What are your thoughts on the loss of trees? Explain. (At least 4 sentences long).
kipiarov [429]

Answer: My thoughts on the loss of trees is quite disappointing due to the fact that we need them to survive. The loss of trees is not something good for the environment because many animals need it for shelters. It could cause animals to be endangered because they can’t hide from predators or hunters. Hopefully the trees will start increasing in 2020.

99% of all confidence intervals with a 99% confidence level should contain the population parameter of interest. true or false
tester [92]

The statement that 99% of all confidence intervals with a 99% confidence level should contain the population parameter of interest is false.

A confidence interval (CI) is essentially a range of estimates for an unknown parameter in frequentist statistics. The most frequent confidence level is 95%, but other levels, such 90% or 99%, are infrequently used for generating confidence intervals.

The confidence level is a measurement of the proportion of long-term associated CIs that include the parameter's true value. This is closely related to the moment-based estimate approach.

In a straightforward illustration, when the population mean is the quantity that needs to be estimated, the sample mean is a straightforward estimate. The population variance can also be calculated using the sample variance. Using the sample mean and the true mean's probability.

Hence we can generally infer that the given statement is false.

10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35

In triangle ABC, (angle A) is a right angle and (m angle B) = 45deg.
Ratling [72]
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to x \sqrt{2}, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to 16 \sqrt{2} ft
