Actually Welcome to the Concept of the Probability.
Basically we have to know that, when there is a specific event for which a probability has to be done, there are always two possibilities that is,
Event favourable and Not Favourable.
the Sum of both always end up as 1.
thus sum of the probability distribution is 1.
Answer:
sales after 5 years is $183666
Step-by-step explanation:
exponential function standard form:
a=P(1+r)^t
where p=principal(starting amount)(125,000)
r=rate of change(0.08)
t=time(5)
so
a=125,000(1+0.08)^5
a=125,000(1.08)^5
a=125,000(1.46)
a=183666
270 divided by 10 is 27 multiply that with 36 =972
There is no picture to provide an answer to
X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
