Step-by-step explanation:

mean=5.5

standard dev=2.85

Within 1 standard dev = 5.5-2.85 to 5.5+2.85 = 2.65 to 8.35

Within 2 standard dev = 5.5-2(2.85) to 5.5+2(2.85) = -0.2 to 11.2

Within 3 standard dev = 5.5-3(2.85) to 5.5+3(2.85) = -3.05 to 14.05

How do u solve this equation?
Mnenie [13.5K]

Answer:

x^3+4x^2+3x-4 R 9

Step-by-step explanation:

There are two ways to solve polynomial division problems, long division, and synthesis. Synthesis won't work because the divisor is not in ax+c form, where a is always 1, and c is any integer. So, long division must be used. I would work it out here, but that would take for ever, so I provided a link to a website that shows you how to solve this.

Hope this helps! :)
