Answer:
<em>The size of the sample 'n' = 2401</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
we know that the proportion
<u><em>Step:2</em></u>
<em>The margin of error is determined by </em>
<em> </em><em></em>
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
<u>Final answer:-</u>
<em>The size of the sample 'n' = 2401 </em>
Answer:
42 out of 80
Step-by-step explanation:
Given function:
- surveys 80 people
- 42 voted
- to find the experimental probability that the next person surveyed say yes or no..
<u><em>Thinks:</em></u>
- 42 out of 80 means 42:80 in ratio form
- if 42:80 that they’ll vote for Seth Gleason then this means that the next person have 42:80 chance to vote for Seth Gleaso...
<u><em>Forms:</em></u>
- 0.525
- 42/80.. simplify form=21/40.
- 52.5%
Therefore, the percentage the next person would vote for Seth Gleason is a percentage of 52.5% and also have a ratio of 42:80.
Answer: D
Step-by-step explanation:
All would add up to 241 instead of 2.41 because you are not using decimals for the constants (Example: 25q not .25q)
Set up a proportion. (y-1)/6 = 5/3 then cross multiply to get 30 = 3y-3. add three and then divide by three to get y= 11. do the same process for X.
Domain is -
(All real numbers)
Range is -
( y belongs to R : y>5)
