The weight average of the coordinates is -4
<h3>How to determine the 
weight average?</h3>
The complete question is given as:
The coordinate -6 has a weight of 3 and the coordinate 2 has a weight of 1. And we need to calculate the weight average
The given parameters are:
- Coordinate -6 has a weight of 3
- Coordinate 2 has a weight of 1.
The weight average is then calculated as:
Weight average = Sum of (Weigh * Coordinate)/Sum of Weights
So, we have:
Weight average = (-6 * 3 + 2 * 1)/(3 +1)
Evaluate the products
Weight average = (-18 + 2)/(3 +1)
Evaluate the sum
Weight average = -16/4
Evaluate the quotient
Weight average = -4
Hence, the weight average of the coordinates is -4

Answer:
The statement that "the margin of error was given as  percentage points" means that the population proportion is estimated to be with a certain level of confidence, within the interval
 percentage points" means that the population proportion is estimated to be with a certain level of confidence, within the interval  ; where
 ; where ![\hat{p}[tex] is the sample's proportion. The correct answer is C. The statement indicates that the interval [tex]0.14\pm0.05](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%5Btex%5D%20is%20the%20sample%27s%20proportion.%3C%2Fp%3E%3Cp%3E%20%3C%2Fp%3E%3Cp%3EThe%20correct%20answer%20is%20C.%20The%20statement%20indicates%20that%20the%20interval%20%5Btex%5D0.14%5Cpm0.05) is likely to contain the true population percentage of people that prefer chocolate pie.
 is likely to contain the true population percentage of people that prefer chocolate pie. 
Step-by-step explanation:
The margin of error for proportions is given by the following formula:

Where:
 is the critical value that corresponds to the confidence level; the confidence level being
 is the critical value that corresponds to the confidence level; the confidence level being  ,
,
 is the sample's proportion of successes,
 is the sample's proportion of successes,
 is the size of the sample.
 is the size of the sample.
In this exercise we have that  and that the margin of error is 0.05.
 and that the margin of error is 0.05. 
Therefore if we replace in the formula to calculate the confidence interval we get:

Which means that the true population proportion is estimated to be, with a certain confidence level, within the interval (0.09, 0.19).
 
        
             
        
        
        
Answer:
 approximately 
1623.6
Step-by-step explanation:
16 1/2%=.165 which is approximately equal to 1/6, so we can just multiply the original number by 6.
