Answer:
22.5
Step-by-step explanation:
If you expand the series, you can see the first few terms of the series:
- Putting 1 in
, 
- Putting 2 in ,
- Putting 3 in ,
- Putting 4 in ,
We can see the series is 0, 0.5, 1, 1.5, ....
This is an arithmetic series with common difference (the difference in 2 terms) 0.5 and first term 0.
We know formula for sum of arithmetic series:
Where,
denotes the nth partial sum
is the first term (in our case it is 0)- is the term (in our case it is 10 since we want to find 10th partial sum -- sum until first 10 terms)
is the common difference (difference in term and the previous term) (in our case it is 0.5)
Substituting these into the formula, we get the 10th partial sum to be:
So the sum of the first 10 terms is 22.5. Third answer choice is right.

look it up on slader.com thats the sams problem that i have had before and it worked on slader.
The possibility Wyatt has of getting a lime chew would be 12% because his chance would be according to his experiments would be 4/33, which means that the percentage of Wyatt getting the lime chew would be 12.1212% (which the neares whole number percentage would be 12%).
Subtract 7 from 4 and Mark it on the grid, then, in order to reflect it, mark the same line in the (-,+) corner. (new coordinates are (-5,7)(-5,3)
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides
17 - 4x = y + 4x - 4x....combine like terms
17 - 4x = y...rearrange
y = -4x + 17 <===== slope intercept form
