Suppose we have a simple random sample of 400 households drawn from a city with 40,000 households . A 95% confidence interval estimate for the population mean number of children per household is [1.1,2.3]. Given this, what is the lower confidence limit for the total number of children in the city
Answer:
140
Step-by-step explanation:
46+94 = 140
9514 1404 393
Answer:
59°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠N +∠L = 180°
(a +16) +(a -18) = 180
2a = 182 . . . . . . . . . . add 2
a = 91 . . . . . . . . . . . . divide by 2
Then the measure of angle M is ...
∠M = (a+30)° = (91 +30)° = 121°
and angle K is its supplement.
∠K = 180° -121°
∠K = 59°
It would take about 5 hours for them two to work together, because if you add 2+3 you will get 5 and they are asking in total.
Hello from MrBillDoesMath!
Answer:
l = s/3.14 - r^2
Discussion:
s = 3.14 l + 3.14 r^2 => divide both sides by 3.14
s/3.14 = l + r^2 => subtract r^2 from both sides
(s/3.14) - r^2 = l
Thank you,
MrB
