- - = + 9-(-4)= 9+4 so minus minus becomes plus. and 13 is the answer.
Answer:
0,05
Step-by-step explanation:
1)First, Let’s find the mean of the data table
12 + 10 + 12 + 6 + 8 + 4 + 2 + 12 = 66
66 ÷ 8 = 8,25
2)12 - 8,25 = 3,75
10 - 8,25 = 1,25
12 - 8,25 = 3,75
6 - 8,25 = -1,75
8 - 8,25 = -0,75
4 - 8,25 = -3,75
2 - 8,25 = -5,75
12 - 8,25 = 3,75
3) 3,75 + 1,25 + 3,75 - 1,75 - 0,85 - 3,75 - 5,75 + 3,75 = 0,4
0,4 ÷ 8 = 0,05
Radius = sqrt(18) = 3*sqrt(2)
diameter = 2(3sqrt(2)) = 6sqrt(2)
<em>Answer:</em>
<em>The answer is 18k + 22p - 10</em>
<em>Step-by-step explanation:</em>
<em>That is the right answer </em>
