Answer:
37.68 inches
Step-by-step explanation:
The formula for the circumference of a circle is 2πr.
The radius is 6, and 6⋅2 = 12 (diameter).
3.14 = pi.
12 ⋅ 3.14 = 37.68
Whichever answer is closest to 37.68 is your answer!
f(n)= f(n-1) · 0.6+48, n>0
Answer:
The margin of error at 90% confidence is 0.5133 gram.
Step-by-step explanation:
Margin of error (E) = (critical value × sample standard deviation) ÷ sqrt(n)
sample standard deviation = 1.5 grams
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
n (sample size) = 25
degree of freedom = n - 1 = 25 - 1 = 24
critical value (t) corresponding to 24 degrees of freedom and 10% significance level is 1.711
E = (1.711×1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 gram
Answer:
$24
Step-by-step explanation:
Since you know 5 tickets equal to $60, and you want to find the cost of one ticket, you would divide 60 by 5. 60/5=12. So each ticket costs 12 dollars. But you want to find the cost of two. So multiply $12 by two to get $24 dollars per two tickets.
I believe the answer is 32. I'm sorry if I'm wrong
