A genetic experiment with peas resulted in one sample of offspring that consisted of 439 green peas and 151 yellow peas. a. Construct a \( 90 \% \) confidence interval to estimate of the percentage of yellow peas. b. Based on the confidence interval, do the results of the experiment appear to contradict the expectation that \( 25 \% \) of the offspring peas would be yellow? a. Construct a \( 90 \% \) confidence interval. Express the percentages in decimal form. \( .227

Simplify the expressions. Enter your answer in exponential form. a. \( \frac{x^{7}}{x^{9}}=\square \) b. \( \frac{t^{2}}{t^{6}}=\square \) c. \( \frac{-6}{(-6)^{4}}=\square \)

Tentukan \( A^{-1}, \operatorname{det} A \operatorname{dan} \operatorname{det} A^{-1} \) jika: \( A=\left[\begin{array}{cccc}\mathbf{2} & \mathbf{1} & \mathbf{2} & \mathbf{1} \\ \mathbf{3} & -\mathbf{3} & \mathbf{- 1} & \mathbf{4} \\ \mathbf{2} & \mathbf{3} & \mathbf{- 3} & \mathbf{1} \\ \mathbf{1} & \mathbf{4} & \mathbf{1} & \mathbf{2}\end{array}\right] \)

Divide the polynomials. The form of your answer should either be \( p(x) \) or \( p(x)+\frac{k}{x-4} \) where \( p(x) \) is a polynomial and \( k \) is an integer. \( \frac{4 x^{3}-14 x^{2}-7 x-4}{x-4}=\square \)

Write an equivalent fraction with the given denominator. \[ \frac{1}{7}=\frac{}{28} \] STEP 1: Divide the larger denominator by the smaller. \[ 28 \div 7= \] STEP \( \mathbf{2 :} \) Multiply the numerator and denominator of the given fraction by the quotier \( \frac{1 \cdot 4}{7 \cdot 4}=\frac{\square}{28} \)
