For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:
So, we can rewrite the given expression as:
So, if 
:
Equality is met!
Answer:
Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
Compensation per hour: 20,90 / 2,75 = 7,6$
In 7 1/4 hours he will make:
7,6 * 7,25 = 55,1$
One is that they are all <em>real numbers</em>, or <em>rational numbers</em>.
