Answer:
251.327412 cubic inches is the answer
Answer:
Erin ran 12.5 miles
Luis ran 7.5
In all they ran 20 miles.
Step-by-step explanation:
Erin: 5 x 3.5 = ?
Luis: 3 x 2.5 = ?
----------------------------
5 x 2.5 = 12.5 . Erin ran 12.5 miles
3 x 2.5 = 7.5 . Luis ran 7.5 miles
7.5 + 12.5 = 20 miles
They ran 20 miles all together.
Hope this helps!
Step-by-step explanation:
(a×b^-3×c^-3)⁵ / (a^-3×b⁴×c⁴)^-5
let's look at the numerator (the top) first :
a⁵×b^-15×c^-15
and now the denominator (the bottom) :
a¹⁵×b^-20×c^-20
both divided are (due to the commutative rules of multiplication we can split this first into the parts of the individual variables, and then multiply them all with each other) :
a⁵/a¹⁵ = 1/a¹⁰
b^-15 / b^-20 = b^(-15 ‐ -20) = b⁵
c^-15 / c^-20 = c⁵
so we get as result :
b⁵c⁵/a¹⁰
Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1
It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function. Tables and software are available for that purpose.
Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.
The Poisson distribution has a PMF (probability mass function)
