1)High blood pressure is unhealthy. Here are the results of one of the studies that link high blood pressure to death from cardiovascular disease. The researchers classified a group of white males aged 35 to 64 as having low blood pressure or high blood pressure, then followed the subjects for 5 years. The following two-way table gives the results of the study: In this example, which of the following would be appropriate to calculate? A)Conditional row percentages B)Conditional column percentages C)The correlation coefficient r d)The five-number summary of both variables 2)

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1
