77julia77 [94]

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

Dmitry_Shevchenko [17]

Answer:

Elliot biked 70 miles

Explanation:

We are given that the total distance of the race is 100 miles

We are also given that Elliot covered $\frac{7}{10}$ of this distance

To get the number of miles covered by Elliot, we will simply multiply the ratio of the covered distance ( $\frac{7}{10}$ ) by thetotal distance of the race (100 miles)

This is done as follows:

Distance covered = $\frac{7}{10}$ $* 100 = 70$ miles

Therefore, Elliot biked for 70 miles

Hope this helps :)
