A study published in Health Magazine in 2010 suggested that a combination of high blood pressure and binge drinking have an increased risk of having a stroke or heart attack. As part of a study that followed 6100 South Korean men aged 55 and over for two decades, men with high blood pressure who binge drank even occasionally had doulbe the risk of dying from a storke or heart attack when compared to those who didn't drink and had normal blood pressure.

What type of study is this?

Randomized Experiment

Retrospective study

Prospective study

Matched Pairs experiment.

This is a Retrospective study

Step-by-step explanation:

Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.

Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
