Answer:
what is the full question?
Step-by-step explanation:
12.7
Using the Pythagorean theorem, you can easily calculate the length of BC.
So:
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So:
BC/sin(55) = CD/sin(90)
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
Is -1.393 the significance level and if so what’s the degree of freedom?
10 minutes I'm pretty sure. My calculations may be off but at least I tried
Answer:
22 students
Step-by-step explanation:
218 students - 20 students = 198 students on buses
198 students / 9 buses = 22 students per bus
