The margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
<h3>What is the margin of error?</h3>
The margin of error can be defined as the amount of random sampling error in the results of a survey. It is given by the formula,
= margin of error
= confidence level
= quantile
σ = standard deviation
n = sample size
As it is given that the sample size of the survey is 324, while the standard deviation of the survey is 1.6.
We know that the value of the z for 95% confidence interval is 1.96. Therefore, using the formula of the standard of error we can write it as,
Hence, the margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.

3 times 4 is equal to 12
8 times 4 is equal to 32
therefore 3:8 is equal to 12:32
hope this helps
To find the sum of the interior angles you use the formula (n-2)(180), where n is the number of sides. In this case, the number of sides is 12, so you get 1800 degrees. Then you divide by number of angles which is 12. So your answer is 150 degrees.
Answer:
OA) 14
Step-by-step explanation:
2((7+1)-1)
2(8-1)
You could expand the brackets then simplify or just simplify now. It will be better to simplify now though but I will do both methods.
Simplifying first:
2(7) = 2 × 7 = 14
Our answer is 14 So answer is OA) 14
Expanding first then simplifying:
2(8-1) = 16-2 = 14
Our answer is 14 So answer is OA) 14
