Using it's concept, the probability of choosing a number that is a multiple of 9 is of 0.111.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
From 1 to 81, there are 81 numbers, of which 81/9 = 9 are multiples of 9, hence, considering that 81 is the number of total outcomes and that 9 is the number of desired outcomes, the probability is given the following division:
p = 9/81 = 1/9 = 0.111.

Answer:
39420
Step-by-step explanation:
Multiply 2% by 365, then you get 7.3, multiply 7.3 by 3, then you get 21.9, then last step, multiply 21.9 by 1800$
Answer:
10)$38.50
11)D
Step-by-step explanation:
10) n = no. of rides
f(n) + g(n) = 1 + 2.5n
when n=15, 1 + 2.5(15)
= $38.50
11)f(x) = 4x³+3x²-5x+20
g(x) = 9x³-4x²+10x-55
(g-f)(x)=9x³-4x²+10x-55-(4x³
+3x²-5x+20)
= 9x³-4x²+10x-55-4x³
-3x²+5x-20
= 5x³-7x²+15x-75
