Answer:
![\sum\limits^5_{n =1} n = 15](https://tex.z-dn.net/?f=%5Csum%5Climits%5E5_%7Bn%20%3D1%7D%20%20%20n%20%3D%2015)
Step-by-step explanation:
Given
![\sum\limits^5_{n =1} n](https://tex.z-dn.net/?f=%5Csum%5Climits%5E5_%7Bn%20%3D1%7D%20%20%20n)
Required
Compute
This implies that we add n whose value ranges from 1 to 5.
So:
![Sum = 1 + 2 + 3 + 4 + 5](https://tex.z-dn.net/?f=Sum%20%3D%201%20%2B%202%20%2B%203%20%2B%204%20%2B%205)
![Sum =15](https://tex.z-dn.net/?f=Sum%20%3D15)
Hence:
![\sum\limits^5_{n =1} n = 15](https://tex.z-dn.net/?f=%5Csum%5Climits%5E5_%7Bn%20%3D1%7D%20%20%20n%20%3D%2015)
2 is 35
I’ll answer 1 in a second
D
Adding a negative is the same as subtracting
Answer:
Step-by-step explanation:
29,484
4, Does not round
the second 4, rounds to 5 because of the 8,
then The 9 would round and be 30
if its a decimal then it would be 30.0
if not then i think it would be 30,500 or 29,500 if we were to stop at the 9 and not round it
Answer: <em>-18</em>
Step-by-step explanation:
We know that Kayla’s grade was lowered every time she was late to class. Taking this into consideration, we multiply -3 and 6 (beacuse she was late to class 6 times; 3 is negative because her grade is decreasing) which results in -18.
The change is Katja’s grade is -18% or points.
