Answer:
Yes
Step-by-step explanation:
It might take a while but if you just multiply a number by itself to get the perfect square it would work.
$80 x 0.19% = $15.2
$80 + $15.2 = $95.2
$110 - $95.2 = $14.80
The answer is: d. $14.80
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)
9-5=4. 4 is half the number so 4x2=8. Your number is 8.
