Answer:
The probability is 1/15 or 6.67%
Step-by-step explanation:
step 1
Find the probability that when she shakes the piggy bank a half-dollar fall out
P=2/15
step 2
Find the probability that when she shakes the piggy bank a dime fall out
P=7/14
step 3
Find he probability that when she shakes the piggy bank a half-dollar and then a dime fall out
P=(2/15)(7/14)=1/15
Convert to percentage
(1/15)*100=6.67%

Answer:
Second choice
Step-by-step explanation:
To find inverses, we follow the steps:
1. exchange variables x and y
2. solve for y in terms of x.
The resulting function is the inverse.
Take case 2 as an example:
f(x) = y = 2x-3
1. exchange x and y : x=2y-3
2. solve for y: x+3=2y => y=(x+3)/2 = g(x)
Since the inverse of f(x) is g(x)=(x+3)/2, the second choice is the answer.
