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
Answer:
-9/10
Step-by-step explanation:
when dividing fractions, the second fraction flips upside down. Then you just multiply.
-4/5 divided by 8/9 becomes -4/5 * 9/8 = -36/40 = -9/10
Answer:
The confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample mean is 
The standard deviation is 
The sample size is 
given that the confidence level is 85% then the level of significance is mathematically represented as

Next we obtain the critical value of
from the normal distribution table the value is

Generally the margin of error is mathematically represented as

=> 
=> 
The 85% confidence interval is mathematically represented as

=> 
=> 
I may be wrong but I think it is "True"
