The two-way table shows the number of people ages 20 and 50 who belong to Group A or B. What percent of people 50 years old belong to Group A? Express your answer to the nearest whole percent. % Age 20 Age 50 Group A 19 32 Group B 40 24
I just need help figuring out how to set it up to get the answer
so basically to find what your whole would be you can add all in group a so that would be lets say x amount of people then you find out how many people are 50 from x
it's 51 ppl in group A
yeah so then what percent is 32 of 51
so % 32 --- = 100 50
64
and then you can just cross multipy
u sure?
so 3200=50x 3200/50=
yep its called a proportion
cool,so my answer is 64%
yep and that makes sense because half of 51 is about 25.5 and so that means 32 will be more than that
when I look at other people's replies they say %57
maybe they want you to add up all 50 year olds and find the percent in thatv
so thats would be 56 as total and then do the same thing just with different numbers
% 32 ---- = ----- 100 56 56x=3200 3200/56= which is 57%
cool
yeah so that might be right
I have more
okay
its basically the same thing for each one though iif youre finding % then its the same equation with different numbers
What is the mean of Variable A?
what type of chart is that?
what do you mean?
like what do they want you to find
The mean
"average"
right but the mean of what?
right but the mean of what?
