Answer:
a) 0.25
b) 0.75
Step-by-step explanation:
The formula to find probability is

Here as deck pf playing cards has 52 cards.
So total outcomes = 52
a)
A deck of cards has 13 hearts.
Favorable outcomes = 13
Probability of drawing a Heart

b)
A deck of cards has 13 cards of clubs.
So the cards which are not clubs = 52-13=39
Hence favorable outcomes = 39
Probability of not drawing a club card

Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
