Researchers randomly selected participants to take part in a study. the participants were randomly assigned either a tall, thin "highball" glass or a short, wide "tumbler," each which held 355 ml. the participants were asked to pour a shot (1.5 oz. = 44.3 ml) of water into their glass.
1. did the shape of the glass make a difference in how much liquid they poured? assume all conditions for conducting inference are satisfied. use the following sample statistics to complete this problem.
statistics/drinkware tumbler highball
sample size, n 99 99
sample mean, x 60.9 ml 42.2 ml
sample standard deviation, s 17.9 ml 16.2 ml

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

If the value of cos330°is√3/2 then find cos 165°.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
