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!
Answer:
D. 18 1/8
Step-by-step explanation:
The three 1/3’s add up to 1. The 7 and 9 add up to 16. Add the 1 to that and you get 17. Then change the 1/2 to 4/8 and add that to the 5/8. You then get 1 and 1/8. Then you add that to the 17.
Answer is D since the polygon is inside the circle !!!
Answer:
The rate of change for the linear model = 15.25
Step-by-step explanation:
Given:
A linear model where 
represents number of hours bowled on one lane and 
represents the total cost of bowling.
This point shows that the cost of bowling for 2 hours = $34
This point shows that the cost of bowling for 3 hours = $49.25
To find the rate of change in the given model we need to find the slope of the line 
using the given points.
∴ the rate of change for the linear model = 15.25
This shows that the bowling alley charges its customers an hourly rate of $15.25.
Y=all the dog toys Lilly has.
z= toys that are red.
1/3(y)=z
1/3(y)=6
3x1/3(y)=6(3)
y=18
Lily will have 18 dog toys.
