Answer:
m<M=98
Step-by-step explanation:
(3x-16)+(x+6)+(x)= 180 *triangles equal 180*
5x-16+6=180 *combine xs*
5x-10=180 *combine variables*
5x=190 *since its -10 add 10 on both sides to isolate x*
5x/5=190/5 *divide 190 by 5 to isolate x further to get answer*
x=38 *answer for x*
-----------------------------------------------------------------------------------------------------------------<u>To find m<M</u>
3x-16
3(38)-16
98
-----------------------------------------------------------------------------------------------------------------<u>To find m<O</u>
x+6
(38)+6
44
-----------------------------------------------------------------------------------------------------------------<u>To find m<N</u>
x
(38)
38
--------------------------------------------------------------------------------------------------------------m<M=98
m<O=44
m<N=38
98+44+38=180

Part A:
Given that in a sample of 400 registered voters, 204 were democrats, i.e. n = 400, <span>
</span>The 95% confidence interval for the proportion of registered democrats voters in the population is given by:
Part B:
Given that t<span>here
are 169 million registered voters in the US, the interval for
the number of registered democrats in the population is given by
[0.461(169,000,000), 0.559(169,000,000)] = (77,909,000, 94,471,000)
