Arecent study followed 900,000 us adults from 1982 to 1998. at baseline, all participants were screened and determined to be cancer free and their body mass index (bmi) was calculated. body mass index is a measure of obesity that is calculated using a person's height and weight. subjects were separated into the following groups according to their bmi: (a) normal weight, (b) slightly overweight, (c) moderately overweight and (d) greatly overweight. 57,145 deaths from cancer occurred in the population during the follow-up period. the following results were seen for men and women when the heaviest members of the cohort were compared to those with normal weight:
men: risk ratio of cancer death= 1.5 95% confidence interval= 1.1-2.1 women: risk ratio of cancer death= 1.6 95% confidence interval= 1.4-1.9
are the results bolded above confounded by gender? why?

Someone answer this asap rn for ! a discount storeβs prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
