Answer: 0.0944
Step-by-step explanation:
Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.
Number of cars tested do have faulty catalytic converters =42
Then the proportion of cars have faulty catalytic converters : 
Critical value of z for 99% confidence level : 
Formula for Margin of error :


Hence, the required margin of error = 
Answer:
33.3% decrease or 33%
Step-by-step explanation: 1/3 of 18 is 6. 1/3=33.3% it moved down by six people so 33% is your answer
The equation has no solution because:
5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.
I assume you want the expression to this so it would be x-y-3
