Questions a-d are based on the following information the death rate per 100,000 for breast cancer is 25 among hormone replacement therapy (hrt) users and 15 among non-hrt users. the prevalence of hrt use in the population is 70% make the following calculations. (3 points each) the relative risk of dying for an hrt user compared to a non-user is: a b. what is the excess risk of breast cancer in those who used hrt? what is the percentage of breast cancer in the hrt users that can be attributed to hrt? what is the percentage of breast cancer in the population that can be attributed to hrt? d. 19

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
