Answer:
1,539
Step-by-step explanation:
Using Simple Random Sampling in an infinite population (this is such a large population that we do not know the exact number) we have that the sample size should be the nearest integer to
where
<em>Z= the z-score corresponding to the confidence level, in this case 90%, so Z=1.645 (this means that the area under the Normal N(0,1) between [-1.645,1.645] is 90%=0.9)
</em>
<em>p= the proportion of young urban people (ages 21 to 35 years) who go to at least 3 concerts a year= 35% = 0.35
</em>
<em>q = 1-p = 0.65
</em>
<em>e = the error proportion = 2% = 0.02
</em>
Making the calculations
So, the sample size should be 1,539 young urban people (ages 21 to 35 years)
Answer:
no solution
Step-by-step explanation:
Given
- v +5 + 6v = 1 + 5v + 3 ← combine like terms on both sides
5v + 5 = 5v + 4 ( subtract 5 from both sides )
5v = 5v - 1 ( subtract 5v from both sides )
0 = - 1 ← not possible
Hence the equation has no solution
Median is the middle to find it you have to organize the list.
2, 4, 4, 5, 6, 7, 8, 8, 8.
cross them out one by one from the ends and you get 6.
your answer will be B. $6
hope this helped!

Answer:
<u>5%</u>
Step-by-step explanation
50/32= 1.56yard per second ; 50/31= 1.61 yard per second
1.61-1.56= 0.05* 100= 5%
