should be the answer youre looking for
<span>3x^2 + 18x + 15 = 0
15 + 18x + 3x2 = 0
3(5 + 6x + x2) = 0
</span>3((5 + x)(1 + x)) = 0
5 + x = 0
5 + -5 + x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + x = 0 + -5
x = 0 + -5
x = -5
<span>--------------------------------------------
1 + x = 0
x=-1
-5,-1 </span>
4p-19
You need to distribute the 5 first then the -2
you will get 10p-15-4-6p
then all you need to do is combine like terms to get 4p-19
