Answer: 8:05
Step-by-step explanation:
(2v-7x)^2=
(2v-7x)(2v-7x) Next step, FOIL.
2v^2-14vx-14vx+49x^2
2v^2-28vx+49x^2
Not sure how you're going to want to re-write that, but that should be the basic answer
Answer:
p(x = 3, λ = 5) = 0.14044
Step-by-step explanation:
Given
λ = 5 (the average number of tracks per square centimeter)
ε = 2.718 (constant value)
x = 3 (the variable that denotes the number of successes that we want to occur)
p(x,λ) = probability of x successes, when the average number of occurrences of them is λ
We can use the equation
p(x,λ) = λˣ*ε∧(-λ)/x!
⇒ p(x = 3, λ = 5) = (5)³*(2.718)⁻⁵/3!
⇒ p(x = 3, λ = 5) = 0.14044
