tell me what letters you have so far
ok well for A i have 15
For D i have 10
And for letter I, I have 100
so far so good
Oh wait nevermind D cant be 15 cuz at the end it says 40 ppl like hatchbacks
Oh wait! B is 40 then right?
you already said D = 10
B isn't 40
Oh so where does the 40 go if A is 15?
`There are 40 people who liked hatchbacks` this goes in the "liked hatchbacks" row and "total" column. Basically saying "the total of people who liked hatchbacks is 40"
ie, C = 40
Oh so B is 25?
Because 40-15= 25
G = 25 ... correct H = 60 ... not correct F = 45 ... not correct
you may have mixed up H and F somehow?
but the values don't swap (not entirely)
No cuz 25+35= 60
I am confused now...
I thought E was 35 and B was 25....35 + 25= 60?
hint: G+H = 100
another hint: C+F = 100
Ok so can we just review that.... A=15 B= 25 When we add those two we get C=40 D=10 E=??? What did we say E was? is it 50? when we add 50+10 we get F=100 G=25 H=i guess 75, if e is 50 25+75 is I=100
F is not 100
Oh i meant 60 sorry
G+H = 100 25+H = 100 solve for H to get H = 75
F = 60, correct
cuz 50+10 is 60...
or you can solve for F in C+F = 100 40+F = 100 either way, F = 60
Uh lol ok thank you now part B
So the number would be 50, right? And then we divide that by 100. so 0.50 or 50% is that right?
you have to consider the totals for those who don't like hatchbacks or sedans
number who don't like sedans OR hatchbacks = (number who don't like sedans) + (number who don't like hatchbacks) - (number who don't like both)
Oh so 75 or 75%
close but no
I thought it was the total?
number who don't like sedans = 75 number who don't like hatchbacks = 60 number who don't like both = 50 number who don't like sedans OR hatchbacks = (number who don't like sedans) + (number who don't like hatchbacks) - (number who don't like both)
Ohhh! okk so...
ok wow I finally understand this now?
the subtle difference is that 50% would be if it said "what percentage didn't like BOTH types" or "what percentage didn't like sedans AND hatcbacks". They didn't just hate 1 car. They hate both cars.
Ok i get it now.
in part C, you simply compare the values of H and F
so then it would be yes
yes since H > F
I cant thank you any more! I have one more question.. i am going to open it up in a few minutes
