1 answer:

8 0

P(4)=(4/2)+1
=2+1
=3

p(6)=(6/2)+1
=3+1
=4

Cloud [144]

1) When it says more than, then you have to switch it so it will be 7n + 1 instead of 1+7n.
2) Because you then have to subtract by 5 you have to put the 7n + 1 in parentheses so it reads (7n + 1) - 5
3) And then to evaluate you just have to substitute n for 6
4) 7 * 6 = 42; 42+1 = 43; 43-5 = 38
5) The answer to this expression would be 38

Hope it helps :)

Answer:

The number of people would have participate in opinion poll

n = 15,267

Step-by-step explanation:

Step(i):-

Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.

Given proportion = 36% =0.36

Given the margin of error = 1% =0.01

Level of significance = 99% 0 r 0.01

Z₀.₀₁ = 2.576

step(ii):-

The margin of error of Population proportion is determined by

$M.E = \frac{Z_{0.01} \sqrt{p(1-p)} }{\sqrt{n} }$

$0.01 = \frac{2.576 \sqrt{0.36(1-0.36)} }{\sqrt{n} }$

$\sqrt{n} = \frac{2.576 \sqrt{0.36(1-0.36)} }{0.01 }$

√n = 123.648

Squaring on both sides , we get

n = 15,267

final answer:-

The number of people would have participate in opinion poll

n = 15,267
