Answer:
the width of sue's interval will be narrower than javier's.
Step-by-step explanation:
in this problem, i do believe that sue's interval will be more narrow. in the formula,
p-hat ±
,
a larger "n" value will lead to a smaller standard error. given that the population proportion is the same for both, and the sample size is the only difference, the standard error of sue's interval will be smaller than javier's, therefore making her whole confidence interval smaller.
again, i do believe this is correct, this is what i have in my AP stat notes. hope this helps!
I don’t know I need more detail so I can answer the question
I believe there is only 1 real zero
hope this helps !!
Answer:
40
Step-by-step explanation:
The bread is 90.
28% is cookie
Then 72 %is bread and cake
Sum of bread and cake is 360
1%is 5 so cookie is 140
If sell 40 bread. Bread left is 50. Cake left is 150
Then cookie must be left 100 because the ratio of the no 1 is =to 50
Then need to sell 40 cookie so the ratio will be
50:150:100= 1:3:2
Let the number be x
(9+2x)×2= (-3x)+4
18+4x=-3x+4
4x+3x=4-18
7x=-14
x=-2
