Wenn du von einer Zaht \( \frac{2}{5} \quad \) der Zaht subtrahierst, dann 36 addierst und das Ergebnis verdoppelst, o erhältst du 444. Welche Zaht ist gemeint?

(B) \( \lim _{x \rightarrow 2} \frac{1}{8} \cdot x-2= \)

Which of the following is a good synonym for "significant?" too large very important extremely likely

(6) \( 21-6 x=27-2 x \) (7) \( 11 x+5 x-1=65 x-36 \)

A \( 90 \% \) confidence interval for \( \mu \) is \( (11.5,12.3) \). What does \( 90 \% \) level of confidence tell us? That \( 90 \% \) of all possible \( 90 \% \) confidence intervals for \( \mu \) will actually contain the value of \( \mu \). That the probability is 0.90 that the interval \( (11.5,12.3) \) contains the value of \( \mu \). That \( 90 \% \) of the data will lie in the interval \( (11.5,12.3) \).
