Answer:

x + 4

Step-by-step explanation:

\mathrm{Factor}\:2x^2+10x+8:\quad 2\left(x^2+5x+4\right)\\=\frac{2\left(x^2+5x+4\right)}{2x+2}\\\mathrm{Factor}\:2x+2:\quad 2\left(x+1\right)\\=\frac{2\left(x^2+5x+4\right)}{2\left(x+1\right)}\\=\frac{x^2+5x+4}{\left(x+1\right)}\\\mathrm{Factor}\:x^2+5x+4:\quad \left(x+1\right)\left(x+4\right)\\\mathrm{Cancel\:the\:common\:factor:}\:x+1\\=x+4

2z - 3w = 8

Step-by-step explanation:

Where you see z you place 10 there and where you see w you place 4 there because that's the value according to the question.

So we have 2(10) - 3(4) = 20 - 12 = 8

How large a sample should be selected to provide a 95% confidence interval with a margin of error of 6? Assume that the populati
marshall27 [118]

Using the z-distribution, it is found that a sample of 171 should be selected.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

\overline{x} \pm z\frac{\sigma}{\sqrt{n}}

The margin of error is:

M = z\frac{\sigma}{\sqrt{n}}

In which:

  • \overline{x} is the sample mean.
  • z is the critical value.
  • n is the sample size.
  • \sigma is the standard deviation for the population.

For this problem, the parameters are:

z = 1.96, \sigma = 40, M = 6

Hence we solve for n to find the needed sample size.

M = z\frac{\sigma}{\sqrt{n}}

6 = 1.96\frac{40}{\sqrt{n}}

6\sqrt{n} = 40 \times 1.96

\sqrt{n} = \frac{40 \times 1.96}{6}

(\sqrt{n})^2 = \left(\frac{40 \times 1.96}{6}\right)^2

n = 170.7.

Rounding up, a sample of 171 should be selected.
