My guess is b but it really depends on the situation
Answer:
6907
Step-by-step explanation:
reqired sample size is 
where,
crititical value (t) = 1.96 for 95% conf.
margin of error (b) = 0.25
standard deviation (s) = 10.6
Za/2 = Z0.025 = 1.96
n ≥ 
n >= 6906.27
n = 6907
In the question above, the given statement represent the answer as (6907).
Answer:
Aidan can expect to save about $17.63 each week.
Step-by-step explanation:
We have an equation: y = 17.63x + 27.52. This equation is in <em>slope-intercept form</em>. In slope-intercept form, the value before the x (in this case, 17.63) is the slope, and the value added to the slope (in this case, 27.52) is the y-intercept.
Right now, though, we only need to focus on the slope. The slope represents a change in y over a change in x. Our y-values represent <em>total amount saved</em>, and our x-values represent <em>number of weeks</em>. Y over x... so, total amount saved over a certain number of weeks.
The first answer seems to match this the best. Remember that the slope represents how much is saved per week, and our slope is 17.63. So, the first answer (Aidan can expect to save about $17.63 each week) is correct. If you have any more questions or that was confusing at all, let me know! :)
This equation in numerical form is
8+b/20>4.
Answer:
25
Step-by-step explanation:
The students on the screen is the difference between the total number of students she zoomed and the students in the waiting area
37 - 12 = 25
