A measure of center<span> is a value at the </span>center<span> or middle of a </span>data set. Graphically, thecenter<span> can be viewed as the "balance point" of the display. Algebraically, the most common ways to find the </span>center<span> are with the mean, median, or mode. Mean is the average or sum of all </span>data<span> points divided by the number of points.</span>
Answer:
d. 5490
Step-by-step explanation:
Therefore, this is an arithmetic series with:
- first term (a) = 3
- common difference (d) = 3
Sum of the first n terms of an arithmetic series:
![S_n=\dfrac12n[2a+(n-1)d]](https://tex.z-dn.net/?f=S_n%3D%5Cdfrac12n%5B2a%2B%28n-1%29d%5D)
Therefore, the sum of the first 60 terms:
![\begin{aligned}S_{60} &=\dfrac12(60)[2(3)+(60-1)3]\\ & =30[6+(59)3]\\ & = 30[6+177]\\ & = 30[183]\\ & = 5490 \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DS_%7B60%7D%20%26%3D%5Cdfrac12%2860%29%5B2%283%29%2B%2860-1%293%5D%5C%5C%20%26%20%3D30%5B6%2B%2859%293%5D%5C%5C%20%26%20%3D%2030%5B6%2B177%5D%5C%5C%20%26%20%3D%2030%5B183%5D%5C%5C%20%26%20%3D%205490%20%5Cend%7Baligned%7D)
Answer: x = -9. Hope this helps, good luck! :)
Answer:
35 degrees
Step-by-step explanation:
They give you AGE is 55. AGD is a right angle, so 90-55 = 35 fr angle DGE. Since DGE and BGF are vertical angles, they are congruent.
