Step-by-step explanation:
Answer:
The classification of the set of circumstances is presented in the following subsections of the understanding.
Step-by-step explanation:
A 7-year health research project revealed that individuals for whom the mom took DES throughout pregnancy seem to have been twice as probable as women for whom the mothers didn't use the medication to establish tissue irregularities that could cause cancer.
(a)
Women with whom the mothers have taken DES throughout pregnancy as well as women where its mothers haven't taken DES during pregnancy.
(b)
The information collected seems to have been a sample or survey.
(c)
A sampling unit of 3980 (women) showed that performance 63 industrialized tissue irregularities that could contribute to disease (cancer) in the proportion of females with whom the mom brought the powerful DES all through pregnancy.
The proportion of abnormalities in tissues established by females does seem to be:
= 
= 
Of every thousand women, 15.8 established tissue abnormalities.
Maximum revenue happens when 950 sandwiches are sold. When more or less sandwiches are sold revenue decreases by a constant amount.
We are told that revenue decreased by $45. We can use this information to calculate the amount of sandwiches.
number_of_sandwiches = total_revenue_change / revenue_change_per_sandwich
number_of_sandwiches = $45 / $0.10
number_of_sandwiches = 450
Number of sold sandwiches is either 450 more or 450 less than the amount of maximum revenue.
Possible numbers of sold sandwiches are:
number = 950 - 450 = 500
number = 950 + 450 = 1400
Answer:
