Answer:
12.5
Step-by-step explanation:
square root of 10^2 - 8^2 = 6 gives us missing side
sin^-1(8/10) = 53.13 gives us half of the angle
90-53.13 = 36.869 gives us the angle of the triangle on the right
tan(36.869) x 6 = 4.5
4.5 + 8 = 12.5
Hope that helps,
Good Luck! x
Answer:
a) 0.264
b) 48 cubit light-years
Step-by-step explanation:
For calculating a) What is the probability of 3 or more stars in 16 cubic light years?
a)
λ= 1 star/16 cubic light-years
t= measure t in units of 16 cubic light years.
E(Y) = λ t = (1/16)(16) = 1 star
P(X>=2) = 1 - P(X<2)
= 1 - [e^-1 + (e^-1)(1)/1!]
= 0.264
b)
P(X≥1) = 1 - P(X=0)
= 1 - e^-μ
0.95 = 1 - e^-μ
e^-μ = 1 - 0.95
e^-μ = 0.05
ln(e^-μ) = ln(0.05)
-μ = -3
μ = 3
Therefore 3 x 16 = 48 cubic light years of space
No. A square has equal sides that are perpendicular and parallel. I'm guessing this room resembles some other figure.

Answer: 9) K ||| 10) H
9) This is because at first the probability is 5/14 but once we take one red out we have to account for that so the probability the second time will be 4/13
10) Ming=2/5 Tyrel=5/8
If ming plays 200 they can expect to win (2/5 x 200) = 80
If tyrel plays 200 they can expect to win (5/8 x 200) = 125
To find how how many more tyrel will win than ming just do 125 - 80 = 45
Hope this helps :)
