Step-by-step explanation:
c.
A deck of cards has 52 cards. There are cards of 4 suits- Spades, Hearts, Diamonds and Clubs.
So, there are 52/4= 13 cards of each suit.
Among these 13 cards, there are 3 picture cards or face cards as they are called. These are the Jack, Queen and King cards.
So, the number of total picture cards = 4*3 = 12
the number of cards are 52
theoretical probability formula: P = favorable events/ possible events
P = 12 / 52
P = 3 / 13
d.
there are four aces and four sevens in the deck
so favorable events = 4 + 4 = 8
possible eventas = 52
P = 8 / 52
P = 2 / 13
Formula= Base times height divided by 2
6 x 7= 42
42/ 2
answer= 21
Answer:
7
Step-by-step explanation:
Set up an equation using slope intercept form.
y = mx + b
75 = 8x + 15
Solve.
75 = 8x + 15
-15 -15
60 = 8x
7.5
Round down as it is dealing with money and he would not have enough to purchase an 8th grocery.
7 is the final answer.
Hope this helps!
