Hope this helps but I think the mean is the average of the numbers so to find the mean you add 9,8,12,6,and 10 together and then divide by 5 because that is the total numbers you have.So that means the mean is 9. The median is the middle number of the whole set to do that first put all the numbers in order.
6,8,9,10,12 , then find the middle number.In this the middle number is 9 because either side of 9 ha the same amount of numbers (2).There are 2 numbers on the left side of 9 and there are 2 numbers on the right side of 9.
Answer:
2+2-1
Step-by-step explanation:
-44>-2x-8
Add 8 on both sides
-36>-2x
Divide by -2 dice your x can't be negative
18<x
The sign flips when you divide by a negative. Therefore if the question is a true or false question, the answer would be false

Step-by-step explanation:
Answer:
≈ 1468.59223 in squared
Step-by-step explanation:
1) A=2AB+(a+b+c)h
2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)
3) s=a+b+c / 2
4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223
≈ 1468.59223 in squared
Hope this helps :)
