Step-by-step explanation:
y=6+4x, as equation (iii)
=> -5x-(6+4x)=21
=> -5x-6-4x=21
=> -5x-4x-6=21
=> -9x-6=21
=> -9x=21+6
=> -9x=27
x= -3, by dividing both sides by -9
So, by inserting x in the first equation,
=> -4(-3)+y=6
=> 12+y=6
=> y=6-12
=> y= -6.
Therefore, x= -3 and y= -6
Answer:
The correct option is A) Confidence level
Step-by-step explanation:
Consider the provided information.
From the provided information we get the sample size is 1910 professionals
The illustration showed that 26% of them said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company. That's mean the point estimate is 26%
The margin of error was given as plus or minus 3±3 percentage points. The margin of error is the confidence interval which is plus or minus 3±3.
Now consider the provided option:
The correct option is A) Confidence level
Because from the above information we know the point estimate is 26% Sample size is 1910 and the confidence interval is 3±3.
