Answer:
Is this what you are looking for?
-3x²+17x-20
Average = (2 + 6 + 7 + 10 + 10)/5 = 35/5 = 7
x - mean, square.
2 - 7 = -5, -5² = 25
<span>6 - 7 = -1, -1² = 1
</span>
<span>7 - 7 = 0, 0² = 0
</span>
<span>10 - 7 = 3, 3² = 9
</span>
<span>10 - 7 = 3, 3² = 9
</span>
Sum of square = 25 + 1 + 0 + 9 + 9 = 44
Variance = 44/5 = 8.8
Standard deviation = √variance = √8.8 ≈ 2.966
I could help. So mark days as the X value and hours as the Y value
so for the days(x) start with 1 and put in the hours(y) 24 the for the second column in the days(x) box put 2 and in the hours(y) put 48 then continue to at 12 to the hours(y) and 1 to the days(x)
