prove \( \nabla(A \cdot B)=(A \cdot \nabla) B+(B \cdot \nabla) A+A \times(\nabla \times B)+B \times(\nabla \times A) \) where \( (A \cdot \nabla) B \) means \( A_{i} \partial_{i} B_{j} e_{j} \) in carte sian system.

Solve the equation and check the result. \[ 16 y-8(3 y-8)=-88 \] \( y=\square \)

You are given the sample mean and the population standard deviation. Use this information to construct the 90 and \( 95 \% \) confidence intervals for the population mean. Interpret the results and compare the widths of the confil intervals. From a random sample of 44 business days, the mean closing price of a certain stock was \( \$ 115.05 \). Assume the population standard deviation is \( \$ 9.77 \). The \( 90 \% \) confidence interval is \( (\square, \square) \). (Round to two decimal places as needed.) The \( 95 \% \) confidence interval is \( (\square, \square) \). (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The \( 90 \% \) confidence interval Therpret the results.
