C
Step-by-step explanation:
The answer for the blank is 0.003
This is the slope value, which is the number in front of the x in the least squares regression line. Each time x increases by 1, y increases by 0.003
This is the predicted y value of course.
Answer:
Sₙ = √5/2 n (n + 1)
Step-by-step explanation:
<u>Given AP:</u>
<u>Rewriting as:</u>
- √5,√4*5,√9*5,√16*5,...
- √5, 2√5, 3√5, 4√5,..., n√5
<u>Common difference:</u>
<u>Sum of n terms:</u>
- Sₙ = 1/2n (a₁ + aₙ) =
- 1/2n (√5 + √5 + (n-1)√5) =
- 1/2n (n + 1)√5=
- √5/2 n (n + 1)
Sₙ = √5/2 n (n + 1)
