A systems engineer is experimenting with a system that has traditionally produced an average quality index of 10 and a standard

deviation of 10. She is experimenting with a new method, and she will produce n outputs that are normally distributed with a new mean and the same standard deviation of 10. A standard Single Sample Z Test will be used. You would like to find a value of n such that the type I error rate is less than 5% and the type II error rate is less than 10% if the population mean of the new method is 8. Try the following values for n: 100, 200, 300, 400 and 500. Which ones meet the criteria? Which one would you choose considering that samples cost money?

Solve: 4x(x - 3)(x + 5)(2x - 7) = 0
kvasek [131]

Answer: 8x⁴ - 12x³ - 176x² + 420x

Step-by-step explanation:

First multiply 4x by (x - 3) which = 4x² - 12x. Next multiply (4x² - 12x) by (x + 5) which = 4x³ + 8x² - 60x. Multilying our new trinomial with the next binomial: (4x³ + 8x² - 60x)(2x - 7) = 8x⁴ + 16x³ - 120x² - 28x³ - 56x² + 420x. Combining like terms: 8x⁴ - 12x³ - 176x² + 420x. Notice that when you reduce and factor, you will end up with the starting binomials meaning this solution is correct.

Do you guys know what this is
Natalka [10]

Set up a proportional fraction relating RSV and RTU. Before doing that, sort out what RT is equal to;

RT =20 + 28 =48

Now, we can equate SR/SV with RT/TU. This is something we can do because they are similar, and therefore should have equal ratios between sides.

\frac{20}{3x-2} =\frac{48}{7x-3}

Cross multiply them, and solve for x.

20(7x-3)=48(3x-2)\\140x-60=144x-96\\-4x=-36\\x=9

That being said, the little cutout at the top left claims the answer is 8. If you verify my answer, it works out.
