Answer:
3.3 m
Step-by-step explanation:
the height = 2/3 × 5 = 10/3 = 3.3 m
In order to solve this equation, you must focus your efforts on isolating x. First, add 4x to both sides of the equation. This will eliminate it on the left and cause the equation to look like this: 35=15+4x. Next, you need to subtract 15 from both sides <span>which will eliminate it on the right and cause the equation to look like this: 20=4x. Finally, you must divide both sides of the equation by 4. Ta-da!~ This leaves you with x=5.
The answer is x=5.
Good luck and good day! c:

Answer:
Approximately 5 intervals will not capture the true mean hour of sleep freshman get at night.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean implies that there is a (1 - α) probability that the true value of the mean is included in the interval.
Or, the (1 - α)% confidence interval for the mean implies that there is (1 - α)% confidence or certainty that the true mean value is contained in the interval.
And, if 100 such (1 - α)% confidence interval for the mean are computed then 95 of these 100 interval will consist of the true mean value.
In this case it is provided that 100 researchers estimate the population mean hour of sleep freshman get at night, and each one construct a 95% confidence interval for the mean.
Then approximately 95 of these 100 confidence intervals will capture the true mean hour of sleep freshman get at night. And approximately 5 intervals will not capture the true mean hour of sleep freshman get at night.
