Answer:
3200
Step-by-step explanation:
Replace the variables with their values and do the arithmetic.
(4·5)²·8 = 20²·8 = 400·8 = 3200
Answer:
131.87-23.24=108.63
Step-by-step explanation:
To solve this problem, let's line up the problem. To make it easier, we can start by ignoring the decimals.
13187
- 2324
______
10863
And then, since there were decimals in the first place, we have to add them back in.
10863→108.63

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
