Step-by-step explanation:
a. To get 6 cents, one coin needs to be a nickel and the other coin needs to be a penny.
P = P(nickel then penny) + P(penny then nickel)
P = (4/20) (6/19) + (6/20) (4/19)
P = 12/95
b. To get 35 cents, one coin needs to be a dime and the other coin needs to be a quarter.
P = P(dime then quarter) + P(quarter then dime)
P = (3/20) (7/19) + (7/20) (3/19)
P = 21/190
c. To get 20 cents, both coins need to be dimes.
P = P(dime then dime)
P = (3/20) (2/19)
P = 3/190
Hi there!
The answer is:
Let the input be represented by X. We can see we have to multiply it by -3/4, so we get -3/4X. To find our outcome (which is represented by y), we only have to add 2 to the function.
y (outcome) = - 3/4x (income) + 2

Answer:
This is what I got, the second one, the third one, and the fifth one.
Step-by-step explanation:
Consider functions f and g such that composite g of is defined and is one-one. Are f and g both necessarily one-one. Let f : A → B and g : B → C be two functions such that g o f : A ∴ C is defined. We are given that g of : A → C is one-one.
