Answer:
Step-by-step explanation:
a₁ = -3 = (-1)¹×3
a₂ = 6 = (-1)²×2×3
a₃ = -28 = (-1)³×2²×7
a₄ = 72 = (-1)⁴×2³×3²
a₅ = -360 = (-1)⁵×2³×3²×5
a₆ = 2160 = (-1)⁶×2⁴×3³×5
That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.
The answer is 311/12,the decimal form is 25.916,the mixed number from is 25 11/12

<u><em>The correct answer is:</em></u>16%.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We use a z-score to answer this question.
<u>The formula for a z-score is:</u>
z=</span></span>

<span><span>,
where mue is the mean and sigma is the standard deviation.
<u>Using our information, we have:</u>
z=</span></span>

<span><span>.
Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
