N is an odd integer

The Next Larger is N+2

N+2 + 2N = -27 + 4N

3N + 2 = 4N - 27

0 = 4N - 27 - 3N - 2

0 = N - 29

N = 29

They are 29 and 31.

31 + 2(29) = 4(29) - 27

31 + 58 = 89 = 116 - 27  yes it works

A research firm conducts a sample survey and discovers that 90% of people are more afraid of snakes than they are of flying. If
nikitadnepr [17]

Answer:

Different values of margin of error for different significance level.

Step-by-step explanation:

We are given the following in the question:

p =  90% = 0.9

Sample size, n  790

We have to find the margin of error.

Formula:

z_{stat}\sqrt{\dfrac{p(1-p)}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

ME = \pm 1.96\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME = \pm 0.021

z_{critical}\text{ at}~\alpha_{0.10} = 1.64

ME = \pm 1.64\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME =\pm 0.018

z_{critical}\text{ at}~\alpha_{0.10} = 2.58

ME =\pm 2.58\sqrt{\dfrac{0.9(1-0.9)}{790}}\\\\ME =\pm 0.028

15=7x+1-5x


Put like terms together. ( group anything alike)

15+1=16

7x-5x=2x

16 2x
—- ——-
2x 2x


2x/2x cancels itself out.

16 divided by 2 is 8

x=8

I hope this helped!
