Shouldn’t there be a total of 61 people being surveyed?The 6 won’t be in the circles but it’ll be in the diagram.Since the qn states that there’s no people with both (from what i’m assuming from the qn)We will group those with a brother in one circle and call it “A” and those with a sister as another circle and call it “B”.So the diagram should look something like this ⬇️ don’t mind my handwriting
7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
20 weeks.
Bar graph: Start with zero, and the next ones (bars) will all increase by a 15 interval over the period of 20 weeks. So 1 bar per week, and there are 20 weeks, with each bar having a 15$ profit difference. Sorry, can't draw it here.
equation: 15x=300
15/(15x=300)/15
x=20
Answer: It would be 20
