Answer:
b. The margin of error would decrease.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:

In which z is related to the confidence level,
is the standard deviation of the population and n is the size of the sample.
This means that the margin of error is inversely proportional to the size of the sample, which means that if the sample size increases, the margin of error decreases.
In this question, the sample size is increased, leading to a smaller margin of error. So the correct answer is given by option b.
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:


<h3>Answer: BC = 3</h3>
The answer is $10 because 123=$6 and 4 hours is =$4 6+4=10
Answer:
rectangular tables
Step-by-step explanation:
x: how many tables
a) 49x/49=800/49
x=16.3
so roughly 16 tables
b) 64x/64=800/64
x= 12.5
so roughly 12(you round to nearest even number when it is .5)
c) Now we will calcuate how many people will fit using the number of fitting capacity
=16 (8)
128
=12(12)
=144
Therefore, the rect tables will fit more people
