To find the variance, you must square the standard deviation, or <span>σ.
</span>
<span>σ = 23.9
The variance is
</span>
<span>σ²= 23.9² = 571.21

Answer: 18 is the constant rate an i don't know what to put in the x an y sorry got some <em>work of my own to do!!!</em>
Since inches are out of 12 this would be
4 ft - 1 ft = 3 ft
3' 1" - 1 " = 3 '
3 feet is also 2 ft and 12 inches
2' 12" - 9 " = 2' 3"
So the answer is 2 feet and 3 inches
Hope this helps

Answer:
Step-by-step explanation:
This is an Arithmetic Series with common difference 4 and first term 3
so the nth term an = 3 + (n -1)4
= 4n - 1.
The sum of n terms
= n/2 (a1 + L)
= n/2(3 + 1671)
= 837n.
There are (1671-3) / 4 + 1 = 418 terms in the series,
so the total value of the series is 837*418
= 349,866.
