Answer:420%
Step-by-step explanation:
It’s 420% because for already will become 400%. Then 1/5 is 20% as it is. Then 20+400 is 420 which will get you 420%.
Answer:
are you sure there isn't a 90?
Step-by-step explanation:
Because there are 4 quarters in a whole, so 22 x 4 = 88, and there are 2 quarters in 1/2 so it would be 88+2, which is 90.
Pythagorean Theorem is: a² + b² = c²
If you want to solve for "c", then you need to square root both sides
= c
Answer:
I thinks it’s 7x + 5
Step-by-step explanation:
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)
