Answer:
189
Step-by-step explanation:
Since the series is geometric with common ratio r, then
r = 6 ÷ 3 = 2
The terms in the series are twice the previous term, that is the series is
3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives
sum = 189
I think it’s D I’m not sure
Answer:
The slope of the line of best fit is
⇒ 2nd option
Step-by-step explanation:
The formula of the slope of a line is
<em>To find the slope of the best line fit choose two points their positions make the number of the points over the line equal to the number of the points below the line</em>
From the attached graph points (1 , 9) and (8 , 3) are the best choice
∵ The line passes through points (1 , 9) and (8 , 3)
∴
= 1 and
= 8
∴
= 9 and
= 3
- Substitute them in the formula of the slope
∴ 
∴ The slope of the line of best fit is
I’m assuming that you only need the answer to the last one but let me know if I’m wrong :)))
I believe C would be 23.6
