Is it true that Confidence intervals are always close to their true population values?

Mathematics
1 answer:
user100 [1]3 years ago
6 0

Answer:

This means that there is a 95% probability that the confidence interval will contain the true population mean. Thus, P( [sample mean] - margin of error < μ < [sample mean] + margin of error) = 0.95.

Simplify. 2x(-11x - 7)
Anettt [7]

Answer:

The answer is -22x² - 14x.

Step-by-step explanation:

You have to eliminate the brackets by multiplying :

2x( - 11x - 7)

= 2x( - 11x) + 2x( - 7)

=  - 22 {x}^{2}  - 14x

Next you can simplify but there is no common terms in this expression so it remains the same.
