The value of x is -3.5
Because dividing both sides by -2.4 is going to get you a value of -3.5. And a negative divided by a negative is a positive. :D
I think the definition of your sequence is u(n) = 3n - 2 .
That little set of parentheses makes it SO much
easier to read and understand.
To find u(any number) just write the number in place of 'n' .
u(27) = 3(27) - 2
= 81 - 2
= 79 .

Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:
So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
