Answer:
Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1?
3, –6, 12, –24, 48, …
f (n + 1) = –3 f(n )
f (n + 1) = 3 f(n )
f (n + 1) = –2 f(n )
f (n + 1) = 2 f(n)
Step-by-step explanation:
0.9b + 2 is the correct answer
Using confidence interval concepts, it is found that:
The margin of error suggests Candidate Smith may receive between 45% and 51% of the votes, while Candidate Jones may receive between 47% and 53%. Because the poll estimates overlap when accounting for margin of error, the poll cannot predict the winner.
<h3>What is a confidence interval?</h3>
It is given by the <u>sample proportion plus/minus the margin of error.</u>
Then, for each candidate, the likely margins of proportion of votes are as follows:
- Candidate Smith: 45% to 51%.
- Candidate Jones: 47% to 53%.
The margin of error suggests Candidate Smith may receive between 45% and 51% of the votes, while Candidate Jones may receive between 47% and 53%. Because the poll estimates overlap when accounting for margin of error, the poll cannot predict the winner.

Answer:
To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Step-by-step explanation:
SA=2*4*5+2*4*6+2*6*5

Answer:
The side with a question mark is equal to 8
Step-by-step explanation:
The larger triangle is eight times the size of the smaller triangle. 64 divided by 8 = 8. Check with all the other side lengths, and it checks out.
