1)For the situation, show the work for the four steps to solving the inverse variation problem. The graph of a function passes through the point (50,3.6), and y varies inversely as x. Find the value of y when x is 75.

A) Calculate the value of k=xy.

B) Write the equation that represents the inverse variation function.

C) Substitute the given value into the function equation and solve to determine the corresponding quantity.

D) Check your solutions by subtracting both quantities back into k=xy.

Arandomized controlled trial is designed to evaluate the effect of metoprolol in patients with heart failure. while preparing for statistical analysis, the researcher reviews some common types of statistical errors. which of the following statements is true regarding a type i error in a clinical study? a. the study is not significantly powered to detect a true difference between study groups. bthe null hypothesis is true but is rejected in error. c. the null hypothesis is false but is accepted in error. d. type i error is also known as beta and is usually 0.1 or 0.2. e. type i error depends on the study's confidence interval.
