Answer:
Not geometric
Step-by-step explanation:
In a geometric sequence, each term is multiplied by a common ratio to get the next term.
So if this is a geometric sequence, then dividing each term by the one before it should result in the same common ratio.
42 / 21 = 2
126 / 42 = 3
504 / 126 = 4
The ratios are different. This is not a geometric sequence.
Answer:
Jodi must score at least 8.8 points.
Step-by-step explanation:
Step 1: Given data
Score 1 (S1): 8.9
Score 2 (S2): 7.1
Score 3 (S3): 9.2
Average (Av): 8.5
Score 4 (S4): ?
Step 2: Calculate the Score 4 so that the average is 8.5
The average is equal to the sum of the scores divided by the number of scores (4).
Av = (S1 + S2 + S3 + S4)/4
4 × Av = S1 + S2 + S3 + S4
S4 = 4 × Av - S1 - S2 - S3
S4 = 4 × 8.5 - 8.9 - 7.1 - 9.2
S4 = 8.8
Jodi must score at least 8.8 points.
The product of 3v5 and 16v5 is 18v^10
Answer:
First, we find how many red beads there are:
2 + 1 + 3 = 6
12 - 6 = 6
Red beads = 6
Now we add the red beads and the purple beads:
Purple beads = 3
Red beads = 6
3 + 6 = 9
9/12 = 3/4
Hope this helps!
